* PictureMarker allows the user to store and modify the properties that define a

74 |
* <b>picture marker symbol</b>.<p>
|
75 |
* <p>
|
76 |
* This functionality is carried out thanks to a tab (simple marker)which is
|
77 |
* included in the panel to edit the properities of a symbol (SymbolEditor)how is
|
78 |
* explained in AbstractTypeSymbolEditor.
|
79 |
* <p>
|
80 |
* First of all, in the above mentioned tab the user will have options to change
|
81 |
* the files from where the pictures for the symbol are taken (one for the symbol
|
82 |
* when it is not selected in the map and the other when it is done).<p>
|
83 |
* <p>
|
84 |
* Secondly, the user will have options to modify the pictures which had been
|
85 |
* selected before (width and offset) .
