As I tested GrGetScanlineC() is in libgrx20.a (getscl.o)
(at least I have this function in version on my HD). I have used
SaveContextToJpg() to generates frames from output of one my program
for later conversion to MPEG. I expected better quality of MPEG file
I got, but otherwise all worked. Check if Your library have this
function.
