Welcome. I'd just like to point out a couple of resources for the rendering testing framework.
The ghostscript/ghostpdl source distribution has a little program called bmpcmp under toolbin/bmpcmp.c . It is used by the ghostscript people for comparing small bitmap differences and have various configuration parameters to ignore 1-pixel differences,etc. for their regression testing. (that includes fonts embedded or not embedded in ps/pdf files, so it sorts of been testing changes in freetype too) I have just had a whole bunch of example *-cairo.py programs merged into https://github.com/rougier/freetype-py/tree/master/examples I wrote most of the freetype-py matplot-based drawing examples to draw with cairo instead. You could using python to grab freetype bitmap that way. This is the sort of things one can do: https://github.com/rougier/freetype-py/issues/58#issuecomment-298802012 yes, same as ftgrid/ftview; and I used ftgrid for reference. _______________________________________________ Freetype-devel mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/freetype-devel
