A number of rules relating to gif images
The three times given in the display of the MB Panel are:
o
Repaint from the video cache
o
Decompress to the video cache in the event of a URL jump and after starting (virtually linear
with number of pixels).
o
File transfer time via the link if not local
If the overall size of the gif images is the same, one big image (max. 512 kB) is better than two
smaller ones.
Recommended max. size 798 x 598 pixels (one pixel all round free)
It is better to use the same image several times in a project because it only needs to be trans-
ferred, decompressed and saved in the video cache once. For example, give it in the teq file for
the general background.
9.4.1 Decompressing to the video cache when starting using the gif list
This solution allows you to decompress gif files to the video cache
in the "background"
.
Advantage: You do not need to wait for decompression to end before the first page is shown.
The first page is shown immediately (as with a project without a gif list) and you do not need to wait
until all gif files in the gif list have been decompressed. Decompression continues in the background
until the video memory in the case of multiple gif files in the gif list is full.
Operation of:
- Open Microsoft
®
Notepad Editor
- Write the following head text for the file:
[PATH]
INTFLASH:/WebPages
[FILE]
- Enter the name of all gif files (as listed in the local INTFLASH/WebPages directory).
- Save the file under the name "GifList.txt".
Example of a GifList.txt
- Copy of the GifList.txt under INTFLASH/Config/
