Question

I’m playing with pixels in an image..

What i have:

int w; // width
int h; // height
unsafe private int **pData; // pixel data

i want to be able to set pData’s height and width… so something like the following:

 pData = new int*[w]; 

 for(int x = 0; x<w; x++)
    pData = new int*[h]; 

this causes an error though (“cannot implicitly convert int[] to int**). How would i go about doing this in C#? I know this will work in C and C++…

I guess what i’m looking for is an equivalent to the above in C# … as that is written in C++

Answer 1

So you just want a pixel grid?

In C# you could just use multidimensional arrays or an array of arrays, e.g.

private int[,] pixelData = new int[w, h];

// (Might have confused some variables here)
private int[][] pixelData = new int[w][];
for (int i = 0; i < w; i++) pixelData[i] = new int[h];
