: Using nano-X under AVR32 the Freetype2 support renders font colors with
: red and blue colors reversed mixed up (at 24bit color depth).
:
: IIRC the Freetype library deliver a greyscaled bitmapped image of the
: character to be drawn (glyph image?), which is then transformed into the
: color requested via nano-X.
:
: Can someone please point me where this greyscale to color transformation
: takes place?
The FB2 subdriver uses the psd->drawarea entry point,
which may not be fully configured for your system. The
drawarea entry point is a replacement for blit, as it
was contributed, but not fully integrated in every driver.
Since you're running 24bpp, the driver file src/drivers/fblin24.c
will be used. Compare the drawarea implementation with
the fblin32.c and fblin16.c versions. There may be some
byte swapping or word orientation issues also.
