Changes from Version 8.0 to Version 9.0

Version 9.0 of the LEADTOOLS C API has changed from version 8.0 as follows:

LTKRN90N.DLL and LTKRN90W.DLL have each been split in two. The new DLLs are LTKRN90N.DLL and LTDIS90N.DLL, and LTKRN90W.DLL and LTDIS90W.DLL. All programs that display images will have to use the appropriate LTDIS90 .DLL file in their projects.
Reusable dialogs for the most common LEADTOOLS imaging functions are now provided.
FileOpen and FileSave dialogs have been extended to contain LEADTOOLS specific options.
A Thumbnail Preview option for FileOpen dialog allows the end user to preview images before loading them.
A Thumbnail Preview option for the image processing dialogs allows the end user to preview the proposed change to the image, before actually affecting the original image.
An optional Help Button callback function lets you provide custom help information for each dialog.
A user interface control for the dialogs is provided through flags passed to each dialog function.
An option to have the Imaging Common Dialog process the image automatically is provided.
Now you have more control over the loading and caching of the file filter DLLs.
Now you save more than one custom TIFF tag.
Now you can load only a specified portion of an image file.
[Express editions] Support for ISIS scanning has been added.
[Express editions only] New functions allow you to hyperlink annotations. Annotations may be hyperlinked to run a program, access a Web page, or send a user defined message.
[Express editions only] New annotation functions allow you to add security to annotation objects.
[Express editions only] New annotation functions allow you to create hilite objects.
[Express editions only] New annotation functions allow you to set bitmap stamps to be transparent.
[Express editions only] Support for 12 and 16-bit grayscale images is included.
[Express editions only] New window leveling functions for 12 and 16-bit grayscale allow you to map grayscale intensities by specifying the bit range and/or a user defined color map. It is valid only for 12 and 16-bit grayscale images.
[Express editions only] Support for annotations in a TIFF tag is included.
[Express editions only] The automated mode for annotation lets you move individual points in a polygon or a polyline.
