GENERATE_LABEL_LAYER

Overview

  • FILENAME - required parameter that identifies the loaded layer that will be the source for the label layer.
  • GROUP_LABEL_LAYER_WITH_SOURCE - indicates whether or not to put the label layer and its source layer into a new group in the Control Center.
  • LABEL_FIELD - specifies the name of the attribute field to use as the label attribute for the features in the file. By default the attribute-based labeling will only be applied to those features that don't already have a label, but if the LABEL_FIELD_FORCE_OVERWRITE attribute is set to YES then all features will have their labels replaced. If you want to build the label from multiple attributes, separate them with '>+<' in the file, like LABEL_FIELD='RD_PREFIX>+<RD_NAME>+<RD_SUFFIX'.
  • LABEL_FIELD_SEP - specifies the attribute separator to use when building a label from multiple attributes. This can be any character(s). For example LABEL_FIELD_SEP='-' will insert a dash between each attribute. Use hex codes to add any non-printable characters, such as LABEL_FIELD_SEP='0x20' to add a space.
  • LABEL_CUSTOM_DEF - specifies a custom free-form string describing how to form the display labels for this layer. This can include embedded attribute values as %ATTR_NAME%.
  • LABEL_FIELD_FORCE_OVERWRITE - specifies that the LABEL_FIELD or LABEL_CUSTOM_DEF attribute value should be applied to all feature labels, not just those that don't already have labels. Use LABEL_FIELD_FORCE_OVERWRITE=YES to enable.
  • SHOW_LABELS - specifies whether or not labels are shown for features in this layer, assuming they would be otherwise shown. The default is SHOW_LABELS=YES. Use SHOW_LABELS=NO to disable the display of labels for this layer regardless of other settings.
  • LABEL_PREFIX - specifies the prefix to prepend to attribute-based labels
  • LABEL_SUFFIX - specifies the suffix to append to attribute-based labels
  • LABEL_FORMAT_NUMBERS - specifies whether or not numeric attribute values should automatically have formatting applied to them. This is enabled by default. Use LABEL_FORMAT_NUMBERS=NO to disable numeric formatting and keep numeric values exactly as they are in the attribute list.
  • LABEL_PRECISION - value is an integer indicating the number of decimal digits to use. This applies to numeric labels.
  • LABEL_REMOVE_TRAILING_ZEROS - This removes the trailing zeros to the right of the decimal place in numeric labels. This can be specified by listing the parameter alone, or accepts boolean values.
  • LABEL_USE_SCIENTIFIC_NOTATION - Display the number in scientific notation. This accepts boolean values, or can be called by listing the parameter alone.
