## Classes

- [CachedTrimmedText](https://developer.rhino3d.com/api/gh2/type/grasshopper2.eto.drawing.cachedtrimmedtext.md): Caches a trimmed, left aligned piece of text.
- [Context](https://developer.rhino3d.com/api/gh2/type/grasshopper2.eto.drawing.context.md): Aggregates a bunch of information and functionality for drawing in graphics context. Primarily, a Context is better than a Graphics object as it provides information about the target object (either a bitmap or a control), and it allows for the animation of values and automatic invalidation of said target.
- [ExtendingPalette](https://developer.rhino3d.com/api/gh2/type/grasshopper2.eto.drawing.extendingpalette.md): A colour palette which auto-extends to more and more colours over time.
- [Motif](https://developer.rhino3d.com/api/gh2/type/grasshopper2.eto.drawing.motif.md): Describes a single hatch fill. It pays to re-use a Hatch instance as often as possible, since it caches hatch textures.
- [OpenColor](https://developer.rhino3d.com/api/gh2/type/grasshopper2.eto.drawing.opencolor.md): Provides access to the open-color standard: https://yeun.github.io/open-color/
- [OsColours](https://developer.rhino3d.com/api/gh2/type/grasshopper2.eto.drawing.oscolours.md)
- [OsFonts](https://developer.rhino3d.com/api/gh2/type/grasshopper2.eto.drawing.osfonts.md): The fonts the operating system uses for its own interface, for Grasshopper to draw with.
- [PinnedText](https://developer.rhino3d.com/api/gh2/type/grasshopper2.eto.drawing.pinnedtext.md): Creates a preplaced bit of text, either left, centre or right aligned within some frame.
- [StandardColours](https://developer.rhino3d.com/api/gh2/type/grasshopper2.eto.drawing.standardcolours.md): Provides access to the standard colours defined in the default Grasshopper colour dictionary.
- [StandardFonts](https://developer.rhino3d.com/api/gh2/type/grasshopper2.eto.drawing.standardfonts.md): Provides access to the default fonts used in Grasshopper.
- [TextBalloonF](https://developer.rhino3d.com/api/gh2/type/grasshopper2.eto.drawing.textballoonf.md): A [BalloonF](https://developer.rhino3d.com/api/gh2/type/grasshopper2.eto.drawing.balloonf.md) shape surrounding some lines of text.
- [WireframeF](https://developer.rhino3d.com/api/gh2/type/grasshopper2.eto.drawing.wireframef.md): A collection of wireframe shapes.
