Lojza Posted October 28, 2015 Share Posted October 28, 2015 Hi, I'd like to ask for two enhancements of Perspective Tool: 1) Now, when using Perspective Tool on an image, the image gets rasterized first and then the perspective adjustments can be applied. This has a nasty side effect: rasterized images are cropped according to current canvas. If the original placed image is bigger than the canvas, it gets cropped no matter that the result perspective transformation would fit on the canvas. So it would be much more usable, if the image won't get cropped and the Perspective Tool would work "outside" the canvas. 2) I'm not sure about what resampling algorithm Perspective Tool uses, but it produces unsatisfactory results by now. See attached screenshots. First is an original iPhone screenshot, which I'd like to place into a mockup. The second is the result after Perspective adjustment. The result is not "smooth", but rather too sharp, no antialiasing used... Straight solid lines are not transformed into "light grey antialiased lines" (or how to name it), but rather into sharp black dashed lines... It seems like "nearest neighbor" is used for the Perspective transform. Would it be possible to use either bicubic or bilinear algorithms for these transforms? This also applies to Mesh Warp Tool. Thanks for considering! WilliamNok and AltisKa 2 Quote UX/UI designer, IT analyst & consultant, Business Architect at Cool Ticket (www.coolticket.co).

Staff MEB Posted October 28, 2015 Staff Share Posted October 28, 2015 Hi lojza, Can you check if you have the View Quality set to Bilinear (Best Quality) in Affinity Photo ▸ Preferences, Performance tab?

Lojza Posted October 29, 2015 Author Share Posted October 29, 2015 Hi Meb, No, I use "Nearest neighbour" for view quality. Yet changing this to Bilinear has no effect on Perspective tool outputs. Resulting perspective adjustment is still "nearest-neighbourish". (To be honest, I second this behavior. If view quality setting would affect tools behaviour, that would be very confusing to me... It would be like if View mode in Designer (retina, pixel, vector...) would affect document resolution or something...)

Noob Posted October 29, 2015 Share Posted October 29, 2015 Agree with @Lojza. Also is there a way to prevent rasterizing when use the perspective filter? Quote Link to comment Share on other sites More sharing options...
Staff MEB Posted October 29, 2015 Staff Share Posted October 29, 2015 Can you please attach your file here so i can check it out? It shouldn't look that bad... Thanks.

Lojza Posted October 30, 2015 Author Share Posted October 30, 2015 Hi Meb, here is the attachment. I've also included the original image...

Lojza Posted October 30, 2015 Author Share Posted October 30, 2015 Just for the record, I'd expect Perspective tool to produce similar result like on this image: http://s25.postimg.org/9sch90u0f/screenshot_0011.png Quote UX/UI designer, IT analyst & consultant, Business Architect at Cool Ticket (www.coolticket.co).

Staff MEB Posted October 30, 2015 Staff Share Posted October 30, 2015 Thanks for the file. The problem is not with the perspective but with the rescaling while doing so. To avoid this, rescale the screen first to near the phone dimensions, then apply the Perspective Tool.

00Ghz Posted October 30, 2015 Share Posted October 30, 2015 Thanks for the file. The problem is not with the perspective but with the rescaling while doing so. To avoid this, rescale the screen first to near the phone dimensions, then apply the Perspective Tool. I got in the past a similar issue. Maybe the perspective tool should work in a smarter way to account for the different DPI results?

Lojza Posted October 31, 2015 Author Share Posted October 31, 2015 00GHz, I agree... The workarounds are always... just workarounds. Anyway, thank you Meb. Now I'm able to get to the results I need. anon1 and 00Ghz 2 Quote UX/UI designer, IT analyst & consultant, Business Architect at Cool Ticket (www.coolticket.co).
