I’ve been doing a lot of work in the PDF space lately. While implementing Binary Cross Reference Streams I was surprised to see that they could be encoded with PNG Predictors. This was surprising to me because binary cross reference streams aren’t images, they are byte tables:
While the values vary, they are often within the ...

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 think the subject speaks for itself, but I'll ask anyway.
How do I implement PDF viewing on the clientside?
Thanks

Like the subject says, I'm trying to convert multipage TIFFs into searchable PDF's using the Expervision OCR engine. I tried the same code used in the GlyphReader example, but it only converts the first page of the TIFF. In other words, I get a single-page searchable PDF containing only the first image in the PDF.
So is there a ...

What product would I need to take a group of images and group them onto a page or pages of a pdf document?

I was trying to decode a bunch of pdf's into multi page Tiffs using DotImage 4.0h and the PDF rasteriser add-on, basically using code from this article (http://www.atalasoft.com/kb/article.aspx?id=10125&cNode=). It works great for over 80% of my sample pdfs, however there are a few which throw a 'DestSize must be greater than 0' exception on ...

A strange request, but something that I thought I'd share with you. Here is a simple console application that converts all pages in a hidden text behind image searchable PDF to a image-only non-searchable PDF. It requires that each page be in memory at once. If you have more than a few pages, you might want to save a temporary ...
