Hi,

What do you think would be the best way to produce custom size image thumbnail from MS Office documents (doc, xls and ppt) on Windows with native code (means all means besides .NET/JAVA)?

My current research result:

  1. IExtractImage COM. Problem: The size of the generated result is fixed and low quality, and you can't be sure all the source documents contain the thumbnails.

  2. Use a programmable virtual printer to print the specified page, and the printer must support image output, any good suggestion for this?

What else would you suggest? thanks!
