Changes from Version 12 to Version 12.1

Version 12.1 of the LEADTOOLS ActiveX has changed from version 12 as follows:

LEADTOOLS now supports the J2K and JP2 JPEG 2000 file formats. (JPEG 2000 Plug In only)
Please note that the vector file format support previously provided by the LEADTOOLS File Format Plug ins is now provided through the LEADTOOLS Vector View Plug in. Therefore, the L_SUPPORT_VECTOR_DWG, L_SUPPORT_VECTOR_DWF, L_SUPPORT_VECTOR_DXF, L_SUPPORT_VECTOR_MISC and L_SUPPORT_VECTOR_ALL constants are now obsolete. If these constants are currently in your code, they will continue to work in LEADTOOLS 12.1. However, you should consider adding the LEADTOOLS Vector View Plug in or upgrading to the LEADTOOLS Vector Imaging Pro toolkit.
Vector support can now be unlocked for viewing only. Please note that if vector viewing support is unlocked using L_SUPPORT_VECTOR_VIEW, vector editing methods will return ERROR_VECTOR_LOCKED and some editing related properties will be read only.
Please note that the MagGlass event and the UpdateMagGlass method are now obsolete. To achieve the same functionality, use the MagGlassExt event and the UpdateMagGlassExt method.
LEADTOOLS now supports an ImageList event for unselecting an item.
LEADTOOLS now supports loading and saving multi-page TIFF files using the ImageList control.
The Thumbnail Browser can now be used to create thumbnails for a single image file.
LEADTOOLS provides a new Deskew method that lets you specify the background color.
LEADTOOLS now supports Magnifying Glass features that let you update the bitmap from another source during the procedure.
LEADTOOLS also provides support for customizing the shape of the Magnifying Glass.
LEADTOOLS now supports File Transfer mode for acquiring images from TWAIN devices.
LEADTOOLS also now provides a method for determining whether a TWAIN device is available.
LEADTOOLS provides new support for changing the hue, saturation and value of images, allowing you to color replace a range of colors.
New functions let you create a region based on an RGB color range or an HSV color range.
LEADTOOLS can now convert between V4 and V5 DIBs.
DICOM now supports Structured IODs.
LEADTOOLS now supports the loading and saving of RAW uncompressed image data.
LEADTOOLS can now convert from JPEG compressed DIBs.
LEADTOOLS can now convert from RLE4 and RLE8 compressed DIBs.
LEADTOOLS provides more support for grouping and ungrouping annotation objects.
LEADTOOLS now provides support for changing the background color of Redact, Push pin, Note and Hilite objects created by an automation object.
LEADTOOLS provides more support for undoing automation operations in automated annotations.
LEADTOOLS now provides support for loading and saving PDF files.
LEADTOOLS now provides support for controlling the rasterizing of vector image files.
LEADTOOLS now provides view perspective when getting file information.
LEADTOOLS can now allocate memory in tiles for supporting very large images.
LEADTOOLS now supports 12 and 16-bit grayscale histograms.
The Vector toolkit now supports faster loading for DWF, DWG, DXF and HPGL files.
The Vector toolkit now supports more entities for DWG and DXF files.
Data binding in the Main OCX and the OLE DB OCX has been changed. The image data is stored first, followed by the annotation data. This allows other applications to read data from the database field.
LEADTOOLS now provides methods for converting between Bitmap coordinates and Client coordinates.

The LEADTOOLS Multimedia toolkits currently include many of the functions documented in the Ltnetocxn.hlp help file and this manual. This is the final version of the LEADTOOLS Multimedia toolkit that will contain those functions. In future releases, the functions documented in the Ltnetocxn.hlp help file will only be available in the LEADTOOLS Internet Imaging toolkits.
