Team,
I am writing an OS-less embedded test application for ARM and use a 320 by
240 screen. Pixels in 16bit RGB.
Just aim for having B/W debug text output on screen for the moment.
Loading TTF glyphs work after selecting charmap and characters are
identified giving correct glyph indexes back.
However, the call " error = FT_Render_Glyph( face->glyph,
ft_render_mode_mono ); " crashes and it seems
no renderer is found, thus there is no result in 'face->glyph->bitmap' at
all. I want results....
Can my config be wrong? See contents of 'ftmodule.h' below.
Other pitfalls?
