Some modes similar to a standard multimedia player are intended for demonstration of the data:

To demonstrate the data, there are several modes that are similar to the standard multimedia player:

- Begin;

- End;

- Previous;

- Next;

- Play (Start a continuous display (playback - multiplication));

- Stop;

- Pause.

 

The program is started from «Run Applications» dialog, «Thematic maps and diagrams» group, the «Data multiplication» task.

Customizing structure of the background and displayed data is carried out in the dialog window containing elements that allow you to manage the multiplication structure.

The data is arranged on two pages: Structure of background information and Structure of multiplication. On both pages, the data are divided by functional purposes: vector maps, raster maps, matrixes of elevations and matrixes of qualities. On page of Structure of background information the user has possibility to set structure of the information which will not change during animation. On the Structure of multiplication page, you set up the data for demonstration (multiplication) and the order in which they are displayed. At specifying background it is necessary to view all data types and to set necessary structure of data. Demonstration (viewing of map slides) is performed for the current data page, that is, at the same time one type of data can be displayed:

- Vector maps;

- Raster maps;

- Matrixes of elevations of a relief;  

- Matrixes of qualities.

 

It is impossible to execute simultaneously multiplication for both rasters and matrixes of quality. The composition of data multiplication can be changed by setting the corresponding flag. If the flag is set to true, the data participates in the multiplication process. The data for which the tag is not set, in the process of demonstration (multiplication) do not participate.

The order of demonstration (multiplication) is defined according to the list of the data top-down and is set by the user. The data located in the list higher are multiplied earlier of the data located in the list below. Initially, the program sets the order of the multiplication in accordance with the sequence order of the files in the Data list of maps. For changing the multiplication's order in the program there are stipulated two opportunities: with use of the mouse and with use of the keyboard. Using the mouse, the data lines (the name of the corresponding file) can be swapped. To do this, you need to move the cursor to the name of the desired file, click the left "mouse" button and, without releasing it, move the selected file to the desired location, release the "mouse" button. As a result, the data lines (file names) will be swapped. Using the keyboard, the corresponding row of data can be line-by-line raised and lowered. To do this, you must move the cursor to the name of the desired file, press the Shift key and, without releasing it, use the arrow keys to raise or lower the line.

Continuous playback (multiplication) is controlled by setting the delay of time between the displayed data and the number of multiplication cycles. The delay of time is set in milliseconds and is limited on a minimum by value of 100 milliseconds (0.1 seconds), and on a maximum by value of 10000 milliseconds (10 seconds).
