Version 7.0 of the LEADTOOLS C API has changed from version 6.2 as follows:

You can now read and write progressive JPEG and LEAD CMP files.
You can now read, write, and play back animated GIF files.
You can now read and play back AVI files, and use them to create animated GIF files.
Other features of GIF files are now supported, including interlaced files, the full range of color resolutions, and the use of transparent colors.
When reading and writing TIFF files, you can now use the full range of palette indexes (1-8 bits per pixel).

You can now read and write Kodak FlashPix files.
You can now get and update information in a 16- or 32-bit file's alpha channel. This enables you to save a bitmap region in a file.
The BITMAPHANDLE, FILEINFO, and EXTFILEOPTION structures have been modified to support the new load, save, and animation capabilities.
Callback functions now provide more information to support progressive and interlaced formats.
Compression and decompression of CCITT Group 3 and Group 4, and LEAD 1-bit files is faster in Express editions.
