Vladimir78 Posted September 18, 2019 Share Posted September 18, 2019 Is it a bug or ? When i add a curve adjustment on a pixel layer i cannot see any curve into the curve box ( nowhere ! Nor RGB, Green, blue...) Thanks Quote Link to comment Share on other sites More sharing options...
Staff Gabe Posted September 19, 2019 Staff Share Posted September 19, 2019 Hi @Vladimir78, So that we are able to investigate bugs thoroughly could you please follow this link and update this post with the followings: https://forum.affinity.serif.com/index.php?/forum/71-bug-reporting/ Thanks, Gabe.

Vladimir78 Posted September 19, 2019 Author Share Posted September 19, 2019 Hi, Are you using the latest release version? Yes 1.7.2.471 Can you reproduce it? YES (if you cannot then we may struggle to also, making it even harder to fix) Does it happen for a new document? If not do you have a document you can share that shows the problem? NEW DOC If you cannot provide a sample document then please give an accurate description of the problem for example it should include most of the following: What is your operating system and version (Windows 10, OSX Mojave, iOS 12 etc)? WIN 10 What happened for you (and what you expected to happen) Provide a recipe for creating the problem (step-by-step what you did). OPEN NEW DOC AND PASTE AN IMAGE FROM THE STOCK Screenshots (very handy) or a screen capture/video. Any unusual hardware (like tablets or external monitors or drives that may affect things) or relevant other applications like font managers or display managers. NO TABLET Did this same thing used to work and if so have you changed anything recently? (software or hardware) Quote Link to comment Share on other sites More sharing options...
Staff Gabe Posted September 20, 2019 Staff Share Posted September 20, 2019 The curve does show up in the Curves panel. You have added one point on the master curve and moved it down slightly. Are you referring to the histogram in the Curves pop-up panel not showing up? Quote Link to comment Share on other sites More sharing options...
Vladimir78 Posted September 20, 2019 Author Share Posted September 20, 2019 @GabrielM, Sorry, yes i'm referring to the histogram in the Curves not showing up. Quote Link to comment Share on other sites More sharing options...
Staff Gabe Posted September 20, 2019 Staff Share Posted September 20, 2019 Is it slow to appear? If you wait a few seconds after you click the curves does it appear? How big is your image? Can you attach the project file? Quote Link to comment Share on other sites More sharing options...
A_B_C Posted September 20, 2019 Share Posted September 20, 2019 As Gabriel indicated: depending on the size of your image and the specs of your computer, it may take some time for Affinity Photo to calculate the histogram. I’ve seen that too. Quote Link to comment Share on other sites More sharing options...
Vladimir78 Posted September 20, 2019 Author Share Posted September 20, 2019 HI Many thanks for your answers. Here is the file of the project The histogram appeared on the whole pixel layer but when a part selected, the histogram does not appear.

A_B_C Posted September 20, 2019 Share Posted September 20, 2019 Wow, that’s pretty strange. It seems to work fine here. But I have to add, I am on a Mac. Maybe there’s a Windows bug that prevents the histogram from showing up. I am sorry that I am of little help in that case. Alex Quote Link to comment Share on other sites More sharing options...
Greyfox Posted September 21, 2019 Share Posted September 21, 2019 Seems to be working here also - Windows 10 Pro. Not nicely colored as with the Mac though.

Ray S. Posted September 21, 2019 Share Posted September 21, 2019 Hi, I'm on Win10 Home and the histogram doesn't show up in the Curves-adjustment. But if I check "Marquee" in the Histogram-Panel in the upper right corner, it shows the histogram of that selected part of the image. It also reacts to changes to the curve in almost realtime. Maybe this could be a workaround for this task. If I apply the curves-adjustment with no selection it shows the histogram immediatly.

Vladimir78 Posted September 21, 2019 Author Share Posted September 21, 2019 for a strange reason, now the histogram appears when clicking on the histogram panel ! Quote Link to comment Share on other sites More sharing options...
Greyfox Posted September 23, 2019 Share Posted September 23, 2019 @Vladimir78 To be honest, whilst the histogram in the Curves dialogue does show up here, I've not personally been able to see a lot of real value in it, and I tend to ignore it and use the main histogram for reference. For any of the selections Master/Red/Green/Blue the grey histogram in the curves dialogue appears to show the levels that exist pre any curves adjustment. (I'm not sure exactly how else to describe it). The histogram in the curves dialogue doesn't update live (or for that matter at all) with any changes actually made by the curves adjustments. I'm sure it wouldn't have been included just for decoration, so perhaps someone could enlighten me.

The histograms don't update for me, either, in any of the adjustments that include them. I think they're supposed to update. And they're not supposed to be gray.

I was surprised when I saw the screen shot of the colored ones in A_B_C's post above for the Mac system. I can't remember them ever being anything other than grey on Windows, and I can't remember them ever live updating either. I'd not been able to find any reference specifically about the curves adjustment histogram in the help file either, so just assumed it was how it was intended to be.

Staff Gabe Posted September 23, 2019 Staff Share Posted September 23, 2019 The histograms inside the Curves/Levels are not supposed to update when you change them, otherwise, they will show a wrong representation of what you're doing and will be useless. Take this for example: You would need the histogram to stay as is so you can adjust the black and white level to match the histogram. Otherwise, when you move the black slider to the right, the histogram will move to the left, and you will probably meet halfway in between, which is wrong. You have the main histogram updating so you should be using that as a reference. What I have logged with our developers is the gray histogram on Windows, which should be Colour to match the Mac build. walt.farrell 1 Quote Link to comment Share on other sites More sharing options...

Gabriel, Thanks for that. I completely understand the reasoning you have given in regards to the histogram in the Level adjustment dialogue, but I don't believe it is applicable to the histogram in the Curves dialogue. As it is at present, there is nothing I am aware of in the curves adjustment that is being referenced to its histogram. What is could show if it were live is whether the curves adjustment being applied is resulting in clipping at either end. It is of course possible to get that check by reference to the main histogram, which begs the point "what is the use then of having a non updating histogram in the curves dialogue at all?"

Staff Gabe Posted September 23, 2019 Staff Share Posted September 23, 2019 It's the exact way for Curves. If the histogram reacts, you will not get an accurate representation of the adjustment. Quote Link to comment Share on other sites More sharing options...
Greyfox Posted September 23, 2019 Share Posted September 23, 2019 @GabrielM Thanks again for your reply. Unfortunately I still don't see what use there is having a static histogram in the curves dialogue, but that is just me, and as the main histogram does provide the check I need when using the curves adjustment, I can live with it.
