I'm a newbie to freetype, but I have managed to get my first simple
string rendering routines working on our target platform, using the 8bit
anti alias output, and the following basic algorithm ...
FT_Init_FreeType();
FT_New_Face();
FT_Set_Char_Size();
FT_Load_Char();
draw_bitmap(); /* code to copy glyph bitmap to lcd */
The trouble I now have is when trying to incorporate colour. The basic
glyph bitmap is 8bit gray scale, but I would like to be able to specify
a background and foreground colour.
The anti alias routine (obviously since it's gray scale !!) assumes a
white foreground and black background. Any attempts to incorporate
different colours look terrible (since the AA info is now wrong).
I have Googled for an answer, but only found a reference to using the
FT_Outline_Render() function, but no examples (which has stumped me due
to my being a beginner).
Can someone tell me if this is the function I need to be using (in which
case I'll persevere) ?
If not, is this possible at all ? Where should I be looking ? Does
anyone have any examples ?
This must have been done before, and I hate re-investing the wheel.
Thanks for any help you can give me.
