I try to convert the image below with a command like this:

 "C:\Programme\Microsoft Corporation\Deep Zoom Composer\ImageTool.exe" convert "C:\153.jpg" outdir "C:\test" jpg tilesize 256 tileoverlap 1

Command output is:

 Error: unknown pixel format

 After a view hours of testing I realized that the image format is 8 bit grayscale. I think this should work anyhow.

Hi,

On the face of the error, it seems related to the image's format.

Does it work now?

 Hi,

Unfortunately not. I have to convert each grayscale image to a true color (24-bit) one.

Regards,
