IM 6.7.6.4 Q16 Mac OSX Snow Leopard.

Seems like my script, 3Dbox, is failing with a segmentation fault. I have not tested it in a while and so am not sure when this started.

The following works with images as jpg and gif.

img1="mandril.jpg"
proc1="-matte +distort Perspective"
s1="0,0 0,24.2195 127,0 99.3534,-49.6767 127,127 81.927,40.9635 0,127 0,112.896"

img2="logo3.gif"
proc2="-matte +distort Perspective"
s2="0,0 -99.3534,-49.6767 127,0 0,24.2195 127,127 0,112.896 0,127 -81.927,40.9635"

img3="zelda3.jpg"
proc3="-matte +distort Perspective"
s3="0,0 -99.3534,-49.6767 127,0 0,-104.25 127,127 99.3534,-49.6767 0,127 0,24.2195"

convert -virtual-pixel transparent -mattecolor none \
\( $img1 $proc1 "$s1" \) \
\( $img2 $proc2 "$s2" \) \
\( $img3 $proc3 "$s3" \) \
-background black -layers merge +repage \
show:


However, this fails if the images are converted to .mpc first.

convert mandril.jpg 1tmp1.mpc
img1="1tmp1.mpc"
proc1="-matte +distort Perspective"
s1="0,0 0,24.2195 127,0 99.3534,-49.6767 127,127 81.927,40.9635 0,127 0,112.896"

convert logo3.gif 1tmp2.mpc
img2="1tmp2.mpc"
proc2="-matte +distort Perspective"
s2="0,0 -99.3534,-49.6767 127,0 0,24.2195 127,127 0,112.896 0,127 -81.927,40.9635"

Segmentation fault


Why is this happening? Am I missing something or mistyped something?

We can reproduce the problem you reported and have a patch. Look for it in ImageMagick 6.7.6-5 Beta within a day or two. Thanks,
