.SH SYNOPSIS
.LP
.nf
cc [ \fIflag\fR... ] \fIfile\fR... \fB-lmlib\fR [ \fIlibrary\fR... ]
#include <mlib.h>

\fBmlib_status\fR \fBmlib_ImageSetPaddings\fR(\fBmlib_image *\fR\fIimg\fR, \fBmlib_u8\fR \fIleft\fR,
     \fBmlib_u8\fR \fItop\fR, \fBmlib_u8\fR \fIright\fR, \fBmlib_u8\fR \fIbottom\fR);
.fi

.SH DESCRIPTION
.sp
.LP
The \fBmlib_ImageSetPaddings()\fR function sets new values for the \fBpaddings\fR field of the \fBmlib_image\fR structure as follows:
.sp
.in +2
.nf
img->paddings[0] = left;
img->paddings[1] = top;
img->paddings[2] = right;
img->paddings[3] = bottom;
.fi
.in -2

.sp
.LP
By default, an image structure creation function, such as \fBmlib_ImageCreate()\fR, \fBmlib_ImageCreateStruct()\fR, or \fBmlib_ImageCreateSubimage()\fR, sets the paddings field of the mlib_image structure as follows:
.sp
.in +2
.nf
img->paddings[0] = 0;
img->paddings[1] = 0;
img->paddings[2] = 0;
img->paddings[3] = 0;
.fi
.in -2

.sp
.LP
Note that this function is needed only when the edge condition \fBMLIB_EDGE_SRC_PADDED\fR is used.
.sp
.LP
The \fBmlib_image->paddings\fR field denotes the amount of paddings on each side of an image, from which the real image border can be seen. When \fBMLIB_EDGE_SRC_PADDED\fR is specified as the edge condition, a geometric function uses the "real" source image border for clipping the destination image.
