\defgroup raw RAW - RAW File * * \par * The file must be open/created with the functions \ref imFileOpenRaw and \ref imFileNewRaw. * * \section Description * * \par * Internal Implementation. * \par * Supports RAW binary images. This is an unstructured and uncompressed binary data. * It is NOT a Camera RAW file generated in many professional digital cameras. \n * You must know image parameters a priori and must set the IM_INT attributes "Width", "Height", "ColorMode", "DataType" * before the imFileReadImageInfo/imFileWriteImageInfo functions. * \par * The data must be in binary form, but can start in an arbitrary offset from the begining of the file, use attribute "StartOffset". * The default is at 0 offset. * \par * Integer sign and double precision can be converted using attribute "SwitchType". \n * The conversions will be BYTE<->CHAR, USHORT<->SHORT, INT<->UINT, FLOAT<->DOUBLE. * \par * Byte Order can be Little Endian (Intel=1) or Big Endian (Motorola=0), use the attribute "ByteOrder", the default is the current CPU. * \par * The lines can be aligned to a BYTE (1), WORD (2) or DWORD (4) boundaries, ue attribute "Padding" with the respective value. * \par * If the compression is ASCII the data is stored in textual format, instead of binary. * In this case SwitchType and ByteOrder are ignored, and Padding should be 0. * \par * When reading, if data type is BYTE, color space is RGB and data is packed, then the attribute "RGB16" is consulted. * It can has values "555" or "565" indicating a packed 16 bits RGB pixel is stored with the given bit distribution for R, G and B. * \par * See \ref im_raw.h * * \section Features * \verbatim Data Types: <all> Color Spaces: all, except MAP. Compressions: NONE - no compression default ASCII (textual data) Can have more than one image, depends on "StartOffset" attribute. Can have an alpha channel. Components can be packed or not. Lines arranged from top down to bottom or bottom up to top.
