Effect functions
SubsectionsFreeImage_Clone
void *FreeImage_Clone(void *dib);
Makes an exact duplicate of the given image. FreeImage_Blur
void FreeImage_Blur(void *dib);
Applies an averaging filter on the bitmap. FreeImage_Brighten
void FreeImage_Brighten(void *dib, double factor);
Brightens the bitmap with the given factor. FreeImage_Darken
void FreeImage_Darken(void *dib, double factor);
Darkens the bitmap with the given factor. FreeImage_MaskCombine24
void FreeImage_MaskCombine24(void *dib1, void *dib2, void *mask, int x, int y);
Combines two images using the given alpha mask. The parameters mean the following:
Description
Target bitmap
dib2
Source bitmap
mask
Alpha mask (8-bit grayscale image)
x
x-position, where the source bitmap will be stored in the target bitmap
y
y-position, where the source bitmap will be stored in the target bitmap
FreeImage_MaskCombine24Ex
void FreeImage_MaskCombine24Ex(void *pdst, int dstx, int dsty, unsigned int width, unsigned int height, void *psrc, void *pmask, int srcx, int srcy);
Combines two images using the given alpha mask. The parameters mean the following:
Description
Target bitmap
dstx
x-position, where the source bitmap will be stored in the target bitmap
dsty
y-position, where the source bitmap will be stored in the target bitmap
width
Width of the target bitmap
height
Height of the target bitmap
psrc
Source bitmap
pmask
Alpha mask (8-bit grayscale image)
srcx
Clip rectangle left
srcy
Clip rectangle top
FreeImage_MaskCombine32
void FreeImage_MaskCombine32(void *dib1, void *dib2, int x, int y);
Combines two images using the alpha mask stored in the source bitmap. The parameters mean the following:
Description
Target bitmap
dib2
Source bitmap
x
x-position, where the source bitmap will be stored in the target bitmap
y
y-position, where the source bitmap will be stored in the target bitmap
FreeImage_MaskCombine32Ex
void FreeImage_MaskCombine32Ex(void *pdst, int dstx, int dsty, unsigned int width, unsigned int height, void *pSrc, int srcx, int srcy);
Combines two images using the alpha mask stored in the source bitmap. The parameters mean the following:
Description
Target bitmap
dstx
x-position, where the source bitmap will be stored in the target bitmap
dsty
y-position, where the source bitmap will be stored in the target bitmap
width
Width of the target bitmap
height
Height of the target bitmap
psrc
Source bitmap
srcx

FreeImage_AddAlphaMask
void FreeImage_AddAlphaMask(void *dib, void *mask);
Loads the given alpha mask into the 32-bit bitmap. FreeImage_Crop
void *FreeImage_Crop(void *dib, int left, int top, int right, int bottom);
Copies the bitmapdata in the given rectangle into a new bitmap and returns it. FreeImage_Flip
void FreeImage_Flip(void *dib);
Flips the given bitmap. E.g. turns it upside down. FreeImage_Mirror
void FreeImage_Mirror(void *dib);
Mirrors the given bitmap. FreeImage_Invert
void FreeImage_Invert(void *dib);
Inverts the colors of the given bitmap. FreeImage_Rotate
void *FreeImage_Rotate(void *dib, int angle);
Rotates the given bitmap on the given angle. The result is a new bitmap, with the same size as the source bitmap but with the bitmap content rotated. Copyright 2000 Floris van den Berg (freeimage@wxs.nl) |
