Anchor Position
Being aware of Cursor Position is important for choosing the anchor position of a
symbol. The anchor is the pixel position on the symbol that corresponds to the
geographic coordinate of the point selected on the map when the symbol is placed.
Any newly created symbol, whether imported, pasted or dragged into the XSym
Symbol Editing Grid, has a default position of center anchor.
XSym lets you change the anchor position of your symbol.
To Select the Anchor Position
Use the following steps to select the anchor position of a symbol.
1. Once your symbol is created, click the Anchor Position
button.
When you pass your pointer over the Symbol Editing Grid, it changes to a
small cross hair (plus sign).
2. Click the pixel grid within the symbol to position your anchor.
The anchor location pixel coordinate numbers display after the position text to
the right of the Anchor Position button. The large cross hair in the Symbol
Editing Grid moves from its default anchor position to the new anchor
position.
To Center the Anchor Position
Click Center Anchor to place the anchor point in the exact center of the Symbol
Editing Grid.
Cursor Position
Any symbol created in XSym is 24 x 24 pixels square. Each of these pixels is
represented in the Symbol Editing Grid. When you move your cursor over the
Symbol Editing Grid, the cursor position by pixel number displays to the right of the
Cursor Position text next to the Image Preview (as shown below).
Image Preview and Cursor Position
As you move the cursor over the grid, the numbers update according to where you
are in the 24 x 24 grid. The first number in the above sample, 16, refers to the
number of pixels across (the X coordinate) from the upper left corner of the grid,
beginning with zero. The second number, 14, refers to the number of pixels down
(the Y coordinate) from the upper-left corner of the grid, beginning with zero.
