Transform Operations
Colour
Operations used to adjust the colour of the image.
- RandomThreshold
Changes the value of individual pixels based on the intensity of each pixel compared to a random threshold. The result is a low-contrast, two color image. - FloodFill
Flood-fill texture across pixels that match the color of the target pixel and are neighbors of the target pixel. Uses current fuzz setting when determining color match. - Gamma
Gamma correct image. - Colorize
Colorize image with the specified color, using specified percent alpha for red, green, and blue quantums" - Segment
Segment (coalesce similar image components) by analyzing the histograms of the color components and identifying units that are homogeneous with the fuzzy c-means technique. Also uses QuantizeColorSpace and Verbose image attributes. - Threshold
Threshold image. - Transparent
Add alpha channel to image, setting pixels matching color to transparent. - Contrast
Contrast image (enhance intensity differences in image) - CycleColormap
Displaces an image's colormap by a given number of positions. - Equalize
Applies a histogram equalization to the image. - Evaluate
Apply an arithmetic or bitwise operator to the image pixel quantums. - HaldClut
Apply a color lookup table (Hald CLUT) to the image. - Level
Adjust the levels of the image by scaling the colors falling between specified white and black points to the full available quantum range. - Modulate
Modulate percent hue, saturation, and brightness of an image. - Negate
Negate colors in image. - Normalize
Normalize image (increase contrast by normalizing the pixel values to span the full range of color values) - Opaque

Crop image (subregion of original image) - ChopHorizontal
Chop image (remove horizontal subregion of image) - ChopVertical
Chop image (remove horizontal subregion of image)
Image Format

Remove a named colour profile from the image. - RePage
Resets the page property of this image. - Strip
Strips an image of all profiles and comments. - ChromaBluePrimary
Sets the chromaticity blue primary point. - ChromaGreenPrimary
Sets the chromaticity green primary point. - ChromaRedPrimary
Sets the chromaticity red primary point. - ChromaWhitePrimary
Sets the chromaticity white primary point.
