The Main properties dialog of the scale bar
Item Properties panel provides the following functionalities
(see figure_composer_scalebar_ppt):
Primeiro, escolha o mapa ao qual a barra de escala será ligada.
Em seguida, escolha o estilo da barra de escala. Seis estilos estão disponíveis:
- Single box and Double box styles, which contain one or two lines of
boxes alternating colors.
- Middle, Up or Down line ticks.
- Numeric, where the scale ratio is printed (i.e., 1:50000).
The Units and Segments dialogs of the scale bar
Item Properties panel provide the following functionalities
(see figure_composer_scalebar_units):
In these two dialogs, you can set how the scale bar will be represented.
- Select the units you want to use with Scalebar units.
There are four possible choices: Map Units, the default one and Meters,
Feet or Nautical Miles which may force unit conversions.
- The Label unit multiplier specifies how many scalebar units per
labeled unit. Eg, if your scalebar units are set to “meters”, a multiplier of
1000 will result in the scale bar labels in “kilometers”.
- The Label for units field defines the text used to describe the
units of the scale bar, eg “m” or “km”. This should be matched to reflect the
multiplier above.
- You can define how many Segments will be drawn on the left and on
the right side of the scale bar.
- You can set how long each segment will be (fixed width), or limit
the scale bar size in mm with Fit segment width option. In the
latter case, each time the map scale changes, the scale bar is resized (and
its label updated) to fit the range set.
- Height is used to define the height of the bar.
The Display dialog of the scale bar Item Properties
panel provides the following functionalities (see
figure_composer_scalebar_display):
