CIMG Class

CIMG Class

The IMG class performs read and write operations on grid file data. When efficient access along both rows and columns is desired the PG class is recommended (see PG and PGU); the IMG is first created, then the PG is obtained from the IMG using GetPG_IMG.

The CIMG type exposes the following members.

Methods

	Name	Description
	Average2	Reduce the dimensions in a 2D pager by a factor of 2
	Copy	Copy IMGs.
	Create	Creates an IMG not tied to a file at all
	CreateFile	Creates an Image object tied to a grid file.
	CreateMem	Creates an IMG object that is backed only by memory.
	CreateNewFile	Creates an output image file using User defined info.
	CreateOutFile	Creates an output image file using input image info.
	CreateProjected	Applies a projection to an image.
	CreateProjected2	Applies a projection to an image, specify cell size.
	CreateProjected3	Same as CreateProjected2_IMG, but set expansion of bounds.
	Dispose	Releases the unmanaged resources used by the CIMG and optionally releases the managed resources (Overrides CHANDLEDispose(Boolean).)
	GethPG	Get the actual pager of a grid.
	GetInfo	Retrieves location information about this image.

	GetPG	Get a copy of the pager of a grid.
	GetProjectedCellSize	Returns default cell size from projected image.
	GetTR	Get the trend information from a grid.
	iElementType	Returns the element type.
	iEType	Returns the element type.
	iGetDefITR	Get default transform, if it exists
	iIsColour	Is this a Geosoft colour grid?
	iIsValidIMGFile	Is this a valid IMG file?
	iIsValidIMGFileEx	Is this a valid IMG file? Returns error message if it cannot be opened for any reason.
	iNE	Gets the # of elements in the optimal KX direction.
	Inherit	Inherit a projection/new cell size on the IMG.
	InheritIMG	Make a grids match in size and coordinate system
	iNV	Gets the # of vectors in the optimal KX direction.
	iNX	Gets the # of X elements.
	iNY	Gets the # of Y elements.
	iQuery	Query information about the IMG
	iQueryKX	Asks the IMG for the most efficient way to access the data.
	iSetDefITR	Set default transform
	iUserPreferenceToPlotAsColourShadedGrid	Returns the global setting.
	LoadIMG	Loads an IMG into a master IMG.
	LoadIntoPager	Load IMG data from file into a pager to increase access time.
	OptKX	Force optimal KX as desired.
	ReadV	Read a vector in the optimal KX direction.
	ReadX	Read a column (constant X)
	ReadY	Read a row (constant Y)
	RefreshGI	Refresh the GI of a grid after it has moved or changed.
	Relocate	Re-locate a grid image.
	Report	Writes grid info report to a file
	ReportCSV	Writes grid info as a line to a CSV file
	rGetRealParameter	Store a real parameter in an IMG object
	rGetZ	Gets the grid value at a point
	rQuery	Query information about the IMG
	SetGridUnchanged	Mark the grid as unchanged so it will not output lineage
	SetInfo	Sets location information about this image.
	SetIPJ	Set the projection of a grid.
	SetMETA	Set the metadata of a grid.
	SetPG	Copy a pager into the pager of a grid.
	SetRealParameter	Store a real parameter in an IMG object
	SetTR	Set the trend information to a grid.
	Sync	Syncronize the Metadata for this Grid
	WriteV	Write a vector in the optimal KX direction.
	WriteX	Write a column (constant X)
	WriteY	Write a row (constant Y)
