#Raster image file formats zip#

The vector format for image files is more 'logical' than 'physical'. These are many other proprietary and open raster format types for different tasks, but those listed above are the basics for most graphic operations and software. RAW Files from different static image cameras (e.g., Canon RW2, Nikon NEF etc.), providing an unprocessed camera image, for converting a specific raster format to JPEG or TIFF files.TIFF File (Tagged Image File Format) is another lossless format for graphics, allowing big color depth but often requiring biggest space due to many tags and attributes of this raster format.GIF File (Graphic Image File) is the one of earliest raster format types, providing a bitmap picture with a possibility of animation and good compression rate but only a 256-color depth.PNG File (Portable Network Graphics) is the “lossless” raster format that allows keeping all details and fine lines of an image intact.JPEG File (JPG) is the most popular raster format extension for photos, allowing compressing neighbor pixels into interpolated squares.This reduction is a great necessity (for example, bitmap raster format data for modest 6000x4000 pixels with 8-bit color depth will take about 72 megabytes of raw space). Each raster type except BMP allows some compression for reducing a raster size. This is no way to create a best raster format.

For convenience, almost each other format of raster data packs these bitmaps by some way, from direct ZIP or LZH archiving to more complex schemes. The base of a raster image is a simple array of dots called a 'bitmap' (this type of image contains in a popular BMP raster file format extension).

This representation is a 'physical' map of dots merged in an image. Raster format is a simple type of graphics representation, where an image consists of a raster (an array of two or, perhaps, more dimensions), and each item of this array is a graphical dot with its own color and, perhaps, other characteristics.
