.SH "NAME"
\fBXmGetScaledPixmap\fP \(em read a pixmap file and scale it according to pixmap and print resolution
.SH "SYNOPSIS"
.PP
.nf
#include <Xm/Xm\&.h>
\fBXtEnum \fBXmGetScaledPixmap\fP\fR(
\fBWidget \fBwidget\fR\fR,
\fBString \fBimage_name\fR\fR,

.fi
.SH "DESCRIPTION"
.PP
\fBXmGetScaledPixmap\fP uses its
\fBWidget\fP
argument to look up
for a Print Shell ancestor to get the pixmap resolution
and the default printer resolution information to be used
if
\fBscaling_ratio\fP
\fB==0\fP\&.
.PP
If scaling is 0, and a valid PrintShell is present
\fBXmGetScaledPixmap\fP
applies a ratio equals to
(printer resolution / default pixmap resolution)
before creating the Pixmap on the widget\&'s Screen\&.
Otherwise, the
\fBscaling_ratio\fP
is used in scaling
both dimensions of the image being converted as a Pixmap\&.
.PP
\fBXmGetScaledPixmap\fP completes the
\fBXmGetPixmapByDepth\fP existing
API by making use of the
\fBXmNdefaultPixmapResolution\fP
of the rooting
\fBXmPrintShell\fP\&.
Refer to the
\fBXmGetPixmapByDepth\fP documentation for details\&.
.IP "\fIwidget\fP" 10
Widget used to determine the default pixmap resolution (of the print shell ancestor)\&.
.IP "\fIimage_name\fP" 10
See XmGetPixmapByDepth for description\&.
.IP "\fIforeground\fP" 10
See XmGetPixmapByDepth for description\&.
.IP "\fIbackground\fP" 10
See XmGetPixmapByDepth for description\&.
.IP "\fIdepth\fP" 10
See XmGetPixmapByDepth for description\&.
.IP "\fIscaling_ratio\fP" 10
Indicate the scaling ratio to be applied, or 0\&.
.SH "RETURN VALUE"
.PP
Returns Pixmap or NULL if failed\&.
.SH "ERRORS/WARNINGS"
.PP
Same as for \fBXmGetPixmapByDepth\fP\&.
