if you compare the output of the pdf that you generate from the code
and the pdf i attached (which was exported from ppt manually File->Export) you’ll notice that the resolutions are not the same. The emf images will be clean at each level as they are re-drawn. The raster image becomes pix-elated. I want to generate high resolution decks that are printable.
Zoom in to 400-800% on each pdf and compare the text on the images. I suspect that exporting from ppt embeds an emf file and saving as you instructed converts to some form of raster image.
I am looking at generating ppt with 100-400 slides which comes out to be 10-30mb ppt file. Using the export method on ppt generates a file that is 50-200mb in size.
I would like to know is it possible to save with the code you supplied to produce high quality pdfs (using emf) and the smaller size similar to the original ppt size.
