void Set_Edge_Weight | ( | double | weight | ) |
Makes the edges of polygons, circles, ellipses, shells, and meshes broader or narrower than normal.
weight | - Scale factor ( rounded to the nearest integer ) to be applied to the edge-line width. |
A line weight of "2.0" causes the lines to be rendered twice as thick.
The "1.0" edge weight always corresponds to an edge one pixel wide, which usually comes out to about 0.1 percent of the screen size. In the exceptional case where a device has very small pixels---but only in the exceptional case---the 1.0 weight is forced to correspond to 0.1 percent of the screen.
There is not yet an implemented method of inquiring precisely how wide a "normal" line actually is on a given display screen.
Thinning lines will probably not get you any visible change if your device doesn't have sufficient resolution. As a corollary, you should watch out for lines that might---someday, on a new device---be entirely too thin.
Depending on the implementation, the system might elect to thin very thick lines that have been scrunched down into a small Window.
void UnSet_Edge_Weight | ( | void | ) |
Removes all settings established by a previous call to Set_Edge_Weight().
