Yes, James and Werner do:
srcImage = member(11).image
member(12).image = image(srcImage.width, srcImage.height, 1)
member(12).image.fill(srcImage.rect, rgb(0, 0, 0))
inkParams = [#ink:#backgroundTransparent, #color: rgb(255, 255, 255)]
-- All white pixels are not copied over.
-- The rest are converted to white pixels
member(12).image.copyPixels (srcImage, srcImage.rect,
srcImage.rect, inkParams)
member(12).image.copyPixels (member(12).image, srcImage.rect,
srcImage.rect, [#ink:#notCopy])
member(12).regpoint = member(11).regpoint
