Available in LEADTOOLS Imaging Pro, Vector, Document, and Medical Imaging toolkits. |
Version 16.5 of the LEADTOOLS C++ Class Library 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 now supports the following file formats:
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 has enhanced the following File format support to improve performance:
Raster
PSD (PhotoShop 3.0): Now adds support for reading channels from PSD files.
FIT (FITS Format): Enhances the support of dealing with multidimensional files by considering the two dimensions only.
