Changes from Version 14 to Version 14.5
Version 14.5 of the LEADTOOLS API has changed from Version 14 as follows:
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 L_AnnSetOptions
function. 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 XML Format
New Text Annotation Options
For detailed information regarding the new features, refer to New Annotation Features of Version 14.5.
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 has added new image processing
functions to create a Perlin noise, and to apply an effect to the bitmap
that makes it look like it has been drawn with colored pencils.
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 to load 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 a new functionality,
which handles the TIFF and Exif files, such as compact TIFF files, enumerates
all the tags in a TIFF and Exif files, and deletes a tag 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 JBIG2 file, you can get or change
the current values for the control options used by LEADTOOLS.
When obtaining image file information, you
can get or change the current information for a filter(s) used by LEADTOOLS.
LEADTOOLS provides functionality for compressing
and decompressing ABIC images in buffers.
Please note

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)
