Struct jxl_render::RenderContext

pub struct RenderContext { /* private fields */ }

Render context that tracks loaded and rendered frames.

Implementations

impl RenderContext

pub fn builder() -> RenderContextBuilder

impl RenderContext

pub fn alloc_tracker(&self) -> Option<&AllocTracker>

impl RenderContext

pub fn set_cms( &mut self, cms: impl ColorManagementSystem + Send + Sync + 'static )

pub fn request_color_encoding(&mut self, encoding: ColorEncodingWithProfile)

pub fn requested_color_encoding(&self) -> &ColorEncodingWithProfile

pub fn request_image_region(&mut self, image_region: Region)

impl RenderContext

pub fn width(&self) -> u32

Returns the image width.

pub fn height(&self) -> u32

Returns the image height.

pub fn embedded_icc(&self) -> Option<&[u8]>

pub fn loaded_keyframes(&self) -> usize

Returns the number of loaded keyframes in the context.

pub fn loaded_frames(&self) -> usize

Returns the number of loaded frames in the context, including frames that are not shown directly.

impl RenderContext

pub fn load_frame_header( &mut self, bitstream: &mut Bitstream<'_> ) -> Result<&mut IndexedFrame>

pub fn current_loading_frame(&mut self) -> Option<&mut IndexedFrame>

pub fn finalize_current_frame(&mut self)

impl RenderContext

pub fn keyframe(&self, keyframe_idx: usize) -> Option<&IndexedFrame>

Returns the frame with the keyframe index, or None if the keyframe does not exist.

pub fn frame(&self, frame_idx: usize) -> Option<&IndexedFrame>

impl RenderContext

pub fn render(&mut self) -> Result<ImageWithRegion>

Renders the first keyframe.

The keyframe should be loaded in prior to rendering, with one of the loading methods.

pub fn render_keyframe(&self, keyframe_idx: usize) -> Result<ImageWithRegion>

Renders the keyframe.

The keyframe should be loaded in prior to rendering, with one of the loading methods.

pub fn render_loading_keyframe( &mut self ) -> Result<(&IndexedFrame, ImageWithRegion)>

pub fn reset_cache(&mut self)

Trait Implementations

impl Debug for RenderContext

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
