Inkscape Plugin For Engraving Fonts

[Windell] developed an Inkscape extension called Hershey Text that helps you process fonts into vector representations. If you’ve tried to 3D print, plot, or mill text in the past you may have run across the problem of generating vector paths that deal with the outline and fill of the text appropriately. The problem stems from how fonts are defined; either by the area that they enclose, or by the path that is used to draw the outline.¬†Check out [Windell’s]¬†tutorial for this extension where he explains each of these issues and shows how to overcome them.

The image above illustrates the stroke options, which allow you to vector multiple paths to best fill in the correct parts of each character using path-based hardware. The package includes a wide variety of interesting font sets that are in the public domain, and includes tools such as a glyph map generator that make it very user friendly.

How To Create TrueType From An Image


[Viacheslav] wanted his virtual terminal to have the look of a DEC VT220. He was unable to find a font set that looked just right so he set out to make his own TrueType font. He managed to find a sample image of the glyphs that the VT220 used as fonts. Using a collection of free software he sliced the image into 256 different parts, resized and converted to one-bit index images, and converted these to vector graphics. This was accomplished with a bit of python, an image tracing program, and font editor called FontForge.

Take some time to dabble with these font tools. With an adequate sample you should be able to reproduce any font set. We won’t achieve anything as sophisticated as the font printed with bacteria, but this will be a start in the right direction.

How To Generate Font And Picture Header Files


Displaying custom fonts or images on an LCD screen using a microcontroller usually requires quite a bit of work. We’ve used some readily available tools to make this a bit easier for your next project. Our python script will convert BMP files into a header file ready for use with AVR microcontrollers. We’ll walk you through it after the break. Continue reading “How To Generate Font And Picture Header Files”
