Line antialiasing is initially -disabled. -.P -If line antialiasing is disabled, -the actual width is determined by rounding the supplied width -to the nearest integer. -(If the rounding results in the value 0, -it is as if the line width were 1.) -If -$| DELTA x | ~>=~ | DELTA y |$, -\f2i\fP pixels are filled in each column that is rasterized, -where \f2i\fP is the rounded value of _param1. -Otherwise, -\f2i\fP pixels are filled in each row that is rasterized. -.P -If antialiasing is enabled, -line rasterization produces a fragment for each pixel square -that intersects the region lying within the rectangle having width -equal to the current line width, -length equal to the actual length of the line, -and centered on the mathematical line segment. -The coverage value for each fragment is the window coordinate area -of the intersection of the rectangular region with the corresponding -pixel square. -This value is saved and used in the final rasterization step. -.P -Not all widths can be supported when line antialiasing is enabled. If an -unsupported width is requested, the nearest supported width is used. -Only width 1 is guaranteed to be supported; others depend on the -implementation. Likewise, there is a range for aliased line widths as well. -To query the range of supported widths and the size -difference between supported widths within the range, call _cmnd(Get) -with arguments _const(ALIASED_LINE_WIDTH_RANGE), -_const(SMOOTH_LINE_WIDTH_RANGE), _const(SMOOTH_LINE_WIDTH_GRANULARITY). -.SH NOTES -The line width specified by _cmnd is always returned when _const(LINE_WIDTH) -is queried. -Clamping and rounding for aliased and antialiased lines have no effect -on the specified value. -.P -Nonantialiased line width may be clamped to an implementation-dependent -maximum. Call _cmnd(Get) with _const(ALIASED_LINE_WIDTH_RANGE) to -determine the maximum width. -.SH ERRORS -_const(INVALID_VALUE) is generated if _param1 is less than or equal to 0. -.P -_const(INVALID_OPERATION) is generated if _cmnd -is executed between the execution of _cmnd(Begin) -and the corresponding execution of _cmnd(End). -.SH ASSOCIATED GETS -_cmnd(Get) with argument _const(LINE_WIDTH) -.br -_cmnd(Get) with argument _const(ALIASED_LINE_WIDTH_RANGE) -.br -_cmnd(Get) with argument _const(SMOOTH_LINE_WIDTH_RANGE) -.br -_cmnd(Get) with argument _const(SMOOTH_LINE_WIDTH_GRANULARITY) -.br -_cmnd(IsEnabled) with argument _const(LINE_SMOOTH) -.SH SEE ALSO -_cmnd(Enable) |
