Changing antialias for different background colors

[aiotech]

Hello guys,

I designed a set of icons to be used on buttons for Android apps. They are drawn in black and antialiased for a white background so the pixels near the edges are of different types of gray. Now I would like to use the same icons on a light green background but they do not look very well. Is possible to "correct" in some way the antialias effect for the new background color without redesign the icons? Thanks,

Massimo

Why are you not antialiasing using alpha instead of shades of gray?

Mmmm... I think the honest answer is because normally I modify old icons made in this way and because also fonts are antialiased in this way. But I would happy to learn a better tecnique if you point me somewhere to learn.

I know nothing about Android icons.  You should ask on a forum dedicated to Android development.

Due to the rise of HiDPI on Android many years ago, Google has long recommended against using bitmap/raster images for your UI.

 

You should convert your icons to vector images.
