I'm currently running convert.exe 3 times to generate 3 different crops from 1 image:

convert.exe -resize 800 -unsharp 0x0.75+0.75+0.008 -gravity center -crop 800x533+0+0 +repage OrigFile OutputFile1
convert.exe -resize 800 -unsharp 0x0.75+0.75+0.008 -gravity North -crop 800x533+0+0 +repage OrigFile OutputFile2
convert.exe -resize 800 -unsharp 0x0.75+0.75+0.008 -gravity South -crop 800x533+0+0 +repage OrigFile OutputFile3

These all work perfectly well, though the problem is I have to run convert.exe 3 times for every image. How would I launch it once and have it do all 3 crops at one go? The only difference is the -gravity.

I am on Windows 7, and I am launching convert.exe from another program. I can either use either the command-line or read commands from a file, no prob. Input and output files are all jpg. Would appreciate the correct syntax to "stack" these commands.

TIA

The input file, OrigFile, should be placed before all those options, not after. This not only runs convert 3 times, but reads the input 3 times, resizes 3 times and unsharps 3 times.

As one command, something like this:

Code: Select all

convert.exe ^
  OrigFile ^
  -resize 800 -unsharp 0x0.75+0.75+0.008 ^
  ( +clone -gravity center -crop 800x533+0+0 +repage -write OutputFile1 +delete ) ^
  ( +clone -gravity North -crop 800x533+0+0 +repage -write OutputFile2 +delete ) ^
  -gravity South -crop 800x533+0+0 +repage OutputFile3

Hi snibgo, that works exactly as I wanted. Thanks so much!
