This seems interesting to combine with ImageMagick but this time as a rasterizer tool and compare with other similar technologies. Although this technology was not designed for this (mostly to create art/animations/effects) I realized that it's also capable of trace an image.įinally I'm using svgo (svg optimizer in node.js and browser) which is capable of simplify any svg to a single or few paths. You can archieve almost perfect replicas, but the svg will have enourmous anount of shapes without any semantics and for most vector graphic use cases this is unuseful (imagine a plotting machine trying to cut/plot).Īlso I recently discovered "geometrize/primitive" technologies (, ) and made a port to JavaScript node.js browser API and CLI to easily test it. However if you want to "vectorize" photos the story is different. If you play a little bit, for logos/drawing it works nice (and if you only need monochrome output then potrace implementation is almost perfect). No so friendly playground (only potrace implementation).
I'm joining different tracer implementations I've found (so far only 2 in js) in this project: I was playing with image tracing technologies recently (JavaScript). When you ask IM to generate a SVG version of an image it does so by calling the AutoTrace library. This makes a good example of how good (or bad) the raster to SVG conversion is.
IMAGE CONVERTER TO SVG TRIAL
I even used it as trial method of image segmentation.Ĭompare the results of the scripts "segment_image" and "segment_via_svg" in the IM Examples Scripts area using the image However in some situations I have found a need to 'tweek' the 'angle' option to makeĪ sharp change instead of a curve for some images.Īs you can see I have experimented with Raster to SVG conversion using Autotrace. There are many rules and options for this which generally work well. Third it has to make decisions about weathe rto make a smooth curve or a sharp point when the direction of a shapes edge changes.If you ask for a circle you will NOT get a circle, but a rough polygonal representation of a circle, appropriate for the scale of the image being converted. Second it will only generate complex polygons of the shape.You are better off thresholding the image so as to brovide a clean edge for AutoTrace to trace other regionas and shapes of color. First it does NOT handle anti-aliased pixels very well.This is a bitmap to vector graphic converter, but it has some limitations. IM is a raster (pixel array) image processor, and as such when the IM draw command is used Which is compiled from source on my Ubuntu 9.04 machine. The resulted circles were always black and solid.ġ) Do I really have to write all my drawing commands in one draw argument (like the second example)?Ģ) Can I use graphics settings like stroke, strokewidth and fill to draw svg images? how?ģ) Can I use DIFFERENT colors for the same svg image? how?Ĭopyright: Copyright (C) 1999-2009 ImageMagick Studio LLC However, it didn't respect any of the attributes like fill and stroke. It worked correctly but it generated the last circle onlyĬonvert -size 100x100 -draw 'circle 20,20 10,10 circle 30,30 50,50' xc: test.svgĪnd it generated the two circles correctly. I'm using ImageMagick command line tool (convert) to generate svg images.įirst, I tried this command to generate an image with two circleĬonvert -size 100x100 -draw 'circle 20,20 10,10' -draw 'circle 30,30 50,50' xc: test.svg
