markuswaeger Posted December 20, 2016 Share Posted December 20, 2016 Hi. In Affinity Photo 1.5 the Info panel shows a Value A for RGB und HSL and ∝ for LAB. What purpose does this have? Thanks.

- S - Posted December 20, 2016 Share Posted December 20, 2016 That's the alpha channel value. In RGB:0 = fully transparent127 = Half transparent255 = fully opaque In LAB/HSL/Greyscale:0% = fully transparent49% = Half transparent100% = fully opaque To see it for yourself: 1) Open a new document2) Go to Document > Transparent Background (to toggle background to transparent)3) Use the Rectangle Tool to drag a rectangle on the canvas4) As you change the layer opacity of the rectangle, the Alpha value in the Info Pane will change accordingly Quote Link to comment Share on other sites More sharing options...
Alfred Posted December 20, 2016 Share Posted December 20, 2016 49% = Half transparent Half transparent should be 50%.
