Hi, Are you rendering your Cairo results inside a Morphic window? Esteban On Jan 29 2022, at 8:42 am, Stewart Maclean <stewart@xtra.co.nz> wrote:
Hi,
I am working on a proof of concept reimplementation of an application developed in VisualWorks using Cairo and Pango.
When I compare the renderings I see that the VisualWorks has a finer grained resolution.
Initially I thought is was to do with my anti aliasing settings, but upon further investigation I'm wondering if it is because the VisualWorks uses the Quartz backend.
Please see the attached for a comparison - Pharo rendering using Cairo and Pango on the left, VisualWorks using Cairo and Pango on the right. Notice the almost double the number of "pixels".
I've tried switching to using the Quartz Athens surface, but nothing gets displayed.
I would appreciate it if someone can confirm that my analysis is correct, and that in order to get the better results I would need to hook up to the Quartz backend?
Thanks,
Stewart
