The following functions are designed specifically for adjusting colors in an image:
Function |
Purpose |
Applies an anti-aliasing filter to a specific bitmap. |
|
Applies an anti-aliasing filter to a specific bitmap, it support Signed data images. |
|
Adjusts the bitmap tint by changing the colors in an image using two separate color wheel rotations. |
|
Performs specific Mathematical or logical operations on the colors of a bitmap. |
|
Makes dark values darker and light values lighter to automatically enhance shadows and brighten the image. |
|
Linearizes the number of pixels in a bitmap across RGB, YUV or Gray color space. |
|
Changes the hue of colors in a bitmap by rotating the color wheel. |
|
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. |
|
Increases or decreases the saturation of colors in a bitmap. |
|
Rebalances the colors in a bitmap in order to make color adjustments and to correct images which have more color than others. |
|
Changes the distribution of the red, green, or blue channels. |
|
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. |
|
Applies color leveling to an image. It changes the image shadows, midtones and highlights. |
|
Replaces specified colors by adjusting values of hue, saturation and brightness. |
|
Using any one of eight color spaces, resets those bitmaps pixel component values that fall inside or outside of a specified range. |
|
Creates an enlarged halftone screen for each image channel. |
|
Inverts the colors in the specified bitmap, making it like a photographic negative. |
|
Changes a bitmap's hue values using a lookup table. |
|
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). |
|
Corrects color values by shifting the sample colors to the target colors. |
|
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. |
|
Changes the color of a bitmap by altering the definitions of one or more colors used by the bitmap. |
|
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. |
|
Swaps colors channels in a bitmap. |
