Methods in detail

Image2DScalar ( in Image2DScalar other )

copy constructor

---

Image2DScalar ()

Default constructor. Sets up the statistics register.

---

Image2DScalar Image2DScalar.clone? ()

clone method

---

StatisticRecord[] Image2DScalar.getStatistics? ()

Implementation of StatisticSource interface’s ‘getStatistics()’.

---

Image2DScalar.resize! ( in UInt32 width, in UInt32 height )

Resize the image allocating space for pixel storage.

width	The new width of the image
height	The new height of the image

---

Scalar Image2DScalar.sample? ( in Scalar u, in Scalar v )

Samples the image pixels, returning a bi-linearly interpolated pixel value.

u	The u param to sample the image. Should range between 0.0 and 1.0
v	The v param to sample the image. Should range between 0.0 and 1.0

---

Image2DScalar.setPixel! ( in Integer uindex, in Integer vindex, in Scalar pixelValue )

Sets a new pixel value

uindex	the index of the pixel in u
vindex	the index of the pixel in v
pixelValue	the new value for the pixel
