218 Chapter 7 Working with Images
Overview
The 882 generator includes a library of 250 test images. The images in the library are
compiled in the application and stored as .img files; you cannot modify them.
In addition to the library images there are other types of images that you can create and
store on the generator media. You can create your own images either by writing your own
code using the generator’s Software Development Kit (SDK) or by entering image
primitive commands using the command line interface. Furthermore, you can render
JPEG images stored on the generator media or a file server PC.
Using the SDK, you can create complex, custom images through the C/C++ API. When
you create images through the API, they reside on the generator as object files. You can
then render them by selecting the image through the front panel or through the command
line interface. When you select one of these images, it gets linked, compiled, and stored in
the generator’s cache. Please refer to the SDK manual for details on creating custom
images using the API.
You can create static images through the command line interface using the image
primitive commands, such as RECT (draw rectangle), OVAL (draw oval), Line (draw line),
and so on. You can select the grayscale and color tables used in the image and save the
images in flash memory. Drawing commands are processed by the generator and stored
as XML files. These XML files can be modified if necessary.
JPEG and bitmap images can be stored on any of the generator media and rendered just
like any other image type through the Contents key.
This chapter provides procedures for viewing lists of images, creating images using the
drawing primitive commands, rendering bitmap and jpg images, and creating image
catalogs.
