Image file size limit

Does Raster Design 2004 have any limitations on the amount of data it can
load ? I understand that images can be "tiled" so that only the section
under view is actually loaded into memory. Correct or not ?

For example, if I wish to simultaneously load 6 tiffs each of 1 Gb in size,
can I ?

Kind regards

Hi Mark,

Raster Design uncompresses the image file before to open it. So if you have
a 300MB compressed file it is possible that it is going to need 3GB
uncompressed. If the uncompressed size of the image is more than 2GB, then
Raster Design will not be able to open the image.

If you are having trouble loading/inserting images, here are several
troubleshooting steps you can take:

1) Watch the image swap file size as you are opening or processing your
images. See if it's size approaches 2 GB.
The file can be found by looking for a large, recently created file in your
%TEMP% folder with a name like "IExxxx.TMP" (Start > Run > CMD - type %TEMP%
to find this folder)

2) Prior to importing the images, try to save them as TIFF uncompressed in
another program if possible. The goal will be to prevent the Image SWAP
file from growing above 2 GB.

Suggestions:

1) Make sure not to set your Raster Design "Memory Limit" too high. If you
have 1 GB of RAM, I wouldn't set it much higher than 600 MB. Performance can
be slow if AutoCAD tries to grab more RAM than your system actually has
free.

2) Export your image file to TIFF, TILED, UNCOMPRESSED. This will prevent
the SWAP file from growing when the image is being opened. This in turn
will give Raster Design more "room" to work with when you are Editing your
images later.

3) You can convert the TIFF files back to the original format after you are
done processing them in Raster Design.

I hope this information helps.

Hi Mark,

The same limitation exists in Raster Design - the IExxxx.TMP file cannot
exceed 2 gigabytes. When you open a compressed file, Raster Design needs to
decompress the file to work with it natively. The decompressed size may
exceed 2 GB, thus you will not be able to work with the image. The best
solution is to work with the images in an uncompressed state (thus TIFF,
TILED, UNCOMPRESSED) and display only the images that you need to work with.

Dear Jon
Thanks. We are not yet using RD but are about to upgrade Map 2000i to Map
Series. 2000i has the same swap file limit. If I run RD under Windows XP Pro
what is the maximum RAM that RD will access under XP Pro ?

What I would like to know is a bit more about tiling in RD. What is tiling
and how does it work ? I see the webiste offers an RD free trial but there
is no link. Any ideas ?

Cheers

Mark

Thanks Jon

Is there a link to download the trial rather than order it on CD ?

Mark

Hi Mark,

No, the file is not available for download. You'd have to fill out the form
and have a reseller send a CD to you.
