Efl.Gfx.Mapping.mapping_coord_absolute

Description

A point's absolute coordinate on the canvas.

This sets/gets the fixed point's coordinate in the map. Note that points describe the outline of a quadrangle and are ordered either clockwise or counter-clockwise. Try to keep your quadrangles concave and non-complex. Though these polygon modes may work, they may not render a desired set of output. The quadrangle will use points 0 and 1 , 1 and 2, 2 and 3, and 3 and 0 to describe the edges of the quadrangle.

The X and Y and Z coordinates are in canvas units. Z is optional and may or may not be honored in drawing. Z is a hint and does not affect the X and Y rendered coordinates. It may be used for calculating fills with perspective correct rendering.

Remember all coordinates are canvas global ones as with move and resize in the canvas.

This property can be read to get the 4 points positions on the canvas, or set to manually place them.

Keys

  • idx - ID of the point, from 0 to 3 (included).

Values

  • x - Point X coordinate in absolute pixel coordinates.
  • y - Point Y coordinate in absolute pixel coordinates.
  • z - Point Z coordinate hint (pre-perspective transform).
