This function reduces an image by dividing it into nMaxColors equal-sized squares.

 Copy Code |
|
|---|---|
AT_ERRCOUNT ACCUAPIIG_IP_color_reduce_median_cut (
HIGEAR hIGear,
BOOL bFastRemap,
UINT nMaxColors
);
|
|
Arguments:
| hIGear | HIGEAR handle of image. |
| bFastRemap | Set = TRUE for reduction algorithm optimized for speed. Set = FALSE for algorithm optimized for quality. |
| nMaxColors | The maximum number of colors (that is, maximum number of unique pixel values) you want in the resulting image. Must be 16 to 256. |
Return Value:
Returns the number of ImageGear errors that occurred during this function call.
Supported Raster Image Formats:
Indexed RGB – 4, 8 bpp;
Grayscale – 4, 8 bpp;
RGB – 24 bpp.
Sample:
None
Example:
| Copy Code |
|
|---|---|
HIGEAR hIGear; /* HIGEAR handle of image */ /* Reduce to 64 colors using median cut algorithm */ IG_IP_color_reduce_median_cut ( hIGear, FALSE, 64 ); |
|
Remarks:
The colors of the pixels in each square will be averaged to produce a resulting color. The resulting image will contain only these colors.
