Subject Re: Problems with images in XLS templates files using POI.
Date Thu, 05 May 2005 18:38:55 GMT
I had a problem with image size. If it's a huge image in the template,
the generated file gets corrupted. I tried with a smaller logo and it
worked fine. I haven't researched why this happens. And I may be
entirely wrong on the image size as well. But you could try reducing
the size of the logo.
