L.5.2.2.1 CoordOrigin and CoordSize Attributes

These attributes define the relative coordinate space of a shape. This space is scaled up or down to match the specified Width and Height of the shape. Coordinates in the Path attribute (or element) are relative to the space defined by CoordOrigin and CoordSize, so the Path definition never needs to change simply to scale the shape.

For example:

coordorigin="0,0"
coordsize="200,200"

Extents of local space are (0,0) to (200,200)

coordorigin="-100,-100"
coordsize="200,200"

Extents of local space are (-100,-100) to (100,100)

This local space definition affects the position of the shape. Changing the CoordOrigin translates the shape within the local space. Changing the CoordSize affects the size of the shape by changing the size of the local space relative to the shape’s Width and Height.

For example:

coordorigin="0,0"
coordsize="500,500"
style="position:absolute;top:0;left:0;width:100pt;
  height:100pt"
coordorigin="-250,-250"
coordsize="500,500"
style="position:absolute;top:0;left:0;width:100pt;
  height:100pt"
coordorigin="0,0"
coordsize="250,250"
style="position:absolute;top:0;left:0;width:100pt;
height:100pt"
