Parameters

Parameter Name Description Type Supported Values Default Value
input
inputImage
The input image. Image Binary, Label, Grayscale or Multispectral nullptr
input
axis
The symmetry type.
X_AXIS The flip transformation is relative to an axis parallel to X. The result is given by: $$ O(x,y)=I(x,N+1-y) $$ where N is the Y image size.
Y_AXIS The flip transformation is relative to an axis parallel to Y. The result is given by: $$ O(x,y)=I(M+1-x,y) $$ where M is the X image size.
CENTER The flip transformation is relative to the center of the image. The result is given by: $$ O(x,y)=I(M+1-x,N+1-y) $$ where M is the X image size and N is the Y image size.
Enumeration X_AXIS
output
outputImage
The output image. Its dimensions and type are forced to the same values as the input. Image nullptr
