Implementations

impl PixmapDevice

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

pub fn set_clip_path( &mut self, path: &Path, fill_rule: FillRule, transform: Transform, )

Set a clipping path (replaces existing clip).

pub fn intersect_clip_path( &mut self, path: &Path, fill_rule: FillRule, transform: Transform, )

Intersect the current clip with another path.

pub fn clear_clip(&mut self)

Clear the clip mask.

pub fn fill_path( &mut self, path: &Path, fill_rule: FillRule, transform: Transform, color: [u8; 4], blend_mode: BlendMode, )

Fill a path.

pub fn stroke_path( &mut self, path: &Path, transform: Transform, color: [u8; 4], gs: &GraphicsState, blend_mode: BlendMode, )

Stroke a path.

pub fn draw_image( &mut self, image_pixmap: &PixmapRef<'_>, transform: Transform, alpha: f32, blend_mode: BlendMode, )

Draw an RGBA image at the given transform.

pub fn draw_pixmap( &mut self, src: &PixmapRef<'_>, transform: Transform, alpha: f32, blend_mode: BlendMode, )

Draw a pixmap onto this device (for transparency group compositing).

pub fn fill_path_with_pattern( &mut self, path: &Path, fill_rule: FillRule, transform: Transform, pattern_pixmap: &PixmapRef<'_>, pattern_transform: Transform, blend_mode: BlendMode, )

Fill a path with a pattern (tiled pixmap).

pub fn stroke_path_with_pattern( &mut self, path: &Path, transform: Transform, gs: &GraphicsState, pattern_pixmap: &PixmapRef<'_>, pattern_transform: Transform, blend_mode: BlendMode, )

Stroke a path with a pattern (tiled pixmap).

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

Fill the entire pixmap with a color.

pub fn encode_png(&self) -> Result<Vec<u8>>

Encode the pixmap as PNG bytes.

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

Get the raw RGBA pixel data.

pub fn dimensions(&self) -> (u32, u32)

Get the pixmap dimensions (width, height).

pub fn encode_jpeg(&self, quality: u8) -> Result<Vec<u8>>

Encode the pixmap as JPEG bytes.
