5.7.4 Maintain aspect ratio
If the command Maintain aspect ratio is checked, the used work area and display area is of the same aspect
ratio as the used projection module, but the area reserved in the GUI to show the work and display area might
be of another aspect ratio. This means that there might be some extra space that is not used for the work and
display area; it is displayed in a dark Grey above and below (left and right) of the used area.
If the command is not checked the whole available area is used to display the work area and the display area,
but the aspect ratio is not necessarily the same as the one of the projection module.

5.7.5 Use vertical
The Use vertical command has only an effect if the command 4 by 3 aspect ratio or 16 by 9 aspect ratio is
checked, please refer to section
5.7.6 Aspect ratio below. If grid and display are of different aspect ratio, it might
not be possible to completely fill the work area with grid cells.
The cells can either be fit horizontally into the work area or vertically. Accordingly the space not covered by grid
cells is located on top and bottom of the work area or on its left and right side. By default the grid is horizontally
fit, if Use vertical is checked the grid is fit vertically into the work area. For the alignment of the grid please refer
also to section
5.7.7 Align grid.
The figure below shows a work area with a 4×3 resolution where the command 16 by 9 aspect ratio is checked.
On the left default settings are applied, Use vertical is not checked. Space not covered by the grid is above and
below the grid. On the right the command Use vertical checked. Now the space not covered by the grid is on the
left and right side.
