The component has own renderer which supports DOCX format completely regarding ECMA-376 specification. Thus, now you have API to generate any complex DOCX documents from PDF without MS Office installed.

  • PDF to Word. We've changed the algorithm which scales width of symbols using the property KeepCharScaleAndSpacing. Thereby, this innovation increased the accuracity of PDF to Word converting.

  • PDF to Text. The speed of PDF to Text converting increased in a few times. This staggering improvement appeared because of new selective parser.

  • PDF to HTML. We've added two new properties InlineCSS and CombineImages. They gives you ability to produce inline CSS and combine all images on page into a single image.

  • Fixed some minor issues, which our customers sent to us. Thereby, the component became more error-free.


5.7.5.17 -
May 17th, 2016

We are happy to offer new PDF Focus .Net 5.7! Now let's get to know the core improvements:

  • Added new property ImageOptions.TiffCompressionType. It helps you to set compression type for Tiff images: CompressionLZW, CompressionCCITT3, CompressionCCITT4.

  • Added new property ImageOptions.RenderTextualData. With help of this property you may skip the rendering of all textual data during of converting PDF to Images.

  • In the PDF to XML and PDF to Excel converting directions added the vertical sorting of tables. Now they appear in the same order as they look in PDF.

  • Added new property HtmlOptions.ImageType. In a nutshell, now you can control the format for all images (PNG or JPEG) during PDF to HTML.

  • Added new property HtmlOptions.JpegQuality. It allows to specify the quality for output JPEG images from 1 to 100 (for PDF to HTML).

  • Added new properties HtmlOptions.SingleFontFamily and HtmlOptions.SingleFontSize. As their names implie, now you can set a new single font size and family for a whole text in the HTML document.

  • Fixed some minor issues, which our customers sent to us. Thereby the component became more error-free.


5.5.12.7 -
December 7th, 2015

We'd like to introduce the new PDF Focus .Net 5.5! Let's see the new improvements:

  • We've improved the algorithm to recognize tables in converting of PDF to Excel and XML. First and foremost, this helped to fix the issue with incorrect merging of columns during tables recognition.

  • PDF to HTML: Removed unnecessary duplication of tags <span>. This innovation allows to reduce the size of output HTML document and make it cleaner.

  • Added the new property OptimizeImages. It allows to significantly decrease size of output document because of minor losing of quality for all images. By way of example, we had a case where after the conversion PDF to RTF the resulting RTF became in 22 times less than without using of this feature.


5.4.5.20 -
May 20th, 2015

We are happy to inform about releasing new PDF Focus .Net 5.4! Let's see what we've prepared for you:

  • Added new feature: "Exract images from PDF". Starting from the version 5.4, the component can provide for your app various methods to extract raster images and transform vector graphics to raster images. Furthermore, you may specify to extract images only with a custom diapason of width and height. See new code samples: How to extract images from PDF in C# and VB .Net.

    PDF Focus .Net provides a full set of API to extract images from PDF

  • Regarding other features: we've made a lot of minor improvements to make the PDF conversion much precise and stable. For example, we've fixed the issue with changing dpi parameter during conversion PDF to grayscale and black-white images.

  • Added a lot of new code examples in C# and VB.Net: convert each PDF page to separate Word and HTML documents; extract Images from PDF.


5.3.3.16 -
March 16th, 2015

We'd like to introduce the new PDF Focus .Net 5.3! So, what's new:

  • Improved the processing of CID-fonts.
  • PDF to Excel: We've modernized the algorithm recognizing implicit columns.
  • PDF to Word: Improved rendering of text-shapes.
  • PDF to Jpeg: Added the new property «ImageOptions.JpegQuality».

    The "JPEG Quality" is a number that tells how much JPEG compression has been done. The "Quality" setting is kind of the opposite of the "Compression" setting, but it's just a different way of looking at the same thing. Higher JPEG Quality (or Lower JPEG Compression) gives you a better quality image, but it takes more disk space.  Lower JPEG Quality (higher JPEG Compression) lets you use less disk space, but your images aren't as nice and clear.

  • Added three overloaded methods Resize() to set custom image dimensions in pixels, points and percents. First and foremost, this feature would be useful when is necessary to generate images with fixed size in px. Let us say, to generate thumbnails 300x300px from a cover page of PDF documents.

  • Improved working with LZW decoding.

  • Fixed issue with converting of several special symbols, in particular: quarter and hyphen symbols.

  • Fixed issue with Regular style of Arial font.


3.0.2.20 -
February 20th, 2013

We are happy to offer new PDF Focus .Net 3.0! It's a really great breakthrough in the PDF conversion technology and we are proud to submit it.
Why is it so great?:

  • Maybe you know that PDF document doesn't have such expressions as paragraph, string, column, table etc. All text in any PDF document is located at (x,y) coordinates and tables is actually a set of graphic lines. Although typing a text in the MS Word editor is totally connected with using string, paragraphs and tables.

    Our developers worked hard several months to make an artificial intelligence which re-creates a Word document from a PDF like a typed by a human. A Word document produced by PDF Focus .Net now is completely editable and contains paragraphs, columns, tables, page breaks and so forth.

    Now PDF Focus .Net re-creates a Word document from a PDF document like it was been typed by a human.

  • Added ability to set mode for a resulting Word document: Flowing, Continuos and Exact. The "Flowing" is the most useful and common type of Word document for editing. The resulting Word document looks as if it was typed by human. The "Exact" is the mode when document layout created by using text boxes, this gives a monumental accuracy for PDF to Word conversion.

    Added ability to set mode for a resulting Word document: Flowing, Continuos and Exact.

  • A PDF document doesn't have real tables. If you see a table inside a PDF, in fact it's a set of graphics lines. Conversely, a lot of documents created in MS Word often have a lot of complex tables. Now the PDF Focus .Net can understand and recreate real-world tables with rows and cells from set of of orthogonal lines or text.

    PDF Focus .Net can understand and re-create real-world tables with rows and cells from set of of orthogonal lines or text.

  • Added support of underline and strike formatted text.
  • Added a new artificial intelligence system which converts some complex vector graphic elements (e.g. lines, curves, polygons) into a raster picture. This innovation significantly decreases a size of .doc file and time of its opening in MS Word.

    To reduce time of loading *.doc in MS Word we rasterized a complex vector graphics!

  • Added new ability to convert PDF documents into "1 bit Black & White" images. E.g., Convert a PDF to Black & White multi page-TIFF image. Thus, a resulted image will have a minimal possible size in kilobytes.

    PDF documents into "1 bit Black & White" images!

  • Created new code samples for VS2012, the assembly version compiled for .Net 4.5 and the Demo application for Windows 8.
