work some basic tutorials or get a friend to help.beg, steal or borrow a copy of Adobe Illustrator (sorry for an ancient version but it still works and does not want regular payments).
You may need to tweak some of the previous settings if you want things like the type to come out clearly. You should have a nice line art image to use. Once you are happy with what you are seeing on screen, choose Object > Image Trace > Expand This is always a play around and see what happens part for me. You may want to play with the Advanced sliders a bit too, to get yourself a better result. Twirl down the advanced options and make sure that the Stokes toggle is picked and the fills is not. Open the the Image trace Panel (Window > Image Trace).Ĭhoose Line Art from the Presets drop down.Īdjust the Threshold to something pretty high (I used 249. With the graphic selected, choose Image Trace > Make from the Object menu. (Alternatively you can create a new document and drag or place the png/jpg in) Open your png or jpg file in Illustrator. Hopefully this will help you out! These are the steps I took to create a line only (no fills) version of your graphic. Not averse to spending a few pounds on different software, but ideally do not want to shell out for a full copy of illustrator! I have Inkscape, Omnigraffle, and various apps. I've attached an example of the image I'm trying to recreate. If I try and 'trace' using the bezier tool on the omnigraffle app or program, it produces something nothing like the image I'm tracing, and is impossible to tweak (I have multiple images) If I try and 'trace' using the freehand tool on the omnigraffle app, it produces raster lines - not what I want
If I use a 'convert to paths' tool, it invariable creates shapes rather than lines, to account for what it perceives as different thicknesses.
I have spent some money on various apps, and have Inkscape, but I am struggling. This can be achieved if I can get them into pdf format - omnigraffle will happily read that. What I need (ideally!) is to get them into omnigraffle, as vectors. I have a program that outputs isobars - lines of equal pressure. I have googled extensively on this, and am running around in circles.
