g_lab Posted June 19, 2020 Share Posted June 19, 2020 Hi, I want to place tiff images containing Alpha channels and choose if they should appear cut out or if the Alpha channel is ignored. How can I do that? Quote Link to comment Share on other sites More sharing options...
Wosven Posted June 19, 2020 Share Posted June 19, 2020 Hi, Sadly, there's no way to save a TIFF with multi pathes and multi alpha channels as we are use to do with PS, to select later the ones we want to use depending of the situation. You can save a TIFF with different pathes and masks hidden, but you'll need later to open and modify the file depending of your need, since you can't access them in APub, for example, if the file is linked. If it's for using in ID or QXP, that'll be the same. You'll have to open the file, active a mask, or use a path to clip the image, and save it again before importing or updating the file.

g_lab Posted June 19, 2020 Author Share Posted June 19, 2020 If I understand you correctly, there is no way to choose to use the alpha channel as a clipping mask or not. That's a pity because I like to render images with alpha channel and decide later if I want to use them, or not. This should definitely be a feature in a future update.

Old Bruce Posted June 19, 2020 Share Posted June 19, 2020 You can save Spare Channels and then load them into the Alpha channel. Quote Mac Pro (Late 2013) Mac OS 12.7.2 Affinity Designer 2.3.1 | Affinity Photo 2.3.1 | Affinity Publisher 2.3.1 | Beta versions as they appear. I have never mastered color management, period, so I cannot help with that. Link to comment Share on other sites More sharing options...
g_lab Posted June 22, 2020 Author Share Posted June 22, 2020 Thanks! I'm getting closer to the functionality I need, but not completely. In Affinity Photo I saved two Spare Channels: A white one (no mask) and the mask for to cut out the object if needed in a different task. (It seems Publisher cannot do that) So I can decide in Photo which one to load into Alpha. As the .afphoto file is linked in Publisher, this way I can decide whether to use the mask, or not. However, using this technique I still have to save a new file (.afphoto) and cannot use the original tif file which contains the only one alpha mask channel. So still it would be better to have the option to use the alpha mask of the original tiff image as clipping mask or ignore it. I'll suggest that in the wishlist.
