Get the thumbnail of a PDF as an image

Hi - How can I extract the thumbnail of the first page in an existing PDF file in my Windows Visual C++ application as a JPEG, PNG or TIFF? - If possible I don't want to use the Acrobat SDK. Is there another library available to do this? I have to do that in a Windows C++ application and eventually in a MAC OS X application (Codewarrior; MACH-O). Thanks Hans

Hi Thanks for the fast answer. I mean the embedded thumbnail (if possible). I want to extract this one as a JPEG, PNG or TIFF. How can I do that? If I see that the quality is too low, I want to render a new thumbnail. But first I want to test the embedded one. Thanks again.

There are no specific functions to do this (because it is such a useless, poor thumbnail). To do this you would want an API that gave low level access to the raw objects in a PDF. You would then retrieve individual Thumbnail Images (see chapter 8.2.3). This would be an image XObject in one of a number of color spaces, you would have to convert this manually to your required bitmap format. ---------------------------------------- Aandi Inston quite@dial.pipex.com http://www.quite.com Please support usenet!

Hi Hans, Amongst the many features offered PDF-Tools SDK allows you retrieve a pages thumbnail and save to a Raster format as required - you can obviously replace should you require to do so. I suspect you would need to be doing more than just this with the library to justify the purchase price ($499) - but then there are a host of useful features - so it should not be hard to find something with the functionality to make it worthwhile. There is a fully functional evaluation (no time out) of our complete PDF Library and driver SDK available from : http://www.docu-track.com/home/dev_tools/ The SDK is of course distributable Royalty Free once licensed. -- Best Regards John Verbeeten Tracker Software Products PDF-XChange & SDK, Image-XChange SDK, PDF-Tools & SDK, TIFF-XChange & SDK, DocuTrack.

Hi John Thanks for the information. At the moment I have only to extract the thumbnail, nothing else. You mean I use a Single-User license for developing and can ship the library or dll to our clients with my application? Thanks again.

Hi John I have tried the sample ThumNails. But I can't test it because the dll xcpor30.dll fails. What can I do? Or how can I extract the thumbnails of a pdf?

Hi Hans, If you purchase the SDK - you can indeed distribute the require DLL's with your app Royalty free. I'll get the demo checked as XCPRO30 has been superseded by the XCPRO35.dll and help file - could you please advise which of the demo app's you tried ?

Hi I have tested the sample \Examples\SDKExamples\CExamples\ThumNails. Meanwhile I have changed to the newest SDK 3.5 instead of the SDK 3. But I haven't a thumbnail in my PDF so I can't export is as a bitmap. Other question: Is it possible to export the first page of an existing PDF as JPEG, PNG or TIFF? How can I do that?

Hi Hans, Thanks for the info about the demo app - I will have this redundant demo removed and replaced as necessary. Obviously if the thumbnail is not there - it cannot be extract and I am afraid we do not at this time offer a means to make one. However - our own PDF viewer is currently in beta prior to release and once the developer kit for this is released - we will provide a means to create thumbnail and add it to the file. -- Best Regards John Verbeeten Tracker Software Products PDF-XChange & SDK, Image-XChange SDK, PDF-Tools & SDK, TIFF-XChange & SDK, DocuTrack.

Hi Hans, you can currently extract image content from a page to any of the Raster Image formats supported - if they are in fact images, but you cannot extract non image content to an image file (i.e. Text etc). But - as stated - once our viewer is released in the coming weeks - this too will be supported, you will be able to convert pages/files etc to image content and extract to any of the supported Raster formats. For your info : PDFXCp_GetImageFromPage is detailed in the help file XCPRO35.CHM The IMG_- functions are detailed in the help for our Imaging Library (Image-XChange which is a separate download) - a limited number of these functions are accessible (and allowed) from the PDF libraries to assist in Image related functionality HTH -- Best Regards John Verbeeten Tracker Software Products PDF-XChange & SDK, Image-XChange SDK, PDF-Tools & SDK, TIFF-XChange & SDK, DocuTrack.

Hi, On Tue, 16 May 2006 13:14:13 +0200 "Hans Stoessel" <hstoessel.list@pm-medici.ch> wrote: > Other question: Is it possible to export the first page of an > existing PDF as JPEG, PNG or TIFF? How can I do that? raster it. If you want free utilities, check out Ghostscript or Xpdf/poppler (e.g. pdftopnm). If you want to embed into C++ code, I'd suggest the poppler library, should work right out of the box. Use libpng/libtiff/libjpeg for conversion into the formats you've mentioned, poppler will only give uncompressed raw pages. I don't know about commercial ones here, most I've seen use one of the mentioned free utilities internally. -hwh
