DataMatrix problem
12.png Hi- I have created a Datamatrix decoder (in the code section below) but it fails to recognize a single barcode. Am I doing something foolish? All I get is "No barcode detected!" Source file is attached, plus a parsed out subimage which also fails with my code and the example barcod...

Re: OCR Failing
Hi Loic- Thanks for the suggestion. I added : gdpStat = oGdPictureImaging.GetStat() after the PdfAddGdPictureImageToPdfOCR statement. For each page the returned value is 0 (OK)! However, there is still no text added. :( If I move the dictionary file I get status 801 (OCRDictionaryNotFound), which is...

Re: How to compress and pack existing PDF
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 on...

Re: How to compress and pack existing PDF
Hi Loic-
This is handy, but how does one control the type and amount of compression applied by this method?
Thanks,
Leo

Re: Document sizes after PdfAddGdPictureImageToPdfOCR
Hi Loic- Thanks for the suggestion, but that does not help. I already had a select/case statement to do conversion back to the original bit depth (though the RenderPageToGdPictureImageEx method is a better way). I still have this 11k input pdf coming out as 1148k!!! Is it possible that the JPEG comp...

Document sizes after PdfAddGdPictureImageToPdfOCR
Hi- My application executed OCR on scanned image PDFs to create searchable PDF/A output. However, I have noticed that the result of the code below takes as much as 10x disk space as the original. Can anyone explain why? Am I missing a step somewhere? Attached is a sample PDF that goes from 12k befor...

PdfAddGdPictureImageToPdfOCR and Timeout
Hi- Is it possible to set a timeout for this function (PdfAddGdPictureImageToPdfOCR). I am having periodic issues with this call simply running forever (>1 hour) on relatively small image PDFs (e.g. 40 pages). Since I am not able to figure out what is wrong with these PDFs I would like to be able to...
Huge PDFs
Hi- I'm trying to open a 10 page pdf that takes up 740MB on disk. GdPicture seems to fail no matter how I try to do it. Is this simply too large a file for GdPicture? Also, given that the pages (when I output them each as a tif using Acrobat8) are only 3000x4000 pixels, any ideas what else could be ...
