Converting Images
Use the Convert group commands on the Adjust ribbon to transform an image to another color model, to extract a specific color channel from a color image, or to merge an active, 8-bit gray scale image into a True Color image. You might do this to perform editing or analysis upon the image in another model or to save the image data in a different model for use with an external program.
To convert an image:
Select the Destination image type from the drop-down list. For example, if you want the resulting image to be a single channel 12bpp image, select "Mono 12bpp".
Click Apply.
You are presented with an options dialog box.
Select the type of conversion to perform: Scale, Best Fit, Direct Copy, or Custom.
Your image is automatically converted to the new model. Once you have set the conversion options the way that you want them, you can click the Apply button in the Convert group to convert the active image using the current settings without making furrther changes.
