|
* This extension provides for the addition of markers to the either end
|
* or the middle of a line, polyline, path, polygon.
|
*
|
* Markers may be either a graphic or arbitary text
|
*
|
* to simplify the coding and make the implementation as robust as possible,
|
* markers are not shared - every object has its own set of markers.
|
* this relationship is maintained by a naming convention between the
|
* ids of the markers and the ids of the object
|
*
|
* The following restrictions exist for simplicty of use and programming
|
* objects and their markers to have the same color
|
* marker size is fixed
|
* text marker font, size, and attributes are fixed
|
* an application specific attribute - se_type - is added to each marker element
|
* to store the type of marker
|
*
|
* @todo
|
* remove some of the restrictions above
|
* add option for keeping text aligned to horizontal
|
* add support for dimension extension lines
