int           iPixels,
int           iShowProgress,
HWND  hParent)

Description

Mozaic filter is an artistic filter modeling mosaic images. The filter separates the image into small matrices, and computes the average of these matrices. The size of the matrix can be tuned by the iPixels paramete. This function works for only 8 bit per pixel and 24 bit per pixel images.

Examples

source                                                    mozaic           

The original 160 x 170 pixel image and the result image with iPixels = 10.

Parameters

HDIB

hDIB

Handle of the DIB to filter.

int

iPixels

Size of the matrix, cannot be less than zero.

int
