Crate femtovg

The femtovg API is (like NanoVG) loosely modeled on the HTML5 Canvas API.

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

Modules

• renderer
  Module containing renderer implementations.

Structs

• Atlas
• Canvas
  Main 2D drawing context.
• Color
  Struct for representing colors.
• CompositeOperationState
  Determines how a new (“source”) data is displayed against an existing (“destination”) data.
• DrawCommand
• FontId
  A font handle.
• FontMetrics
  Information about a font.
• GlyphDrawCommands
• ImageFlags
  Image flags (eg. repeat, flip, mipmaps, etc.)
• ImageId
  An image handle.
• ImageInfo
  Information about an image.
• Paint
  Struct controlling how graphical shapes are rendered.
• Path
  A collection of verbs (move_to(), line_to(), bezier_to(), etc.) describing one or more contours.
• PathIter
• Quad
• TextContext
  TextContext provides functionality for text processing in femtovg. You can add fonts using the Self::add_font_file(), Self::add_font_mem() and Self::add_font_dir() functions. For each registered font a FontId is returned.
• TextMetrics
  Result of a shaping run.

• Baseline
  Text baseline vertical alignment: Top, Middle, Alphabetic (default), Bottom.
• BlendFactor
  Blend factors.
• CompositeOperation
  Predefined composite oprations.
• ErrorKind
  Enum with all possible canvas errors that could occur.
• FillRule
  The fill rule used when filling paths: EvenOdd, NonZero (default).
• ImageFilter
  ImageFilter allows specifying the type of filter to apply to images with crate::Canvas::filter_image.
• ImageSource
  Image source
• LineCap
  Determines the shape used to draw the end points of lines: Butt (default), Round, Square.
• LineJoin
  Determines the shape used to join two line segments where they meet. Miter (default), Round, Bevel.
• PixelFormat
  Image format: Rgb8, Rgba8, Gray8.
• RenderMode
• Solidity
  Used to specify Solid/Hole when adding shapes to a path.
• Verb
