Changes from Version 14 to Version 14.5

Version 14.5 of the LEADTOOLS C++ Class Library has changed from Version 14 as follows:

With this mid-release of LEADTOOLS version 14, many new features are being introduced to the annotations. Some of these features alter the way annotations are displayed. Other features change or enhance the user interface. To maintain backward compatibility within version 14, most of these features must be enabled by calling the LAnnotation::SetOptions functions. In LEADTOOLS version 15, these options will be enabled by default.

• The following features are being introduced:

• New Rubber Stamp Display Style

• New XP Style Annotation Toolbar

• New Alpha Background Fill Option

• New Annotation Rotate Option

• New Annotation Side Handles

• New Annotation Multi-select

• New Annotation Cursors

• New ESC to Cancel

• New Calibrate Ruler Feature

• New Dot Dash Lines

• New Text Annotation Options

• New XML Format

• For detailed information regarding the new features, refer to New Annotation Features of Version 14.5.

• LEADTOOLS now supports the Zoom View, which provides a means of "zooming in" on the image loaded into the window to which it is attached. This is similar to having multiple magnifying glasses on the same source image.

• LEADTOOLS supports the GeoKeys, which are TIFF files containing a few extra TIFF tags describing the image location, scale at which the picture was taken, and other information useful for topographic applications.

• LEADTOOLS supports creating a Kaufmann region.

• LEADTOOLS has added new functionality to the ImageList Control, for sorting the items in the image list based on their text or Extended Text attributes, inserting a list of bitmaps into the ImageList Control, and exporting a number of bitmaps from the ImageList Control to a bitmap list

• LEADTOOLS has added new functionality to change the image data type from signed to unsigned and vice versa.

• LEADTOOLS supports functions for loading embedded ICC profiles from JPEG, TIFF or EPS files.

• LEADTOOLS provides Image Optimization functionality to optimize certain image file formats, by saving images using the optimal bits per pixel, based on specific optimization options.

• LEADTOOLS supports CMYK functions, which handle CMYK TIFF Files as separate bitmaps.

• LEADTOOLS has added new functionality, which handles the TIFF and Exif files, such as compact TIFF files, enumerates all the tags in TIFF and Exif files, and deletes tags from TIFF and Exif files.

• LEADTOOLS supports reading a comment from a file at a specific location.

• LEADTOOLS has added new functionality to create a new region, or update an existing region, based on either an HSV range or an RGB range.

• When loading a TXT file, you can get or change the current values for the control options used by LEADTOOLS.

• When saving a JBIG2 file, you can get or change the current values for the control options used by LEADTOOLS.

• LEADTOOLS has added many new image processing functions.

• LEADTOOLS provides functionality for compressing and decompressing ABIC images in buffers.

• Please note that version 14.5 is the last version that will support the following file formats:

File Formats: MrSid Format (SID)

File Formats: DjVu Format (DJVU)

• LEADTOOLS now supports the following new file formats:

File Formats: ABC Format (ABC)

File Formats: ABIC Format (ABIC, ICA)

File Formats: JBIG2 Format (JB2)

File Formats: TXT Format (TXT)

Changed structures

• The LAYERINFO structure has 1 new member.
