- image
- References the image that contains the region.
- xForm
- RasterRegionXForm object that contains information used to translate between display coordinates and image coordinates. If you specify null in this parameter, the scalar fields default to 1, the offsets default to 0, and the view perspective defaults to the image's view perspective.

Parameters
- image
- References the image that contains the region.
- xForm
- RasterRegionXForm object that contains information used to translate between display coordinates and image coordinates. If you specify null in this parameter, the scalar fields default to 1, the offsets default to 0, and the view perspective defaults to the image's view perspective.
Return Value
The perimeter length of the region.Run the Leadtools.ImageProcessing.Effects.EffectsUtilities.GetRegionPerimeterLength method on an image.

- This command works only on images having a region. If an image does not have a region the command returns the error: Not Initialized.
- This command supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.
Target Platforms: Silverlight 3.0, Windows XP, Windows Server 2003 family, Windows Server 2008 family, Windows Vista, Windows 7, MAC OS/X (Intel Only)
