The image package

+ +

+The image package has had a number of +minor changes, rearrangements and renamings. +

+ +

+Most of the color handling code has been moved into its own package, +image/color. +For the elements that moved, a symmetry arises; for instance, +each pixel of an +image.RGBA +is a +color.RGBA. +

+ +

+The old image/ycbcr package has been folded, with some +renamings, into the +image +and +image/color +packages. +

+ +

+The old image.ColorImage type is still in the image +package but has been renamed +image.Uniform, +while image.Tiled +has been renamed +image.Repeated. +

+ +

+This table lists the renamings. +
