ICN (Icon System)

Description

ICN is a vector-based icon description language that's fundamental to originOS. It provides a simple and intuitive way to create vector graphics and dynamic icons. The ICN language supports both static and dynamic icons, with a straightforward syntax for drawing shapes, lines, and creating interactive elements.

Basic Concepts

Static vs Dynamic Icons

• Static Icons: Regular ICN files that describe fixed vector graphics

• Dynamic Icons: Icons marked with @dynamic that can respond to variables and conditions

Color and Style

• Colors are set using the c command with hexadecimal values

• Line weights are controlled using the w command

• Both affect all subsequent drawing operations until changed

Coordinate System

• Uses a standard coordinate system with (0,0) at the center

• Positive x extends right, negative x extends left

• Positive y extends up, negative y extends down

File Format

ICN files use a simple text format with one command per line. For dynamic icons, the first line must be @dynamic.

// Static icon example
c #fff
w 2
line 10 10 -10 -10

// Dynamic icon example
@dynamic
c #fff
$value > 50 (
    line 10 10 -10 -10
)

Integration

ICN files can be used in projects by utilizing the ICN3 Renderer, available at: https://github.com/Mistium/Origin-OS/blob/main/VersionsSource/Systems/ICN3%20Renderer.sb3
