XmInstallImage 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 installation process does not make a local copy of the image. Therefore,
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 .Xdefaults 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.
