As usual for 13 years now, the GdPicture.NET team strives to offer state of the art PDF support and document imaging technologies.
All major features have been improved: PDF, TWAIN acquisition, compression, document rendering, document conversion, barcode recognition, character recognition, and document clean-up.
A new document converter engine is available (GdPictureDocumentConverter class) and a new class is provided to bring advanced OCR support for document and fields recognition (GdPictureOCR).
This brand-new release also includes new or improved features for other popular document file formats, including Office Open Xml related capabilities and TIFF using Wang annotations. it also now support RTF, CUR and WSQ formats.
What’s new ?
New document viewer engine
This new version comes with a brand new and redesigned rendering engine permitting to render large bitmap very quickly, and display multipage documents in a multiple page view mode. It has been implemented into the WinForms version of the GdViewer control, for all supported Frameworks.
New document converter class
A new class to handle fast document conversion has been added to the toolkit. It permits to quickly convert any supported document format by GdPicture (more than 100) to popular formats such as PDF and TIFF, by handling every aspect of the conversion (color space, metadata, annotations, image, text…). (GdPicture Ultimate edition required).
New document segmentation class
A new class to segment document has been added to the toolkit. It permits to detect page layout (paragraphs / lines / words) or simply detect connected blobs on a bitmap. (GdPicture Ultimate edition required).
New supported document formats
RTF, DXF are now supported for viewing and conversion. Render & display, get thumbnail, browse, search, convert to PDF or bitmap…
View these documents within GdViewer & DocuVieware with multipage view mode, text search, text selection & extraction and more.
WSQ and ICO image files are also supported for viewing and conversion.
Optical Character recognition (OCR)
GdPicture.NET comes with a brand new class (GdPictureOCR) which includes near than 100 new features to better manage OCR processes. It provides segmentation features, support for OCRing any document to DOCX, HTML, PDF, and text files. It is now possible to process multiple regions of the same document very quickly with advanced support to control characters set, words association, voting mechanism, OCR mode, adaptive classification…
The OCR engine has been dramatically improved to reduce memory usage, enhance stability, and increase accuracy (especially with poor quality bitmap and very large bitmap).
There is also much improvement and bug fixes to better read Japanese, Hebrew, and Arabic text.
Searchable PDF Generation (PDF-OCR)
GdPicture.NET searchable PDF (PDF-OCR) creation has been improved. The creation is now faster and the produced files are smaller.
The character recognition engine has been optimized to use less memory, and the PDF page recognition method has been improved to avoid wasting time on existing visible text. Rotation detection and top of the art skew-detection have been implemented to permit OCR on any kind of oriented pages automatically.
Long term archiving (PDF/A)
PDF/A is an ISO standard for long-term archiving of electronic documents. Thanks to GdPicture.NET PDF/A capabilities, it is possible to create standardized electronic documents that can be rendered reliably over time on any system, when opened with a compliant viewer.
GdPicture.NET is able to generate any flavor of PDF/A: PDF/A -1a, PDF/A -1b, PDF/A -2a, PDF/A -2b, PDF/A -2u, PDF/A -3a, PDF/A -3b and PDF/A -3u.
Additional PDF support features
Most important parts of the PDF core have been enhanced to improve parsing, writing, rendering, memory usage and speed.
GdPicture.NET comes with a new font generation engine supporting subsetting of True Type fonts when writing PDF with Unicode content. The software now supports OpenType font for Unicode text drawing. The new text extraction algorithm builds text closer to the natural reading order.
GdPicture.NET is now up to 5 times faster reading a complex PDF and dramatically faster writing pdf text. GdPicture.NET produces smaller file and the compatibility with several viewers has been improved.
Other new features and enhancements include:
- Support for transfer functions to the PDF rasterizer.
- Added support for applying digital signature with Timestamp.
- New CCITT filter decoder.
- Support for adding JPEG image to PDF without decoding / re-encoding the image.
- Improved speed of the PDF rasterizer for jbig2 bitmap.

Office Open Xml Word Processing Document
GdPicture.NET includes a lot of improvements of the rendering engine and provides support for tables content and pictures. The rendering engine is up to 80% faster.
Dramatically improved MICR engine accuracy and speed for CMC7 and E13B fonts. Improved check reader engine.
MRC Compression engine
Dramatically improved the MRC engine to produce smaller and better quality PDFs. Read more.
The GdPicture.NET barcode reading engines use an error correction mechanism which makes the reading robust to noise caused by low image quality. An improved error correction mechanism has been introduced within GdPicture.NET to improve the speed and accuracy of the engines.
Barcodes use finder pattern to locate the code within a document. The processing of the finder pattern has been fine tuned to improve the speed and the barcode coordinates retrieved by the engines.
The following figures have been obtained when comparing GdPicture.NET engines to GdPicture.NET 12.0 engines on a wide collection of documents:
- 1D barcode reading engine
- 10% more barcodes recognized
- 44% more patch codes recognized
- 14% faster
- Data matrix barcode reading engine
- 15% more barcodes recognized
- PDF 417 reading engine
- 14% more barcodes recognized
- 40% faster
- QR code reading engine
- 18% faster
- 24% more barcodes recognized
Document Imaging Filters
- GdPicture.NET page auto-deskew accuracy has been improved. A better correction of the skew introduced when making use of an automatic document feeder during the scan improves the legibility of the document (together with the character recognition accuracy).
- The accuracy of the blank page detection engine has been dramatically improved to better sort empty pages, to handle punch holes and margins. It can also now be applied on specific region of interest.
- Added support for region of interest to the blank page detection algorithm.
- The blank page detection engine can now identify margins and punch holes.
- Introduced a new color dropout filter to drop a specific color into several contexts: drop out forms, etc..
