Lamont Posted November 2, 2015 Share Posted November 2, 2015 When saving a file in Export mode I am faced with resampling options. I have never before seen resampling options for saving a file, only when scaling a file. Can someone please elaborate?

JFisher Posted November 2, 2015 Share Posted November 2, 2015 Hi Lamont.There are a few different options for resampling, I have taken some information from the inbuilt help in the app and have found information that explains each resampling option. This should help :) Nearest Neighbour—simple resampling which has the fastest processing time. Use for hard-edge images. Bilinear—algorithmic resampling for use when shrinking images. Bicubic—algorithmic resampling for use when enlarging images. Resampling is smoother than Bilinear but has a slower processing time. Lanczos 3—complex algorithmic resampling which gives the best results but with the longest processing time. Available as 'separable' and 'non-separable'; the latter gives marginally better results, but is slightly slower than 'separable'.

Lamont Posted November 2, 2015 Author Share Posted November 2, 2015 Thanks for the reply. My question is not so much about the resampling options and differences between them. I only really use bicubic of the ones offered, because it is the only one that gives me results I like. Lancos 3 results for me always in terrible harshness. My question was really more about why I have to choose a resampling option when saving an image. In no other photo editing software see an option for resampling when saving an image. Why does saving require resampling if the image is not at the same time being scaled? Quote Link to comment Share on other sites More sharing options...

Staff MEB Posted November 8, 2015 Staff Share Posted November 8, 2015 Hi Lamont, The resample algorithm will only be used if you change the image dimensions. If you are simply exporting the image there's nothing to resample. Maybe we should grey out the Resample dropdown until the user changes one of the dimension fields. I will log this to be looked at. Thanks. [EDIT] Please check Ben's reply below. justwilliam 1 Quote A Guide to Learning Affinity Software Link to comment Share on other sites More sharing options...
anon1 Posted November 8, 2015 Share Posted November 8, 2015 I think he was confused by the fact that you have to choose one of the algorithms when exporting to jpg, png etc. Quote Link to comment Share on other sites More sharing options...
Staff Ben Posted November 9, 2015 Staff Share Posted November 9, 2015 Resampling is used when rasterising for export. If you have image elements in your document, they will use resampling to put them into export DPI. An Affinity document allows for image elements to be resized. Unlike Photoshop, resizing is non-destruction - the original image data is maintained, but it is resampled for displaying on screen, and resampled if you bake the image for export.

Staff MEB Posted November 9, 2015 Staff Share Posted November 9, 2015 Thanks Ben. Forgot the images resized inside the document! This also applies to some embedded documents in specific circumstances (different colour space than used on document i believe). My bad.

AffinityNewbie7 Posted December 29, 2018 Share Posted December 29, 2018 Hi, I have the same question for Affinity Photo. I have resized the document using bicubic resampling, now when I am exporting it is it getting resampled again (same bicubic)?? In simple terms, is the image getting resampled twice?

AffinityNewbie7 Posted December 30, 2018 Share Posted December 30, 2018 Is there a way to avoid this ''double resampling'' from happening? Quote Link to comment Share on other sites More sharing options...
