BARCODE
- New Micro QR-Code Reader & Writer engine.
- New Patch Code Reader engine.
- Improved 1D & 2D barcode detection speed (until to 2x faster) and accuracy.


IMAGE SUPPORT
- Added support to access image information, metadata and embedded thumbnail without decoding pixel.
- Faster JPEG codec (between 2x & 4x faster for loading and saving purpose).
- JBIG2 decoding: speed improvement, multipage reading optimization.
- Support for native 48-bit and 64-bit bitmap processing.
- Multipage tiff loading time divided by 2.
- Multipage tiff creation with mixed JPEG & CCITT compression support.
- Option added to extract a specific page of an editable multipage tiff document without the need to decode and re-encode the bitmap.
- Added support for sequential multipage tiff writing into stream objects (including mixed compression support).
- Added support to specify compression of each page in multipage tiff writing.
- Improved PNG encoder and added interlacing + compression level customization + 48 & 64 bit PNG creation + predictor support.
- Added RLE compression support for 8bpp BMP saving.
- Added 48 bit & 64 bit output support JPEG 2000 saving.
- Full ICC profile support for RGB and CMYK color spaces.
- Added transparency support for EXR saving.

OCR
- Create PDF/OCR from PDF keeping all input document content (fonts, text, bitmap, vectors, metadata, page structures...).
- GdPicture Tesseract Plugin is now based on Tesseract 3.02 and includes more languages.
- GdPicture Tesseract Plugin behaviour can now be fully customized.

PDF
- AES 256 bit encryption support.
- Average page rendering time decreased by 20%. Until 50% on bitmap based PDF.
- JPEG2000 compression scheme support for bitmamp encoding.
- Improved PDF parser to recover corrupted documents and to speed-up document reading / generation. 
- Added support for Adobe PPKLite digital signature applying. 


IMAGE PROCESSING
- Morphological Operators: Thinning, skeletonize, open, close.
- Native 16 bit per channel images filter support.
- Sobel and Prewitt Operators Edge Detectors filters.
