Editing of image for line objects

The lines used in the classifier can be submitted as a combination of the following primitives: line,  dashed line, dashed line with offset, vector symbol or vector on line.

Parameters of a line is a color and line thickness.

Parameters of a dashed line is a color, thickness of a line, dot length and blank length. Dot length  is a length of the drawn piece. Blank length is a distance between two pieces. If the dot length is 1, we receive a dashed line.

1 - Double line. 2 - Dashed line on a double line. 3 - Line on a dashed line.

4 - Double line on a dashed line. 5 - Line on the displaced dashed line.

Dashed line with offset is drawing as usual, but with displacement. If displacement is 0, a dashed line will adjoin to an axis on the right. If displacement is positive, a dashed line will be displaced from an axis to the right. At negative displacement the dashed line is displaced to the left.

Combining a line and a dashed line it is possible to receive objects of a different kind.

Vector symbol is used for small line objects (metrics from 2 points).

Vector on a line are used for creation of complex line objects, which image includes badges except a line. By pressing Parameters button the dialogue Decoration of line object is called.

From above in Decoration of line object dialogue a window for displaying the general line view is located.

Below there are two windows for decoration of extreme points of each piece (Begin and  End). Further there are two windows for decoration of the first and the last points of a line (Begin and End). Below there are two windows for filling a line by the metrics (First symbol, Second symbol and distance between them).

By pressing in any of these windows, dialog Symbol editing is called. In the dialog it is possible to enter, modify, and also to delete a vector symbol. All windows can be filled if necessary.

1 - decoration of line. 2 - decoration along segment (by one object).

3 - decoration of segment (by two alternating objects).

4 - decoration by points.

For a line at which vector symbols are located on each segment, fill in windows Decoration of  polyline (for example, for the image of electric mains).

If the beginning or the end of object line should be marked (the bridge, the tunnel), Decoration of  line is convenient to use.

For objects located uniformly along line use Decoration along line windows.

It is possible to enter one or two objects alternating among themselves, situated on the set distance from each other (for example, oil pipelines, communication lines, embankments).

For deleting any of vector symbols it is necessary to enter into editing of corresponding vector object, to clear a field and to save the made changes.

By pressing Save button, vector decoration of line will be written down. Changes can be cleaned by pressing Cancel button.
