Purpose |
Draw a series of connected line segments. |
|
Syntax |
GRAPHIC POLYLINE points [, rgbColor&] |
|
Remarks |
The Coordinates are specified in Page Units. Line width can be set using GRAPHIC WIDTH. If line width is set to 1 (the default), the line style can be set with GRAPHIC STYLE. GRAPHIC POLYLINE neither uses, nor updates, the last point referenced (POS). Windows graphic conventions consider the final x and y coordinates to be exclusive. Therefore, by default, the final pixel is not drawn unless Overlap Mode is enabled. See GRAPHIC SET OVERLAP for details. |
|
points |
User-defined type that defines the number of vertices and the location of each. There must be at least two, and no more than 1024 vertices. The first member is a long integer point count, followed directly by the appropriate number of single precision floats to specify the actual coordinates. Floating point coordinates are required, because of the possibility of their use as world coordinates with SCALE. You can use a type with a scalar list, like this: TYPE PolyPoints count as long x1 as single y1 as single x2 as single y2 as single x3 as single y3 as single END TYPE Or, you can create an array using point types, like this: TYPE PolyPoint x as single y as single END TYPE
TYPE PolyArray count as long xy(1 TO 3) as PolyPoint END TYPE |
|
rgbColor& |
Optional RGB color of the polyline. If omitted (or -1), the color defaults to the current foreground color. |
