We have already seen how to create legends by scale with the new extension “Complex Legend”. Having this new extension installed in our gvSIG, we also will be able to create labels depending on the scale of our View.
Let´s refresh how it works…
As always, the first step is to go to labelling options: we open the properties window of the layer on which the label will be applied (right click on the layer name in the Table of Contents) and select the “Labelling” tab.
The definition of a sensitive scale label is located inside the panel “User defined labels“.
Regarding to the associated panel, its structure has not changed a lot, so it can be handled as usual; only it will be taken into account that the operation “Define classes of features and label each differently” and the new option “Multiple label by scale“ must be selected from he drop-down menu.
Once this option is selected, a new entry can be added defining the label to show, clicking on the field “Label expression” which has been added in the table.
The window shown is very similar to the one already known, unless a new tab at the top to bring up a form where the range of the scale on which the label will be visible will be indicated.
A functionality really interesting, don´t you think?
