Hi - can you tell me if the attached file is a format recognized by LEAD, and if so, what is the format and which DLLs to I need to reference in my program to get LEAD to recognize it?

Leadtools.dll version: 17.0.0.17

Thank you,

John Reichert

John,
The file appears to contain a group of JPEG images appended one after the other.

As a full file, this does not appear to be a common format. However, if you use our method RasterCodecs.Load(stream, offset, count), it should work.
For example, this code loads the first image in the file:
+------------+
System.IO.FileStream Fstream = new System.IO.FileStream(fileName, System.IO.FileMode.Open);
Fstream.Seek(0, System.IO.SeekOrigin.Begin);
RasterCodecs codecs = new RasterCodecs();
rasterImageViewer1.Image = codecs.Load(Fstream, 16, Fstream.Length - 16);
+------------+

To find other images, you can look for the JFIF image signature, which is hex "FF D8 FF E0".

Thanks,
Maen Badwan
