Attributes

Description

flipH (Horizontal Flip)

Horizontal flip. When true, this attribute defines that the group is flipped horizontally about the center of its bounding box.

[Example: The following illustrates the effect of a horizontal flip.

DocumentFormat.OpenXml.Drawing.TransformGroup-imag

end example]

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

flipV (Vertical Flip)

Vertical flip. When true, this attribute defines that the group is flipped vertically about the center of its bounding box.[Example: The following illustrates the effect of a vertical flip.

DocumentFormat.OpenXml.Drawing.TransformGroup-imag

end example]

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

rot (Rotation)

Rotation. Specifies the clockwise rotation of a group in 1/64000 of a degree.

The possible values for this attribute are defined by the ST_Angle simple type (§20.1.10.3).

[Note: The W3C XML Schema definition of this element’s content model (CT_GroupTransform2D) is located in §A.4.1. end note]
