    SYNOPSIS

           #include <image.h>
    
    
    

    DESCRIPTION

           The Magick Image File Format (MIFF) is a platform-independent format
           for storing bitmap images.  MIFF is a part of the ImageMagick toolkit
           of image manipulation utilities for the X Window System.  ImageMagick
           is capable of converting many different image file formats to and from
           MIFF (e.g. JPEG, XPM, TIFF, etc.).
    
           A MIFF image file consist of two sections.  The first section is a
           header composed of keys describing the image in text form.  The next
           section is the binary image data.  The header is separated from the
           image data by a : character immediately followed by a newline.
    
           The MIFF header is composed entirely of LATIN-1 characters.  The fields
           in the header are key and value combination in the key=value format,
           with each key and value separated by an equal sign (=).  Each key=value
           combination is delimited by at least one control or whitespace charac-
           ter.  Comments may appear in the header section and are always delim-
           ited by braces.  The MIFF header always ends with a colon (:) charac-
           ter, followed by a ctrl-Z character.  It is also common to proceed the
           colon with a formfeed and a newline character.  The formfeed prevents
           the listing of binary data when using more(1) under Unix where the
           ctrl-Z has the same effect with the type command on the Win32 command
           line.
    
           The following is a list of key=value combinations that may be found in
           a MIFF file:
    
           background-color=color
                  border-color=color matte-color=color these optional keys
                  reflects the image background, border, and matte colors respec-
                  tively. A color can be a name (e.g. white) or a hex value (e.g.
                  #ccc).
    
           class=DirectClass
                  class=PseudoClass the type of binary image data stored in the
                  MIFF file.  If this key is not present, DirectClass image data
                  is assumed.
    
           colors=value
                  the number of colors in a DirectClass image. For a PseudoClass
                  image, this key specifies the size of the colormap.  If this key
                  is not present in the header, and the image is PseudoClass, a
                  linear 256 color grayscale colormap is used with the image data.
                  The maximum number of colormap entries is 65535.  col-
                  orspace=CMYK the colorspace of the pixel data.  The default is
                  RGB.
    
           columns=value
                  the width of the image in pixels.  This is a required key and
                  from 0 to 255 (depth 8) or 65535 (depth 16).  If this key is
                  absent, a depth of 8 is assumed.
    
           dispose value
                  GIF disposal method.
    
                  Here are the valid methods:
    
                       0  No disposal specified.
                       1  Do not dispose between frames.
                       2  Overwrite frame with background color from header.
                       3  Overwrite with previous frame.
    
           gamma=value
                  the gamma of the image.  If it is not specified, a gamma of 1.0
                  (linear brightness response) is assumed,
    
           id=ImageMagick
                  identifies the file as a MIFF-format image file.  This key is
                  required and has no default.  Although this key can appear any-
                  where in the header, it should start as the first key of the
                  header in column 1.  This will allow programs like file(1) to
                  easily identify the file as MIFF.
    
           iterations value
                  the number of times an image sequence loops before stopping.
    
           label={value}
                  defines a short title or caption for the image.  If any whites-
                  pace appears in the label, it must be enclosed within braces.
    
           matte=True
                  matte=False specifies whether a DirectClass image has matte
                  data.  Matte data is generally useful for image compositing.
                  This key has no meaning for pseudo-color images.
    
           montage=<width>x<height>{+-}<x offset>{+-}<y offset>
                  size and location of the individual tiles of a composite image.
                  See X(1) for details about the geometry specification.
    
                  Use this key when the image is a composite of a number of dif-
                  ferent tiles.  A tile consists of an image and optionally a bor-
                  der and a label.  <width> is the size in pixels of each individ-
                  ual tile in the horizontal direction and <height> is the size in
                  the vertical direction.  Each tile must have an equal number of
                  pixels in width and equal in height.  However, the width can
                  differ from the height.  <x offset> is the offset in number of
                  pixels from the vertical edge of the composite image where the
                  first tile of a row begins and <y offset> is the offset from the
                  horizontal edge where the first tile of a column begins.
    
                  If this key is specified, a directory of tile names must follow
                  green-primary=x,y blue-primary=x,y white-point=x,y this optional
                  key reflects the chromaticity primaries and white point.
    
           rendering-intent=saturation
                  rendering-intent=perceptual rendering-intent=absolute rendering-
                  intent=relative Rendering intent is the CSS-1 property that has
                  been defined by the International Color Consortium
                  (http://www.color.org).
    
           resolution=<x-resolution>x<y-resolution>
                  vertical and horizontal resolution of the image.  See units for
                  the specific resolution units (e.g. pixels per inch).
    
           rows=value
                  the height of the image in pixels.  This is a required key and
                  has no default.
    
           scene=value
                  the sequence number for this MIFF image file.  This optional key
                  is used when a MIFF image file is one in a sequence of files
                  used in an animation.
    
           signature=value
                  this optional key contains a string that uniquely identifies the
                  image pixel contents.  NIST's SHA-256 message digest algorithm
                  is recommended.
    
           units=pixels-per-inch
                  units=pixels-per-centimeter image resolution units.
    
                  Other key value pairs are permitted.  If a value contains
                  whitespace it must be enclosed with braces as illustrated here:
    
                      id=ImageMagick
                      class=PseudoClass  colors=256
                      compression=RunlengthEncoded  packets=27601
                      columns=1280  rows=1024
                      signature=d79e1c308aa5bbcdeea8ed63df412da9

                      <FF>
                      :
    
           Note that key=value combinations may be separated by newlines or spaces
           and may occur in any order within the header.  Comments (within braces)
           may appear anywhere before the colon.
    
           If you specify the montage key in the header, follow the header with a
           directory of image tiles.  This directory consists of a name for each
           tile of the composite image separated by a newline character.  The list
           is terminated with a NULL character.
    
    
           PseudoClass images (class=PseudoClass) are colormapped RGB images. The
           colormap is stored as a series of red, green, and blue pixel values,
           each value being a byte in size. If the image depth is 16, each col-
           ormap entry consumes two bytes with the most significant byte being
           first. The number of colormap entries is defined by the colors key.
           The colormap data occurs immediately following the header (or image
           directory if the montage key is in the header). PseudoClass image data
           is an array of index values into the color map. If there are 256 or
           fewer colors in the image, each byte of image data contains an index
           value. If the image contains more than 256 colors or the image depth is
           16, the index value is stored as two contiguous bytes with the most
           significant byte being first. If matte is true, each colormap index is
           followed by a 1 or 2-byte alpha value.
    
           The image data in a MIFF file may be uncompressed, runlength encoded,
           Zip compressed, or BZip compressed. The compression key in the header
           defines how the image data is compressed. Uncompressed pixels are just
           stored one scanline at a time in row order. Runlength encoded compres-
           sion counts runs of identical adjacent pixels and stores the pixels
           followed by a length byte (the number of identical pixels minus 1). Zip
           and BZip compression compresses each row of an image and preceeds the
           compressed row with the length of compressed pixel bytes as a word in
           most significant byte first order.
    
           MIFF files may contain more than one image.  Simply concatenate each
           individual image (composed of a header and image data) into one file.
