CEMAP.iDigitizePolygon Method

CEMAPiDigitizePolygon Method

Same as iDigitze2_EMAP, but automatically close polygons.

Available since Oasis montaj version: 5.0
Limitations: May not be available if running outside of a Oasis Montaj or from a command line program.
License: Available to anyone.

Namespace: Geosoft.Desktop.GXNetX
Assembly: geosoft.desktop.gxnetx (in geosoft.desktop.gxnetx.dll)

Notes

This is the same as iDigitize2_EMAP, except that it automatically detects, (except for the 2nd and 3rd points) when a selected location is within the entered number of pixels from the starting point. If yes, the polygon is assumed to be closed, and the operation is the same as the RMB "done" command, and the process returns 0.

Syntax

C++

Parameters

vvx: Type: GeoEngine.Core.GXNetXCVV
Real X VV
vvy: Type: GeoEngine.Core.GXNetXCVV
Real Y VV
vvz: Type: GeoEngine.Core.GXNetXCVV
Real Z VV
img: Type: GeoEngine.Core.GXNetXCIMG
IMG for Z value, or <define>IMG_NULL</define> for no Z.
prompt: Type: SystemString
Command line prompt string
newline: Type: SystemInt32
0 for no newline 1 for automatic newline at each point
pixel_radius: Type: SystemInt32
Close the polygon if the selected location is within this radius in screen pixels.

Return Value

Type: Int32
0 if user digitized some points. 1 if user cancelled.
