Version 14.5 of the LEADTOOLS C API has changed from Version 14 as follows:
Annotations Updates. Many new features are being introduced to the annotations. Some alter the way annotations are displayed; others change or enhance the user interface.

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 XML Format
New Text Annotation Options
LEADTOOLS 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.
