For digital file formats in general, see File format. Image file formats are standardized means of organizing and storing digital images. Image files are composed of digital data in one of these formats that can be rasterized for use on a computer display or printer. An image file format may store data in uncompressed, compressed, or vector formats. Once rasterized, an image becomes a grid of pixels, each of which has a number of bits to designate its color equal to the color depth of the device displaying it. Image file sizes. Images can be compressed in various ways, however. A compression algorithm stores either an exact representation or an approximation of the original image in a smaller number of bytes that can be expanded back to its uncompressed form with a corresponding decompression algorithm. Images with the same number of pixels and color depth can have very different compressed file size. Considering exactly the same compression, number of pixels, and color depth for two images, different graphical complexity of the original images may also result in very different file sizes after compression due to the nature of compression algorithms.

Non-attacking chess pieces (sixth edition) by Vaclav Kotesovec The book is devoted to the question of the number of arrangements of non-attacking chess pieces of the. With some compression formats, images that are less complex may result in smaller compressed file sizes. This characteristic sometimes results in a smaller file size for some lossless formats than lossy formats. For example, graphically simple images (i. File size increases only with the addition of more vectors. For example, a 6. BImage file compression. Lossless compression generally, but not always, results in larger files than lossy compression. Lossless compression should be used to avoid accumulating stages of re- compression when editing images. Lossy compression algorithms preserve a representation of the original uncompressed image that may appear to be a perfect copy, but it is not a perfect copy. Often lossy compression is able to achieve smaller file sizes than lossless compression. Most lossy compression algorithms allow for variable compression that trades image quality for file size. Major graphic file formats. The PNG, JPEG, and GIF formats are most often used to display images on the Internet. These graphic formats are listed and briefly described below, separated into the two main families of graphics: raster and vector. In addition to straight image formats, Metafile formats are portable formats which can include both raster and vector information. Examples are application- independent formats such as WMF and EMF. The metafile format is an intermediate format. Most applications open metafiles and then save them in their own native format. Page description language refers to formats used to describe the layout of a printed page containing text, objects and images. Examples are Post. Script, PDF and PCL. JPEG/JFIF. The JPEG/JFIF filename extension is JPG or JPEG. Nearly every digital camera can save images in the JPEG/JFIF format, which supports eight- bit grayscale images and 2. JPEG applies lossy compression to images, which can result in a significant reduction of the file size. Applications can determine the degree of compression to apply, and the amount of compression affects the visual quality of the result. When not too great, the compression does not noticeably affect or detract from the image's quality, but JPEG files suffer generational degradation when repeatedly edited and saved. The compression methods used are different from the ones in standard JFIF/JPEG; they improve quality and compression ratios, but also require more computational power to process. JPEG 2. 00. 0 also adds features that are missing in JPEG. It is not nearly as common as JPEG, but it is used currently in professional movie editing and distribution (some digital cinemas, for example, use JPEG 2. The Exif (Exchangeable image file format) format is a file standard similar to the JFIF format with TIFF extensions; it is incorporated in the JPEG- writing software used in most cameras. Its purpose is to record and to standardize the exchange of images with image metadata between digital cameras and editing and viewing software. The metadata are recorded for individual images and include such things as camera settings, time and date, shutter speed, exposure, image size, compression, name of camera, color information. When images are viewed or edited by image editing software, all of this image information can be displayed. The actual Exif metadata as such may be carried within different host formats, e. TIFF, JFIF (JPEG) or PNG. IFF- META is another example. The TIFF (Tagged Image File Format) format is a flexible format that normally saves eight bits or sixteen bits per color (red, green, blue) for 2. TIFF or TIF filename extension. The tagged structure was designed to be easily extendible, and many vendors have introduced proprietary special- purpose tags – with the result that no one reader handles every flavor of TIFF file. Some offer relatively good lossless compression for bi- level (black& white) images. Some digital cameras can save images in TIFF format, using the LZW compression algorithm for lossless storage. TIFF image format is not widely supported by web browsers. TIFF remains widely accepted as a photograph file standard in the printing business. TIFF can handle device- specific color spaces, such as the CMYK defined by a particular set of printing press inks. OCR (Optical Character Recognition) software packages commonly generate some form of TIFF image (often monochromatic) for scanned text pages. GIF (Graphics Interchange Format) is in normal use limited to an 8- bit palette, or 2. Due to GIF's simplicity and age, it achieved almost universal software support. Due to its animation capabilities, it is still widely used to provide image animation effects, despite its low compression ratio compared to modern video formats. The BMP file format (Windows bitmap) handles graphic files within the Microsoft Windows OS. Typically, BMP files are uncompressed, and therefore large and lossless; their advantage is their simple structure and wide acceptance in Windows programs. The PNG (Portable Network Graphics) file format was created as a free, open- source alternative to GIF. The PNG file format supports eight- bit paletted images (with optional transparency for all palette colors) and 2. GIF supports only 2. Compared to JPEG, PNG excels when the image has large, uniformly colored areas. Even for photographs – where JPEG is often the choice for final distribution since its compression technique typically yields smaller file sizes – PNG is still well- suited to storing images during the editing process because of its lossless compression. PNG provides a patent- free replacement for GIF (though GIF is itself now patent- free), and can also replace many common uses of TIFF. Indexed- color, grayscale, and truecolor images are supported, plus an optional alpha channel. The Adam. 7 interlacing allows an early preview, even when only a small percentage of the image data has been transmitted. PNG can store gamma and chromaticity data for improved color matching on heterogeneous platforms. PNG is designed to work well in online viewing applications like web browsers and can be fully streamed with a progressive display option. PNG is robust, providing both full file integrity checking and simple detection of common transmission errors. Animated formats derived from PNG are MNG and APNG. The latter is supported by Mozilla Firefox and Opera and is backwards compatible with PNG. PPM, PGM, PBM, and PNM. These are either pure ASCII files or raw binary files with an ASCII header that provide very basic functionality and serve as a lowest common denominator for converting pixmap, graymap, or bitmap files between different platforms. Several applications refer to them collectively as PNM (Portable a. Ny Map). Web. P is a new open image format that uses both lossless and lossy compression. It was designed by Google to reduce image file size to speed up web page loading: its principal purpose is to supersede JPEG as the primary format for photographs on the web. Web. P is based on VP8's intra- frame coding and uses a container based on RIFF. HDR raster formats. Newer alternatives are showing up, though. RGBE is the format for HDR images originating from Radiance and also supported by Adobe Photoshop. The High Efficiency Image File Format (HEIF) is an image container format that was standardized by MPEG on the basis of the ISO base media file format. While HEIF can be used with any image compression format, the HEIF standard specifies the storage of HEVC intra- coded images and HEVC- coded image sequences taking advantage of inter- picture prediction. BAT. SPIFF, which has the ISO designation 1. JPEG/BAT, but it has little support. It may be superseded by JPEG 2. DIG 2. 00. 0: ISO SC2. WG1, JPEG - Information Links. Digital Imaging Group, . Its purpose is to replace the JPEG image format when quality or file size is an issue. Its main advantages are: High compression ratio. Files are much smaller than JPEG for similar quality. Supported by most Web browsers with a small Javascript decoder (gzipped size: 7. KB). Based on a subset of the HEVC open video compression standard. Supports the same chroma formats as JPEG (grayscale, YCb. Cr 4: 2: 0, 4: 2: 2, 4: 4: 4) to reduce the losses during the conversion. An alpha channel is supported. The RGB, YCg. Co and CMYK color spaces are also supported. Native support of 8 to 1. Lossless compression is supported. Various meta data (such as EXIF) can be included. Other raster formats. It uses the MANIAC (Meta- Adaptive Near- zero Integer Arithmetic Coding) entropy encoding algorithm, a variant of the CABAC (context- adaptive binary arithmetic coding) entropy encoding algogithm.
