Annotations
LEADTOOLS offers a variety of annotation (document markup) options that can be added to document, grayscale and color images. LEADTOOLS allows the end-user to reposition nodes of an existing free-hand object, which prevents the user from redrawing the object. Enhanced redact objects allow you to restore parts of an image that were blacked out. When combined with annotation security, these redact objects provide a means of granting user-level access to parts of an image. Annotation objects can be stored as a separate object layer, or can be burned or embedded into the actual image. LEADTOOLS allows you to read or write annotations as an external file or as a Wang annotation tag within a TIFF file. With LEADTOOLS, you can choose between low level access to the annotations, or you can implement annotation support through a fully automated mode with a ready to use floating, customizable toolbar and pop-up menus. The superior annotation features provided in LEADTOOLS can be used in any application where image markup is required.
With LEADTOOLS Document/Medical Annotation support you can:
Create any of the following objects: line, arrow, rectangle, ellipse, polygon, freehand line, text, highlighter, hot spot, note, stamp, redaction, button, audio clip, video, freehand hot spots, points, protractors, cross-products, push pins, rubber stamps, curve, closed curve, encryption, text pointer, polyruler, and RTF edit objects.
Create your own custom annotation objects with custom handles and user-defined behaviour.
Implement automated annotation support.
Customize the cursors for automation activities.
Implement annotation passwords (case-sensitive) providing security for every object.
Implement hyperlinks for every object. Hyperlinks can be user-defined messages, programs to run, or jumps to Web pages.
Modify text strings used in automated annotation support.
Scale and position a group to fit the displayed bitmap.
Fix annotation objects, so that they do not move when zooming/scrolling.
