convert options: see 'convert --help'Notes:
- Listing of recognised formats can be get trough
identify -list format - Format of file image can be discovered trough
convert <image> -print "%m\n" null: - Color space of file image can be discovered trough
convert <image> -print "%[colorspace]\n" null: - Size input format is defined by an ImageMagick geometry
- Density input format is defined by an ImageMagick density
- Alpha channel manipulation, trough alpha and background params, is defined by ImageMagick alpha; here some examples
stack_image.sh - Stack image(s)
Usage: stack_image.sh -i input_file[,input_file] -o output_file [options] [convert options]
