Format introduction | A camera raw image file contains minimally processed data from the image sensor of either a digital camera, image scanner, or motion picture film scanner. Raw files are named so because they are not yet processed and therefore are not ready to be printed or edited with a bitmap graphics editor. | Truevision TGA, often referred to as TARGA, is a raster graphics file format created by Truevision Inc. It was the native format of TARGA and VISTA boards, which were the first graphic cards for IBM-compatible PCs to support Highcolor/truecolor display. |
Technical details | Raw files contain the information required to produce a viewable image from the camera's sensor data. The structure of raw files often follows a common pattern: a short file header, camera sensor metadata, an image thumbnail and the sensor image data etc, | The format can store image data with the maximum 24 bits of RGB and an extra 8-bit alpha channel. Color data can be color-mapped, or in direct color or truecolor format. Image data may be stored raw, or optionally, a lossless RLE compression similar to PackBits can be employed. |
