Bill Henry Posted January 21, 2017 Share Posted January 21, 2017 Hi I have recently purchased Affinity Photo and I am enjoying it. I have a question. My wife is a stained glass artist and from time to time she has pictures that need to have the colour removed in order to create line art to use as patterns. What is the best way to remove the colour and leave an outline for the pattern? Quote Link to comment Share on other sites More sharing options...
manu schwendener Posted January 21, 2017 Share Posted January 21, 2017 Hello BillWelcome to Affinity Photo :-)This is what I tried: set the photo to black and white (in adjustments) and all the colour sliders to the right.Or: set the photo to black and white, then go to 'brightness / contrast' (also in adjustments) and set them to 100%.If anybody has another solution but no picture at hand: feel free to usehttp://manuschwendener.tumblr.com/post/26297108788, clicking brings you to a bigger size.

Bill Henry Posted January 22, 2017 Author Share Posted January 22, 2017 Thank you for your reply. That works for the most part but it still leaves some residue. I want to be able to create SVGs. I don't have Affinity Design so I don't know how well it does tracing. Quote Link to comment Share on other sites More sharing options...
Fixx Posted January 22, 2017 Share Posted January 22, 2017 If you need vector art you probably need a separate autotracing app. Quote Link to comment Share on other sites More sharing options...
Alfred Posted January 22, 2017 Share Posted January 22, 2017 Thank you for your reply. That works for the most part but it still leaves some residue. Even if you apply a threshold adjustment so that you only have black and white with no shades of grey in between, I don't think any raster effects or adjustments are going to give you clean lines without quite a bit of manual work. I want to be able to create SVGs. I don't have Affinity Design so I don't know how well it does tracing. Affinity Designer doesn't yet do auto-tracing at all.

Bill Henry Posted January 22, 2017 Author Share Posted January 22, 2017 Thanks all. I do have a separate app but I am trying to get the cleanest image before I take it over. If anyone has a better way I would sure like to know. Quote Link to comment Share on other sites More sharing options...
