Struct tiny_skia::Pixmap

source ·
pub struct Pixmap { /* private fields */ }
Expand description

A container that owns premultiplied RGBA pixels.

The data is not aligned, therefore width == stride.

Implementations§

source§

impl Pixmap

source

pub fn new(width: u32, height: u32) -> Option<Self>

Allocates a new pixmap.

A pixmap is filled with transparent black by default, aka (0, 0, 0, 0).

Zero size in an error.

Pixmap’s width is limited by i32::MAX/4.

source

pub fn from_vec(data: Vec<u8>, size: IntSize) -> Option<Self>

Creates a new pixmap by taking ownership over an image buffer (premultiplied RGBA pixels).

The size needs to match the data provided.

Pixmap’s width is limited by i32::MAX/4.

source

pub fn as_ref(&self) -> PixmapRef<'_>

Returns a container that references Pixmap’s data.

source

pub fn as_mut(&mut self) -> PixmapMut<'_>

Returns a container that references Pixmap’s data.

source

pub fn width(&self) -> u32

Returns pixmap’s width.

source

pub fn height(&self) -> u32

Returns pixmap’s height.

source

pub fn fill(&mut self, color: Color)

Fills the entire pixmap with a specified color.

source

pub fn data(&self) -> &[u8]

Returns the internal data.

Byteorder: RGBA

source

pub fn data_mut(&mut self) -> &mut [u8]

Returns the mutable internal data.

Byteorder: RGBA

source

pub fn pixel(&self, x: u32, y: u32) -> Option<PremultipliedColorU8>

Returns a pixel color.

Returns None when position is out of bounds.

source

pub fn pixels_mut(&mut self) -> &mut [PremultipliedColorU8]

Returns a mutable slice of pixels.

source

pub fn pixels(&self) -> &[PremultipliedColorU8]

Returns a slice of pixels.

source

pub fn take(self) -> Vec<u8>

Consumes the internal data.

Byteorder: RGBA

source

pub fn clone_rect(&self, rect: IntRect) -> Option<Pixmap>

Returns a copy of the pixmap that intersects the rect.

Returns None when Pixmap’s rect doesn’t contain rect.

source§

impl Pixmap

source

pub fn fill_rect( &mut self, rect: Rect, paint: &Paint<'_>, transform: Transform, mask: Option<&Mask> )

Draws a filled rectangle onto the pixmap.

See PixmapMut::fill_rect for details.

source

pub fn fill_path( &mut self, path: &Path, paint: &Paint<'_>, fill_rule: FillRule, transform: Transform, mask: Option<&Mask> )

Draws a filled path onto the pixmap.

See PixmapMut::fill_path for details.

source

pub fn stroke_path( &mut self, path: &Path, paint: &Paint<'_>, stroke: &Stroke, transform: Transform, mask: Option<&Mask> )

Strokes a path.

See PixmapMut::stroke_path for details.

source

pub fn draw_pixmap( &mut self, x: i32, y: i32, pixmap: PixmapRef<'_>, paint: &PixmapPaint, transform: Transform, mask: Option<&Mask> )

Draws a Pixmap on top of the current Pixmap.

See PixmapMut::draw_pixmap for details.

source

pub fn apply_mask(&mut self, mask: &Mask)

Applies a masks.

See PixmapMut::apply_mask for details.

impl PartialEq for Pixmap

source§

fn eq(&self, other: &Pixmap) -> bool
