String artifact in Athens canvas

Hello,

I am experiencing string artifact in athens canvas. It was not there
with pure morphic canvas and the same font. See screen shot

Thanks

It looks like this is related to the font information.
could you show the same situation with different fonts?

I got this problem in built image for production using a specific font.
In my devel, environment with other I don't have this problem.
Now in previous release of DrGeo I was using this same specific font and
the problem was not there.
I just ask to see if other have simimilar problems. I need to check
further, but I am just exhausted for now.

In this built image, I tried with different font, same problem.
Then I try those font on my dev environment and the problem does not
show up.
The rendering is really strange, see screenshot: letter seems to have
different size, string morph extent is strange.
I tested the built image with my dev. VM, same problem. Looks like
related to my build process, did I removed too much package ?

I remove thoses ones:

"Package not removed from ImageCleaner we want to remove"
        (MCPackage named: 'HelpSystem-Core') unload.
        (MCPackage named: 'ProfStef-Core') unload.
        (MCPackage named: 'ReleaseTests') unload.
        (MCPackage named: 'Versionner-Tests-Core-Commands') unload.
        (MCPackage named: 'Versionner-Tests-Core-DependenciesModel') unload.
        (MCPackage named: 'Versionner-Tests-Core-Model') unload.
        (MCPackage named: 'Versionner-Tests-Resources') unload.
        (MCPackage named: 'Polymorph-Tools-Diff') unload.
        "Metacello"
        (MCPackage named: 'Metacello') unload.
        (MCPackage named: 'Metacello-FileTree') unload.
        (MCPackage named: 'Metacello-GitHub') unload.
        (MCPackage named: 'Metacello-PharoCommonPlatform') unload.
        (MCPackage named: 'Metacello-Platform.pharo30') unload.
        (MCPackage named: 'Metacello-Reference') unload.
        "SUnit"
        (MCPackage named: 'SUnit-UITesting') unload.
        (MCPackage named: 'SUnit-Utilities') unload.
        (MCPackage named: 'SUnit-UI') unload.
        (MCPackage named: 'SUnit-Core') unload.
        "KeyChain"
        (MCPackage named: 'KeyChain') unload.
        "Network"
        (MCPackage named: 'Network-Mail') unload.
        (MCPackage named: 'Network-RFC822') unload.
        (MCPackage named: 'Network-UUID') unload.
        (MCPackage named: 'Network-Url') unload.
        (MCPackage named: 'Zodiac-Extra') unload.
        (MCPackage named: 'Zodiac-Core') unload.
        (MCPackage named: 'Zinc-Zodiac') unload.
        (MCPackage named: 'Zinc-FileSystem') unload.
        (MCPackage named: 'Zinc-HTTP') unload.
        (MCPackage named: 'Zinc-Ressource-Meta-FileSystem') unload.
        (MCPackage named: 'Zinc-System-Support') unload.
        "Settings"
        (MCPackage named: 'Settings-Compiler') unload.
        (MCPackage named: 'Settings-Display') unload.
        (MCPackage named: 'Settings-FreeType') unload.
        (MCPackage named: 'Settings-Graphics') unload.
        (MCPackage named: 'Settings-Kernel') unload.
        (MCPackage named: 'Settings-Monticello') unload.
        (MCPackage named: 'Settings-Network') unload.
        (MCPackage named: 'Settings-Polymorph') unload.
        (MCPackage named: 'Settings-System') unload.
        (MCPackage named: 'Settings-Tools') unload.
       
        (MCPackage named: 'Komiter') unload.


I will try to keep the freetype settings, but it does not make sense.

Ok found some info on this bugs, thanks.

Sadly the workaround will be difficult for DrGeo, because I need
dedicated unicode fonts for both the DrGeo widgets (menu, toolbar, tabs,
dialog) and for the canvas to show messages in locale languages.

Thanks

But this other workaround worked for me (at lease until now):

drawOnAthensCanvas: aCanvas
"Work around for the conflicting size font problem"
        aCanvas pathTransform restoreAfter: [
        aCanvas pathTransform scaleBy: 1.00001.
                "draw text here"
                super drawOnAthensCanvas: aCanvas].

Thanks
