Parameter descriptions

Input: Input vector segment(s)

Specifies the vector segment(s) containing the vectors from which the raster image will be constructed.

OutputRaster: Output raster channel(s)

If a raster output is required, this parameter specifies the output raster channel to receive the rasterized image.

OutputBitmap: Output bitmap segment(s)

If a bitmap output is required, this parameter specifies the output bitmap segment to receive the rasterized image.

Field Name

Specifies the field name that contains the values used to grid the polygons or edges.

If this parameter is specified as ZCOORD, the actual z-coordinates of the first vertex of each vector shape are used. Field names are not case-sensitive, and they do not need to be specified in complete form. If more than one match exists, the first name is used.

If the specified attribute does not exist and it is not ZCOORD, the ShapeIDs of the vector shapes are used for gridding.

Algorithm

Specifies the algorithm to use when converting polygons to rasters.

Report

Specifies where to direct the generated report.

Available options are:

• LOG: generates a report on the terminal (default)
• <modulename.RPT>: appends a report to the module's RPT file
• DISK: generates a report on file "IMPRPT.LST"

Details

GRDPOL takes an input polygon segment or arcs in vector segments and converts all inside areas to a raster image.
