  1. Hi Guys, I have been trying to export png's of icons for a website. These are pretty small but there's a lot of them as they are used in CSS sprites. Normally I would export these as a gif or png8, but your settings only allow export to be dithered and that gives me some real quality issues. I'd love it if we could have an option not to dither the png8 and gif exports. I've attached the following files so you can see the problem: - site-product-icons11-OLD - The original png8 file out of Photoshop, undithered - I have just added 1 icon to the bottom of this file site-product-icons11a128 - 128 export (dithered) out of Affinity Photo - you can see the problem in spots of colour on say the LR logo 900px down and the steel logo at 450px down site-product-icons11a256 - as above but more colours to see if that was the issue site-product-icons11 - png24 export not showing these issues (no surprise really), but is almost 3x the file size. Thanks
  2. I am on Page 258 of the Affinity Photo Workbook and Paragraph 1 states Quote "Above the Background Dither Layer, create a new HSL adjustment by going to the Layer Menu and etc., etc. I do not see a 'Dither Layer' on the layers on this particular exercise and I do not know what Dither Layer is anyway. Can you help explain this Please. Thanks
  3. Hello Im a Photoshop CS5 user but want to do editing in 32bit so got Affinity Photo. I noticed than after exporting to png 24 I get colour banding, somthing I do not get when exporting the same file from Photoshop. Also note how the Photoshop png is producing a larger file so I assume there is some compression going on that Photohop is not doing? Thanks Dan
  4. Please add a choice of dither types when exporting GIF and PNG 8-bit images. As most web designers know, to get the best out of limited palettes you need to use the most appropriate dithering algorithm. Photo doesn't provide any choice, but it would be extremely useful to web designers who care about optimising their images for both file size and quality. If it can be implemented at the same time as a LIVE PREVIEW of the export settings then that would be mega cool. Thanks.
  5. FYI, this question has to do with AP: Looking at a recent image, I noticed some faint banding that was visible when I applied a color gradient (maybe it was there in the B&W version, but I couldn't see it). See the darker of these two images: https://forum.affinity.serif.com/index.php?/topic/20687-photos-from-a-mountaintop/(FWIW, I see the banding on my non-retina, late 2013 iMac; I haven't checked on other machines). Searching the forums I came across a comment about the "Dither Gradients" preference and the different effects if you are working in 8-bit or 16-bit (see MEB's comments in this thread: https://forum.affinity.serif.com/index.php?/topic/13742-unwanted-noise-in-gradients). So, my question: If I'm working in 16-bit, is it better to leave "Dither Gradients" preference checked? Or unchecked? Thanks, Darin
