Sets pixel color at coordinates (x,y).
Call Apply to actually upload the changed pixels to the graphics card.
Uploading is an expensive operation, so you'll want to change as many pixels
as possible between Apply
calls.
ARGB32
, RGB24
and Alpha8
texture formats.
For other formats SetPixel
is ignored.
The texture also has to have Read/Write Enabled flag set in the import settings.
