Martin Brooks Posted February 23, 2018 Share Posted February 23, 2018 Hello Affinity designers, I have a lot of fun using AD to explore automatically vectorized images. Here is a gallery: www.shapevision.gallery Right-click on the shape images to download, and then check them out in AD. These svg images were produced by a new method. Although it is targeted at engineering applications, perhaps there is application for creators. Ideas?!? You can get a sense of how the method works by trying it here: www.shapevision.technology .

Lon in MacArkansas Posted February 25, 2018 Share Posted February 25, 2018 Very interesting effects, Martin. Welcome, and thanks for the link. Quote Link to comment Share on other sites More sharing options...
VectorVonDoom Posted February 25, 2018 Share Posted February 25, 2018 I don't understand but it's Sunday and my brain is asleep. Are they complex as they're not combining areas of the same colours but creating them as individual pixels, so lots of squares? In which case why would you want that? Some look fine but they're not what I was expecting. Quote Marc ArtByMarc.me Link to comment Share on other sites More sharing options...
Martin Brooks Posted February 25, 2018 Author Share Posted February 25, 2018 Hello Lon and VectorVonDoom, and all Affinity members. Thank you for looking at the shape images. I am hoping to engage artists and designers who can use shape images in their workflow; please contact me if you are interested. vonDoom, your comment identifies the presence of pixel-size square shapes in some images; here is an explanation; I hope this is helpful: The method does not combine areas of same colour; in fact, the method works with the greyscale image, determining colours after the shapes have been determined. The main task is to determine polygons (i.e. shapes) having boundaries each of which has constant lightness (i.e. constant gray value). These polygons may be highly irregular in shape; their coordinates are expressed to sub pixel accuracy (1/10th of a pixel for the images in the Gallery). It is these polygons that are the "shapes" in ShapeVision. But as you noticed, some images do have clusters of pixel-sized squares all filled with the same colour; here's why: For some of the constant-boundary polygons (i.e. polygons having boundary of constant lightness), the boundary is not a line, but instead has nonzero area (of constant lightness) -- it is these nonzero-area boundary regions that are filled with pixel-size squares. This fill-by-pixel-size-squares occurs only in some images, as needed, but this is not the dominant mode of operation for ShapeVision.

Lon in MacArkansas Posted February 25, 2018 Share Posted February 25, 2018 Some of them were very interesting...especially the flowers and colored pots. Much of it reminded me of the Auto-Trace feature in DrawPlus, although I think the results here are even better. Quote Link to comment Share on other sites More sharing options...
gdenby Posted February 25, 2018 Share Posted February 25, 2018 Hi, Martin, There have been many request made to add in a tracing function for Affinity. Because there is not one, I have used various tracing apps. Yours seems to be as good or better than those I've tried. I played w. the rasberry canes file using AD. The file opened and could be altered w/o incident. I spent some time at the web site trying various options. There were more than I could spend time trying to use. For my creative creative purposes, none were quite realistic enough to translate an image. Some of the sample images when drawn in the coarse setting range did give good results turning the image into a more schematic representation. As you mention, the process was developed for engineering. I would probably use the coarse methods to start simple line drawings that held close to the base image. Can you offer some images translated for engineering use? From what I've seen on this forum, there are users who make schematic, not creative, images. Perhaps show some transforms of geometric shapes.

Martin Brooks Posted February 25, 2018 Author Share Posted February 25, 2018 Thank you gdenby, I would be happy to try to identify an appropriate coarseness that would suit your style of work. Look for a post from me in a day or two. If you would like to suggest some sample images, that would be great. The engineering images that I have are medical, with a concentration in ophthalmology; their image parse may or may not be useful for you. Or cat and dog images ... Thanks for your interest!

Martin Brooks Posted February 28, 2018 Author Share Posted February 28, 2018 Hello again gdenby and all, As promised, here are some images with coarser settings. Press the green buttons to see each. Please let me know if these satisfy your curiosity, or whether there are other tests that I can do for you that might be useful. For example, please suggest some images for me to try. By the way, I notice that when downloading shape images by right-click, some browsers sometimes attach the wrong file extension. The extension should be .svg, but I have seen both .svgz and .svg.css -- in these cases you can rename the file to .svg either in the browser dialog or after download. I.e. the file is actually an svg file.
