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):

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 !
