Plot a alphabetic character in 2D

Question

I was wondering how I can graphically plot an alphabetic character, for example D, in 2 dimension, using mathematica? I was using ListPlot with specific x and y values but it's not looking anything like a D...

Help would be appriciated! :)

This is my current D:

I looked through the link right now, but that's not how I need to make it work. Thanks though:) — Vetenskap, Apr 14 '16 at 16:12

A bit unclear... do you want 2D coordinates for a given character or simply text in 2D... for the second, look (rather anticlimactically) at Text. — Yves Klett, Apr 14 '16 at 16:27
Obviously ListPlot can work only if you add more points. Maybe you want this? — Jens, Apr 14 '16 at 16:29

I just want to plot a D with points (x,y) values. I have five points right now, but maybe that's why I get this. — Vetenskap, Apr 14 '16 at 16:36
Yes, that's why you get this. But do you want a smooth curve, or just a way to calculate more points? It's not clear. — Jens, Apr 14 '16 at 17:12

How about discretizing the letter's boundary?

stringBoundary[char_String] := 
  RegionBoundary[DiscretizeGraphics[First@ImportString[ExportString[char, "PDF"]]]]

stringBoundary["D"]

This is also possible in v11.0+ with ImageMesh and Rasterize. The RasterSize ends up affecting mesh quality here:

RegionBoundary@ImageMesh@ColorNegate@Rasterize["любо",RasterSize->400]

You could also just get the edge by using a FillingTransform to ignore the interior of shapes:

RegionBoundary@ImageMesh@FillingTransform@ColorNegate@Rasterize["D", RasterSize -> 400]

To get the points on the D shape, just use MeshCoordinates. – flinty Sep 24 '20 at 14:17
