Image

A Image is a read-only raster image. Image items can only be created by Plug-in Datasets. The image is regenerated by the Plug-in Dataset every time it is drawn. This means that it can be very high resolution, and use anti-aliasing.

Item Properties

Properties

• Area: _area#
  The area covered by the item in square metres.
  
  
• Clockwise: _bClockwise&
  Is the item geometry defined in a clockwise direction?
  
  
• Height: _height&
  The number of rows in the Bitmap item.
  
  
• Name: _name$
  The name of the image source of a Image item.
  
  
• Number of edges: _numedges&
  The number of edges in a geometrical shape.
  
  
• Number of loops: _numloops&
  The number of loops used by a Polygon item. Most Polygon items have only one loop. However, any holes or islands will be stored as extra loops.
  
  
• Splinter factor: _splinter#
  The splinter factor of the Polygon. A circle has a splinter factor of 1. A very long and thin area could have a splinter factor of 100. Polygon items with large splinter factors are often produced by overlapping lines which are almost by not quite the same.
  
  
• Width: _width&
  The number of pixels in each row of a Bitmap.
