Roassal Issue with Text Displaying
 
|
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.

Hi, I got even stranger artifacts on Windows 7: If I try this: view shape label text: #asString. view nodes: #(ABcdE FGhIJKlm). I get this:  Could someone look into this? Doru On Wed, Feb 12, 2014 at 10:55 AM, Vincent Blondeau <[hidden email]> wrote:

Hi Vincent, Do you mean to say that you have tried Roassal2 and you got the same problems on Ubuntu or Win7? I just tried my example code on Mac with Roassal1 and it works as expected.
view shape label text: #asString. view nodes: #(ABcdE FGhIJKlm). So, the font problems seem to be platform specific. I will try with Roassal2 as well.

The font display issue..No problem to use Roassal 2 instead ! But I have the same issue on the examples.Which issue? RTDowserExample new coolStuff :  That is under Linux. It's not very readable. And I think there is the same issue with W7 That a good idea ! Because under Linux, the Arial font doesn't exists...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. But with this : LogicalFont familyName: 'Source Sans Pro' pointSize: 12 You have :  I will search how to use the system fonts. That doesn't work :( rotatingLabelsAnimated is not a valid message to a RTExample ...By the way, have you tried: RTExample new rotatingLabelsAnimated :-) AlexandreCheers, Vincent -----Message d'origine----- De : [hidden email] [[hidden email]] De la part de Alexandre Bergel Envoyé : mercredi 12 février 2014 15:50 À : Moose-related development Objet : [Moose-dev] Re: Roassal Issue with Text Displaying 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, 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? Doru On Tue, Feb 18, 2014 at 1:48 PM, Vincent Blondeau <[hidden email]> wrote:

Exactly, that is my current hypothesis, but I do not know exactly where to look. Doru On Wed, Feb 19, 2014 at 9:58 AM, Vincent Blondeau <[hidden email]> wrote:

Hi!
I’ve just tried in a fresh up-to-date moose image:   The odd font behavior you have shown in the previous emails, seems to happens after some time… I have seen it in the past.
