Magic ++ RGB颜色值

Question

有谁知道为什么Magic ++给我的RGB值小于1？

Answer 1

The maximum RGB component value in Magick is 1 and the minimum is 0. So the values should be between 0 and 1. For example, RGB values of (0.5, 0.5, 0.5) represents a grey, (1.0, 0, 0) would be a pure red, etc.

Check out the documentation . You may also find this of interest, it discusses what typically happens when the RGB component values are between 0 and 1 (multiplied by 255).

Answer 2

我不知道特定的库，但是RGB通常表示为0到1之间的浮点值以及0到255之间的无符号字节值。
