.TH "XmGetScaledPixmap" "library call"

.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,

\fBPixel \fBforeground\fR\fR,

\fBPixel \fBbackground\fR\fR,

\fBint \fBdepth\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\&.
