ImageTools[SetLayer] - insert a layer into a multi-layer image
Calling Sequence
SetLayer( img, img_layer, layer, opts )
Parameters
img
-
ColorImage or ColorAImage; input image
img_layer
GrayImage; input layer
layer
1,2,3,4; layer index
opts
(optional) equation(s) of the form option = value; specify options for the SetLayer command
Description
The SetLayer command replaces a single layer within a multi-layer image.
The img parameter is the input image and must be of type ColorImage or ColorAImage.
The img_layer parameter is the image that is inserted into img. It must be of type GrayImage.
The layer parameter is the index of the layer to insert. It is an integer from 1 to 3 for a ColorImage, or from 1 to 4 for a ColorAImage.
Options
inplace = truefalse
Specifies whether the operation is performed in-place. This can be used to avoid allocating memory. The default is false.
output = Image
Specifies a data structure into which the output is written. This can be used to avoid allocating memory. The size and number of layers must match that of the input. The dimensions of the output image are adjusted so that the row and column indices match the input. The output option overrides the inplace option. The default is NULL.
Examples
Create a blank (black) color image and three grayscale images.
Insert, separately, the grayscale images into the blank color image, as the red, green, and blue layers.
Insert all three grayscale images into the blank color image.
View the results.
