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

CubicResampler

Specify b and c (each between 0…1) to create a shader that applies the corresponding cubic reconstruction filter to the image.

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).

Traits

PointerWrapper

This trait supports the conversion of a wrapper into it’s wrapped C/C++ pointer and back.

Functions

blur

Create a filter that blurs its input by the separate X and Y sigmas. The provided tile mode is used when the blur kernel goes outside the input image.

raster_from_data

Creates CPU-backed Image from pixel data described by info. The pixels data will not be copied.

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.

render_target

Returns Surface on GPU indicated by context. Allocates memory for pixels, based on the width, height, and crate::ColorType in ImageInfo. budgeted selects whether allocation for pixels is tracked by context. image_info describes the pixel format in crate::ColorType, and transparency in crate::AlphaType, and color matching in crate::ColorSpace.

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

Bitmap

Bitmap describes a two-dimensional raster pixel array. Bitmap is built on ImageInfo, containing integer width and height, ColorType and AlphaType describing the pixel format, and ColorSpace describing the range of colors. Bitmap points to [PixelRef], which describes the physical array of pixels. ImageInfo bounds may be located anywhere fully inside [PixelRef] bounds.

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.

ImageFilter

Interface

MaskFilter

MaskFilter is the base class for object that perform transformations on the mask before drawing it. An example subclass is Blur.

Path

Path contain geometry. Path may be empty, or contain one or more verbs that outline a figure. Path always starts with a move verb to a Cartesian coordinate, and may be followed by additional verbs that add lines or curves. Adding a close verb makes the geometry into a continuous loop, a closed contour. Path may contain any number of contours, each beginning with a move verb.

SkSurface

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.
