Reading RGB image channels
Each RGB channel stores intensity values from 0 to 255. In grayscale mode, brighter areas contain more of that channel. Color mode keeps the selected component in red, green, or blue while setting the other two components to zero.
Câu hỏi thường gặp
Why do channel images look grayscale?
Grayscale makes channel intensity easier to compare: white is 255 and black is 0.
Does the splitter keep transparency?
Yes. Each output PNG keeps the source alpha value for every pixel.
