Base image (in miniwindow) Blend image (mentioned in WindowBlendImage)

The modes on this page operate over all three channels (red, green and blue) rather than individual pixels. In each case a subset of the colours in the blend image is retained. The base layer is overwritten completely, unless you specify an opacity of less than 100%.

Select red mode (51)

Only the red channel is retained.


Select green mode (52)

Only the green channel is retained.


Select blue mode (53)

Only the blue channel is retained.


Discard red mode (54)

The red channel is discarded, the other two channels are retained.


Discard green mode (55)

The green channel is discarded, the other two channels are retained.


Discard blue mode (56)

The blue channel is discarded, the other two channels are retained.


Red to all channels mode (57)

The red channel is copied to all three channels, giving a grey-scale look, that is comprised of the red in the blend image.
