We use “opacity” when referring to the alpha channel because that’s what the alpha channel measures. A high alpha value makes the pixel more opaque, a low value makes it more transparent (less opaque). Saying that a pixel with “transparency 0” is transparent and one with “transparency 255” is opaque would be far more confusing.
- twelvechairs 5y agoYes and no. Yes opacity is what is in the alpha channel. But all im saying is that it would be easiest for all to think of as inverse of transparency, and this is how documentation should describe it, otherwise people make weird assumptions like OPs. Its stored as opacity rather than transparency for minor performant reasons not because its a different concept or better way to think of it
