Topic: Multiple Filters + JPEG Quality ?

Hello Everybody,

I am having a bunch of PDF which will have images with either of these compressions applied [LZW+DCT],[ZIP + DCT] or just DCT.
My client wants a plug-in that shows them just the -DCTDecode Quality Factor. I am making use of the DCTDecode DQT to find the quality factor when its a single filter.

My problem is , how do i get only the DCTDecode image data stream when there is multiple filters.
For single filter i used 'CosStreamOpenStm' and the cosOpenUnfiltered options. How do i get just the DCTDecoded stream when there is multiple filters Eg: [LZW+DCTDecode].

Thanks In Advance,
Warm Regards,
Shine Vijayan
