I'm using the Atalosoft DotImage 5.0 product.  We have images stored in a SQL Server DB.  We have a .net 2003 app that pulls these images, loads them into a byte array and then into a memory stream.  We then attempt to open this stream in order to display the pdf using the Workspaceviewer control, but when the ...

The PdfTextDocument class is for text extraction only.  As of DotImage 7.0 it is not possible to modify discrete properties of existing PDF files with our toolkit. 

If I have to import PDFs into a document management application, what's the best way to handle OCR? Some PDFs are already searchable, some aren't. How do I check? Just see if there's any text? Can I turn a non-searchable PDF to a searchable PDF in the same way that I would turn an image into a searchable PDF?   Cheers,   BF

When creating searchable PDFs from images, temp files with names like tmp23.pdf appear in the same folder as the image file. This only appears to be a problem on XP. Is this a known issue? We're using 6.0d   Cheers,   Bob

Hi, not sure if this is a DotAnnotate or a DotImage question. I'm creating a PDF Document viewer based on the Atalasoft.Imaging.WinControls.DocumentViewer control. I've added a search box so a user can search through the text, but I need to add 2 types of highlighting to the viewer and am struggling to do it. Firstly, when a user enters ...

I use the following code to convert a PDF to a TIF image. This works fine for the majority of the files -- however, ocassionally, one of the TIFs will be returned as completely black. Any idea what is going on?   Dim pdf As PdfDecoder = New PdfDecoder() pdf.Resolution = 150 RegisteredDecoders.Decoders.Add(pdf) Dim myWorkspace As ...

I need a little claification on pdfs. We work will 1bit scanned images and our customers want pdfs Converting back and forth between the formats, gray scale and black and white, the images get blurry so we think creating/extracting might be the way to go. 1) will singleimage=true if the pdf page is a single image AND contains ocr info? 2) does ...

I am using the folderThumbnailView control in my app and I also have the Atalasoft PDFRasterizer - my question is: how can I make the thumbnailviewer show PDF images - I have added the .pdf extension to the filter property but still no joy. Please help. Thankyou.

Try increasing the resololution in the PdfDecoder object.  The blur might be from rasterizing it at a lower resolution, then zooming in.

DotImage PDFRasterizer will extract the embedded image and resample the image based on the requested resolution when singleimage=true.  If the original image was bitonal, the result when rasterizing is likely to be grayscale due to resampling.  Depending on what you need, you might want to extract the image yourself when ...
