Description
The imgRGBmerge function merges the Red, Green and Blue channels to recombine a color image.
Examples
In this example, we use the imgRGBmerge function to recombine a color image from its RGB channels (the channel images are named Red, Green and Blue):
- Select Image: Conversion: RGB Merge. This opens the dialog of the X-Function.
- In the X-Function dialog, choose the images for the red, green and blue channels and click OK to close the dialog.
A new image is created. It is the recombined color image.
Input Image

Green channel image
Blue channel image

Algorithm
In Origin, any pixel of a color image is represented by its red, green and blue components. To recombine an image from its red, green and blue channels, we just need to take each component from the color channels and combine them.
