We have published Docotic.Pdf 5.1 on our site and on NuGet.
The new version comes with brand new JPEG 2000 codec. The codec is much better than the one we had in previous versions of the library. The decoder part of the new codec allowed us to fix some nasty bugs which affected drawing of documents with particular JPEG 2000 images.
The good news is we now have encoder part in our JPEG 2000 codec, too. We added PdfImage.RecompressWithJpeg2000() methods, so you can recompress images using JPEG 2000 compression either lossless or using specified conversion ratio. You can also recompress images with JPEG 2000 when adding them to document. PdfImageCompression.Jpeg2000 is now properly supported in such a use case.
Just as some of our customers asked, we added custom exception classes for specific error groups. All the new exception classes are descendants of the PdfException class, so the change is not a breaking one. Here is the list of the new classes: CannotDecryptPdfException, CannotParseFdfException, CannotShowTextException, IncorrectPasswordException, UnexpectedStructureException, UnsupportedFontException, UnsupportedImageException, UnsupportedMetadataException.
In Docotic.Pdf 5.1 we added ability to draw whole PDF document to multipage TIFF image. The PdfDocument.SaveAsTiff() methods produce one TIFF from all pages of a PDF document. The produced TIFF will consist of multiple pages (frames).
With the latest version you can extract visible text only. Please take a look at the new PdfTextExtractionOptions.SkipInvisibleText property. Use PdfDocument.GetText(PdfTextExtractionOptions) or PdfPage.GetText(PdfTextExtractionOptions) methods to extract visible text only.
There are other changes. Read about all new features and improvements in Docotic.Pdf 5.1 in the Version History document.
We have just released Docotic.Pdf 5.0.
This release includes version for .NET Standard Library 1.3. So, starting from 5.0, Docotic.Pdf can be used in .NET Core and Universal Windows Platform apps and services. This is in addition to .NET 2 and later frameworks, of course.
Our customers asked us to add the ability to extract vector paths from documents. And here it is. By the way, you can extract clip regions, too. Take a look at the Extract text, paths and images sample to get an idea about how it works.
Version 5 adds ability to open and create PDF documents encrypted with AES-256. This should come in handy if you need stronger security algorithms in your workflow.
We also fixed number of issues related to drawing and extraction of images. And as always, text extraction was also improved.

I am pleased to announce that Docotic.Pdf 4.9 is out on our site and on NuGet.
In the latest version we added support for layers (also known as optional content groups). The library can now create layers, enumerate existing layers, add widgets, controls and XObjects to layers. Check the Layers group of samples for some examples of what was added.
Starting from Docotic.Pdf 4.9 the library can draw documents with soft masks properly. And we also improved support for blend modes and transparency groups. By the way, the new version can also remove transparency groups from PDF documents. This feature is important if you are converting existing documents to PDF/A.
We significantly improved forms handling in the library. The library does better job in parsing of controls and their associated actions. We fixed issues related to drawing of forms and changing properties of existing controls. And we didn’t miss opportunity to fix some bugs in form filling and flattening.
There are number of fixes for text extraction and drawing. They include fixes for vertically written, stroked or rotated text.
We also fixed images-related issues. The new version handles JPEG, JBIG2 and PNG images (including images in CMYK color space) better.
There are quite a lot of other changes. Read about all new features and improvements in Docotic.Pdf 4.9 in the Version History document.
We released new version of Docotic.Pdf library on our site and on NuGet.
This version adds ability to flatten PDF forms. Flattening locks controls from editing. Flattening can significantly reduce file size if the document is then saved with PdfSaveOptions.RemoveUnusedObjects option set to true. To flatten form fields in a PDF file please use PdfDocument.FlattenControls() method.
We also added support for list boxes (there is Listboxes sample illustrating how to create them). The PdfCheckbox got new ExportValue property. You can use this property to extract export value of a checkbox.
Docotic.Pdf 4.8 fixes number of issues related to processing of controls and widgets. The new version parses, draws and fills PDF forms better than before.
The new version fixes some issues related to extraction of JPEG and CCITT (Fax) images. Text drawing and text extraction also got better. And the library is now more prepared to work with not completely correct PDFs.

We released new version of Docotic.Pdf library on our site and on NuGet.
The new version adds ability to specify the place where library should keep its intermediate data. You can tell the library to keep all the data in memory or to keep smaller streams in memory and other streams in temporary files. The latter is the default option. You can create your own stream provider and tell the library to use it. You can read more about this in documentation for IPdfStreamProvider interface and PdfConfigurationOptions class.
We fixed a number of issues related to image processing. The library now draws and extracts images better, spends less memory to recompress them and more prepared to handle not exactly correct images.
Docotic.Pdf 4.7 fixes some text related issues and, thanks to some of our customers, we were able to improve support for CJK text drawing and extraction.
This version also better draws documents with transparency groups and documents which use blend modes.
And as always, we improved the library so it can work with more of those not completely correct PDFs created by unknown generators.

The new version of the Docotic.Pdf library got published on our site and on NuGet.
Substantial amount of improvements in Docotic.Pdf 4.6 is related to memory management. Latest version uses much less memory to open or draw PDF documents. Extraction of JPEG 2000 and JBIG2 images also uses less memory in Docotic.Pdf 4.6.
The new version also contains improvements to text extraction, text rendering and font processing features. Version 4.6 handles Japanese text better than any previous version.
We also dedicated some time to rendering features of the library. The latest release draws text, patterns, XObjects, and forms better. Just better.

The new version of the Docotic.Pdf library is available on our site and on NuGet.
Docotic.Pdf 4.5 extracts and draws images faster. Especially, images with masks. The new version also processes Type 0 fonts faster.
As usual, there is a number of bug fixes in version 4.5. Most of the bugs affected quality of PDF rendering, so now library draws PDFs correct in more cases than before. Also as usual, the new version improves support for semi-broken PDFs created by some buggy and usually anonymous generators.

We released Docotic.Pdf 4.4 on our site and on our NuGet channels.
The newest release of the library brings improvements to rasterizer, content extractor and parser parts.
The version 4.4 is more robust in parsing of semi-broken PDFs created by some buggy generators. At the same time, in this version we fixed some of our own bugs related to parsing of fonts, content streams, forms, and functions. As the result, Docotic.Pdf 4.4 draws and extracts text more precisely. It also processes colors of images, text and graphics better than before.
With the new version it’s possible to access log messages emitted by the library. The library now uses log4net for logging purposes. Place an XML configuration file next to the library if you want to access these messages.
There are other improvements and bug fixes. Read about all new features and improvements in Docotic.Pdf 4.4 in the Version History document.
We have released Docotic.Pdf 4.3.
Starting from this release the library ships in two versions. One version is for NET 4 and later frameworks and the other one for .NET 2 and later frameworks. So, now you can benefit from the version built for .NET 4 while you are still able to use the library in projects targeting older .NET frameworks.
Docotic.Pdf 4.3 brings support for Type 3 fonts. This version also contains number of other improvements related to fonts.
The library now can stroke and fill paths with patterns. This is a relatively rare feature of PDF format but it really shows when you try to draw document with patterns and there is no support for drawing them.
The new version adds support for PDF functions, separation color spaces and spot colors. We also fixed some issues in color processing.
We also improved extraction of text and images. These are some of the areas we improve in almost every version of the library. This is release is not an exception.
There are other improvements and bug fixes. Read about all new features and improvements in Docotic.Pdf 4.3 in the Version History document.
We encourage you to download and try the new version.
In the first part, we have completed the basic PDF printing application. The “Hello World” sample is good as a proof of concept, but it is too simple. You will probably want to have following features in a real application:
I will incrementally modify the demo application in order to show how to support all of these features.Read More
