Structs

• Canvas
  Canvas provides an interface for drawing, and how the drawing is clipped and transformed. Canvas contains a stack of Matrix and clip values.
• Color
• Decoration
• FontArguments
• FontStyle
• FramebufferInfo
• GlyphClusterInfo
• HSV
• IRect
• LineMetrics
• Matrix
• PlaceholderStyle
• Point
• PositionWithAffinity
• RGB
• RRect
• Rect
• TextBox
• TextDecoration
  Multiple decorations can be applied at once. Ex: Underline and overline is (0x1 | 0x2)
• TextShadow
• Weight
  Wrapper type of a font weight.
• Width
  Wrapper type for the width of a font.

Enums

• ArcSize
• BlurStyle
• ClipOp
• ColorType
• Corner
• EncodedImageFormat
• FilterMode
• Format
• GradientShaderColors
  Type that represents either a slice of Color, or a slice of [Color4f] and a color space. Whenever this type is expected, it’s either possible to directly pass a &[Color] , or a tuple of type (&[Color4f], &ColorSpace).

Functions

• raster_n32_premul
  Allocates raster Surface. crate::Canvas returned by Surface draws directly into pixels. Allocates and zeroes pixel memory. Pixel memory size is height times width times four. Pixel memory is deleted when Surface is deleted.
• set_resource_cache_single_allocation_byte_limit
• set_resource_cache_total_bytes_limit
• wrap_backend_render_target
  Wraps a GPU-backed buffer into Surface. Caller must ensure backend_render_target is valid for the lifetime of returned Surface.

Type Aliases

• BackendRenderTarget
• ColorSpace
• Data
• DirectContext
• FontCollection
• FontFeature
• FontMgr
• Image
  Image describes a two dimensional array of pixels to draw. The pixels may be decoded in a raster bitmap, encoded in a [Picture] or compressed data stream, or located in GPU memory as a GPU texture.
• Interface
• MaskFilter
  MaskFilter is the base class for object that perform transformations on the mask before drawing it. An example subclass is Blur.
• Paint
• Paragraph
• ParagraphBuilder
• ParagraphStyle
• Path
• RecordingContext
• RuntimeEffect
• Shader
• StrutStyle
• Surface
  Surface is responsible for managing the pixels that a canvas draws into. The pixels can be allocated either in CPU memory (a raster surface) or on the GPU (a RenderTarget surface). Surface takes care of allocating a Canvas that will draw into the surface. Call surface_get_canvas() to use that canvas (but don’t delete it, it is owned by the surface). Surface always has non-zero dimensions. If there is a request for a new surface, and either of the requested dimensions are zero, then None will be returned.
