screenshots between OS's
This question is not specific to TestComplete, but I thought someone on here might know. Our application has a WPF user interface. We have been running TestComplete on Windows XP and Windows Vista, and we have a large number of reference screenshots that are used as region checkpoints. In order to make XP and Vista match across all our hardware, I had to disable all forms of antialiasing, including adding registry keys to disable WPF antialiasing and turning off hardware antialiasing through the display driver.
Today I got a Windows 7 machine to set up as another test machine. Despite turning off ClearType, grayscale antialiasing, all the display driver options, and WPF antialiasing in the registry, my screenshots do not match under Windows 7. By looking at the image diffs I am 100% sure the difference is antialising, as it is only rendered text that is mismatched. Does anyone have any ideas?
