Pixelly font library for OpenSCAD

cults3d

This is a user-created OpenSCAD library to generate pixelly fonts based on PalmOS bitmap fonts from Ron Buelow. The library includes 29 fonts. I used it to make a Minecraft-themed cake topper for a birthday celebration. You can find the full library code here - this Thing only includes a self-contained demo file. To use, begin with: include <pixellyfont.scad> The syntax for the main library call is as follows: renderString(string, font=font_8x8, halign="left", valign="bottom", invert=false, spacing=1, size=10, pixelScale=1.01, height=0) string: text to be rendered; only characters in the CP-1252 character set are supported; other characters will be turned into spaces font: font to use; fonts are defined in fontdata.scad halign: horizontal alignment: "left", "right" or "center" valign: vertical alignment: "bottom", "top" or "center" invert: set to true if you want to draw the background instead of characters spacing: scale for character spacings size: height of characters pixelScale: scaling to apply to pixels; increasing it noticeably above 1 makes pixels join up, and decreasing it below 1 results in blank space around them height: height to extrude pixels; set to 0 to make pixels 2D You can also use renderString() as a modifier for a shape. In this case, pixelScale and height are ignored, and instead the shape is used as a pixel. For instance, you can do this to make foreground pixels be large circles and background pixels be small circles: renderString("abc") circle(d=1); renderString("abc", invert=true) circle(d=0.1); If you want to know how much horizontal space text will take up, you can call getStringWidth(string[, options]) where the available options are the font, spacing, and size options that renderString() uses. If you want to know how many pixels high characters in a font are, call getFontHeight(font). You can then compute the size of an individual pixel as size/getFontHeight(font) where size is the size parameter for renderString().
