Changes from Version 16 to Version 16.5 (original) (raw)

Version 16.5 of the LEADTOOLS C API has changed from version 16 as follows:

LEADTOOLS is now built using Microsoft Visual Studio 2008, and requires the VS 2008 C/C++ runtime. All Visual Studio example projects included with LEADTOOLS are for VS 2008. If you require VS 2005 example projects, please contact Tech Support.
LEADTOOLS Document Writers, provides programming tools for creating popular multipage and searchable documents such as Adobe PDF, Microsoft Word and HTML from standard Windows Enhanced Meta File (EMF) objects.
LEADTOOLS Virtual Printer Driver, which allows you:
- Capture print jobs from any Windows application as EMF.
- Programmatically install and un-install virtual printers to a target system.
- Control access to the printer by locking it for use only by your application.
- Configure the virtual printer to start your application when a print job is received.

For more Information, refer to Working with the LEADTOOLS Virtual Printer Driver.

LEADTOOLS now supports the fast magic wand feature.
LEADTOOLS now supports the following file formats:
- XPS (Microsoft XML Paper Specification)
- IM1 (AFP Image Objects)
- TDB (Thumbnail Database File Format)
- TDB Vista (Thumbnail Database File Format for Windows Vista)
- SNP (Snap Shot File Format)
LEADTOOLS now supports TWAIN 64 bit.
LEADTOOLS includes JPEG2000 and JPEG support enhancements to improve performance compared to version 16.0 as follows:
- JPEG2000 lossy decoder is 300% faster.
- JPEG2000 lossless decoder is 10% faster.
- JPEG2000 decoder uses MMX/SSD instructions by default. [To disable this feature and use floating point arithmetic, use either LOADFILEOPTION::Flags ELO_DISABLEP3 or LOADFILEOPTION::Flags = ELO_DISABLEMMX flags.]
- JPEG lossless encoder and decoder are about 300% faster for RGB24 bitmaps.
- JPEG lossless encoder and decoder are about 25 - 50% faster for Gray 8-, 12- and 16-bit bitmaps.
LEADTOOLS now supports graycolor custom painting.
LEADTOOLS is deprecating the SID file format.
LEADTOOLS now supports rake removal that removes the rakes from the 1-bit images.
LEADTOOLS now supports invert page that detects whether the image is inverted or not.
LEADTOOLS now supports high quality rotate that rotates the 1-bit image without corrupting it.
LEADTOOLS now supports tissue equalize that enhances the medical image by amplifying the features of the medical images.
LEADTOOLS now supports object counter that counts the number of objects inside the image.
LEADTOOLS now supports sigma filter that reduces the noise.
LEADTOOLS now supports auto-zoning that detects the different zones in the image.

LEADTOOLS has enhanced the following File format support to improve performance:
