Selecting Images for Color Correction and Filtration

Selecting Images for Color Correction and Filtration

The color filtration and color correction tools can be applied to a group of color raster images. The colour filter commands work on images that have a clipping boundary. Restrict a filtration area for any image using this feature by specifying its clipping boundary.
 For information on the use of clipping boundary see Cropping.
The colour filters are not applicable to greyscale (grey-level) images. Nevertheless these can be applied to such images after having converted them to colour. Use the Convert to RGB command from the Image menu.
