NAME

       mlib_ImageCreateSubimage - subimage creation

SYNOPSIS

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

       mlib_image *mlib_ImageCreateSubimage(mlib_image *img, mlib_s32 x,
	    mlib_s32 y, mlib_s32 w, mlib_s32 h);

DESCRIPTION

       The  mlib_ImageCreateSubimage() function creates a mediaLib image data structure for a subimage based on a source image. Note that the mem-
       ory space of the source image data is used for the subimage data. The data type of  the	image  can  be	MLIB_BIT,  MLIB_BYTE,  MLIB_SHORT,
       MLIB_USHORT, MLIB_INT, MLIB_FLOAT, or MLIB_DOUBLE.

PARAMETERS

       The function takes the following arguments:

       img    Pointer to source image.

       x      X coordinate of subimage origin in the source.

       y      Y coordinate of subimage origin in the source.

       w      Width of the subimage in pixels.

       h      Height of the subimage in pixels.

RETURN VALUES

       The function returns a pointer to the mlib_image data structure.

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.
