Re: Roassal Issue with Text Displaying

abergel
Mixing capital letters seems to cause the problem

Roassal2 seems to be not affected by this behavior.

The odd font behavior you have shown in the previous emails, seems to happens after some time… I have seen it in the past.

The strange thing is that if you debug, it seems that the code is basically the same in both cases. I am stuck. Ideas?

Look at the level of the canvas's creation, maybe the properties are not the same...

And I have no problem in font displaying !

In the newer version, they have implemented the text rendering with NativeBoost.

As Roassal2 works fine with the newer version, I don't know if this is a problem with Roassal or with Athens-Cairo.
Maybe you should look at it ?

Hi,

The following code solve the issue under Roassal2 (Tested under Linux) :


TRLabelShape class>>getFontForSize: aNumber
   ^ LogicalFont familyName: StandardFonts defaultFont familyName pointSize: aNumber

For Roassal, the fonts used are the same that in Roassal2 so I don't think that is the problem.

But it seems that the Athens Font Renderer has been changed (CairoFreetypeFontRenderer) the 4 February (Athens-Cairo-MarcusDenker.62).
This the only thing I see with my knowledges on Roassal. And I don't know how to solve it. Maybe does Alexandre know ?

I have found a solution to fix the bug:

TRLabelShape class>>getFontForSize: aNumber
   ^ LogicalFont familyName: StandardFonts defaultFont familyName pointSize: aNumber

In this, it creates an other font with the good size. Because if you don't do that, you always have the same problem.

"StandardFonts defaultFont familyName" should be enough to get the font to use. Maybe we have to change something else in Roassal2.

The font display issue..

 RTDowserExample new coolStuff :

That is under Linux. It's not very readable.

And I think there is the same issue with W7
If you want some help, I can. But I need some pointers :)

I have the impression, that the class TRLabelShape has to be improved.
For example, consider the following method:
-=-=-=-=-=-=-=-=-=-=-=-=
TRLabelShape class>>getFontForSize: aNumber
       ^ LogicalFont familyName: 'Arial' pointSize: aNumber
-=-=-=-=-=-=-=-=-=-=-=-=

The font name is hardcoded, which is not a good idea since you may have a different font set on your machine. It would be great to use the installed font, used by Pharo.

That a good idea ! Because under Linux, the Arial font doesn't exists....


But with this :
LogicalFont familyName: 'Source Sans Pro' pointSize: 12
You have :

I will search how to use the system fonts.
By the way, have you tried: RTExample new rotatingLabelsAnimated

That doesn't work :( rotatingLabelsAnimated is not a valid message to a RTExample ...

Hi!

I have spent a lot of time on trying to understand font, and many bugs are
still there. I would indeed be happy to have help on this...

Why trying to use Roassal2 instead? Your code will stay the same, but it
will directly use Athens.

Look at the level of the canvas's creation, maybe the properties are not the same...

And I have no problem in font displaying !

In the newer version, they have implemented the text rendering with NativeBoost.

As Roassal2 works fine with the newer version, I don't know if this is a problem with Roassal or with Athens-Cairo.
Maybe you should look at it ?

Hi,

The following code solve the issue under Roassal2 (Tested under Linux) :


TRLabelShape class>>getFontForSize: aNumber
   ^ LogicalFont familyName: StandardFonts defaultFont familyName pointSize: aNumber

For Roassal, the fonts used are the same that in Roassal2 so I don't think that is the problem.

But it seems that the Athens Font Renderer has been changed (CairoFreetypeFontRenderer) the 4 February (Athens-Cairo-MarcusDenker.62).
This the only thing I see with my knowledges on Roassal. And I don't know how to solve it. Maybe does Alexandre know ?

I have found a solution to fix the bug:

TRLabelShape class>>getFontForSize: aNumber
   ^ LogicalFont familyName: StandardFonts defaultFont familyName pointSize: aNumber

In this, it creates an other font with the good size. Because if you don't do that, you always have the same problem.

"StandardFonts defaultFont familyName" should be enough to get the font to use. Maybe we have to change something else in Roassal2.

Which issue?

The font display issue..

 RTDowserExample new coolStuff :

<ghcgceef.png>
That is under Linux. It's not very readable.

And I think there is the same issue with W7
If you want some help, I can. But I need some pointers :)

I have the impression, that the class TRLabelShape has to be improved.
For example, consider the following method:
-=-=-=-=-=-=-=-=-=-=-=-=
TRLabelShape class>>getFontForSize: aNumber
       ^ LogicalFont familyName: 'Arial' pointSize: aNumber
-=-=-=-=-=-=-=-=-=-=-=-=

The font name is hardcoded, which is not a good idea since you may have a different font set on your machine. It would be great to use the installed font, used by Pharo.

That a good idea ! Because under Linux, the Arial font doesn't exists....


But with this :
LogicalFont familyName: 'Source Sans Pro' pointSize: 12
You have :
<ijdgccca.png>

I will search how to use the system fonts.
By the way, have you tried: RTExample new rotatingLabelsAnimated

That doesn't work :( rotatingLabelsAnimated is not a valid message to a RTExample ...
:-)

Hi!

I have spent a lot of time on trying to understand font, and many bugs are
still there. I would indeed be happy to have help on this...

Why trying to use Roassal2 instead? Your code will stay the same, but it
will directly use Athens.

Hi,

Maybe you should ask in the Pharo mailing list ?

At this moment, essentially all visualizations containing text are broken (Roassal, Roassal2, GraphET). This is a show stopper.

I have found a solution to fix the bug:

TRLabelShape class>>getFontForSize: aNumber
   ^ LogicalFont familyName: StandardFonts defaultFont familyName pointSize: aNumber

In this, it creates an other font with the good size. Because if you don't do that, you always have the same problem.

"StandardFonts defaultFont familyName" should be enough to get the font to use. Maybe we have to change something else in Roassal2.

No problem to use Roassal 2 instead !

But I have the same issue on the examples.

Which issue?

The font display issue..

 RTDowserExample new coolStuff :

<ghcgceef.png>
That is under Linux. It's not very readable..

And I think there is the same issue with W7
If you want some help, I can. But I need some pointers :)

I have the impression, that the class TRLabelShape has to be improved.
For example, consider the following method:
-=-=-=-=-=-=-=-=-=-=-=-=
TRLabelShape class>>getFontForSize: aNumber
       ^ LogicalFont familyName: 'Arial' pointSize: aNumber
-=-=-=-=-=-=-=-=-=-=-=-=

The font name is hardcoded, which is not a good idea since you may have a different font set on your machine. It would be great to use the installed font, used by Pharo.

That a good idea ! Because under Linux, the Arial font doesn't exists....


But with this :
LogicalFont familyName: 'Source Sans Pro' pointSize: 12
You have :
<ijdgccca.png>

I will search how to use the system fonts.
By the way, have you tried: RTExample new rotatingLabelsAnimated

That doesn't work :( rotatingLabelsAnimated is not a valid message to a RTExample ...
:-)
Alexandre



Cheers,

Vincent

Hi!

I have spent a lot of time on trying to understand font, and many bugs are
still there. I would indeed be happy to have help on this...

Why trying to use Roassal2 instead? Your code will stay the same, but it
will directly use Athens.

Cheers,
Alexandre

Hello everyone,

Under the latest version of Moose, I am confronted to some problems of

A first example :

A second example :

And if I zoom in or out, the text is correctly displayed...

Re: Roassal Issue with Text Displaying

Yes, please :)

@Vincent: I think at this point you know the most about the issue. Would you like to take charge of it and bring it on the Pharo mailing list?

The odd font behavior you have shown in the previous emails, seems to happens after some time… I have seen it in the past.

Hi,

I tried to debug a bit more.

First, I noticed that Roassal was using the FreeTypeFont and Trachel the LogicalFont. I now changed Roassal to also use the LogicalFont. This did not solve the issue, but it does ease the comparison. (Just ensure that you clean the cached fonts from ROFontOrganizerAthens if you already worked in the same image before loading the new code)

Then, I noticed that even Trachel does not yet quite work: some letters still appear larger than others. However, at least in the case of Trachel, the width of the characters correspond to the size of the rendering (and this seems to still be a problem in Roassal).

See attachments:

The strange thing is that if you debug, it seems that the code is basically the same in both cases. I am stuck. Ideas?

Look at the level of the canvas's creation, maybe the properties are not the same...

And I have no problem in font displaying !

In the newer version, they have implemented the text rendering with NativeBoost.

As Roassal2 works fine with the newer version, I don't know if this is a problem with Roassal or with Athens-Cairo.
Maybe you should look at it ?

The following code solve the issue under Roassal2 (Tested under Linux) :

For Roassal, the fonts used are the same that in Roassal2 so I don't think that is the problem.

But it seems that the Athens Font Renderer has been changed (CairoFreetypeFontRenderer) the 4 February (Athens-Cairo-MarcusDenker.62).
This the only thing I see with my knowledges on Roassal. And I don't know how to solve it. Maybe does Alexandre know ?

Yes I will.

But I was trying to load Roassal in Pharo and try to reproduce the issue
(because I think that there are going to do !).

Gofer new smalltalkhubUser: 'ObjectProfile'
project: 'Roassal';
package: 'ConfigurationOfRoassal';
load.
(Smalltalk at: #ConfigurationOfRoassal) load

And when I click on the Select Canvas button of the RoassalEasel
Visualisation I get an error :
StrikeFont doesNotUnderstand: #glyphRenderOn:

Re: Roassal Issue with Text Displaying

Tudor Girba-2
That's because you have to install free type fonts.

Yes Vincent. Can you do it? The only thing I can do is forwarding the picture to the pharo mailing list and crying for help
Yes I will.

But I was trying to load Roassal in Pharo and try to reproduce the issue (because I think that there are going to do !).

Gofer new smalltalkhubUser: 'ObjectProfile'
project: 'Roassal';
package: 'ConfigurationOfRoassal';
load.

And when I click on the Select Canvas button of the RoassalEasel Visualisation I get an error :

Hi,

I tried to debug a bit more.

First, I noticed that Roassal was using the FreeTypeFont and Trachel the LogicalFont. I now changed Roassal to                               also use the LogicalFont. This did not solve the issue, but it does ease the comparison. (Just ensure that you clean the cached fonts from ROFontOrganizerAthens if you already worked in the same image before loading the new code)
Then, I noticed that even Trachel does not yet quite work: some letters still appear larger than others. However, at least in the case of Trachel, the width of the characters correspond to the size of the rendering (and this seems to still be a problem in Roassal).

See attachments:

In this, it creates an other font with the good size. Because if you don't do that, you always have the same problem.

"StandardFonts defaultFont familyName" should be enough to get the font to use. Maybe we have to change something else in Roassal2.

That's strange..

I am on Ubuntu x64 and I have the same issue on W7.

Cheers,

Vincent

Fwd: Text Displaying issue with Roassal

Vincent Blondeau
In reply to this post by Tudor Girba-2
Hi Pharoers,

We are encounter a problem with text displaying under Roassal.
Roassal is a Moose tool to make some graphics visualisations, principally graphs.
Some visualisations are displaying some text, like :

- ROMondrianExample new centeredText
- ROMondrianExample new temporaryEdges
- ROMondrianExample new labeledRectangle

They use AthensCanvas to render.

Since the beginning of February, we experiment very strange problems with font displaying. See by yourself :

What we expect :

What we have :

You can see that the letters in each word are not of the same size.
(To reproduce do : "ROMondrianExample new labeledRectangle" in a fresh Moose image : https://ci.inria.fr/moose/job/moose-5.0/lastSuccessfulBuild/artifact/moose-5.0.zip)

We thought it was a font problem. So we updated the fonts to use this one :
LogicalFont familyName: StandardFonts defaultFont familyName pointSize: aSize
which is the default system font. (The fonts are located in ROFontOrganizerAthens).

But the problem was not solved.

After some searches, we saw that Roassal (via the ROAthensCanvas) uses AthensCairoCanvas and this class has been changed begin February to use native boost.
The closed issue related is :

12765 Athens font rendering missing letters and missizing others
    https://pharo.fogbugz.com/f/cases/12765

That should resolve the problem instead of created one ;)


So if we load the older packages of Athens-Core and Athens-Cairo (before the issue resolution):

Name: Athens-Core-MarcusDenker.34
Author: MarcusDenker
Time: 5 July 2013, 10:59:47.206954 am
UUID: e844b2d4-b091-42a4-9be0-17101dcdbd30
Ancestors: Athens-Core-MarcusDenker.33, Athens-Core-ErwanDouaille.33

Name: Athens-Cairo-MarcusDenker.51
Author: MarcusDenker
Time: 26 August 2013, 4:03:06.190096 pm
UUID: 9e1bfddb-67f7-4a36-864d-11060b8b6881
Ancestors: Athens-Cairo-SebastianTleye.50

we have no problem of font displaying !

The question is :
What we should adapt in Roassal to support this new implementation of Athens ? Or is Athens (by the native boost primitives) broken ?

Thanks in advance !


Vincent BLONDEAU

There is a bug opened. A temporary solution is to do :
CairoBackendCache flush

Tell me if the problem is solved from your points of view ?

Re: Roassal Issue with Text Displaying

Tudor Girba-2
It does not.

I tried this on Windows 7:
CairoBackendCache flush.
RTView new 
add: (RTLabel elementOn: (String newFrom: ($a to: $z)));
yourself

And the problem is still there.

What exactly do you do?

Tell me if the problem is solved from your points of view ?

First, I noticed that Roassal was using the FreeTypeFont and Trachel the LogicalFont. I now changed Roassal to                               also use the LogicalFont. This did not solve the issue, but it does ease the comparison. (Just ensure that you clean the cached fonts from ROFontOrganizerAthens if you already worked in the same image before loading the new code)
Then, I noticed that even Trachel does not yet quite work: some letters still appear larger than others. However, at least in the case of Trachel, the width of the characters correspond to the size of the rendering (and this seems to still be a problem in Roassal).

In this, it creates an other font with the good size. Because if you don't do that, you always have the same problem.

"StandardFonts defaultFont familyName" should be enough to get the font to use. Maybe we have to change something else in Roassal2.

There is a bug opened. A temporary solution is to do :
CairoBackendCache flush

Tell me if the problem is solved from your points of view ?

Hi,

I tried to debug a bit more.

First, I noticed that Roassal was using the FreeTypeFont and Trachel the LogicalFont. I now changed Roassal to                               also use the LogicalFont. This did not solve the issue, but it does ease the comparison. (Just ensure that you clean the cached fonts from ROFontOrganizerAthens if you already worked in the same image before loading the new code)
Then, I noticed that even Trachel does not yet quite work: some letters still appear larger than others. However, at least in the case of Trachel, the width of the characters correspond to the size of the rendering (and this seems to still be a problem in Roassal).

See attachments:

The strange thing is that if you debug, it seems that the code is basically the same in both cases. I am stuck. Ideas?
Look at the level of the canvas's creation, maybe the properties are not the same...

And I have no problem in font displaying !

In the newer version, they have implemented the text rendering with NativeBoost.

As Roassal2 works fine with the newer version, I don't know if this is a problem with Roassal or with Athens-Cairo.
Maybe you should look at it ?

The following code solve the issue under Roassal2 (Tested under Linux) :

For Roassal, the fonts used are the same that in Roassal2 so I don't think that is the problem.

But it seems that the Athens Font Renderer has been changed (CairoFreetypeFontRenderer) the 4 February (Athens-Cairo-MarcusDenker.62).
This the only thing I see with my knowledges on Roassal. And I don't know how to solve it. Maybe does Alexandre know ?

In this, it creates an other font with the good size. Because if you don't do that, you always have the same problem.

"StandardFonts defaultFont familyName" should be enough to get the font to use. Maybe we have to change something else in Roassal2.

The font display issue..

That is under Linux. It's not very readable..


And I think there is the same issue with W7
If you want some help, I can. But I need some pointers :)

I have the impression, that the class TRLabelShape has to be improved.
For example, consider the following method:
-=-=-=-=-=-=-=-=-=-=-=-=
TRLabelShape class>>getFontForSize: aNumber
        ^ LogicalFont familyName: 'Arial' pointSize: aNumber
-=-=-=-=-=-=-=-=-=-=-=-=

The font name is hardcoded, which is not a good idea since you may have a different font set on your machine. It would be great to use the installed font, used by Pharo.

That a good idea ! Because under Linux, the Arial font doesn't exists.....



But with this :
LogicalFont familyName: 'Source Sans Pro' pointSize: 12
You have :

I will search how to use the system fonts.
By the way, have you tried: RTExample new rotatingLabelsAnimated

That doesn't work :( rotatingLabelsAnimated is not a valid message to a RTExample ...

Yes Vincent. Can you do it? The only thing I can do is forwarding the picture to the pharo mailing list and crying for help

There is a bug opened. A temporary solution is to do :
CairoBackendCache flush

Tell me if the problem is solved from your points of view ?

Hi,

I tried to debug a bit more.

First, I noticed that Roassal was using the FreeTypeFont and Trachel the LogicalFont. I now changed Roassal to                               also use the LogicalFont. This did not solve the issue, but it does ease the comparison. (Just ensure that you clean the cached fonts from ROFontOrganizerAthens if you already worked in the same image before loading the new code)
Then, I noticed that even Trachel does not yet quite work: some letters still appear larger than others. However, at least in the case of Trachel, the width of the characters correspond to the size of the rendering (and this seems to still be a problem in Roassal).

See attachments:

The strange thing is that if you debug, it seems that the code is basically the same in both cases. I am stuck. Ideas?
Look at the level of the canvas's creation, maybe the properties are not the same...

Ancestors: Athens-Cairo-SebastianTleye.50

And I have no problem in font displaying !

In the newer version, they have implemented the text rendering with NativeBoost.

As Roassal2 works fine with the newer version, I don't know if this is a problem with Roassal or with Athens-Cairo.
Maybe you should look at it ?

Cheers,

Hi,

The following code solve the issue under Roassal2 (Tested under Linux) :


TRLabelShape class>>getFontForSize: aNumber
    ^ LogicalFont familyName: StandardFonts defaultFont familyName pointSize: aNumber

For Roassal, the fonts used are the same that in Roassal2 so I don't think that is the problem.

But it seems that the Athens Font Renderer has been changed (CairoFreetypeFontRenderer) the 4 February (Athens-Cairo-MarcusDenker.62).
This the only thing I see with my knowledges on Roassal. And I don't know how to solve it. Maybe does Alexandre know ?

Everything should be treated in Trachel I have the impression.
I have found a solution to fix the bug:

TRLabelShape class>>getFontForSize: aNumber
    ^ LogicalFont familyName: StandardFonts defaultFont familyName pointSize: aNumber

In this, it creates an other font with the good size. Because if you don't do that, you always have the same problem.

"StandardFonts defaultFont familyName" should be enough to get the font to use. Maybe we have to change something else in Roassal2.

No problem to use Roassal 2 instead !

But I have the same issue on the examples.

Which issue?

The font display issue..

  RTDowserExample new coolStuff :

<ghcgceef.png>
That is under Linux. It's not very readable..


And I think there is the same issue with W7
If you want some help, I can. But I need some pointers :)

I have the impression, that the class TRLabelShape has to be improved.
For example, consider the following method:
-=-=-=-=-=-=-=-=-=-=-=-=
TRLabelShape class>>getFontForSize: aNumber
        ^ LogicalFont familyName: 'Arial' pointSize: aNumber
-=-=-=-=-=-=-=-=-=-=-=-=

The font name is hardcoded, which is not a good idea since you may have a different font set on your machine. It would be great to use the installed font, used by Pharo.

That a good idea ! Because under Linux, the Arial font doesn't exists.....



But with this :
LogicalFont familyName: 'Source Sans Pro' pointSize: 12
You have :
<ijdgccca.png>

I will search how to use the system fonts.
By the way, have you tried: RTExample new rotatingLabelsAnimated

That doesn't work :( rotatingLabelsAnimated is not a valid message to a RTExample ...
:-)

Hi!

I have spent a lot of time on trying to understand font, and many bugs are
still there. I would indeed be happy to have help on this...

Why trying to use Roassal2 instead? Your code will stay the same, but it
will directly use Athens.

That's strange..

I am on Ubuntu x64 and I have the same issue on W7.

Yes Vincent. Can you do it? The only thing I can do is forwarding the picture to the pharo mailing list and crying for help

There is a bug opened. A temporary solution is to do :
CairoBackendCache flush

Tell me if the problem is solved from your points of view ?

Hi,

I tried to debug a bit more.

First, I noticed that Roassal was using the FreeTypeFont and Trachel the LogicalFont. I now changed Roassal to                               also use the LogicalFont. This did not solve the issue, but it does ease the comparison. (Just ensure that you clean the cached fonts from ROFontOrganizerAthens if you already worked in the same image before loading the new code)
Then, I noticed that even Trachel does not yet quite work: some letters still appear larger than others. However, at least in the case of Trachel, the width of the characters correspond to the size of the rendering (and this seems to still be a problem in Roassal).

See attachments:

<Mail Attachment.png>

<Mail Attachment.png>

The strange thing is that if you debug, it seems that the code is basically the same in both cases. I am stuck. Ideas?
Look at the level of the canvas's creation, maybe the properties are not the same...

Hi,

For Roassal, I loaded the older packages of Athens-Core and Athens-Cairo :

Ancestors: Athens-Cairo-SebastianTleye.50

And I have no problem in font displaying !

In the newer version, they have implemented the text rendering with NativeBoost.

As Roassal2 works fine with the newer version, I don't know if this is a problem with Roassal or with Athens-Cairo.
Maybe you should look at it ?

Cheers,

Vincent

Hi,

The following code solve the issue under Roassal2 (Tested under Linux) :


TRLabelShape class>>getFontForSize: aNumber
    ^ LogicalFont familyName: StandardFonts defaultFont familyName pointSize: aNumber

For Roassal, the fonts used are the same that in Roassal2 so I don't think that is the problem.

But it seems that the Athens Font Renderer has been changed (CairoFreetypeFontRenderer) the 4 February (Athens-Cairo-MarcusDenker.62).
This the only thing I see with my knowledges on Roassal. And I don't know how to solve it. Maybe does Alexandre know ?

I have found a solution to fix the bug:

TRLabelShape class>>getFontForSize: aNumber
    ^ LogicalFont familyName: StandardFonts defaultFont familyName pointSize: aNumber

In this, it creates an other font with the good size. Because if you don't do that, you always have the same problem.

"StandardFonts defaultFont familyName" should be enough to get the font to use. Maybe we have to change something else in Roassal2.

Which issue?

The font display issue..

  RTDowserExample new coolStuff :

That is under Linux. It's not very readable..


And I think there is the same issue with W7
If you want some help, I can. But I need some pointers :)

I have the impression, that the class TRLabelShape has to be improved.
For example, consider the following method:
-=-=-=-=-=-=-=-=-=-=-=-=
TRLabelShape class>>getFontForSize: aNumber
        ^ LogicalFont familyName: 'Arial' pointSize: aNumber
-=-=-=-=-=-=-=-=-=-=-=-=

The font name is hardcoded, which is not a good idea since you may have a different font set on your machine. It would be great to use the installed font, used by Pharo.

That a good idea ! Because under Linux, the Arial font doesn't exists.....



But with this :
LogicalFont familyName: 'Source Sans Pro' pointSize: 12
You have :
<ijdgccca.png>

I will search how to use the system fonts.
By the way, have you tried: RTExample new rotatingLabelsAnimated

That doesn't work :( rotatingLabelsAnimated is not a valid message to a RTExample ...

Why trying to use Roassal2 instead? Your code will stay the same, but it
will directly use Athens.

Have you tried to use the old Athens packages ? Is it working with them ?

Under Linux I have :

And the problem is still there.

What exactly do you do?
That you made.... :

CairoBackendCache flush.

But I am under Linux x64....

@Vincent: I think at this point you know the most about the issue. Would you like to take charge of it and bring it on the Pharo mailing list?
Yes Vincent. Can you do it? The only thing I can do is forwarding the picture to the pharo mailing list and crying for help

Alexandre
There is a bug opened. A temporary solution is to do :
CairoBackendCache flush

Tell me if the problem is solved from your points of view ?

Because when you use the old Athens packages, this very strange behaviour vanishes ....

The odd font behavior you have shown in the previous emails, seems to happens after some time… I have seen it in the past.

Hi,

I tried to debug a bit more.

First, I noticed that Roassal was using the FreeTypeFont and Trachel the LogicalFont. I now changed Roassal to                               also use the LogicalFont. This did not solve the issue, but it does ease the comparison. (Just ensure that you clean the cached fonts from ROFontOrganizerAthens if you already worked in the same image before loading the new code)
Then, I noticed that even Trachel does not yet quite work: some letters still appear larger than others. However, at least in the case of Trachel, the width of the characters correspond to the size of the rendering (and this seems to still be a problem in Roassal).

See attachments:

<Mail Attachment.png>

<Mail Attachment.png>

The strange thing is that if you debug, it seems that the code is basically the same in both cases. I am stuck. Ideas?
Look at the level of the canvas's creation, maybe the properties are not the same...

For Roassal, I loaded the older packages of Athens-Core and Athens-Cairo :

And I have no problem in font displaying !

In the newer version, they have implemented the text rendering with NativeBoost.

As Roassal2 works fine with the newer version, I don't know if this is a problem with Roassal or with Athens-Cairo.
Maybe you should look at it ?

Cheers,

Vincent

Thanks, Vincent.

I integrated your change in Trachel. It works well now.

Hi,

The following code solve the issue under Roassal2 (Tested under Linux) :


TRLabelShape class>>getFontForSize: aNumber
    ^ LogicalFont familyName: StandardFonts defaultFont familyName pointSize: aNumber

For Roassal, the fonts used are the same that in Roassal2 so I don't think that is the problem.

But it seems that the Athens Font Renderer has been changed (CairoFreetypeFontRenderer) the 4 February (Athens-Cairo-MarcusDenker.62).
This the only thing I see with my knowledges on Roassal. And I don't know how to solve it. Maybe does Alexandre know ?

Cheers,

Vincent

Hi Vincent,

What is the status on this?

At this moment, essentially all visualizations containing text are broken (Roassal, Roassal2, GraphET). This is a show stopper.

Let me know about your progresses with the font problem.
Everything should be treated in Trachel I have the impression.
I have found a solution to fix the bug:

TRLabelShape class>>getFontForSize: aNumber
    ^ LogicalFont familyName: StandardFonts defaultFont familyName pointSize: aNumber

In this, it creates an other font with the good size. Because if you don't do that, you always have the same problem.

"StandardFonts defaultFont familyName" should be enough to get the font to use. Maybe we have to change something else in Roassal2.

No problem to use Roassal 2 instead !

But I have the same issue on the examples.

Which issue?

The font display issue..

  RTDowserExample new coolStuff :

<ghcgceef.png>
That is under Linux. It's not very readable..


And I think there is the same issue with W7
If you want some help, I can. But I need some pointers :)

I have the impression, that the class TRLabelShape has to be improved.
For example, consider the following method:
-=-=-=-=-=-=-=-=-=-=-=-=
TRLabelShape class>>getFontForSize: aNumber
        ^ LogicalFont familyName: 'Arial' pointSize: aNumber
-=-=-=-=-=-=-=-=-=-=-=-=

The font name is hardcoded, which is not a good idea since you may have a different font set on your machine. It would be great to use the installed font, used by Pharo.

That a good idea ! Because under Linux, the Arial font doesn't exists.....



But with this :
LogicalFont familyName: 'Source Sans Pro' pointSize: 12
You have :
<ijdgccca.png>

I will search how to use the system fonts.
By the way, have you tried: RTExample new rotatingLabelsAnimated

That doesn't work :( rotatingLabelsAnimated is not a valid message to a RTExample ...
:-)

Hi!

I have spent a lot of time on trying to understand font, and many bugs are
still there. I would indeed be happy to have help on this...

Why trying to use Roassal2 instead? Your code will stay the same, but it
will directly use Athens.

Hello everyone,

Under the latest version of Moose, I am confronted to some problems of

text displaying with Roassal. The text letters are not in the same font..


A first example :

A second example :

And if I zoom in or out, the text is correctly displayed...

That's strange..

I am on Ubuntu x64 and I have the same issue on W7.
