The TIFF (Tagged Image File Format) is mainly for storing raster images, including photographs and line art. #Duplicate photo cleaner limitations windowsPCX was quite popular on early DOS and Windows systems, but is nowadays rare, having been largely replaced by formats which support better compression, such as GIF, JPEG and PNG. Most PCX files use a color palette, but the format has also been extended to allow 24-bit images. It was the native file format for one of the first popular DOS graphics programs for early PCs. The PCX format uses a simple form of run-length encoding (a type of lossless compression algorithm). Desktop backgrounds and images from scanners are usually stored in BMP files. Their large size makes them unsuitable for file transfer. The main advantage of BMP files is their wide acceptance and use in Windows programs. These files are typically not compressed resulting in large files. The BMP (bit mapped) format is used internally in the Microsoft Windows operating system to handle graphics images. The Adam7 -interlacing allows an early preview even when only a small percentage of the data of the image has been transmitted. Many older browsers do not yet support the PNG file format. The lossless PNG format is best suited for editing pictures, and the lossy formats like JPG are best for storage because of smaller file size. PNG excels when the image has large areas of uniform color. The PNG file format supports true color (16 million colors) whereas the GIF file format only 256 colors. The PNG (Portable Network Graphics) file format does almost everything that the GIF format does and does it better. It is not at all suitable for photographs. The GIF format does well with images having 256 colors or fewer. But, is being superseded by the PNG format. It is still used extensively on the Internet because of the great reservoir of GIF images available, and because it supports animation. As a result, it is not used for photographic work. The GIF file format is limited to an 8-bit pallete (256 colors). Because of the compression algorithm “artifacts” (blemishes) sometimes appear. These files are best kept in original form. But, JPEG files do suffer generational degradation when repeatedly edited and saved. Fortunately, the compression in most cases does not distract noticeably from the image. #Duplicate photo cleaner limitations fullNearly all digital cameras have the option to save images in JPEG format, some at different compression levels, such as “fine” and “standard.” The JPEG format supports full color and produces relatively small file sizes. The DOS filename extension is JPG, although other operating systems may use JPEG. VisiPics uses the ImageMagick libraries to load pictures, for more informations: The JPEG (Joint Photographic Experts Group) image files are a lossy format. ![]() Tested on a 100.000 pictures 15Gb archive, full results in 3 hours only.Smart Auto-Select mode, to save time while deleting pictures.Starts to display the results while scanning, you don't have to wait to delete your duplicates. ![]()
