Feature Table Properties

SIS uses named Feature Table objects to control the display, e.g. Pen, Brush, Symbol, etc., of feature coded items.

The properties of individual feature codes within a Feature Table are set and queried using the SIS_OT_FTABLE constant and the GetFlt/GetInt/GetStr/GetProperty and SetFlt/SetInt/SetStr/SetProperty methods. The nObject& argument must be the feature code being queried or edited. The Feature Table must first have been loaded using the LoadFeatureTable method.

Feature Table Properties

• Brush: _brush$
  The Brush used to fill any area covered by an item with this feature code.
  
  
• Description: _DESC$
  A textual description of the feature code. MapTips™ often display the description.
  
  
• Feature code: _FC&
  The feature code itself.
  
  
• Font: _font$
  The font used to draw text in any items with this feature code. SIS will look for a True-Type font which has the same name.
  
  
• Layer: _layer$
  The layer name of this feature code.
  
  
• Level: _level&
  The level within an overlay on which to draw an item with this feature code.
  
  
• Maximum scale: _scalemax#
  The highest reproduction scale at which an item with this feature code will be drawn. If you set this value to 1000, and then zoom out to 1:2000 the item will become invisible.
  
  This value is stored internally using a low precision byte. The value you enter will be rounded to the nearest valid value automatically.
  
  
• Minimum scale: _scalemin#
  The lowest reproduction scale at which an item with this feature code will be drawn. If you set this value to 100, and then zoom out to 1:50 the item will become invisible.
  
  This value is stored internally using a low precision byte. The value you enter will be rounded to the nearest valid value automatically.
  
  
• Parent feature code: _ParentFC&
  The parent feature code of this feature code, allowing hierarchical trees of feature codes to be constructed.
  
  
• Pen: _pen$
  The Pen used to draw any item with this feature code.
  
  
• Point height: _point_height&
  The height in "points" at which to draw text items with this feature code.
  
  
• Symbol: _shape$
  The Symbol used to draw any point item with this feature code.
  
  
• Sort by name: _bAlphabetic&
  This property defines whether features are ordered by feature code or by name alphabetically. The property applies to the entire feature table and will therefore only work if feature code = 0.
  
  
• Text fill brush:_textFillBrush$
  Brush for text fill.
  
  
• Text pen outline: _textOutlinePen$
  Pen for text outline.
  
  
• Text bold: _text_bold&
  Flag to set bold text.
  
  
• Text italic: _text_italic&
  Flag to set italic text.
  
  
• Text underlined: _text_underlined&
  Flag to set italic text.  
  
  
• Text box: _text_box&
  Flag to set box around text.
  
  
• Text opaque: _text_opaque&
  Flag to set opaque.  
  
  
• Text outline: _text_outline&
  Flag to set outline.
