Purpose |
Draw a series of connected lines on a host printer page. |
|
Syntax |
XPRINT POLYLINE points [, rgbColor&] |
|
Remarks |
The coordinate points are specified in pixels, unless
optional world coordinates have been defined with an XPRINT
SCALE statement. Line width can be set using XPRINT
WIDTH. If line width is set to 1 (the default), the line style
can be set with XPRINT STYLE.
XPRINT POLYLINE neither uses, nor updates, the last point referenced (
Windows graphic conventions consider the final x2 and y2 coordinates to be exclusive. Therefore, by default, the final pixel is not drawn unless Overlap Mode is enabled. See XPRINT 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 polygon edge. If omitted (or -1), the edge color defaults to the current foreground color for the host printer page. |
