NAME

markstyle - marker styles for <PLOT79> package

DESCRIPTION

Twenty different point markers are available in <PLOT79>. Markers always appear at a standard orientation and size, unrotated and centered at the current point, in the view surface plane, and of a size corresponding to hardware character size (about 0.01 on a scale of 0-1). Markers are not affected by world coordinate object modelling transformations or by perspective or rotation.

Markers 1-5 are standard in all CORE implementations. The remaining ones are implementation-dependent. Markers currently supported are taken from the Hershey font digitizations. The Hershey numbers are given in parentheses below for each marker. Marker heights have been adjusted to make them all roughly the same size. 

Code	Description	Hershey Number
1	Dot or period	(828)
2	Plus	(845)
3	Asterisk	(847)
4	Circle	(840)
5	X or Cross	(846)
6	Square	(841)
7	Triangle	(842)
8	Crosshair	(1284)
9	5-Pointed Star	(844)
10	6-Pointed Star	(868)
11	Swiss Cross	(866)
12	Bell	(869)
13	Paragraph	(1276)
14	Dagger	(1277)
15	Double Dagger	(1278)
16	Spade	(741)
17	Heart	(742)
18	Diamond	(743)
19	Club	(744)
20	Shamrock	(745)

Marker values less than 1 are treated as 1, and values greater than 20 are taken modulus 20.
