You need to use the latest Win32 VM - 3.9.2

The required modifications to BitBltSimulation are in a changeset that I have
attached.

I installed it on my MacBook, but I can't see any difference.

How to active it?

Cheers.

It activates itself when installed.

Do you see any new fonts when you set, for example, the List font from the
World, Appearance, System fonts... menu?
If not, then perhaps you are missng the FT2Plugin. Evaluate this in a
workspace...
    FT2Version current
it should answer '2.2.1'. If it answers nil, then the plugin is missing.

Cheers,
Andy

Uhmm, I get 2.2.1. but I don't see more fonts.

Probably I need glasses.

ok.

Try evaluating ...
    TextConstants keys asSortedCollection
you should see lots of font names that you recognize.

The Mac OS X font paths are currently hardcoded as
    '/System/Library/Fonts'
    '/Library/Fonts'
Check those locations on your disk, to make sure that they exist, and contain
some fonts.

Also, to see which font files have been found on your system, evaluate this...
    FreeTypeFontProvider current instVarNamed: 'fileInfos'
you should get a set of file paths, together with the name and style of the font
contained in each.

Cheers,
Andy

Speaking of which, I do see more fonts but not all those I have
installed. I didn't check but probably the plugin doesn't look in all
paths, or it only detects TTF fonts and not Type 1 or OpenType ones ?

I'm on Mac and the plugin does work most of the time, I get very nice
font display, except I think when the changed BitBlt is needed (with
colored fonts probably) and the text morph becomes a big red rectangle
:)

Also the contents of the menu are not always the same, not in the same
order, or paginated differently (in the appearance > system fonts
menus).

Finally the point sizes are not consistent with the ones in Cocoa
apps. An 8pt font in Squeak looks like its 10pt version in Cocoa.

Can you give an example of a font that is missing?
If you could send the font file to me privately, that would be great.

It should work ok without the BitBltPlugin. There is a bug somewhere there. Do
you get a debugger at all? I am wondering what the error is that has caused the
TextMorph to stop drawing.

They should be in alphabetical order.
And when you change a system font it should show you the currently selected font
in blue. So it will 'jump' to the page that contains that font.
If you are seeing something different, then a screenshot would be helpful.
Thanks.

I believe that Mac uses 72 dpi, whereas the default in Squeak is 96dpi.
Try changing Squeak's setting to 72 and see if the font sizes then match.
You can do this by evaluating...
    TextStyle pixelsPerInch: 72.0

Ok, based on this change set I built a BitBltPlugin for Mac Carbon VMs.

Find it via my idisk or FTP.

http://www.smallltalkconsulting.com/squeak.html

in the experimental folder

BitBltPlugin.v1.0.0b1.FreeTypePlus.bundle.zip


I know it gets loaded, but I don't know if it works since I'm not  
sure what I'm looking to test for.
However I suspect some eager  macintosh users will give me feeback  
before lunch today.

To install, unzip and put the *.bundle in the Resources beside the  
FT2Plugin


About the FT2PLugin.bundle.  Macintosh users should ensure they have  
the 2.2.2c51 or later FT2Plugin.
2.2.2 resolves some crash issues that are in the 2.2.1 freetype code,  
and loads all the freetype fonts on your macintosh, 2.2.1 did not.
2.2.2 is found in VMs I think at 3.8.16 or higher.   Also found on my  
idisk in the Sophie Folder

For those who wish to check that it is working ok...

A quick check is to evaluate...
    FreeTypeSettings current clearBitBltSubPixelAvailable;
bitBltSubPixelAvailable
.it should answer true.

Another check is to change the FreeType GlyphContrast Preference to 99.
If all the glyphs go much darker, then the plugin is applying the contrast
setting correctly.
(set it back to the default of 50 when you are done)

The last check is to install the FreeType Plus (sub-pixel anti-aliasing) package
from SqueakMap.
Then use a magnifier morph to magnify some text;  the glyphs should have colour
fringes around them.

Cheers,
Andy

It looks like it only sees fonts from /Library/Fonts (the machine-wide
font directory) and not fonts I installed just for me in
$HOME/Library/Fonts (I know, I know, I'm the only user on this machine
:D )

It seems it doesn't like PS type1 and OpenType fonts. Maybe this is a
limitation of freetype ? For instance, Audimat, freely available at
http://www.smeltery.net/ (sorry, crappy site, no direct URL)

The primitive fails in #copyBitsColor:alpha:gammaTable:ungammaTable:
        <primitive: 'primitiveCopyBits' module: 'BitBltPlugin'>
Debug log attached.

OK, it does all this, but it puts the selected font on top of the
page, so the page jumps appear at different places depending on which
font is selected.

They do too.
Can we have a universe package for this?

hmmm.

*runs around*    WHEEEE NICE FONTS RULE!!!!

Yes. The user fonts folder is excluded. (This will require some FFI calls, or a
plugin function, to get the user fonts location from the OS). If you want to get
access to these fonts, you could edit
FreeTypeFontProvider>>getMacOSXFontFolderPaths so that it includes your user
fonts path, then save, exit, and restart the image.

The AUdimat otf fonts load ok on Windows.
Did you see John's comment about using the 2.2.2c51 or later FT2Plugin?
I wonder if that will solve the problem.

Thanks. The log shows that it is failing with a zero width sourceForm....
     Receiver's instance variables:
          destForm:  DisplayScreen(1021x745x32)
          sourceForm:  Form(0x1x32)
This is when drawing the strikethrough line. So it should be easy to fix.

Yes. It's pretty horrid :)
All the menus really need re-working to provide nice scrolling lists.

Cheers,
Andy

In all of this I'm not sure if people noticed another important  
change we made in Sophie.

That was changing emphasis from a magic number to an object.

Then you could ask

isBold
        ^self emphasis includesEmphasis: SophieFontEmphasisEncoder bold


The reason for this was to handle things like 'Light' ,Condensed,  
Medium, Demibold, or ExtraBold
Also to get rid of magic numbers, which btw were not say in a 3.8  
image actually correctly handled in *all*
the places where code was looking for magic emphasis numbering.

I have John's latest (3.8.17b4) VM with this version of ft2 I think

cool :)

Hmm, I'd say "to not need to scroll nor page in the first place" :)

Yes, I noticed that. And I remember you mentioning it to me in the past.
It is a good idea.
I have stuck with the existing magic number scheme mainly because the thought of
identifying, and changing, all the existing places where these magic numbers are
used seemed quite daunting.

This is good for font substitution and document portability.
Currently, I simply treat these 'unusual' weights as being distinct font
families, and don't do anything clever about matching missing fonts to the best
available substitute.

(On a similar theme, there was a very interesting article mentioned on a
FreeType newsgroup about how font names, families, and groupings are determined
on Windows. I don't know if you have come across it before, but you might find
it interesting...

ok. I'll try with the same font on Linux, and see what happens there.

:)
Do you have any ideas on how that could be done?
If, for instance, you had 999 fonts?

A fisheye, everything tiny, until you hover over it view?
Or typing the font name to bring up matches?

I'm curious.

Andy

I recall (it was years ago now) we altered things so that if you  
asked for the magic emphasis number you
would get a number back for backwards compatibility which was  
calculated from the font's emphasis object,
otherwise all the Sophie code worked with another accessor that gave  
back the emphasis object to work with.

For a year or so we ran with an assert to ensure no over eager  
developer stuffed a magic emphasis number into the emphasis object slot.
