PreserveAspectRatio When False the image is stretched to fit the space exactly. When True the image is padded or cropped to maintain its aspect ratio.
HorizontalAlignment Defines how the image should be aligned horizontally when PreserveAspectRatio is True:
  • Left
  • Center
  • Right
HorizontalAlignment has no effect when PreserveAspectRatio is False.
VerticalAlignment Defines how the image should be aligned vertically when PreserveAspectRatio is True:
  • Top
  • Center
  • Bottom
VerticalAlignment has no effect when PreserveAspectRatio is False.
ImageFitMode Defines how the image should should fill the available space when PreserveAspectRatio is True:
