Equalize modifies an image to ensure that all levels of brightness are equally well represented. This function is very similar to the AutoLevels effect but is designed to modify brightness rather than color levels.

Workings
|
Most images span an entire range of brightness with all levels well represented. However sometimes images are too light or too dark and some levels are overpopulated leaving others underpopulated. The Equalize effect modifies an image so that all levels of brightness are equally well represented within the image.

Example
|
The following example images show the effect of Equalize.
void function() {
using (Doc doc = new Doc()) {
AddImagePage(doc, img2); // original image
doc.Rendering.Save("EffectEqualize1.jpg");
using (ImageLayer layer = AddImagePage(doc, img2)) {
using (EffectOperation effect = new EffectOperation("Equalize")) {
effect.Apply(layer.PixMap);
}
}
doc.Rendering.Save("EffectEqualizeAfter1.jpg");
AddImagePage(doc, img6); // original image
doc.Rendering.Save("EffectEqualize2.jpg");
using (ImageLayer layer = AddImagePage(doc, img6)) {
using (EffectOperation effect = new EffectOperation("Equalize")) {
effect.Apply(layer.PixMap);
}
}
doc.Rendering.Save("EffectEqualizeAfter2.jpg");
}
}
