XmGetScaledPixmap

read a pixmap file and scale it according to pixmap and print resolution

Format

#include <Xm/Xm.h>
XtEnum XmGetScaledPixmapWidget
widgetString image_namePixel
foregroundPixel backgroundint
depthDouble scaling_ratio

DESCRIPTION

XmGetScaledPixmap uses its Widget argument to look up for a Print Shell ancestor to get the pixmap resolution and the default printer resolution information to be used if scaling_ratio ==0.

If scaling is 0, and a valid PrintShell is present XmGetScaledPixmap applies a ratio equals to (printer resolution / default pixmap resolution) before creating the Pixmap on the widget's Screen. Otherwise, the scaling_ratio is used in scaling both dimensions of the image being converted as a Pixmap.

XmGetScaledPixmap completes the XmGetPixmapByDepth existing API by making use of the XmNdefaultPixmapResolution of the rooting XmPrintShell. Refer to the XmGetPixmapByDepth documentation for details.
