Image Programs Versus Script Programs - Quantum Data 881 User Manual

Image programs versus script programs

882 Video Test Instrument User Guide (Rev. A.35)
The SDK is launched from the Quantum Data SDK list item on the generator's home page.
If the SDK is not yet installed, the user will be prompted through the installation process
which includes connecting to the Quantum Data website. Therefore, an internet
connection is required. If the older command-line version of the Image SDK is already
installed on the system, it will be replaced by the Quantum Data SDK. The installation
program can save the original SDK on the computer.
For first-time installation, an internet connection is required so that the automatic
installation process can retrieve the installation package from the Quantum Data website.
If the host computer does not yet have JRE, it can be downloaded from the java.com
website, or via a link near the bottom of the generator's home page.
When the Quantum Data SDK is launched, the user has a choice of Image SDK or
ScriptSDK, depending on the type of application to be developed. When the SDK is
running, the user can freely switch between Image SDK and Script SDK at any time.
The Image SDK is used to create resolution-independent test patterns and other display
images. When an image is loaded from the SDK into the generator via the Load & Execute
menu selection, it is displayed immediately. An image load consists of a file transfer and
the commands IMGP, IMGL, and IMGU. After loading the image via the SDK, the image is
then available to be selected for display via browse mode.
The ScriptSDK is used to create executable programs that can be stored in the generator
and run from the SDK menu. A ScriptSDK program can contain any commands in the 880
command language, as well as user menus, responses to key presses, numeric input, and
output to the serial port.
