Struct tiny_skia::PixmapMut [−][src]
A container that references mutable premultiplied RGBA pixels.
Can be created from Pixmap
or from a user provided data.
The data is not aligned, therefore width == stride.
Implementations
impl<'a> PixmapMut<'a>
[src]
pub fn from_bytes(data: &'a mut [u8], width: u32, height: u32) -> Option<Self>
[src]
Creates a new PixmapMut
from bytes.
The size must be at least size.width() * size.height() * BYTES_PER_PIXEL
.
Zero size in an error. Width is limited by i32::MAX/4.
The data
is assumed to have premultiplied RGBA pixels (byteorder: RGBA).
pub fn to_owned(&self) -> Pixmap
[src]
Creates a new Pixmap
from the current data.
Clones the underlying data.
pub fn as_ref(&self) -> PixmapRef<'_>
[src]
Returns a container that references Pixmap’s data.
pub fn width(&self) -> u32
[src]
Returns pixmap’s width.
pub fn height(&self) -> u32
[src]
Returns pixmap’s height.
pub fn fill(&mut self, color: Color)
[src]
Fills the entire pixmap with a specified color.
pub fn data_mut(&mut self) -> &mut [u8]
[src]
Returns the mutable internal data.
Byteorder: RGBA
pub fn pixels_mut(&mut self) -> &mut [PremultipliedColorU8]
[src]
Returns a mutable slice of pixels.
impl PixmapMut<'_>
[src]
pub fn fill_rect(
&mut self,
rect: Rect,
paint: &Paint<'_>,
transform: Transform,
clip_mask: Option<&ClipMask>
) -> Option<()>
[src]
&mut self,
rect: Rect,
paint: &Paint<'_>,
transform: Transform,
clip_mask: Option<&ClipMask>
) -> Option<()>
Draws a filled rectangle onto the pixmap.
This function is usually slower than filling a rectangular path, but it produces better results. Mainly it doesn’t suffer from weird clipping of horizontal/vertical edges.
Used mainly to render a pixmap onto a pixmap.
Returns None
when there is nothing to fill or in case of a numeric overflow.
pub fn fill_path(
&mut self,
path: &Path,
paint: &Paint<'_>,
fill_rule: FillRule,
transform: Transform,
clip_mask: Option<&ClipMask>
) -> Option<()>
[src]
&mut self,
path: &Path,
paint: &Paint<'_>,
fill_rule: FillRule,
transform: Transform,
clip_mask: Option<&ClipMask>
) -> Option<()>
Draws a filled path onto the pixmap.
Returns None
when there is nothing to fill or in case of a numeric overflow.
pub fn stroke_path(
&mut self,
path: &Path,
paint: &Paint<'_>,
stroke: &Stroke,
transform: Transform,
clip_mask: Option<&ClipMask>
) -> Option<()>
[src]
&mut self,
path: &Path,
paint: &Paint<'_>,
stroke: &Stroke,
transform: Transform,
clip_mask: Option<&ClipMask>
) -> Option<()>
Strokes a path.
Stroking is implemented using two separate algorithms:
- If a stroke width is wider than 1px (after applying the transformation),
a path will be converted into a stroked path and then filled using
Canvas::fill_path
. Which means that we have to allocate a separatePath
, that can be 2-3x larger then the original path.Canvas
will reuse this allocation during subsequent strokes. - If a stroke width is thinner than 1px (after applying the transformation), we will use hairline stroking, which doesn’t involve a separate path allocation.
Also, if a stroke
has a dash array, then path will be converted into
a dashed path first and then stroked. Which means a yet another allocation.
pub fn draw_pixmap(
&mut self,
x: i32,
y: i32,
pixmap: PixmapRef<'_>,
paint: &PixmapPaint,
transform: Transform,
clip_mask: Option<&ClipMask>
) -> Option<()>
[src]
&mut self,
x: i32,
y: i32,
pixmap: PixmapRef<'_>,
paint: &PixmapPaint,
transform: Transform,
clip_mask: Option<&ClipMask>
) -> Option<()>
Draws a Pixmap
on top of the current Pixmap
.
We basically filling a rectangle with a pixmap
pattern.
