Remarks

The MedicalViewer is used to display graphics from a bitmap, metafile, icon, JPEG, GIF or PNG (or any other image file format supported by Leadtools) file. It provides support for displaying one or more images and for the real-time manipulation of one or more images. This control is available only in the Medical toolkits. For more information, refer to Document/Medical Edition Support and Licensing Requirements

This control is a high-level component for building medical display applications such as DICOM viewers, view stations, Teleradiology solutions, and high-end diagnostic workstations found in radiology and other medical specialty departments. When building a PACS for radiology, cardiology, mammography, ophthalmology, pathology, dermatology, dentistry or any other specialty, this control will eliminate project complexity and provide a solid, reliable foundation.

Typical applications that can be built using this control include: Key Features: For more information, refer to Applying Actions and Using the Image Viewer.
