Filling of polygon object by conventional signs

The task is intended for filling the polygon object selected on a map by conventional signs.

The task works only with the selected polygon objects.

For filling the polygon object, which was selected on a map by point or vector signs it is necessary:

1. To choose a filling sign;

2. For filling polygon by vector sign with turn it is necessary to switch on Turn the filling sign button and to choose in the list of the classifier's semantics the semantics containing a bearing angle.

3. To set the order of object filling by a conventional sign - regular, chess or opposite-chess, chaos:

- Regular arrangement is an order at which conventional signs are arranged one against another on a horizontal and on a vertical through the intervals, which were set in dialogue.

- At arrangement of signs in the chess order the intervals between signs are automatically doubled and are placed one against another through a line.

- Opposite chess order assumes arrangement of conventional signs similarly to previous arrangement with that difference, that the first filling sign is displaced onto the established interval. The given opportunity is applied to drawing several images of signs on top of each other.

- For chaos arrangement the intervals between conventional signs are established according to an element value of a file of random numbers.

4. To set the size of a step of filling by the sign on a vertical and on a horizontal.

5.  If necessary to switch on Write to transaction register button.

6. To start the process of filling of polygon object by conventional point signs press Ok button.

When arranging filling signs by a polygon, automatic control of overlapping with other conventional signs or titles is performed. If at the calculated point of placement of the filling sign, another object falls into its dimensions, the filling sign at this point is not recorded. For those types of signs with which intersection is allowed, an object filter is set. For example, a meadow fill symbol can be placed on top of contours or polygons with a white background, and so on, and, therefore, these objects must be included in the filter selection.
