Correcting Colors

The following functions are designed specifically for adjusting colors in an image:

Function Purpose
LBitmap::AntiAlias Applies an anti-aliasing filter to a specific bitmap.
LBitmap::AntiAlias2 Applies an anti-aliasing filter to a specific bitmap, it support Signed data images.
LBitmap::AdjustTint Adjusts the bitmap tint by changing the colors in an image using two separate color wheel rotations.
LBitmap::ApplyMathLogic Performs specific Mathematical or logical operations on the colors of a bitmap.
LBitmap::AutoColorLevel Makes dark values darker and light values lighter to automatically enhance shadows and brighten the image.
LBitmap::BalanceColors Linearizes the number of pixels in a bitmap across RGB, YUV or Gray color space.
LBitmap::ChangeHue Changes the hue of colors in a bitmap by rotating the color wheel.
LBitmap::ChangeHueSatInt Changes the hue, saturation and brightness of all or specified colors in the image. This function combines the functionality found in the LBitmap::ChangeHue, LBitmap::ChangeSaturation, and LBitmap::ChangeIntensity functions and allows you to change the overall hue, saturation and intensity all at one time, or adjust the parameters separately, or make adjustments in successive passes.
LBitmap::ChangeSaturation Increases or decreases the saturation of colors in a bitmap.
LBitmap::ChannelMix Rebalances the colors in a bitmap in order to make color adjustments and to correct images which have more color than others.
LBitmap::ColorIntensityBalance Changes the distribution of the red, green, or blue channels.
LBitmap::ColorizeGray Colors an 8, 12 or 16-bit grayscale bitmap. The function changes the color bits/pixel of the bitmap from the specified formats into 24-bit RGB format.
LBitmap::ColorLevel Applies color leveling to an image. It changes the image shadows, midtones and highlights.
LBitmap::ColorReplace Replaces specified colors by adjusting values of hue, saturation and brightness.
LBitmap::ColorThreshold Using any one of eight color spaces, resets those bitmaps pixel component values that fall inside or outside of a specified range.
LBitmap::ColorHalfTone Creates an enlarged halftone screen for each image channel.
LBitmap::Invert Inverts the colors in the specified bitmap, making it like a photographic negative.
LBitmap::RemapHue Changes a bitmap's hue values using a lookup table.
LBitmap::RemoveRedEye Replaces the red component of the pixels with the specified color. To replace only the red component for those pixels in the eyes of the bitmap, select a small region around the eye(s).
LBitmap::SampleTarget Corrects color values by shifting the sample colors to the target colors.
LBitmap::SelectData Selects a specified number of bits of an 8, 12 or 16-bit grayscale bitmap and puts them into a mask, then colors the bitmap depending on the mask. This can show bitmap variances depending on user-defined conditions.
LBitmap::SelectiveColor Changes the color of a bitmap by altering the definitions of one or more colors used by the bitmap.
LBitmap::ShiftData Selects a specified number of bits from an 8, 12 or 16-bit grayscale bitmap into a mask and places the mask in a new 8, 12 or 16-bit grayscale bitmap.
LBitmap::SwapColors Swaps colors channels in a bitmap.
