Aug 11, 2022 · I am using openCV with python to extract contours from an image. Now I need to export these contour paths (list) as an svg paths. How can I achieve this ? code: ret,thresh = cv2.threshold(imgray...

Apr 12, 2022 · A fast python library and command line tool for generating contour maps from heightmaps and images. Given an image file (preferably RGB PNG), it will output a PNG with topographic contour lines and an SVG file of the contour lines.

linea is a prototype Python3 program for generating contour line SVG files suitable for laser cutting layers that stack to create an 3D topographic map.

Mar 6, 2018 · First, you need to compute the contours in your canny image using the findContorus function of OpenCV. Please be careful here, your contours MUST be well defined. Second, having your contours just follow this question: Convert contour paths to svg paths. The SVG paths can be opened in any image processing software (e.g. Inkscape, Photoshop, etc)

Sep 27, 2020 · The corners can be visualized nicely by converting each contour to an SVG polygon. You may refer to here for three choices to render the corners. I also add a function add_pixel_fillers to adjust close enough points.

This app find contours on images (using openCV) and generates SVG or G-code from them. I this created to be able to draw images using my Ender 3 Pro 3D printer, so basically converting it to a plotter.

May 20, 2023 · svgpathtools is a collection of tools for manipulating and analyzing SVG Path objects and Bézier curves. svgpathtools contains functions designed to easily read, write and display SVG files as well as a large selection of geometrically-oriented tools to transform and analyze path elements.

Dec 11, 2022 · I have been trying to find a way to convert my X, Y coordinates to spatial longitude and latitude and then draw the contour with another library like fiona. I have seen map projections using pyproj geopandas gdal but couldn't apply any of them to my case. Can you point me in …

IMHO, pstoedit (as suggested below) is great option (PS/EPS to DXF). If you don't use fonts conversion is very easy. If you can generate a postscript file (matplotlib can create pdf's right?) you might be able to use pstoedit from the command line to convert it to a dxf.
