Changes from Version 8.0 to Version 9.0

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

$image\sqrblit.gif$ 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.

$image\sqrblit.gif$ 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.
