14.1.2.21 stroke (Line Stroke Settings)

This element describes how to draw the path if something beyond solid line with a solid color is desired.  The attributes of the stroke element can be used to describe a powerful set of stroke properties.   Extensions to the VML stroke definition are encoded as sub-elements of stroke.

[Example:

<v:polyline points="0pt,0pt,50pt,0pt,50pt,35pt,15pt,35pt,
  15pt,15pt,75pt,15pt">
  <v:stroke startarrow="classic" endarrow="classic" 
    startarrowwidth="wide" endarrowwidth="wide" dashstyle="dashdot" 
    weight="2pt" color="teal" linestyle="thinThin"/>
</v:polyline>

Attributes

Description

althref (Alternate Image Reference)

Namespace: urn:schemas-microsoft-com:office:office

Specifies an alternate reference for an image in Macintosh PICT format.

[Example:

<v:stroke … althref="myimage.pcz" … >
</v:stroke>

end example]

The possible values for this attribute are defined by the W3C XML Schema string datatype.

color (Stroke Color)

Specifies the stroke color. Overrides the strokecolor attribute of a shape. Default is black. See the fillcolor attribute for a list of supported named colors.

[Example: The shape stroke is blue:

<v:shape … strokecolor="red" … >
  <v:stroke color="blue"/>
</v:shape>

end example]

The possible values for this attribute are defined by the ST_ColorType simple type (§15.1.2.3).

color2 (Stroke Alternate Pattern Color)

Specifies a second color for strokes, used when filltype is pattern. Default is no value.

When a pattern fill is used for the stroke, the stroke color is used in colored parts of the source image. The color2 defines an alternate color to use in place of black in the source image.

[Example: This unusual example is intended to demonstrate how the image and colors interact to create a patterned stroke. The yellow background shows transparency. The non-square shape and square image create an effective offset. The heavy stroke weight shows more of the image. The green shape fill shows how the stroke is overlaid on the shape.

<v:background fillcolor="yellow"/>
<v:shape style="width:60;height:50"
  strokecolor="red" fillcolor="lime"
  path="m 0,0 l 0,1000 1000,1000 1000,0 x e">
  <v:stroke filltype="pattern" weight="10pt"
    src="myimage.gif" color2="blue"/>
</v:shape>
DocumentFormat.OpenXml.Vml.Stroke-image002

end example]

The possible values for this attribute are defined by the ST_ColorType simple type (§15.1.2.3).

dashstyle (Stroke Dash Pattern)

Specifies the dot and dash pattern for a stroke. Default is solid. Pre-defined values are:

  • solid

  • shortdash

  • shortdot

  • shortdashdot

  • shortdashdotdot

  • dot

  • dash

  • longdash

  • dashdot

  • longdashdot

  • longdashdotdot

A custom-defined dash pattern can also be specified using a series of numbers. These define the length of the dash (the drawn part of the stroke) and the length of the space between the dashes. The lengths are relative to the line width: a length of 1 is equal to the line width. The endcap style is applied to each dash but the arrow style is not. The string defines the length of the dash then the length of the space. This can be repeated to form complex dash styles. The string should always contain a pair of numbers; if it contains an odd number of numbers the last is disregarded. 0 implies a dot that is fourfold symmetrical (with round end caps, this is a circle).

[Example:

<v:stroke dashstyle="0 2" weight="3pt"
  endcap="round">
</v:stroke>
DocumentFormat.OpenXml.Vml.Stroke-image003 
<v:stroke dashstyle="longdashdotdot"
