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
