![]() Make sure you select “OpenSCAD DXF Output (*.DXF)” as the file type to save as. Now, we can save it to DWF using the extension we installed earlier. Move the vector path out of the way by dragging and dropping it. One is a vector path of the leaf veins, overlaid on top of the bitmap of the leaf veins. I just used the default options, but you can play around with things then click update to see what it would look like. First select the bitmap by clicking on it. ![]() Next, we want to trace the bitmap we have as a path. Once you have that installed, open up Inkscape and load up the leaf PNG we just saved. When it asks you if you want to link or embed, choose embed. (If you’re all-pro, you can use git to clone the extension into the inkscape extension folder.) Windows: C:\Program Files\Inkscape\share\extensions\.Mac OS X: /Applications/Inkscape.app/Contents/Resources/extensions/.Where the extensions folder is located depends on what system you’re using. To install it in Inkscape, copy the *.py and *.inx files (in the zip file of the extension) to your Inkscape extensions folder. It can’t read all types of DXF files, so we need to install an Inkscape extension that allows us to save DXF files in a format OpenSCAD can read. This is where OpenSCAD gets a little finicky. Now, we’ll use an open source tool for vector drawings, called Inkscape, to convert the PNG to DXF. Now that our image is edge detected, and we can now save it to a file as a PNG. ![]() Lastly, we want to crop the image to make the details more visible, as well as reducing the complexity of the image, so the PNG to DXF conversion won’t take a long time. Adjust it until it the veins are thick, but there aren’t too many spots in the cells between the veins. Now, we want to make the veins a solid black and white. Move switch the positions of the black and white arrows in “Output Levels” After you open up GIMP, then open up the leaf vein picture above through File -> Open. Next, I fired up GIMP, an open source alternative to Photoshop. There were a good number of results, but I picked this one by Steve Jurvetson, which fulfilled my criteria above. I used flickr’s advanced search, so you can look for CC images. I also needed the image to be sharp (damn you, tilt-shift) with high contrast. I need something that was CC-BY, which allowed derivative works. That’s what the rest of this tutorial will help you do, and what I learned.įirst, I had to go find a creative commons image of some leaf veins. However, instead of drawing a leaf pattern myself, I generated the pattern from an image using free tools. To do something a bit more organic, my concept was to have a pattern of leaf veins for my iPhone backcover, Graftleaf. ![]() Yes, there’s too many 3D printable models of iPhone covers, but sometimes, we reinvent wheels not to have more wheels, but to have more inventors. Lets include the baselayer and a geojson we want in the shot in the "snapshot-pane", and a path we dont want in the shot in the "dont-include" pane: // Add baselayer and geojson to snapshot paneĬonst greekborder = L.Recently, to do a little bit of 3D modeling, I wanted to try my hand at making a modular back cover for my iPhone. Now we can create our layers within those panes, whether they're tile layers or geojson or paths or whatever. ![]() Var map = L.map("leafletMapid", mapOptions) Really all you're going to need is what layers you dont want in the screenshot, but we'll create two for good measure: //Create a map and assign it to the map div Here's a walkthrough of what I did: Custom panesįirst, lets create some custom panes to separate out what we want in the shot from what we dont. This can be done with the help of leaflet-simple-map-screenshoter, and some careful image manipulation. ![]()
