I am teaching myself Go. I decided to try some computer vision stuff. First things first I was going to make an image histogram. I'm trying to get the color model so I know the intensity range of the pixels. When I print image.ColorModel() it gives me a cryptic hexidecimal output:
color model: &{0x492f70}
I couldn't find any explanation in the docs. I was expecting some sort of enum type thing that would map to a color model like, NRGBA, RGBA, etc.
What does that hexidecimal mean? What does the ampersand curly braces &{...} mean? Also what is the "N" in NRGBA I can't find anything about it.
