The coordinate system’s origin is the top-left corner, with positive X rightwards, positive Y downwards.

Modules§
- Module containing renderer implementations.
Structs§
- Main 2D drawing context.
- Struct for representing colors.
- Determines how a new (“source”) data is displayed against an existing (“destination”) data.
- A font handle.
- Information about a font.
- Image flags (eg. repeat, flip, mipmaps, etc.)
- An image handle.
- Information about an image.
- Struct controlling how graphical shapes are rendered.
- A collection of verbs (
move_to()
,line_to()

, etc.) describing one or more contours. - TextContext provides functionality for text processing in femtovg. You can add fonts using the
Self::add_font_file()
,Self::add_font_mem()
andSelf::add_font_dir()
functions. For each registered font aFontId
is returned. - Result of a shaping run.
- 2×3 matrix (2 rows, 3 columns) used for 2D linear transformations. It can represent transformations such as translation, rotation, or scaling.
