Colors and fonts

Simulation Instrument Studio 1

An instrument draws in its own pixel size. The panel scales the finished picture. Colors and type are chosen in that instrument space.

Colors

Draw calls take a hex color. Text can take the same color in its style string.

_fill("#14181e")
_stroke("#e23b3b", 3)
_txt("120", "size:14; color:#e8eaee; halign:center;", x, y)

The altimeter sample uses the older style string on txt_add:

txt_add("----", "-fx-font-size:18pt; -fx-fill:#f2f2f2; -fx-font-weight:bold;", 140, 248, 120, 28)

Name the family in the style string. The font has to be installed on the computer running Studio or Panel.

_txt("ALT", "font:Roboto; size:14; color:#e8eaee;", x, y)

Free fonts to start with:

Google Fonts — Roboto, Inter, and the rest of the catalog. Download the family and install it.
DaFont — display and instrument-style faces. Check the license on the font before you ship an instrument.

A face you use in a community instrument should be one you can redistribute, or one you tell the downloader to install.
