DTM Group Key

With n4ce, you can group triangles together to highlight specific areas of a DTM using DTM groups.  The Table Group Key option allows you to create a key that shows which triangles are assigned to which groups.  When selected, the dialog box shown below will be displayed.

The Groups group specifies which groups to include in the key.  If the All radio button is set, all the groups will be included.  If the Valid radio button is set, only those groups that have one or more triangles assigned to them will included.

The Style group allows you to specify what you wish to appear in the swatch for each group.  If Fill Pattern is set, a solid fill will be created.  If Hatch Style is set, a cross-hatch using the pattern specified in the combo box will be used.  In both cases, the colour used will be that of the foreground colour of the fill style assigned to the group.

The Swatch Size group specifies the size of the swatch created in the key for each group.  The Width and Height fields specify the width and height of the rectangle in millimetres.

The Attributes group specifies the remaining defaults for the key.  These are the layer on which it will be created, the pen used for the borders around the swatches and the text style for the group names.  The pen used for the group names will be the same as that for the swatch borders.
