Is there any chance that when the image stream is big, there is some kind of access problem via the reference table to the icc object (byte count too big...or other?). I noticed it always written after the image stream.
BTW have you got the PDF file I sent you? Thanks Jonathan -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Wednesday, September 26, 2007 9:09 AM To: [email protected]; Jonathan Sibony Subject: Re: [Podofo-users] ICC Profile support Hi, Hmmm, I can't see why the size of the image should matter for the ICC profile. Maybe something simple like the larger image being CMYK and the smaller one being RGB? Can you create a fresh PDF with Photoshop and embedd the ICC there and compare the results to the PDF created by PoDoFo? (PoDoFoBrowser/podofouncompress are your friends for task like these). Otherwise: Could you upload the PDF (or another example) somewhere so that I can try the PDF myself? I guess it is to large to be sent by email. best regards, Dom Am Tuesday 25 September 2007 schrieb Jonathan Sibony: > Hmmm I guess it was too early to celebrate. > > It seems that for small files (1x1 inch 72 dpi)all goes well (when > opening the file in photoshop, a dialog pops asking whether to use the > attached profile). > As to larger files (10x10 inch with 720 dpi) a different dialog is > issued asking the image dimensions and the requested resolution (should > be dictated automatically from the pdf as in small files) and profile is > not mentioned, instead default profile is used), when given it goes > rasterizing. > > Any clue? > > joanthan > > > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] > Sent: Sunday, September 16, 2007 7:17 PM > To: [email protected]; Jonathan Sibony > Subject: Re: [Podofo-users] ICC Profile support > > Great that it works now! > > Could you please send me your code for ICC support or provide a patch > for > PoDoFo so that other users can also profit from this addition? > > best regards, > Dom > > Am Sunday 16 September 2007 schrieb Jonathan Sibony: > > I changed it a bit and it works!
