20.1.9.18 prstGeom

This element specifies when a preset geometric shape should be used instead of a custom geometric shape. The generating application should be able to render all preset geometries enumerated in the ST_ShapeType list.

[Example: Consider the scenario when a user does not wish to specify all the lines and curves that make up the desired shape but instead chooses to use a preset geometry. The following DrawingML would specify such a

case.

<p:sp>
  <p:nvSpPr>
    <p:cNvPr id="4" name="My Preset Shape"/>
    <p:cNvSpPr/>
    <p:nvPr/>
  </p:nvSpPr>
  <p:spPr>
    <a:xfrm>
      <a:off x="1981200" y="533400"/>
      <a:ext cx="1143000" cy="1066800"/>
    </a:xfrm>
    <a:prstGeom prst="heart">
    </a:prstGeom>
  </p:spPr>
</p:sp>

The output shape rendered by this DrawingML is shown above. end example]

Attributes

prst (Preset Shape)

Specifies the preset geometry that is used for this shape. This preset can have any of the values in the enumerated list for ST_ShapeType. This attribute is required in order for a preset geometry to be rendered.

[Example: Consider the sample DrawingML below.

    <p:sp>
        <p:nvSpPr>
          <p:cNvPr id="4" name="Sun 3"/>
          <p:cNvSpPr/>
          <p:nvPr/>
        </p:nvSpPr>
        <p:spPr>
          <a:xfrm>
              <a:off x="1981200" y="533400"/>
              <a:ext cx="1143000" cy="1066800"/>
          </a:xfrm>
          <a:prstGeom prst="sun">
          </a:prstGeom>
        </p:spPr>
    </p:sp>

In the above example a preset geometry has been used to define a shape. The shape utilized here is the sun shape. end example]

The possible values for this attribute are defined by the ST_ShapeType simple type (20.1.10.56).
