Hi all. First of all, a massive thank you to Stefano for what is a brilliant API. It's saved me endless heartache trying to mash together this app I'm working on.
I'm trying to layout some text in columns. The width of each column and the allowed height are known variables and the text must flow from one column to the next correctly. This works fine.
However, now I have started adding...

I am using the .Net/C# implementation of PDFClown. I am having trouble setting the value of a checkbox, while textfields save just fine. I have tried many variations of getting the checkbox value to change and here is my latest attempt. Does anyone have any experience getting this to work?...

Hi Don,
this behavior currently happens when you try to open a PDF file whose *cross-reference information is stored in a **cross-reference stream*** [PDF:1.6:3.4.7] *instead of in a cross-reference table*, because it hasn't been implemented yet.
As I've already received other requests on this topic, I scheduled it possibly for the next release.
Stefano.

Hi
in the downloadable distribution of PDF Clown you can find ImageExtractionSample which lets you discover the images contained by a PDF file and extract their data stream.
Then you can either substitute the content of the stream body buffer (see the above-mentioned source code) updating its dictionary to accomodate changed parameters, or substitute the whole old stream instantiating a new...

Hi,
I actually work on a content capture application, which scan papers or press articles, apply an OCR on it and then generate a pdf with the original image and the extracted text on an underlevel layer.
The problem is that for OCR be effective, i need a "huge" resolution, saying 300 DPI. But, the goal of this system is to provide documentation to user on a local network, and i...

Well the pdfrendere realized that the text is italic and the picture loses a bit of quality.
jpedal already has a demo version but limited to 10 pages.
you have another recommendation:
tks!

Hi Ayres,
I'm sorry, but PDF Clown doesn't provide a pdf viewer.
Please try something like PDF Renderer [1] or JPedal [2].
