Hi,
Could you please comment on this issue, if you are currently working on the Windows-like implementation of the I-beam cursor (cursor for text selection) in the graphical interface?
In Windows, the I-beam cursor, change color based on the background. So, most of the time it's black, but
Most desktop CRTCs support a XOR key in their ROP, since it was
required by Windows for such a long time. I don't think Linux has
support for that in KMS, nor for similar things like alpha keying as
well. Perhaps we'll get it as a plane property at some point.
I don't know of any mobile/embedded
That's xor of the color bits. The blue/red is due to xor'ing with the
subpixel antialiasing. It is more obvious if you put the cursor over a
solid colored area where you will see strange colors.
It cannot be achieved with Porter-Duff combinations. I am not sure if
OpenGL or DirectX supports
