	6.2.64. OOF.Image.Modify Commands

Name

OOF.Image.Modify.Normalize — Enhance contrast by normalizing the image.

Synopsis

OOF.Image.Modify.Normalize(image)

Details

Parent Menu: OOF.Image.Modify
Callback: function doImageMod in module ooflib.image.imagemodifier
Parameters:

image

Type: The path to an existing Image object.

Description

Scale and shift the red, green, and blue pixel components so that the Image uses the full range of values (zero to one) for each component. This increases the contrast in the Image. Equalize often does a better job than Normalize, especially if an Image contains just a few very dark or very light pixels.

This routine comes from the ImageMagick library.
