How to iterate pixels of image read by stbi.load

[pd-giz-dave]

Sorry, total novice here. I can't work out how to address the pixels read from stbi.load. I can see in the debugger I've got a voidptr in image.data but how do I use that? I know how to do it in C but not in V. I tried this:

for x in 0 .. image.width {
for y in 0 .. image.height {
pixel_address := unsafe { image.data + ((y * image.width + x) * image.nr_channels) }

But that throws a compiler error

Ah! I think I've worked it out:
`
struct Pixel {
r u8
g u8
b u8
a u8
}

mut pixels := []Pixel{len: image.width * image.height, cap: image.width * image.height}
unsafe {
pixels.data = image.data
}
`
In the debugger I can see a (flat) array of pixels :-)
