Hi,

I have a requirement of converting thumbnail images into a ppt slide using Aspose.slides for Java. Can this be done using Aspose? Please confirm as I need to work on the requirement and determine the results ASAP. Thanks in advance.

Dear waves

Aspose.Slides let you add any picture/image on slide. You should add your thumbnail image as a PictureFrame. To see, how to add a PictureFrame, please see this link.

Hi,

Thanks for the information. I am using the code snippet you provided but I am facing two problems:

Picture pic = new com.aspose.slides.Picture(pres, iStream);

In the above line, I get a compilation error stating that Picture object type is ambiguous.

Secondly, in the below line of code, I get a compilation error stating that

RenderedOp and JAI cannot be resolved.

RenderedOp img1 = JAI.create("fileload", "C:\\demo.jpg");

Am I missing anything in the above line of code?

Please help me out with these issues. Thanks a lot in advance.

I have commented the lines which are giving you error, actually, you don't need them. Try running the same code with little modifications by me.

I have attached this code, also the output presentation and source image used in it.
