PolyView is a 32-bit image viewer and format conversion tool. Packed with features, it's one of the best bargains in shareware. It supports most popular graphics image formats, including .bmp, .gif, .jpg, .pcx, .png, .tga, .pcd, and .tif, and can acquire blocks of images from scanners and digital cameras using built-in TWAIN support. It's multithreaded, so time-consuming operations (such as image file reading and writing) can be performed in parallel with user-interface operations. Need slide shows? You can create both full-screen and windowed varieties, using specified or random ordering, sound files, and transition effects. Other features include a image appearance-manipulation, filtering operations, interpolated zooming, sophisticated color-resolution, image-size-manipulation algorithms, thumbnails, directory browsers, OLE drag-and-drop methods, creation and playback of animated .gif files.
