GetImageData as Color[]

[ChrisDill]

It shows a single element because mapPixels is a pointer and it shows the element it is pointing to. This does not mean there is only one element inside it.

You can see this by looping through the colors. Note there is a large number of colors in screendata.

unsafe
{
    var img = Raylib.GetScreenData();
    var img2 = Raylib.GetImageData(img);
    Color* mapPixels = (Color*)img2.ToPointer();

    for (int i = 0; i < img.width * img.height; i += 1)
    {
        Color color = mapPixels[i];
        // Use color here
    }

You could also use the newer Span which may be more suitable for your needs.

unsafe
{
    var img = Raylib.GetScreenData();
    var img2 = Raylib.GetImageData(img);

    Span<Color> colors = new Span<Color>(img2.ToPointer(), img.width * img.height);
    foreach (var color in colors)
    {
        // Use color here
    }
}

Thanks. I wasn't aware of Span or the Color* asterix reference in C#. That should've rang bells from using C.

Note there is a large number of colors in screendata.

Yes, I do have a small display though which may help it get through the work! :)
