Image_PlanarPixelInterpolation Class Reference

The class PlanarPixelInterpolation is used to compute a
SubPixelvalue on non integer Image coordinate
PlanarPixelInterpolation redefined a new method to compute a
SubPixel value .
To compute the value of a Image SubPixel, first we look
for the three nearest Image Pixels .
Then we compute the plane definition in the 3D space
composed by the Image Pixel coordinate and Pixel value
on Z axis .
The SubPixel value is the Z value of ( FX,FY ) point in the
three nearest Image Pixel defined plane .

virtual Standard_Boolean Interpolate (const Handle< Image_Image > &aImage, const Standard_Real X, const Standard_Real Y, const Standard_Integer LowerX, const Standard_Integer LowerY, const Standard_Integer UpperX, const Standard_Integer UpperY, Aspect_Pixel &RetPixel) const
 Redefined the method to compute SubPixel's value
on non integer Image coordinate.
LowerX,LowerY,UpperX,UpperY is the Image Min Max, it's used
to check if the SubPixel coordinate FX,FY is outside of
image.
Return True if Interpolation Succes.
Return False if the SubPixel is out from Image.

 Compute SubPixel's value on non integer Image coordinate for
DColorImage and ColorPixel.
LowerX,LowerY,UpperX,UpperY is the Image Min Max, it's used
to check if the SubPixel coordinate FX,FY is outside of
image.
Return True if Interpolation Succes.
Return False if the SubPixel is out from Image.

virtual Standard_Boolean Interpolate (const Handle< Image_DIndexedImage > &aImage, const Standard_Real X, const Standard_Real Y, const Standard_Integer LowerX, const Standard_Integer LowerY, const Standard_Integer UpperX, const Standard_Integer UpperY, Aspect_IndexPixel &RetPixel) const
 Compute SubPixel's value on non integer Image coordinate for
DIndexedImage and IndexPixel.
LowerX,LowerY,UpperX,UpperY is the Image Min Max, it's used
to check if the SubPixel coordinate X,Y is outside of
image.
Return True if Interpolation Succes.
Return False if the SubPixel is out from Image.
