while you are at it, you could try the processing of djvu from the tools in
http://dftuz.unizar.es/~rivero/lbdjvu.tgz
Also, attached you can see xclock running in the librie using the xvfb trick. It relies on xwdtopnm, included in the above tgz.
It was running over a 600x800x4 screen using a loop
./xwdtopnm /tmp/Xvfb_screen0 | ./pnmdepth 255 | tail +4 > /tmp/rawscreen
./pgm4biARM /tmp/rawscreen | ./putpic.arm
the depth depends on the framebuffer driver most probably it is different in the Reader.
Of course in a separate process, I run
Xvfb :1 -screen 0 600x800x8 -fbdir /tmp
and still in other
export DISPLAY=":1"
xclock
I am sorry I can not find Xvfb. It was compiled from the xorg sources for a X11R6 version.
