mediaLib Library Functions              mlib_ImageCopyArea(3MLIB)



NAME
     mlib_ImageCopyArea - copy an area

SYNOPSIS
     cc [ flag... ] file... -lmlib [ library... ]
     #include 

     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  rec-
     tangular  area from one portion of the image to another por-
     tion 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.
