Vector Graphics Object

Vector Graphics Object is the scene graph for managing vector graphics objects. User can create shape objects as well as fill objects and give them to the Evas_Object_Vg for drawing on the screen as well as managing the lifecycle of the objects, enabling reuse of shape objects.

Since Evas_Object_Vg is an Evas_Object all operations applicable to an Evas_Object can be performed on it (clipping, mapping, etc).

To create complex vector graphics you can create a hierarchy of shape and fill objects and give the hierarchy to Evas_Object which will be responsible for drawing and showing on the screen.

As the shape object and fill object (linear and radial gradients) have retain mode API, you only have to create it once and set the properties and give it to Evas_Object_Vg.

Any change in the properties of a shape or fill object are automatically notified to Evas_Object_Vg triggering a redraw to reflect the changes.

To create a vector path, you can give a list of path commands to the shape object using efl_gfx_shape_path_set() API.

Below are the list of features currently supported by Vector object.

  • Drawing SVG Path. You can construct a path by using api in efl_gfx_utils.h
  • Gradient filling and stroking. You can fill or stroke the path using linear or radial gradient.
    See also:
    Evas_Vg_Gradient_Linear and Evas_Vg_Gradient_Radial
  • Transformation support for path and gradient fill. You can apply affine transforms to path objects.
    See also:
    Eina_Matrix.
    Note:
    Below are the list of interfaces and classes that can be used to draw vector graphics using vector objects.
  • Efl.Gfx.Shape
  • Evas.VG_Shape
  • Evas.VG_Node
  • Efl.Gfx.Gradient
  • Efl.Gfx.Gradient_Radial
  • Efl.Gfx.Gradient_Linear

Example:

 vector = evas_object_vg_add(canvas);
 root = evas_obj_vg_root_node_get(vector);
 shape = efl_add(EVAS_VG_SHAPE_CLASS, root);
 Efl_Gfx_Path_Command *path_cmd = NULL;
 double *points = NULL;
 efl_gfx_path_append_circle(&path_cmd, &points);
 *       evas_vg_node_origin_set(shape, 10, 10);
 *       efl_gfx_shape_stroke_width_set(shape, 1.0);
 *       evas_vg_node_color_set(shape, 128, 128, 128, 80);
 *       efl_gfx_shape_path_set(shape, path_cmd, points);

Use this api if you know the end point's of the arc otherwise use more convenient function evas_vg_shape_append_arc_to()
See also:
evas_vg_shape_append_arc_to()
Parameters:
[in]objThe object.
[in]xThe x co-ordinate of end point of the arc.
[in]yThe y co-ordinate of end point of the arc.
[in]rxThe radius of arc in x direction.
[in]ryThe radius of arc in y direction.
[in]angleThe x-axis rotation , normally 0.
[in]large_arcDefines whether to draw the larger arc or smaller arc joining two point.
[in]sweepDefines whether the arc will be drawn counter-clockwise or clockwise from current point to the end point taking into account the large_arc property.
