We've been running SSRS 2005 with Aspose.Slides v3 something for a while and all images have been resizing perfectly fine. We just upgraded to SSRS 2008 and the latest version of Aspose.Slides. Now all our images no longer resize correctly. The proportions are all weird (images are really thing but really tall). When looking into the powerpoint file, the scale on the size and position box would say something like "height: 28%, width: 10%" even when the lock aspect ratio box is checked.
Using SSRS 2005 with Aspose.Slides, images would say "height: 28%, width: 28%" and because of this, the images would look great with the proper proportions.
We are using an external image source for our images in the report. When switching to a database source, the images appear to look a little bit better (not as much out of proportion). It still has proportion issues though.
