User-defined Glyphs are defined in the database by GLYPH elements which are members of a Glyph Table (GLYTB) element. GLYPHs attributes are:
|
GLYNO: |
A system defined attribute that has a unique value within the Multiple Database (MDB). It is this number that is be used when the Glyph is used in conjunction with a user-defined Linestyle. |
|
REFSIZe: |
(Integer) The value that is mapped to the DECSIZ attribute value of the LINEST when the Glyph is used. Thus if a Glyph with REFSIZ 2000 consisting of a circle of diameter 1000 is used in conjunction with a LINEST with DECSIZ 6mm the result is a line with 3mm diameter circles. The database default value is 100. |

FUNCtion: |
Text attribute for descriptive purposes |
Note:
If you intend your glyph to be used as a terminal glyph on a line, the glyph will
be placed such that the origin of the glyph will coincide with the end point of the
line. For arrow-type glyphs, make sure the origin is at the point of the arrow.
GLYPH elements can own GLYCIR, GLYREC, and GLYOUT elements that represent circles, rectangles, and outlines. In addition to the basic attribute(s) that define their dimensions these glyph-primitive elements can be rotated and offset from the glyph origin, and can be solid-filled.
