Instructions for Bitmap Picture Download:
The bit map download function in VGM allows you to display, using the video
generator, an image stored as a BMP file by your computer. The bit map is
transferred directly to the video memory and the color information in the file is
transferred directly to the color lookup table memory. Selecting another test
image or video format will clear the displayed bit-mapped image. There is no way
to store the BMP file in the generator's user memory.
NOTE: The bit map download operation does not clear the current displayed test
image. It will only over write the portion of active video that matches the size and
offset of the downloaded image. The download operation will modify the color
lookup table values. This may cause the color to change on other portions of the
screen. If you want to start with a blank screen, you should first display the
“raster” test image.
1. Requirements to download a bit mapped image file to a generator:
- The target generator firmware must
support the bit map download function.
- The bit mapped image file must be stored
on the computer as an uncompressed .BMP
file.
- VGM must have communications open
with the target generator
2. Select Tools -> Image Download from the
Main VGM Screen. This will open the Image
Download Utility Screen shown here.
3. Select the target generator from the pull-
down ”Select a Generator” list. The active
video dimensions (in pixels) of the current
video format being produced by the genera-
tor will be shown in the Screen Dimensions”
area of the Image Download screen.
4. You must check the "Serial Option / Use
Ymodem" check box when downloading the
image via a serial port connection. If you do not put a check in the box, the
software will attempt to use a USB connection for the download. The software
may stop responding if the box is not checked and there is no USB connection to
the generator.
