MapTextLabeller
注意:的MapTextLabeller transformer is available as an extra-cost package from Safe Software.Please contactsales@safe.comor call 604-501-9985.
Creates text labels for features using the MapText Label Manager.
Input Ports
The input ports are dynamically generated via the规则配置parameter.
Output Ports
The output ports are dynamically generated via the规则配置parameter.
For each configured layer with name
The text labels will be output through the
Features for which a label could not be placed will be output through the
Parameters
Specifies the format used for the text labels.
Specifies the size of the text labels.The specified value represents the size on the ground that the label would occupy if a 1-point sized font were used.
If this parameter is enabled, the color specified by the feature'sfme_colorattribute will be used for the labelling.
If this parameter is not enabled, or the feature has nofme_colorattribute, then the color specified in规则配置will be used for the labelling.
Specifies which layers are to be labelled and how the labelling will be performed.
Usage Notes
The following steps are typically used when specifying the Rule Configurations parameter:
- Use the Import button to choose which layers and attributes are to be labelled.
- Click the Configure button to bring up the Label Manager dialog.
- For each layer to be labelled, select the geometry type (Point, Line, Polygon) of the feature from the Feat Type column.If the geometry type remains unselected, this layer can continue to be used as an obstacle.
- Click the Style button to specify what text should be displayed for the selected layer.
- Ensure that the Label checkbox is selected.
- Select the Obstacle checkbox if labels should not overlap features in the selected layer.
- Click the Rule button to customize the rules used to determine how the labels are placed.
For more information on label configuration, see theLabel Manager documentationprovided by MapText, Inc.请注意 that some Label Manager features, such as shared rules, are not supported by the MapTextLabeller.
TheMapTextStylercan be used with this transformer to specify no-label zones around features.
的MapTextLabeller automatically deaggregates features and attempts to label the individual pieces if they meet the labelling criteria.For more control over how labelling of aggregates is done, it is recommended that aggregates are split apart and possibly recombined prior to the MapTextLabeller, using transformers such as theDeaggregatorandAreaAmalgamator.
注意:的MapTextLabeller requires theMicrosoft .NET Framework 4to be installed.
Some of the target formats have the following specific issues:
If colors are set within the MapTextLabeller, the MicroStation writer will try to select the closest color from the seed file.To set colors properly, the desired font number from the seed file can be used for the Index Color parameter in the DGNStyler.
TrueType fonts should be specified in the seed file, since MapTextLabeller only uses this type of font.The FMEigds_fontformat attribute must be set to the font number from the seed file.Theigds_fontattribute can be set using an AttributeCreator, ValueMapper or another suitable transformer.
There is no color for shields and leaders (fme_color/fme_fill_color doesn't work).
It is not possible to write composite leaders to writer (a leader that is an aggregate of a polyline and filled polygon).
There is no color for shields and leaders (fme_color/fme_fill_color doesn't work).
It is necessary to manually set the Nominal scale and scaling to Paper in the GeoMedia workspace.

Editing Transformer Parameters
Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace.More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers.To access a menu of these options, clickbeside the applicable parameter.For more information, seeTransformer Parameter Menu Options.
