10.3 Fonts, characters, and languages

To reiterate, the AxiDraw is a single-function device designed to trace the vector

paths that you provide to it. The document that you prepare may include any

number and variety of different text and graphical elements, so long as they are

converted to paths before you plot them.

As its sole function is to follow paths, the AxiDraw itself does not use fonts (built-

in or otherwise) nor does it have knowledge about any written languages. Thus,

it has no preference for one language over another, and is equally happy to write

in English, Japanese, or Arabic,

so long as you can provide suitable input

. Similarly,

you can use fonts in any typeface style or character set– including foreign lan-

guages and including fonts that resemble handwriting.

Most fonts (e.g., truetype, opentype fonts) that are installed on your computer

are accessible directly from within Inkscape. You can create and edit

text objects in Inkscape by selecting the text tool, which you can select

by clicking the icon shown here, or by using F8 on your keyboard. You

can select between available fonts using the Text and Font panel, acces-

sible in the menu at

Text > Text and Font...

.

To convert your editable text into paths that can be plotted, select them and

choose from the menu

Path > Object to Path

. You may wish to save a separate

copy of your document before converting to paths, in case you wish to edit the

text again later.

This example was made using the font “Savoye LET” on a Mac.
