iconoclast Posted June 3, 2021 Share Posted June 3, 2021 Is the background of the document you insert the image set to transparent? If not, it will be opaque and can't display transparency. You can change to transparent background in the menu Document by clicking on Transparent Background. Quote Link to comment Share on other sites More sharing options...
深红命运 Posted June 3, 2021 Author Share Posted June 3, 2021 No. I have set transparent background in the menu Document. If I paste copy layer image from Affinity Photo to other app(pureref)，it keeps transparent. But if i copy and paste the same image to Affinity Photo，it will be back.

iconoclast Posted June 3, 2021 Share Posted June 3, 2021 I have no experiences with pureref, but I copied from GIMP to Photo some minutes ago, and it worked without problems. What kind of software is pureref? I suggest the problem might be caused more on that side. Does it work with other programs (for example from pureref to GIMP, Krita, paint.net or so)?

It is interesting.I do not know how it works in clipboard to change Alpha Channel image in windows. There are many image formats in windows ? I mainly use ArtRage for painting. It has its own freely positionable and rotatable reference panels that are always on top, except you drag the brush across it - so that it doesn't disturb when you paint. So I never used something like pureref (even it sounds interesting) and can't say much about stuff like that and if it is even intended to copy images from it to other programs. That it doesn't work with Photo could possibly have to do with colour profiles, but I'm not sure about that. How is the transparency displayed in pureref? Also as checkerboard? Edit: By the way, also to copy and paste an image with transparencies from ArtRage to Photo works fine. I unfortunatly don't have much more programs to test it out.

Can you show a screenshot of your document + layers + tools panels and with the Move Tool selected? If the layers panel contains collapsed layers please unfold them for the screenshot. Create the copy of the desired layer and select the original layer (below the copy) for the screenshot.

深红命运 Posted June 7, 2021 Author Share Posted June 7, 2021 The first one is the screenshot i copy layer from photo to pureref. The seconed one is the screenshot i copy layer from pureref to photo . The alpha will be black! The last one is the screenshot i copy layer from pureref to ClipStudioPaint. It works fine. Quote Link to comment Share on other sites More sharing options...
iconoclast Posted June 7, 2021 Share Posted June 7, 2021 On the second Screenshot (pureref to Poto), there are two visible layers with your drawing in the layers panel. The preview images on those layers both seem to have a black background. But the image seems to show parts of the drawing with a transparent background in the corner on the left bottom of the image. What does it look like if you make the top layer invisible? Edit: One idea: Have you tried another file format? For example PNG or TIFF (both support transparencies)? PSD is the native format of Photoshop files, and as far as I remember Photo doesn't support all features of PSD. But I may be wrong. Quote Link to comment Share on other sites More sharing options...
thomaso Posted June 7, 2021 Share Posted June 7, 2021 > What does it look like if you make the top layer invisible? @ iconoclast, what would you possibly expect to appear differently than in the screenshot above this? Also it seems the two thumbnails aren't identical, only the background in the (unnamed) copy looks black, while in the layer below (name 1) it looks rather dark gray in both screenshots. Both blend modes seem to be "正常" = "normal". <> Quote macOS 10.14.6 | MacBookPro Retina 15" | Eizo 27" | Affinity V1 Link to comment Share on other sites More sharing options...
iconoclast Posted June 7, 2021 Share Posted June 7, 2021 Sorry, I really have no more ideas about the reason for this behaviour. Quote Link to comment Share on other sites More sharing options...
thomaso Posted June 7, 2021 Share Posted June 7, 2021 It seems to be influenced by the way the content gets written to the clipboard memory. However, there are various threads (for instance these) about alpha/transparency appearing black in Affinity or in prints from Affinity, often with rasterized image formats like PNG, but also with container formats as e.g. PDF or SVG. – Maybe this info can give a hint: 深红命运 1 Quote macOS 10.14.6 | MacBookPro Retina 15" | Eizo 27" | Affinity V1 Link to comment Share on other sites More sharing options...
深红命运 Posted June 8, 2021 Author Share Posted June 8, 2021 I have seem the topic.So，It is bug？I hope staffs fix it in new version. Quote Link to comment Share on other sites More sharing options...
thomaso Posted June 8, 2021 Share Posted June 8, 2021 I am not sure if your specific issue (pureref) is on the bugs list already. If you did not find it in the search results you also could write a new topic in the bugs forum. There you can post a link to this topic, too. And possibly upload a sample Affinity document to the forum for further investigation of your copy/paste issue with black alpha.
