Creating image catalogs
An image catalog is an XML file that lists image names. When a catalog is enabled, the
image names in the catalog appear in the Content list. You can create image catalogs and
use them to control which image names appear when you press the Content key. If your
test environment requires only a subset of the built-in images (for example, only images
for testing TV CRTs), you can create an image catalog containing only those image
names. You can arrange the image names in the order you want them to appear in the
Content list, and you can create multiple catalogs and use them simultaneously. You can
create an image catalog with images from the default library or custom images created
either with the SDK or through the command line.
Creating image catalogs is a two-step process. The first step is to create the catalog. The
second step is to add the catalog to the Content library. Once in the Content library, you
can enable one or more catalogs to control which images appear when you press the
Content key.
Creating an image catalog
The process for creating image catalogs is somewhat different than creating format
catalogs. The generator is not configured with an image catalog library as there is for
formats. Therefore you first have to create an image library (ImageLib) to put the image
catalogs in. Also the images are stored in cache and because of this there is some
administration overhead involved in re-establishing the default content list of images that
is not required for the source list of formats.
Image catalogs are created using the command line interface. Although the catalog itself
is a file, you will use the Directory (DIR) commands to create the file. Follow the
procedures below to create an image catalog and add it to the Content library.
