Reading and writing uncompressed AVI [message #59606]

Dear all,

I have recently tried to read (and write) uncompressed 8bit gray scale
AVIs with IDL. I found Kilvarock's aviIDL63.zip and tried it out - but
I don't get it to work... Can anybody help me there? What do I have to
do if I want to read (and write) an AVI written as Y800 codec (which
is uncompressed 8bit gray scale)? Is it possible at all?

When I use testavigenreader and read one of the files, width, height,
and numberOfFrames are all zero.

Before I found aviIDL63.zip I had already written a routine which
reads uncompressed avis. I'm also able to write them, sort of, as
there are some bits that I couldn't work out (the bit about the color
tables). At least the program I wanted to use them with (Registax)
understands them. Other programs don't and complain about an unknown
codec...

Michael
