NAME

       mlib_ImageCopyArea - copy an area

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_ImageCopyArea(mlib_image *img, mlib_s32 x, mlib_s32 y,
	    mlib_s32 w, mlib_s32 h, mlib_s32 dx, mlib_s32 dy);

DESCRIPTION

       The  mlib_ImageCopyArea()  function copies a specified rectangular area from one portion of the image to another portion of the same image.
       The data type of the image can be MLIB_BIT, MLIB_BYTE, MLIB_SHORT, MLIB_USHORT, MLIB_INT, MLIB_FLOAT, or MLIB_DOUBLE.

       It uses the following equation:

	 img[x+dx+i][y+dy+j][i] = img[x+i][y+j][i]

       where i = 0, 1, ..., w-1; j = 0, 1, ..., h-1.

PARAMETERS

       The function takes the following arguments:

       img    Pointer to source image.

       x      X coordinate of the area origin in the source.

       y      Y coordinate of the area origin in the source.

       w      Width of the area to be copied.

       h      Height of the area to be copied.

       dx     Horizontal displacement in pixels of the area to be copied.

       dy     Vertical displacement in pixels of the area to be copied.

RETURN VALUES

       The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
