rpaul Posted April 30, 2019 Share Posted April 30, 2019 So, It appeares that I should be able manipulate the alpha channel of a bitmap layer in curves, adjusting the opacity. And I was able to adjust an image with the alpha set to fully opaque 255 downwards to make it more transparent, however, I wasn't able to increase the opacity of an image with a translucent alpha channel. Is there a reason for this? or am I doing it wrong? Thanks Quote Link to comment Share on other sites More sharing options...
Staff Dan C Posted May 2, 2019 Staff Share Posted May 2, 2019 Hi rpaul Sorry to hear you're having trouble. Could you please provide a screenshot of your layers panel? This sounds similar to a previously reported bug so I'd like to check! rpaul 1 Quote Please note - I am currently out of the office for a short while whilst recovering from surgery (nothing serious!), therefore will not be available on the Forums during this time.

rpaul Posted May 4, 2019 Author Share Posted May 4, 2019 Thanks for getting back to me Dan, So I uploaded three images of an AP file with two bitmapped sample layers and also the curves adjustment control showing three states. For the top layer I just selected the area outside of an oval and made the alpha channel (and text) more transparent. The center of the top layer text is still opaque. The first image shows the default state. The second image shows it when the slope is lowered to almost zero. The third image shows what happens when you raise the bottom end of the slope up close to maximum. My point here is that image 1 and 3 show no difference. What I've seen in other software is is that by raising the lower end of the curves upwards, the text outside the oval should become more opaque. I should also note that editing the center of the curves control doesn't seem to affect the image in a way that I would expect. Since I started this topic, I discovered another way to influence the alpha channel. So my life doesn't hang on solving this issue. Thanks.
