ImageTransformation

ImageTransformation
gives an image in which each pixel at position corresponds to the position in image.
ImageTransformation
gives an image of the specified size.
MORE INFORMATION
  • The bottom-left corner of the image corresponds to coordinates by default. Other coordinate systems can be specified by setting the PlotRange and DataRange options.
AspectRatioAutomaticaspect ratio of the output image
DataRangeAutomaticrange of coordinates in the original image
PlotRangeAutomaticrange of coordinates in the resulting image
PaddingBlackpadding method
ResamplingAutomaticresampling method
  • The range of the coordinate system for the input image is assumed to be , where a is the aspect ratio. Other coordinate systems can be specified by setting the DataRange option.
Automaticrange , where a is the aspect ratio
{{left,right},{bottom,top}}explicit coordinate ranges
Fulltrue pixel range
  • The coordinate system of the resulting image is specified by the PlotRange option, which takes the same settings as DataRange.
  • PlotRange->All tries to find a plot range that includes the images of all pixels in the input image.
  • For possible size specifications, see the reference page for ImageResize.
