So, I added support for retina on the Macbook Pro. Text looks great.

I made icons double size and draw them at half size on canvas. This makes them look sharp on retina and fine on normal Macs with no conditional drawing needed. I use code like this in the Canvas.paint event:


However, when running on Windows, my half size icons have unacceptable artifacts from the halving. I assume the Windows graphics renderer is not as spiffy.

Do I need to create 2 versions of all my icons or is there some trick I've missed?

Works/looks just fine for me on Windows 7. Maybe set App.UseGDIPlus to True.

Thanks. Alas, same dodgy result with App.UseGDIPlus

Same for me for Win 7 and Win XP.

Making the image even pixel dimensions helps but some images, like those with repeating straight lines, just don't scale.

I believe this will be your best best. I believe that even Apple recommends having 2 sizes of images, 1 for regular and 1 for Retina Display. Scaling doesn't work in all cases.

Thanks Bob.

Anyone have suggestions on the best way to manage images?

Are these images masked? If so, do non-masked images scale without aliasing?

I'm experiencing unacceptable aliasing when scaling masked images under Mac OS X Cocoa builds. However, if I pre-composite to a non-masked picture and scale that instead, I don't have this issue.

Edit: It seems Real Studio isn't setting the interpolation correctly on Cocoa. The solution is discussed at viewtopic.php?f=7&t=47968

They're not masked. I'd hate to have to go back to masking my images.
