My originally 128622 bytes document is growing on 140746 plus it is broken.
If CompressImages = true or RemoveUnusedStreams = true file will be damaged.
Sample project is attached.
Btw. If I use www.ilovepdf.com to compress the same file (I am selecting their recommended settings) file size is reduced to 62kb (file: Helia 44-ilovepdf-compressed (1).pdf is attached). If I choose extreme compression they are reducing size to 48Kb (attached file: Helia 44-ilovepdf-compressed (2).pdf).
From forum I saw that you had more than few people having PDF compression issue so would be great to make some breakthrough here :)
Btw. Big compression I saw when I set UnembedFonts=true but this will ruin document formatting as some default font is used.
Also when I compare with documents compressed by ilovepdf.com I see that in original document I had 6 embedded fonts (1x ArialMT, 3x Helvetica, 2x Helvetica-Bold). Can you extend Aspose.PDF to remove duplicated fonts but also unsed fonts? That will certainly help in this case.
