Annotation SDK:
Annotation (Image Mark-up) Programming SDK - C++ Class Library, C DLL, .NET Classes and WPF Controls.
LEADTOOLS offers a variety of annotation (document mark-up) options that can be added to document, grayscale and color images in a presentation layer. With LEADTOOLS the end-user can draw, reposition and change the attributes (color, size, etc.) of any of the 30+ built-in objects types. From simple objects such as lines and rectangles to an enhanced redaction object that can restore parts of an image that were blacked out. When combined with annotation security, the redaction objects provide a means of granting user-level access to parts of an image. To provide a superior means of security and privacy, LEADTOOLS has an Encrypt/Decrypt object to encode an area of the image without introducing any new colors, thereby maintaining higher quality with lossy compressions.
Annotation objects can be stored as a separate object presentation 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 LEAD, DICOM or Wang annotation tags within a TIFF file. Also, you can export the annotations objects to a standard Windows metafile. With the LEADTOOLS SDK, you can choose between low level access to the annotations, or you can implement annotation support through a fully automated user interface presentation mode with a ready to use customizable toolbar, pop-up menus and property dialogs. The annotation features provided in LEADTOOLS can be used in any application where image markup is required.
