QPDigitizerSquare Class Reference

Uniform rectangular pixel grid centered on the origin: pixel (i, j) covers $ [i\,p_x - S_x/2,\ (i+1)\,p_x - S_x/2] \times [j\,p_y - S_y/2,\ (j+1)\,p_y - S_y/2] $ with pitch $ p_x = S_x/n_x $, $ p_y = S_y/n_y $. More...

Detailed Description

Member Function Documentation

◆ GetPixel() [1/2]

QPPixel * QPDigitizerSquare::GetPixel ( const int  index)
virtual

Pixel by linear index, decomposed as (index / npixx, index % npixx) and forwarded to GetPixel(int,int).

Warning
The bounds check accepts index == npixx·npixy (it uses > instead of >=), and the quotient is validated against npixx although it ranges over the y count: the mapping is a clean bijection only for square grids (npixx == npixy).
Parameters
indexlinear pixel index
Returns
caller-owned new pixel, or nullptr when rejected

Reimplemented from QPDigitizerBase.

◆ GetPixel() [2/2]

QPPixel * QPDigitizerSquare::GetPixel ( const int  i,
const int  j 
)
virtual

Allocates and returns the pixel cell (i, j); every call produces a new QPPixel owned by the caller.

Warning
The upper-bound checks use fNpix < i rather than <=, so i == npixx and j == npixy are accepted and yield a one-past-the-end pixel outside the matrix.
Parameters
ipixel index along x
jpixel index along y
Returns
caller-owned new pixel, or nullptr when out of bounds
