Hello!

I use Canvas.TextOut to draw some text on bitmap.
For example, I draw red text to white background.
Then I check RGB values of result bitmap.
So, I have under Win32:
Code: [Select]a lot of 255.255.255 (white)
a few 255.0.0 (red)All is ok here.
But under Linux/Gtk2:
Code: [Select]a lot of 255.255.255 (ok, white)
255.40.18
255.187.227
255.42.136 and soon.
I try to change antialiasing and some other text options, but I have
the same result.
One man (Paul Ishenin)  on freepascal.ru forum said that libpango is
used to set font antialiasing at gtk2 and I cannot turn antialiasing
off.
But, I have NOT this problem with Gtk2 under Win32.

any ideas?

Try using the Qt interface for Linux
