Produces an SVG "clipPath" element with a "rect" element.

Syntax

clipPath_rect(
   id STRING,
   x STRING,
   y STRING,
   width STRING,
   height STRING )
  RETURNS om.DomNode
  1. id is the SVG object identifier.
  2. x is the X coordinate of the top-left corner of the clip rectangle.
  3. x is the Y coordinate of the top-left corner of the clip rectangle.
  4. width is the width of the clip rectangle.

Usage

This function creates a "clipPath" SVG DOM element using a rectangle as clipping shape.

A clip path can be used in a text or image element, to define the clipping borders.

The clip path element must be added to the defs node of the svg element.

To use a clip path in an SVG DOM element, set the "clip-path" attribute with the string generate by the url() function.

Example

DEFINE defs om.DomNode,
       clip_id STRING
...
LET clip_id = "clip_gh_1"
CALL defs.appendChild(
             fglsvgcanvas.clipPath_rect( clip_id, tx, ty, -1, sy )
     )
...
LET n = fglsvgcanvas.text( tx + 3, (ty + (sy/2) + 1), "Some text", NULL )
CALL n.setAttribute("clip-path", fglsvgcanvas.url("clip_gh_1") )
