aspose.Slides is giving an error


I am using Aspose.Slides to convert ppt decks to jpg images. Im using jdk 1.5.08. The slide converter worked fine so far. However today I tried to convert a ppt deck and the converter would only convert first 11 slides out of the 25. On the 12th slide it gives the following msg and stops:

"Color parameter outside of expected range: Alpha"

This error message is not part of my java code but it coming from elsewhere. When I take the slide #12 out of the deck then the conversion works.

Could someone please tell me what could be causing this error.



When I get to the following section of code then the error occurs.

BufferedImage myImage = null;

myImage = mySlide.getThumbnail(dimension); <<<-this line causes the issue.

ImageIO.write(myImage, "jpg", aFile);

Hello Salman,

It looks like a bug in the Aspose.Slides.
Could you send me this presentation for testing please.
