XmGetScaledPixmap - Man Page
read a pixmap file and scale it according to pixmap and print resolution
Synopsis
#include <Xm/Xm.h> XtEnum XmGetScaledPixmap( Widget widget, String image_name, Pixel foreground, Pixel background, int depth, Double 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.
- widget
Widget used to determine the default pixmap resolution (of the print shell ancestor).
- image_name
See XmGetPixmapByDepth for description.
- foreground
See XmGetPixmapByDepth for description.
- background
See XmGetPixmapByDepth for description.
- depth
See XmGetPixmapByDepth for description.
- scaling_ratio
Indicate the scaling ratio to be applied, or 0.
Return Value
Returns Pixmap or NULL if failed.
Errors/Warnings
Same as for XmGetPixmapByDepth.
