pub fn to_a_color_matrix(&self) -> Option<[scalar; 20]>

If the filter can be represented by a 5x4 matrix, this returns the matrix appropriately. If not, this returns None and ignores the parameter.

pub fn is_alpha_unchanged(&self) -> bool

Returns true if the filter is guaranteed to never change the alpha of a color it filters.

pub fn filter_color(&self, color: impl Into<Color>) -> Color

👎Deprecated since 0.79.0: Use filter_color4f()

pub fn filter_color4f( &self, color: impl Into<Color4f>, src_color_space: Option<&ColorSpace>, dst_color_space: Option<&ColorSpace>, ) -> Color4f

Converts the src color (in src colorspace), into the dst colorspace, then applies this filter to it, returning the filtered color in the dst colorspace.

pub fn composed(&self, inner: impl Into<ColorFilter>) -> Option<Self>

Construct a color filter whose effect is to first apply the inner filter and then apply this filter, applied to the output of the inner filter.

result = this(inner(…))

pub fn with_working_color_space( &self, color_space: impl Into<ColorSpace>, ) -> Option<Self>

Return a color filter that will compute this filter in a specific color space. By default all filters operate in the destination (surface) color space. This allows filters like Blend and Matrix, or runtime color filters to perform their math in a known space.

pub fn alpha_type(&self) -> AlphaType

Returns AlphaType.

AlphaType returned was a parameter to an Image constructor, or was parsed from encoded data.

Returns: AlphaType in Image

pub fn color_type(&self) -> ColorType

Returns ColorType if known; otherwise, returns ColorType::Unknown.

Returns: ColorType of Image

example: https://fiddle.skia.org/c/@Image_colorType

pub fn color_space(&self) -> ColorSpace

Returns a smart pointer to ColorSpace, the range of colors, associated with Image. The smart pointer tracks the number of objects sharing this ColorSpace reference so the memory is released when the owners destruct.

The returned ColorSpace is immutable.

ColorSpace returned was passed to an Image constructor, or was parsed from encoded data. ColorSpace returned may be ignored when Image is drawn, depending on the capabilities of the crate::Surface receiving the drawing.

Returns: ColorSpace in Image, or None, wrapped in a smart pointer

example: https://fiddle.skia.org/c/@Image_refColorSpace

pub fn is_alpha_only(&self) -> bool

Returns true if Image pixels represent transparency only. If true, each pixel is packed in 8 bits as defined by ColorType::Alpha8.

Returns: true if pixels represent a transparency mask

pub fn to_shader<'a>( &self, tile_modes: impl Into<Option<(TileMode, TileMode)>>, sampling: impl Into<SamplingOptions>, local_matrix: impl Into<Option<&'a Matrix>>, ) -> Option<Shader>

Make a shader with the specified tiling and mipmap sampling.

pub fn to_raw_shader<'a>( &self, tile_modes: impl Into<Option<(TileMode, TileMode)>>, sampling: impl Into<SamplingOptions>, local_matrix: impl Into<Option<&'a Matrix>>, ) -> Option<Shader>

to_raw_shader functions like to_shader, but for images that contain non-color data. This includes images encoding things like normals, material properties (eg, roughness), heightmaps, or any other purely mathematical data that happens to be stored in an image. These types of images are useful with some programmable shaders (see: crate::RuntimeEffect).

Raw image shaders work like regular image shaders (including filtering and tiling), with a few major differences:

• No color space transformation is ever applied (the color space of the image is ignored).
• Images with an alpha type of Unpremul are not automatically premultiplied.
• Bicubic filtering is not supported. If SamplingOptions::use_cubic is true, these factories will return None.

pub fn peek_pixels(&self) -> Option<Pixmap<'_>>

Copies Image pixel address, row bytes, and ImageInfo to pixmap, if address is available, and returns true. If pixel address is not available, return false and leave pixmap unchanged.

• pixmap storage for pixel state if pixels are readable; otherwise, ignored

Returns: true if Image has direct access to pixels

example: https://fiddle.skia.org/c/@Image_peekPixels

pub fn is_texture_backed(&self) -> bool

Returns true if the contents of Image was created on or uploaded to GPU memory, and is available as a GPU texture.

Returns: true if Image is a GPU texture

example: https://fiddle.skia.org/c/@Image_isTextureBacked

pub fn texture_size(&self) -> usize

Returns an approximation of the amount of texture memory used by the image. Returns zero if the image is not texture backed or if the texture has an external format.

pub fn is_valid(&self, context: &mut RecordingContext) -> bool

Returns true if Image can be drawn on either raster surface or GPU surface. If context is None, tests if Image draws on raster surface; otherwise, tests if Image draws on GPU surface associated with context.

Image backed by GPU texture may become invalid if associated context is invalid. lazy image may be invalid and may not draw to raster surface or GPU surface or both.

• context GPU context

Returns: true if Image can be drawn

example: https://fiddle.skia.org/c/@Image_isValid

pub fn make_scaled( &self, info: &ImageInfo, scaling: impl Into<SamplingOptions>, ) -> Option<Image>

Create a new image by copying this image and scaling to fit the ImageInfo’s dimensions and converting the pixels into the ImageInfo’s crate::ColorInfo.

This is done retaining the domain (backend) of the image (e.g. gpu, raster).

Returns None if the requested crate::ColorInfo is not supported, its dimensions are out of range.

pub fn flush<'a>( &self, context: &mut DirectContext, flush_info: impl Into<Option<&'a FlushInfo>>, ) -> SemaphoresSubmitted

👎Deprecated since 0.63.0: use gpu::DirectContext::flush()

See Self::flush_with_info()

pub fn flush_with_info( &self, context: &mut DirectContext, flush_info: &FlushInfo, ) -> SemaphoresSubmitted

👎Deprecated since 0.46.0: use gpu::DirectContext::flush()

Flushes any pending uses of texture-backed images in the GPU backend. If the image is not texture-backed (including promise texture images) or if the gpu::DirectContext does not have the same context ID as the context backing the image then this is a no-op.

If the image was not used in any non-culled draws in the current queue of work for the passed gpu::DirectContext then this is a no-op unless the gpu::FlushInfo contains semaphores or a finish proc. Those are respected even when the image has not been used.

• context the context on which to flush pending usages of the image.
• info flush options

pub fn flush_and_submit(&self, context: &mut DirectContext)

👎Deprecated since 0.63.0: use gpu::DirectContext::flush_and_submit()

Version of flush() that uses a default gpu::FlushInfo. Also submits the flushed work to the GPU.

pub fn backend_texture( &self, flush_pending_gr_context_io: bool, ) -> Option<(BackendTexture, SurfaceOrigin)>

👎Deprecated since 0.63.0: use gpu::images::get_backend_texture_from_image()

Retrieves the back-end texture. If Image has no back-end texture, Noneis returned.

If flush_pending_gr_context_io is true, completes deferred I/O operations.

If origin in not None, copies location of content drawn into Image.

• flush_pending_gr_context_io flag to flush outstanding requests

Returns: back-end API texture handle; invalid on failure

pub fn read_pixels_with_context<'a, P>( &self, context: impl Into<Option<&'a mut DirectContext>>, dst_info: &ImageInfo, pixels: &mut [P], dst_row_bytes: usize, src: impl Into<IPoint>, caching_hint: CachingHint, ) -> bool

Copies crate::Rect of pixels from Image to dst_pixels. Copy starts at offset (src_x, src_y), and does not exceed Image (width(), height()).

Graphite has deprecated this API in favor of the equivalent asynchronous API on skgpu::graphite::Context (with an optional explicit synchronization).

dst_info specifies width, height, ColorType, AlphaType, and ColorSpace of destination. dst_row_bytes specifies the gap from one destination row to the next. Returns true if pixels are copied. Returns false if:

• dst_info.addr() equals None
• dst_row_bytes is less than dst_info.min_row_bytes()
• crate::PixelRef is None

Pixels are copied only if pixel conversion is possible. If Image ColorType is ColorType::Gray8, or ColorType::Alpha8; dst_info.color_type() must match. If Image ColorType is ColorType::Gray8, dst_info.color_space() must match. If Image AlphaType is AlphaType::Opaque, dst_info.alpha_type() must match. If Image ColorSpace is None, dst_info.color_space() must match. Returns false if pixel conversion is not possible.

src_x and src_y may be negative to copy only top or left of source. Returns false if width() or height() is zero or negative. Returns false if abs(src_x) >= Image width(), or if abs(src_y) >= Image height().

If caching_hint is CachingHint::Allow, pixels may be retained locally. If caching_hint is CachingHint::Disallow, pixels are not added to the local cache.

• context the gpu::DirectContext in play, if it exists
• dst_info destination width, height, ColorType, AlphaType, ColorSpace
• dst_pixels destination pixel storage
• dst_row_bytes destination row length
• src_x column index whose absolute value is less than width()

• caching_hint whether the pixels should be cached locally

Returns: true if pixels are copied to dst_pixels

pub fn read_pixels_to_pixmap_with_context<'a>( &self, context: impl Into<Option<&'a mut DirectContext>>, dst: &Pixmap<'_>, src: impl Into<IPoint>, caching_hint: CachingHint, ) -> bool

Copies a crate::Rect of pixels from Image to dst. Copy starts at (src_x, src_y), and does not exceed Image (width(), height()).

Graphite has deprecated this API in favor of the equivalent asynchronous API on skgpu::graphite::Context (with an optional explicit synchronization).

dst specifies width, height, ColorType, AlphaType, ColorSpace, pixel storage, and row bytes of destination. dst.row_bytes() specifics the gap from one destination row to the next. Returns true if pixels are copied. Returns false if:

pub fn encode_to_data_with_context( &self, context: impl Into<Option<DirectContext>>, image_format: EncodedImageFormat, quality: impl Into<Option<u32>>, ) -> Option<Data>

👎Deprecated since 0.63.0: Use encode

Encodes Image pixels, returning result as Data.

Returns None if encoding fails, or if encoded_image_format is not supported.

Image encoding in a format requires both building with one or more of: SK_ENCODE_JPEG, SK_ENCODE_PNG, SK_ENCODE_WEBP; and platform support for the encoded format.

If SK_BUILD_FOR_MAC or SK_BUILD_FOR_IOS is defined, encoded_image_format can additionally be one of: EncodedImageFormat::ICO, EncodedImageFormat::BMP, EncodedImageFormat::GIF.

quality is a platform and format specific metric trading off size and encoding error. When used, quality equaling 100 encodes with the least error. quality may be ignored by the encoder.

• context - the gpu::DirectContext in play, if it exists; can be None
• encoded_image_format - one of: EncodedImageFormat::JPEG, EncodedImageFormat::PNG, EncodedImageFormat::WEBP

Returns None if any of the following are true:

• Subset is empty
• Subset is not contained inside the image’s bounds
• Pixels in the image could not be read or copied

If this image is texture-backed, the context parameter is required and must match the context of the source image. If the context parameter is provided, and the image is raster-backed, the subset will be converted to texture-backed.

See Self::new_texture_image_budgeted

pub fn new_texture_image_budgeted( &self, direct_context: &mut DirectContext, mipmapped: Mipmapped, budgeted: Budgeted, ) -> Option<Image>

Returns Image backed by GPU texture associated with context. Returned Image is compatible with crate::Surface created with dst_color_space. The returned Image respects mipmapped setting; if mipmapped equals gpu::Mipmapped::Yes, the backing texture allocates mip map levels.

The mipmapped parameter is effectively treated as No if MIP maps are not supported by the GPU.

Returns original Image if the image is already texture-backed, the context matches, and mipmapped is compatible with the backing GPU texture. crate::Budgeted is ignored in this case.

Returns None if context is None, or if Image was created with another gpu::DirectContext.

• direct_context the gpu::DirectContext in play, if it exists
• mipmapped whether created Image texture must allocate mip map levels
• budgeted whether to count a newly created texture for the returned image counts against the context’s budget.

👎Deprecated since 0.67.0: use images::make_with_filter()

Creates filtered Image. filter processes original Image, potentially changing color, position, and size. subset is the bounds of original Image processed by filter. clip_bounds is the expected bounds of the filtered Image. out_subset is required storage for the actual bounds of the filtered Image. offset is required storage for translation of returned Image.

Returns None if Image could not be created or if the recording context provided doesn’t match the GPU context in which the image was created. If None is returned, out_subset and offset are undefined.

Useful for animation of ImageFilter that varies size from frame to frame. Returned Image is created larger than required by filter so that GPU texture can be reused with different sized effects. out_subset describes the valid bounds of GPU texture returned. offset translates the returned Image to keep subsequent animation frames aligned with respect to each other.

• context the gpu::RecordingContext in play - if it exists

pub fn get_backend_texture( &mut self, handle_access: BackendHandleAccess, ) -> Option<BackendTexture>

👎Deprecated since 0.64.0: use gpu::surfaces::get_backend_texture()

Retrieves the back-end texture. If Surface has no back-end texture, None is returned.

The returned gpu::BackendTexture should be discarded if the Surface is drawn to or deleted.

Returns: GPU texture reference; None on failure

pub fn get_backend_render_target( &mut self, handle_access: BackendHandleAccess, ) -> Option<BackendRenderTarget>

👎Deprecated since 0.64.0: use gpu::surfaces::get_backend_render_target()

Returns: GPU render target reference; None on failure

pub fn replace_backend_texture( &mut self, backend_texture: &BackendTexture, origin: SurfaceOrigin, ) -> bool

If the surface was made via Self::from_backend_texture then it’s backing texture may be substituted with a different texture. The contents of the previous backing texture are copied into the new texture. Canvas state is preserved. The original sample count is used. The gpu::BackendFormat and dimensions of replacement texture must match that of the original.

• backend_texture - the new backing texture for the surface

pub fn replace_backend_texture_with_mode( &mut self, backend_texture: &BackendTexture, origin: SurfaceOrigin, mode: impl Into<Option<ContentChangeMode>>, ) -> bool

If the surface was made via Self::from_backend_texture() then it’s backing texture may be substituted with a different texture. The contents of the previous backing texture are copied into the new texture. Canvas state is preserved. The original sample count is used. The gpu::BackendFormat and dimensions of replacement texture must match that of the original.

• backend_texture - the new backing texture for the surface
• mode - Retain or discard current Content

pub fn canvas(&mut self) -> &Canvas

Returns Canvas that draws into Surface. Subsequent calls return the same Canvas. Canvas returned is managed and owned by Surface, and is deleted when Surface is deleted.

Returns: drawing Canvas for Surface

example: https://fiddle.skia.org/c/@Surface_getCanvas

pub fn new_surface(&mut self, image_info: &ImageInfo) -> Option<Self>

Returns a compatible Surface, or None. Returned Surface contains the same raster, GPU, or null properties as the original. Returned Surface does not share the same pixels.

Returns None if image_info width or height are zero, or if image_info is incompatible with Surface.

• image_info - width, height, crate::ColorType, crate::AlphaType, crate::ColorSpace, of Surface; width and height must be greater than zero

Returns: compatible Surface or None

example: https://fiddle.skia.org/c/@Surface_makeSurface

pub fn new_surface_with_dimensions( &mut self, dim: impl Into<ISize>, ) -> Option<Self>

Calls Self::new_surface() with the same ImageInfo as this surface, but with the specified width and height.

pub fn image_snapshot(&mut self) -> Image

Returns Image capturing Surface contents. Subsequent drawing to Surface contents are not captured. Image allocation is accounted for if Surface was created with gpu::Budgeted::Yes.

Returns: Image initialized with Surface contents

example: https://fiddle.skia.org/c/@Surface_makeImageSnapshot

pub fn image_snapshot_with_bounds( &mut self, bounds: impl AsRef<IRect>, ) -> Option<Image>

Like the no-parameter version, this returns an image of the current surface contents. This variant takes a rectangle specifying the subset of the surface that is of interest. These bounds will be sanitized before being used.

• If bounds extends beyond the surface, it will be trimmed to just the intersection of it and the surface.
• If bounds does not intersect the surface, then this returns None.
• If bounds == the surface, then this is the same as calling the no-parameter variant.

example: https://fiddle.skia.org/c/@Surface_makeImageSnapshot_2

pub fn draw( &mut self, canvas: &Canvas, offset: impl Into<Point>, sampling: impl Into<SamplingOptions>, paint: Option<&Paint>, )

Draws Surface contents to canvas, with its top-left corner at (offset.x, offset.y).

If Paint paint is not None, apply crate::ColorFilter, alpha, crate::ImageFilter, and crate::BlendMode.

• canvas - Canvas drawn into
• offset.x - horizontal offset in Canvas
• offset.y - vertical offset in Canvas
• sampling - what technique to use when sampling the surface pixels
• paint - Paint containing crate::BlendMode, crate::ColorFilter, crate::ImageFilter, and so on; or None

pub fn peek_pixels(&mut self) -> Option<Pixmap<'_>>

pub fn read_pixels_to_pixmap( &mut self, dst: &Pixmap<'_>, src: impl Into<IPoint>, ) -> bool

Copies crate::Rect of pixels to dst.

Source crate::Rect corners are (src.x, src.y) and Surface (width(), height()). Destination crate::Rect corners are (0, 0) and (dst.width(), dst.height()). Copies each readable pixel intersecting both rectangles, without scaling, converting to dst_color_type() and dst_alpha_type() if required.

Pixels are readable when Surface is raster, or backed by a Ganesh GPU backend. Graphite has deprecated this API in favor of the equivalent asynchronous API on skgpu::graphite::Context (with an optional explicit synchonization).

The destination pixel storage must be allocated by the caller.

Pixel values are converted only if crate::ColorType and crate::AlphaType do not match. Only pixels within both source and destination rectangles are copied. dst contents outside crate::Rect intersection are unchanged.

Pass negative values for src.x or src.y to offset pixels across or down destination.

Does not copy, and returns false if:

• Source and destination rectangles do not intersect.
• Pixmap pixels could not be allocated.
• dst.row_bytes() is too small to contain one row of pixels.

• dst - storage for pixels copied from Surface
• src_x - offset into readable pixels on x-axis; may be negative
• src_y - offset into readable pixels on y-axis; may be negative

Returns: true if pixels were copied

example: https://fiddle.skia.org/c/@Surface_readPixels

pub fn read_pixels( &mut self, dst_info: &ImageInfo, dst_pixels: &mut [u8], dst_row_bytes: usize, src: impl Into<IPoint>, ) -> bool

• dst_row_bytes - size of one destination row; dst_info.width() times pixel size, or larger
• src.x - offset into readable pixels on x-axis; may be negative
• src.y - offset into readable pixels on y-axis; may be negative

Returns: true if pixels were copied

pub fn resolve_msaa(&mut self)

👎Deprecated since 0.65.0: Use gpu::surfaces::resolve_msaa

If a surface is GPU texture backed, is being drawn with MSAA, and there is a resolve texture, this call will insert a resolve command into the stream of gpu commands. In order for the resolve to actually have an effect, the work still needs to be flushed and submitted to the GPU after recording the resolve command. If a resolve is not supported or the Surface has no dirty work to resolve, then this call is a no-op.

This call is most useful when the Surface is created by wrapping a single sampled gpu texture, but asking Skia to render with MSAA. If the client wants to use the wrapped texture outside of Skia, the only way to trigger a resolve is either to call this command or use Self::flush().
