bool deleteChartParams | ( | TeDatabase * | db,
|  | TeAppTheme * | theme
| ) |  |

Deletes the chart parameters of a theme in the database

Parameters:

  db | pointer do a TerraLib database
  theme | pointer to a theme as defined by TerraView

string deletePointedObjects | ( | TeTheme * | theme,
|  | TeBox & | box
| ) |  |

Delete the objects of a layer that are pointed in a theme

Parameters:

  theme | pointer to the extended theme were the objects are pointed
  box | to return the bounding box that contains the objects that were deleted

Returns:
  the error message of the database when the function fails

bool deleteTextVisual | ( | TeLayer * | layer | ) |

Removes tables that contains the visual of texts associated to a layer

Parameters:

  layer | pointer do a TerraLib layer

bool generateCountLegends | ( | TeAppTheme * | appTheme,
|  | string | table,
|  | string | field
| ) |  |

generate Count legends

bool generateTextUsingCentroid | ( | TeTheme * | theme,
|  | const std::string & | objectId = `""`
| ) |  |

This function generates the position of text labels.

It calculates the label position using the center of geometry box. This coordinate is calculated as follows:

- If the geometry is a polygon, the label is located at the polygon box center. If this coordinate isn't within the polygon, recalcultates coordinate. The new label position will be the polygon centroid.
- If the polygon has islands, the label position will be located within the polygon with greater area.
- If the geometry is a line, the label is located ate the line box center. If this coordinate isn't located at the line, recalculates the coordinate. The new label position will be the center point of the line.
- If the geometry is a point, the label will be the point.

Parameters:

  theme | The theme to generate labels positions.
  objectId | Object identifier. This parameter is used, if the label position must be generated for a particular object.

Returns:
  True if everything is ok, false if something fails.
