Flags

If only a width, or only a height is provided the missing field will be calculated to preserve the aspect ratio of the images.

Flag	Type	Description
w	Uint	Width to resize both images to
h	Uint	Height to resize both images to
m	String	Mask matrix to use for masking images. (ex) [[1, 1],[1,0]] will create a checkerboard pattern
r1	String	Colour range for the first image (default: "0-240")
r2	String	Colour range for the second image (default: "240-255)
g	Uint	gAMA value (default: 2300). The gAMA value is multiplied by 100,000. So a gAMA of 0.023 would be 2,300
o	String	Path of the output image (default: "output.png")
