GdViewer Image Viewer ActiveX (Site License) is a free image & PDF Viewer ActiveX control for your application. If you are a developer trying to have some pretty good image viewer ActiveX (and not bothering creating your own OCX), you can try this one out. The ActiveX control supports vb, vfp, .net, realbasic, delphi, c++. GdViewer OCX offers support of many popular image formats including bmp, rle, tif, multipage tif, jpg, j2k, jpe, wmf, emf, gif, ico, png, pcx, pnm and pdf. In addition, GdViewer is not just a viewer, but capable of manipulating the view panel, such as view, zoom, print, rotate, define display area, zoom on area, play animated gif, read exif gps and thumbnail tags. The best thing I note using GdViewer OCX is it can read PDF files. Download GdViewer Image Viewer is free.
