Are Equal (Image) (vuo.image.areEqual)

Outputs true if all images have the same dimensions, and if their contents are close to equal.

If there are no images, outputs true.

Tolerance is the maximum amount by which any two component values can differ to still be considered equal. For example, in RGBA images, all red channels must be within Tolerance, and likewise for all green, blue, and alpha channels.

When comparing a 1-component image to a 4-component image, the 1-component image is treated as grayscale and opaque — i.e., for the images to be considered equal, the 4-component image must be grayscale and opaque within the specified Tolerance.

When comparing a 3-component image (no alpha) to a 4-component image (with alpha), the 3-component image’s alpha is assumed to be 100%, so for the images to be considered equal, the 4-component image’s alpha needs to be within Tolerance of 100%.
