## 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):

1. Select Image: Conversion: RGB Merge. This opens the dialog of the X-Function.
2. 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

 Red channel image Green channel image Blue channel image

Output 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.
