AdjustColorBalance Method

Description

Overrides the default parameters when auto color balancing the image.

Syntax

Visual Basic
Public Sub AdjustColorBalance( _ ByVal Color As Integer, _ ByVal Red As Integer, _ ByVal Green As Integer, _ ByVal Blue As Integer _ )

Parameters

Color

The color parameter of the auto color balance algorithm, defining the strength of color case and contrast correction to be applied to the image.
range: 0 - 100

0 indicates no correction of the image
Values greater than zero increase the amount of correction performed

Red

The red color parameter of the auto color balance algorithm result.
range: -100 to 100

0 indicates no change to the red component of the image. (Red component will be the same as in the original image.)
Values less than zero decrease the red component of the image.
Values greater than zero increase the red component of the image.

Green

The green color parameter of the auto color balance algorithm result.
range: -100 to 100

0 indicates no change to the green component of the image. (Green component will be the same as in the original image.)
Values less than zero decrease the green component of the image.
Values greater than zero increase the green component of the image.

Blue

The blue color parameter of the auto color balance algorithm result.
range: -100 to 100

0 indicates no change to the blue component of the image. (Blue component will be the same as in the original image).
Values less than zero
Values greater than zero increase the blue component of the image.

Remarks

This method applies the same algorithm as AutoColorBalance, to automatically balance color in the image, but enables the user to override the default parameters of the algorithm.

Since pixel values must fall within the range 0-255, resulting pixel values less than 0 are set to 0 and resulting pixel values greater than 255 are set to 255.
