ic_0307 The mode is intended for turn a raster image around of first point, indicated on vector (raster, matrix) map. The turn angle is set by two pairs of points:

- On the raster image;

- On a map.

 

Rotation without scaling mode expects from the user execution the following operations:

- To select the first point on a raster, to specify an appropriate point on a map;

- To select the second point on a raster, to specify an appropriate point on a map.

 

During a choice of points there is a possibility to control  the displaying a processed raster relative to the map. To change the display of the raster over/under the map, use the R button on the keyboard.

After a choosing the first pair of points (on the raster and on the map) the raster shifts to the specified point on the map.

After turn the image the binding of a raster varies. The copy of the initial raster  is  saved  with the same name, but with the extension *. ~ sw or *. ~ st.
