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

Hello Shervin,
PDF Clown is currently NOT compliant with PDF/A-1 (ISO 19005-1:2005) due to some features that haven't been implemented yet:
- device-independent colors (level B)
- XMP metadata (level B)
- Tagged PDF (level A)
Anyway, I want to progressively achieve the compliance.
Stefano.

Hi,
currently PDF Clown doesn't support font subsetting, so when you add a font to a PDF file you are embedding it *as a whole*.
Converting text outlines to graphic curves may be sometimes appropriate, but in my opinion it implies several drawbacks (impossibility to extract/manipulate text content, loss of rendering accuracy without font hinting, file bloating on long text documents...).

Hi Piotr,
unfortunately, special color spaces (as you can see here [1]) have currently a low implementation priority, so the best I can do at the moment is to suggest you some hints to accomplish your task.
PDF Clown's color space model is inside the it.stefanochizzolini.clown.documents.contents.colorSpaces namespace [2]; in accordance with the official PDF specification, there are 2 classes...

Hi Tobias,
I've just checked the 0.0.7 distribution content: I assure you that the *.properties files exist (I tested them for proper functioning on both GNU/Linux and MS Windows XP systems).
PDFClownSamples.properties is under "PDFClown/Java/samples/cli" path.
I suggest you to do a fresh new extraction from the distribution archive: maybe you inadvertently corrupted the extracted...

Hi Riccardo,
please note that, as Type entries in stream headers are NOT mandatory, using them to find relevant streams may be unsuccessful depending on the accuracy applied by the file generator. The most robust approach is to iterate through strictly-typed collections (such as page annotations, page resources etc.) in order to track them down. Accessing page annotations is a trivial...

Did you successfully converted the HelloWorldSample.cs *before* trying this one?
The TextExtractionSample.cs contains NO reference to Information class: what are you doing?
Please, be more specific or I won't be able to help you. :-)

User guide code examples are expressed in Java language; anyway, the translation to other languages is quite simple, as PDF Clown's API is the same for different platforms (there are just idiomatic differences, such as getters/setters, common standard interfaces like collections and maps and so on). For example, when you see the property getter file.getDocument(), its .NET version is simply...
