Correcting Colors

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

Function

Purpose

L_AdjustBitmapTint

Adjusts the bitmap tint by changing the colors in an image using two separate color wheel rotations.

L_AntiAliasBitmap

Applies an anti-aliasing filter to a specific bitmap.

L_ApplyMathLogicBitmap

Performs specific Mathematical or logical operations on the colors of a bitmap.

L_AutoColorLevelBitmap

Makes dark values darker and light values lighter to automatically enhance shadows and brighten the image.

L_BalanceColors

Linearizes the number of pixels in a bitmap across RGB, YUV or Gray color space.

L_BumpMapBitmap

Adds a three-dimensional texture pattern by applying the bump image to the destination image.

L_ChangeBitmapHue

Changes the hue of colors in a bitmap by rotating the color wheel.

L_ChangeBitmapSaturation

Increases or decreases the saturation of colors in a bitmap.

L_ChannelMix

Rebalances the colors in a bitmap in order to make color adjustments and to correct images which have more color than others.

L_ChangeHueSatIntBitmap

Changes the hue, saturation and brightness of all or specified colors in the image. This function combines the functionality found in the L_ChangeBitmapHue, L_ChangeBitmapSaturation, and L_ChangeBitmapIntensity 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.

L_ColorHalfToneBitmap

Creates an enlarged halftone screen for each image channel.

L_ColorReplaceBitmap

Replaces specified colors by adjusting values of hue, saturation and brightness.

L_ColorThresholdBitmap

Using any one of eight color spaces, resets those bitmaps pixel component values that fall inside or outside of a specified range.

L_ColorIntensityBalance

Changes the distribution of the red, green, or blue channels.

L_ColorizeGrayBitmap

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.

L_ColorLevelBitmap

Applies color leveling to an image. It changes the image shadows, midtones and highlights.

L_CubismBitmap

Remaps the bitmap into a collection of rotated rectangles (cubic faces), in the Cubist style.

L_DrawStarBitmap

Draws a star on the bitmap.

L_DryBitmap

Simulates painting an image with the watercolor dry brush technique.

L_FreePlaneBendBitmap

Wraps the bitmap onto a 3D plane shaped by pnCurve.

L_FreeRadBendBitmap

Wraps the bitmap along its radius on a 3D surface shaped by pnCurve.

L_GlassEffectBitmap

Divides the image into cells and makes it look as if it is being viewed through glass blocks.

L_GlowFilterBitmap

Makes colored edges shine with a neon-like glow.

L_InvertBitmap

Inverts the colors in the specified bitmap, making it like a photographic negative.

L_LensFlareBitmap

Simulates the secondary reflections caused when bright lights are facing the camera lens.

L_LightBitmap

Adds many spots of directed light sources to the bitmap.

L_LightControlBitmap

Lightens or darkens all or part of a bitmap by remapping the pixel values.

L_OceanBitmap

Reflects the bitmap on an ocean surface.

L_SampleTargetBitmap

Corrects color values by shifting the sample colors to the target colors.

L_PlaneBendBitmap

Places the bitmap on parallel planes along the Z-axis bent towards a center point.

L_PlaneBitmap

Places the bitmap on parallel planes along the Z-axis.

L_RemapBitmapHue

Changes a bitmap's hue values using a lookup table.

L_SampleTargetBitmap

Corrects color values by shifting the sample colors to the target colors.

L_SelectiveColorBitmap

Changes the color of a bitmap by altering the definitions of one or more colors used by the bitmap.

L_SmoothEdgesBitmap

Smoothes the rough edges in the bitmap.

L_SelectBitmapData

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.

L_ShiftBitmapData

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.

L_SwapColors

Swaps colors channels in a bitmap.

L_RemoveRedeyeBitmap

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).

L_TunnelBitmap

Places the bitmap inside a tunnel along the Z-axis.
