Description
The invert plugin and, I believe, any other that uses imagej.core.plugins.assign.InplaceUnaryTransform, will only update the first two planes of a color image. To reproduce:
File / Open Samples / Clown
Edit / Invert [IJ2]
Image / Color / Split Channels.
Two of the channels are clearly inverted and the third is not. The problem is in InplaceUnaryTransform.setOriginAndSpan which records the position of the last pixel in each dimension, rather than the length of the dimension (span[i] = dims[i] - 1). net.imglib.ops.image.ImageAssignment.buildRegion then creates offsets pOffsets[i] = spn[i] - 1. The resulting region will be shortened by 1 in every dimension, most notably the channel dimension.
