nconvert 4.79 segmentation fault when rotating
Posted: Tue Jun 26, 2007 6:47 pm
I noticed image rotations of arbitrary angles result in jagged edges, so I was happy to see the 4.79 release add a "-rotate_flag smooth" option. But I can't get it to work.
This works (with jaggies): nconvert -rotate 9 -o out.jpg orig.jpg
this produces the same result (I guess the smooth flag is not picked up) : nconvert -rotate_flag smooth -rotate 9 -o out.jpg orig.jpg
but anything specified after the "-rotate" param results in a segmentation fault : nconvert -rotate 9 -rotate_flag smooth -o out.jpg orig.jpg
for instance, this command works on ver 4.51, but segmentation faults on 4.79 : nconvert -rotate 9 -crop 0 0 100 100 -o out.jpg orig.jpg
output :
