Re: Use multiple scanners simultaneously

Hello, You can use only one device per one GdPictureImaging object because you need to select/open the required device/source: TwainOpenSource TwainSelectSource So I would say using multiple GdPictureImaging objects you can open more devices. You can also check our Twain Scanning – Asynchronous Samp...

Re: OCR on TIF coverted from PDF

Hi,

Finally, we have figured out that the source PDF has internal page rotation. After solving this with the use of NormalizePage() method the OCR results are excellent and there is no need to convert to TIFF.
So maybe this helps also to others.

Re: OCR on TIF coverted from PDF

Hello, I would like to explain to you here some more details about OCR. From what I see, you saved the scanned pages in PDF document. Using GdPictureOCR class you will need the scanned image, so here I would recommend you to scan directly to tiff. Next, you need to scan using appropriate DPI, so the...

Re: Why there is no image compression for GIF, JPEG, PNG image

Hi, The JPG, PNG, GIF formats are others than TIFF. The toolkit opens jpg/png/gif formatted files into a bitmap. Once they are opened, there is no information about the used compression available. And actually, it is not needed, as you should next save the images always defining the required compres...

Re: Tif image CreateAnchorTemplate and FindAnchor issue with DPI

Hi, The only possible solution here is that your template and all candidates need to have the same characteristics so the results are consistent. That means if the template is 300 DPI then the candidates should also be 300 DPI with the same kind of acquisition context. Of course, you can re-scale th...
