31-May-2020 Update to version 1.01
Changes : now exporting the polygons to more lines, it used to be just 1 line, OpenSCad can handle that but the editor gets very slow. Now the polygon is split into multiple lines and the editor stays speedy.
The disadvantage however is that instead of deleting one line and replacing it to test different polygons you now need to select a number (sometimes a big number) of lines.
23-may-2020 Update to version 1.0
New options : treshold lower and upper limit (band select)
Anchor 'from image' meaning different polygon scans from the same
image will be at the correct position.
Also made a new demo video
Image to polygon converter for openscad, takes an image preferably black and white but tresholding can be done in the program and makes an openscad contour on the clipboard that can be pasted into openscad
Can export to SVG which can be used for laser cutting.
Bug Fix (jun 28 2019):
turned out that values were written with comma's when using the boundary, fixed to
dots and works now. (depended on local settings and i switched to a new computer
so i noticed it. . .).
Update 5 april 2019 :
Export to SVG now produces a normal InkScape document, can be used for laser cutting etc.
Update 29-Aug-2016 :
Can choose anchor point, can export outline.
Added Source
Update 30-dec-2014 : now also blob visualisation (see extra image)
Trace black and white bitmap images to openscad polygons.
The result ends up on the clipboard so you can paste it into openscad.
Be aware that the polygon is 2 dimensional, you have to do a linear_extrude to get it 3D. . .
