Value	Description
EyeShadeDark	Dark eye shading.
EyeShadeLight	Light eye shading.
EyeShadeNormal	Normal shade.

An enumEyeShade value which determines the type of eye shade to use.

EyeGlareFull	Strong image glare.
EyeGlareNone	No glare.
EyeGlareSlight	Slight image glare.

An enumEyeGlare value which determines the type of eye shade to use.

bUseEditRectangles

When true, previously detected redeye rectangles are used to correct red eyes.

When false, the algorithm detects rectangles with red eyes and corrects them. Existing rectangles are ignored when correcting red eyes.

Remarks

The algorithm searches for rectangles containing red eyes, and corrects the red eyes.

This method accurately corrects red eyes without modifying non-eyes in most cases without any intervention. However, as with any algorithm, there is a potential for false positives (modifications of areas that are not eyes), or red eyes that are not corrected in some images.

To provide the application with maximum control over this behavior, this method stores in the Redeye properties all areas that have been corrected as a collection of rectangles with corresponding correction information. The rectangles identify areas in which red-eyes were detected and corrected, and a value indicating the confidence that the area corrected was a red eye. This enables the application to set an acceptable level of false positives, and optimize red-eye correction.
