Creating custom images
This section describes how to create images and add them to the generator’s image
library, and how to customize the image list. The recommended method for creating
images is create a text file containing the commands for creating the image, and then
downloading the text file to the generator. Another method for creating images is to use
the Image Editor in VGM to create a basic image, save the basic image as a command file
in VGM, and then open and edit the command file to refine the image as needed.
To create custom images with a command file:
1. Using a text editor, open a text file (command file) on your computer and enter the
following commands.
0
// gates all video and sync outputs off
new_image
// creates a new image
// begin an image editing session
640
// sets the horizontal resolution
480
// sets the vertical resolution
.
.
// other image parameters
.
// ends an image editing session
new_image
// saves image as new_image
OUTG 1
// gates all video and sync outputs on
// draws the image
// applies the buffer to the generator hardware
2. Save the text file, using a *.txt extension.
3. Establish a terminal session with the generator. See “
Setting up a terminal connection
4. At the R:> prompt, transfer the text file to the generator. For example, to transfer a file
using HyperTerminal, do the following:
a.
On the
Transfer
menu, click
Send Text File
. The
Send Text File
dialog box
appears.
b.
Select the text file you want to send, and then click
Open
. HyperTerminal displays
the commands as they are sent.
c.

Enter
once to ensure that the last command is sent.
5. Assign the image to Image knob list by entering the following commands:
IMG
// loads image directory into edit buffer
// begins a directory editing session
20 new_image // assigns image to image knob list at 20
// ends a directory editing session
// saves contents of directory as current name
