0N/A * FUNCTIONS
0N/A * mlib_ImageConvClearEdge - Set edge of an image to a specific color.
0N/A *
0N/A * SYNOPSIS
0N/A * mlib_status mlib_ImageConvClearEdge(mlib_image *dst,
0N/A * mlib_s32 dx_l,
0N/A * mlib_s32 dx_r,
0N/A * mlib_s32 dy_t,
0N/A * mlib_s32 dy_b,
0N/A * const mlib_s32 *color,
0N/A * mlib_s32 cmask)
0N/A *
0N/A * ARGUMENT
0N/A * dst Pointer to an image.
0N/A * dx_l Number of columns on the left side of the
0N/A * image to be cleared.
0N/A * dx_r Number of columns on the right side of the
0N/A * image to be cleared.
0N/A * dy_t Number of rows on the top edge of the
0N/A * image to be cleared.
0N/A * dy_b Number of rows on the top edge of the
0N/A * image to be cleared.
0N/A * color Pointer to the color that the edges are set to.
0N/A * cmask Channel mask to indicate the channels to be convolved.
0N/A * Each bit of which represents a channel in the image. The
0N/A * channels corresponded to 1 bits are those to be processed.
0N/A *
0N/A * RESTRICTION
0N/A * dst can have 1, 2, 3 or 4 channels of MLIB_BYTE or MLIB_SHORT or MLIB_INT
0N/A * data type.
0N/A *
0N/A * DESCRIPTION
0N/A * Set edge of an image to a specific color. (VIS version)
0N/A * The unselected channels are not overwritten.
0N/A * If src and dst have just one channel,
0N/A * cmask is ignored.
