MtkGenericMapInfo()

MTKt_status MtkGenericMapInfo	(	double	Min_x,
		double	Min_y,
		double	Resolution_x,
		double	Resolution_y,
		int	Number_pixel_x,
		int	Number_pixel_y,
		MTKt_OriginCode	Origin_code,
		MTKt_PixRegCode	Pix_reg_code,
		MTKt_GenericMapInfo *	Map_info
	)

Initialize a MTKt_GenericMapInfo structure.

Min_x and Min_y contains the minimum x,y coordinates at the edge of the map.

Resolution_x is the size of a pixel along the X-axis. Resolution_y is the size of a pixel along the Y-axis.

Number_pixel_x and number_pixel_y specifies the size of the map in pixels along the respective axes.

Origin_code defines the corner of the map at which pixel 0,0 is located. Possible values are: MTKe_ORIGIN_UL - Upper Left (min X, max Y) MTKe_ORIGIN_UR - Upper Right (max X, max Y) MTKe_ORIGIN_LL - Lower Left (min X, min Y) MTKe_ORIGIN_LR - Lower Right (max X, min Y)

Pix_reg_code defines whether a pixel value is related to the corner or center of the corresponding area of that pixel on the map. If the corner is used, then it is always the corner corresponding to the corner of the origin. Possible values are: MTKe_PIX_REG_CENTER - Center MTKe_PIX_REG_CORNER - Corner

Returns

MTK_SUCCESS if successful.

Example:

status = MtkGenericMapInfo()
