Hi,
I'm trying to learn how to use directfb to write a statically linked
program (using the example from the examples image.c tarball as a base)
that among other things will be displaying a variety of graphics
but the screen is rotated in the device CCW 90 degrees so just blitting
the image using the device information puts the graphic in the middle of
the screen
and rotated. i've tried using --dfb:layer-rotate=90 but as i'm not sure
whatelse i need to do in my app to get that working it does nothing and
if i manually
rotate the image using gimp and try loading that i get a floating point
error.
when i start the program on the device i get two Unimplimented errors
/mnt/sd0 # ./image.1 --dfb:layer-rotate=90

which I don't get when i run the app without the --dfb:layer-rotate=90
so i assume i'm linking incorrectly or missing something.
