output = ColorImage

  

Specifies a data structure into which the output is written. This can be used to avoid allocating memory. The height, width, and order 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 default is NULL.

Description

• 

The ToRGB command converts grayscale, RGB, and RGBA images to RGB images.  This is useful if a grayscale image is to be combined in some way with an RGB image.

• 

The img parameter is the image to convert.

• 

If img is of type GrayImage, a new image is created with each color layer identical to the input image.

• 

If img is of type ColorImage, the image is returned.

• 

If img is of type ColorAImage, a new image is created with each color layer identical to the corresponding layer of the input (the alpha layer is omitted).
