ImagerSDK Annotation Fax Viewer - Version 4.5 With the Image Viewer, you can view, rotate, page, and scale images pre-emptively without even waiting for the previous request to complete. Background processing of the current image ensures that the fax image pans and region updates are carried out at bitmap speed. Image enhancement features are built in to darken compressed fax images, or convert compressed images to 16 shades of grey. Support for color conversion features ensures that color images look their best when converted to black and white for fax transmission. Imager SDK also provides specialized support for file folders, custom file formats and secure fax encryption. An optional upgrade path provides powerful annotation, MAPI, and VIM support features.
