DrawLabel immediately returning points delimiting label area.

Available also on: Delphi | .NET | ActiveX.


// Java

// Oxygene
  procedure DrawLabel(
    var _points : TGIS_DrawBuf
  ); virtual;


Name Type Description
_points TPoint[]
list of points delimiting label area;


Each drawn label is described as a sequence of delimiting points starting from left top corner of the label and ending with the same point. For arc shapes labels can be drawn for each part, so the buffer can be then a set of such sequences.

When using this operation, never call any function which uses FindFirst..FindNext (any function which iterates through the shapes using it - so never use inside an operation like Locate etc.).

See TGIS_LayerVector.DrawChart for example.
