Name Type Argument Description
size Array.<number> <optional>

A array unit-less pixel value The array has size value.( number[width, height] )
Since:
  • 2.0.0
Inherited From:
Returns:

If there is an argument, then it returns itself to provide method chaining. In case of no argument, it returns an array including two unit-less pixel values, which means width and height. (for example, [100,100] means width : 100px, height: 100px).

Type
caph.module.renderer.View | Array
Example
var View = caph.module.renderer.View;
 var view = new View();
 view.size([100, 100]);

skew(x, y) → {caph.module.renderer.View|Array}

  • 2.0.0
Inherited From:
Returns:

If there is an argument, then it returns itself to provide method chaining. In case of no argument, it returns an array including two unit-less degree values, which means x and y skew.

Type
caph.module.renderer.View | Array
Example
var View = caph.module.renderer.View;
 var view = new View();
 var curSkew = view.skew();
 view.skew(curSkew[0] + 30, curSkew[1] + 30);
