Sorry for the false alarm.
However, it is odd that this only happens when I run the script using mpc and it does not happen with miff: or png.

IM 6.4.8-1 Q16 Mac OSX Tiger
I was given a high resolution (3kx2k) image from a digital camera which I then resized to the following:
P1040409c.jpg
I then processed it with my saturation script, the core of which is the following using no change in saturation (value=1).
dir="."
tmpA="$dir/saturation_$$.mpc"
tmpB="$dir/saturation_$$.cache"
tmp0="$dir/saturation_0_$$.png"
tmp1="$dir/saturation_1_$$.png"
tmp2="$dir/saturation_2_$$.png"
infile="P1040409c.jpg"
outfile="P1040409c_sat1.jpg"
value=1.0
if convert -quiet -regard-warnings "$infile" +repage "$tmpA"
then
convert $tmpA -colorspace HSL -channel R -separate $tmp0
convert $tmpA -colorspace HSL -channel G -separate $tmp1
convert $tmpA -colorspace HSL -channel B -separate $tmp2
convert $tmp0 -colorspace HSL \
$tmp0 -compose CopyRed -composite \
\( $tmp1 -evaluate multiply $value \) -compose CopyGreen -composite \
$tmp2 -compose CopyBlue -composite \
-colorspace RGB $outfile
else
errMsg "--- FILE $infile DOES NOT EXIST OR IS NOT AN ORDINARY FILE, NOT READABLE OR HAS ZERO SIZE ---"
fi
The result P1040409c_sat1.jpg looks as follows, scrunched vertically.
If I add -strip to remove the EXIF data. The result looks normal. Also if I use .miff or .png for $tmpA, the result looks normal even without the -strip. tmp0, tmp1 and tmp2 look fine, so it appears to be happening at the last composite stage before the -colorspace RGB $outfile (as I inserted a -write there and that file was scrunched).
Is this supposed to happen? If so, what line in the EXIF data is causing this.
