NAMEXmInstallImage — A pixmap caching function that adds an image to the
image cache
SYNOPSIS
#include <Xm/Xm.h>
Boolean XmInstallImage(
XImage * image,
char * image_name);
DESCRIPTIONXmInstallImage stores an image in an image cache that can later be used
to generate a pixmap. Part of the installation process is to extend
the resource converter used to reference these images. The resource
converter is given the image name so that the image can be referenced
in a .Xdefaults file. Since an image can be referenced by a widget
through its pixmap resources, it is up to the application to ensure
that the image is installed before the widget is created.
image Points to the image structure to be installed. The installa‐
tion process does not make a local copy of the image. There‐
fore, the application should not destroy the image until it
is uninstalled from the caching functions.
image_name
Specifies a string that the application uses to name the
image. After installation, this name can be used in .Xde‐
faults for referencing the image. A local copy of the name is
created by the image caching functions.
The image caching functions provide a set of eight preinstalled images.
These names can be used within a .Xdefaults file for generating pixmaps
for the resource for which they are provided.
