TSVGIconImage - something wrong with colors? #248

Closed kazuser closed 1 year ago

kazuser commented 1 year ago

Could you please explain, what's going on with white color?

It looks ok in design-time (in preview): image

but not in run-time: image

Test project: Project1.zip

p.s. Yep, I know it's funny but I need 100,00% accuracy, not 99,999% 🥲

Have you tried with a white "box"? It could be due to the antialiasing of the X which being very fine the stroke creates reduces the color slightly. The only difference I see is the background color: the run-time one is darker.

Must be due the antialiasing. Can it be disabled for testing?

You beat me to it by a few seconds @carloBarazzetta :)

carloBarazzetta commented 1 year ago

No, I've no control on the engine that draw the image: are you using Image32?

kazuser commented 1 year ago

Ok, how to disable "antialiasing"? I see "Disable Interpolation" only (and it doesn't help).

kazuser commented 1 year ago

I using with defaults settings.

Could you please try my sample (is in a zip-file in first message) and confirm/refute wrong color?

have no control over the antialiasing effect applied by the SVG-Engine being used. You can test with a circle instead of an 'X' so that the center pixel can't be affected by antialiasing.
