The Combine command combines three channels of color information into a single composite image.

Red/H/Y channel

Choose the image which will represent this color channel, and choose whether to use the Gray, Red, Green, or Blue values from the image.

For the RGB color space, this image will represent the Red channel; for HSL color space, this image will represent the Hue channel; and for YUV color this image will represent the Y channel.

Green/S/U channel

Choose which image will represent this color channel, and which color values from the source image that you want to use.

For the RGB color space, this image will represent the Green channel; for HSL color space, this image will represent the Saturation channel; and for YUV color this image will represent the U channel.

Blue/L/V channel

Choose which image will represent this color channel, and which color values from the source image that you want to use.

For the RGB color space, this image will represent the Blue channel; for HSL color space, this image will represent the Luminance channel; and for YUV color this image will represent the V channel.

Alpha Channel Source

Choose which image, if any, you want to use to represent the transparency values in the combined image, and select the color channel to use from the source image.

Color Space

Choose which color representation method should be used to combine the channels: RGB, HSL, or YUV.

Source images for each channel must already be open in MagicTracer.

In the dialog box shown above, the RGB color space has been selected. The Red channel for the combined image will be taken from the grayscale values of “Hue Channel 2 from mt-logo.jpg.” Similarly the Green channel is represented by “Saturation Channel 2 from mt-logo.jpg,” also using grayscale, and the Blue channel is represented by the grayscale values of “Lightness Channel 2 from mt-logo.jpg.” No alpha channel image is supplied, so all pixels will be be at full opacity.

It can sometimes be useful to split an image into channels using one color space, then recombine those channels using another color space, perhaps in different orders.

The two images below are an original RGB image, split into HSL channels, then with the HSL channels recombined as RGB channels as indicated in the dialog box shown above:
