Edit the point symbol

The point symbols managed in the Marker Symbol Selector can be further edited to meet new requirements. Point symbols in Marker Symbol Library can be roughly divided into three categories: 2D vector point symbols, 2D grid point symbols and 3D markers. These three types of point symbols are edited in different places: 2D vector point symbols are edited in Marker Symbol Editor; 2D grid point symbol editing is done in the Raster Symbol Editor.

When editing a point symbol in a Marker Symbol Library:

  1. First, in the Marker Symbol Selector, select the point symbol to be edited;
  2. Then, click the Edit button in the Selector; or double-click the left mouse button on the point symbol to be edited to open the corresponding editor;
  3. In the editor, click the OK button when you have finished editing the symbol. Due to the different types of edited point symbols, the opened symbol editor and the editing contents of the symbols are also different, which are described below.

Edit 2D Vector Point Symbol

In the Marker Symbol Selector, if the selected point symbol to be edited is a vector point symbol, after clicking the Edit button, the Marker Symbol Editor will be opened, and the selected point symbol will also appear in the Marker Symbol Editor. You can use the editing function provided by the Marker Symbol Editor to further edit the point symbol as required. After editing, click the OK button. For how to edit the point symbol through the Marker Symbol Editor, see the Marker Symbol Editor User's Guide section.

The editing result of the point symbol in the Marker Symbol Library can be finally saved only by saving the symbol library file or the Workspace where the symbol library resource is located.

Edit 2D Grid Point Symbol

Editing operations for 2D grid point symbols include editing the attributes of the symbol, such as Symbol Number, Symbol Name, Symbol Origin (that is, Symbol Anchor).

  1. In the selector, select the grid point symbol to be edited;
  2. Click the Edit button, or double-click the left mouse button on the selected point symbol to open the Raster Symbol Editor;

    Here, you can modify the number of the Raster Symbol, the Symbol Name, and change the position of the symbol origin.

  3. After editing the Raster Symbol, click the OK button.

The symbol origin, or symbol anchor, sets the location of the center point of the Raster Symbol. When symbolizing a point object, the origin (anchor) is located at the coordinate point of the point object.

To set or edit the origin position of the Raster Symbol, in addition to entering or adjusting the values in the two value boxes behind the symbol origin, you can also use the Set Origin button to reset the origin of the Raster Symbol as follows:

  1. In the Raster Symbol Editor, click the Set Origin button;
  2. In the symbol editing area of the Grid Selector, move the mouse and click the mouse at the desired location to set the location as the origin of the Raster Symbol.

In addition, you can make a certain color of the Raster Symbol transparent, that is, change the area covered by the selected color in the Raster Symbol into a transparent area by clicking the Transparent Processing button as shown in the following figure, and then, Click the mouse on the color that needs to be transparent. At this time, the area covered by the color becomes transparent.
