GR - Multifile General Raster Image Interface
GRattrinfo/mgatinf -- Retrieves information about an attribute.
GRcreate/mgcreat -- Creates a new raster image.
GRend/mgend -- Terminates the GR interface session.
GRendaccess/mgendac -- Terminates access to a raster image.
GRfileinfo/mgfinfo -- Retrieves the number of raster images and the number of global attributes in the file.
GRfindattr/mgfndat -- Finds the index of a data object's attribute given an attribute name.
GRgetattdatainfo -- Retrieves location and size of attribute's data. (H4 Mapping project specific)
GRgetattr/mggnatt/mggcatt -- Reads the values of an attribute for a data object.
GRgetchunkinfo/mggichnk -- Raster image identifier returned by GRcreate or GRselect
GRgetcompinfo/mggcompress -- Retrieves raster image data compression type and compression information.
GRgetdatainfo -- Retrieves location and size of data blocks in a specified raster image, starting at a specified block. (H4 Mapping project specific)
GRgetiminfo/mggiinf -- Retrieves general information about a raster image.
GRgetlutid/mggltid -- Gets the identifier of a palette given its index.
GRgetlutinfo/mgglinf -- Retrieves information about a palette.
GRgetnluts/mggnluts -- Retrieves the number of palettes for an image.
GRidtoref/mgid2rf -- Maps a raster image identifier to a reference number.
GRluttoref/mglt2rf -- Maps a palette identifier to a reference number.
GRnametoindex/mgn2ndx -- Maps the name of a raster image to an index.
GRreadchunk/mgrchnk/mgrcchnk -- Reads a data chunk from a chunked raster image (pixel-interlace only)
GRreadimage/mgrdimg/mgrcimg -- Raster image identifier returned by GRcreate or GRselect
GRreadlut/mgrdlut/mgrclut -- Reads a palette.
GRreftoindex/mgr2idx -- Maps the reference number of a raster image to an index.
GRreqimageil/mgrimil -- Specifies the interlace mode to be used in the subsequent raster image read operation(s).
GRreqlutil/mgrltil -- Specifies the interlace mode to be used in the next palette read operation(s).
GRselect/mgselct -- Selects the existing raster image.
GRsetaccesstype/mgsactp -- Sets the access for an RI to be either serial or parallel I/O.
GRsetattr/mgsnatt/mgscatt -- Assigns an attribute to a raster image or a file.
GRsetcompress/mgscompress -- Specifies if the raster image will be stored in a file as a compressed raster image.
GRsetchunk/mgschnk -- Makes a raster image a chunked raster image.
GRsetchunkcache/mgscchnk -- Specifies the maximum number of chunks to cache.
GRsetexternalfile/mgsxfil -- Specifies that the raster image will be written to an external file.
GRstart/mgstart -- Initializes the GR interface.
GRwritechunk/mgwchnk/mgwcchnk -- Writes a data chunk to a chunked raster image (pixel-interlace only)
GRwriteimage/mgwrimg/mgwcimg -- Writes a raster image.
GRwritelut/mgwrlut/mgwclut -- Writes a palette.
GR2bmapped -- Checks whether a raster image is to be mapped
