Hello all,

I'm trying to make a 3D transformation with image data. For the 3rd 1 D
transformation I have to jump in a 12Gbyte file, to get the data for the
transformation. The jumpimg in the file cost a lot of time. I am doing the
filehandling with help of the filestream and binaryreader class in C#. Is
there an other (faster) way existing, to read the data out of the file?

Thanks in advance,

regards

Gregor

Gregor,

You might get faster performance by using just the FileStream, and
converting the items in the list yourself.

When using the BinaryReader, it might be buffering information. You
should make sure that your stream is set to the position you want to begin
reading from before you pass it to the BinaryReader.

Hope this helps.
