How to compress and pack existing PDF

Post by Loïc » Sat Dec 24, 2011 12:42 pm

Hello,

Here a simple example demonstrating how to configure the GdPicturePDF class for compression & packing.

This is quite simple, stable & fast... What else ? :)


Code: Select all

            GdPicturePDF oGdPicturePDF = new GdPicturePDF();
            oGdPicturePDF.LoadFromFile(@"c:\input.pdf", false);
            oGdPicturePDF.EnableCompression(true);
            oGdPicturePDF.SaveToFile(@"c:\compressed.pdf", false);
            oGdPicturePDF.SaveToFile(@"c:\compressed_pack.pdf", true);
            oGdPicturePDF.EnableCompression(false);
            oGdPicturePDF.SaveToFile(@"c:\uncompressed.pdf", false);
            oGdPicturePDF.SaveToFile(@"c:\uncompressed_pack.pdf", true);
            oGdPicturePDF.CloseDocument();

Hi Loic-

This is handy, but how does one control the type and amount of compression applied by this method?

Thanks,
Leo

Hello Leo,

What do you mean by "type and amount of compression applied " ?

Kind regards,

Loïc

Hi Loic-

Various types of compression (the best example being jpeg) allow for various trade-offs between compression and quality of image. The code you provided does not address which compression type will be applied (jpeg, jpeg2000 etc) or the quality level. Does it rely on defaults? If so which ones?

Thanks,
Leo

Hello,

Does GdPicture (v10 or 11) support MRC compression please ?

Thank you,
Mickael Vest.
