after updating to the new version of Aspose I noticed that the current RenderToGraphics, which we are using
slide.RenderToGraphics(false, graphics, width, height);
is marked as obsolete with the information that it will be removed with version 18.6
So I tried to change our code to the following and done a little profiling:
NotesCommentsLayoutingOptions options = new NotesCommentsLayoutingOptions();
options.CommentsPosition = CommentsPositions.None;
options.NotesPosition = NotesPositions.None;
Creating Thumbnails for every slide of a presentation with 140 slides only the first slide has content (one shape) all the others only have the title layout of the larissa master defined without content.
Old Method takes 25 seconds.
New Method takes 2:15 minutes
Szenario: Using a presentation of one of our customers which has 126 slides and 76MB of size and creating thumbnails for all slides. (Sorry I am unable to provide you with this presentation)
Old Method: takes 1 Minute and uses up to 300MB.
New Method: I aborted after 5 minutes and only 1/3 of the slides were done. The needed memory was up to 650MB.
Could you please take a look?
