mlib_ImageClearEdge_Fp(3MLIB) mediaLib Library Functions mlib_ImageClearEdge_Fp(3MLIB)NAME
mlib_ImageClearEdge_Fp - sets edges of an image to a specific color
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_ImageClearEdge_Fp(mlib_image *img, mlib_s32 dx,
mlib_s32 dy, const mlib_d64 *color);
DESCRIPTION
The mlib_ImageClearEdge_Fp() function sets edges of an image to a specific color. This function can be used in conjunction with the con-
volve and other spatial functions to fill in the pixel values along the edges. The data type of the image can be MLIB_FLOAT or MLIB_DOUBLE.
PARAMETERS
The function takes the following arguments:
img Pointer to an image.
dx Number of columns on the left and right edges of the image to be cleared.
dy Number of rows at the top and bottom edges of the image to be cleared.
color Array of color values by channel. color[i] contains the value for channel i.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.

mlib_ImageCopyArea(3MLIB) mediaLib Library Functions mlib_ImageCopyArea(3MLIB)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.
