Graphics renderer for sixel images

Implementations

impl GraphicsRenderer

pub fn new( device: &Device, surface_format: TextureFormat, cell_width: f32, cell_height: f32, window_padding: f32, scaling_mode: ImageScalingMode, preserve_aspect_ratio: bool, ) -> Result<Self>

Create a new graphics renderer

pub fn get_or_create_texture( &mut self, device: &Device, queue: &Queue, id: u64, rgba_data: &[u8], width: u32, height: u32, ) -> Result<()>

Create or get a cached texture for a sixel graphic

Arguments

• device - WGPU device for creating textures
• queue - WGPU queue for writing texture data
• id - Unique identifier for this sixel graphic
• rgba_data - RGBA pixel data (width * height * 4 bytes)
• width - Image width in pixels
• height - Image height in pixels

pub fn render( &mut self, device: &Device, queue: &Queue, render_pass: &mut RenderPass<'_>, graphics: &[(u64, isize, usize, usize, usize, f32, usize)], window_width: f32, window_height: f32, ) -> Result<()>

Render sixel graphics

Arguments

• device - WGPU device for creating buffers
• queue - WGPU queue for writing buffer data
• render_pass - Active render pass to render into
• graphics - Slice of sixel graphics to render with their positions Each tuple contains: (id, row, col, width_in_cells, height_in_cells, alpha, scroll_offset_rows)
• window_width - Window width in pixels
• window_height - Window height in pixels

pub fn render_for_pane( &mut self, device: &Device, queue: &Queue, render_pass: &mut RenderPass<'_>, graphics: &[(u64, isize, usize, usize, usize, f32, usize)], window_width: f32, window_height: f32, pane_origin_x: f32, pane_origin_y: f32, ) -> Result<()>

Render sixel graphics for a specific pane using explicit origin coordinates.

Identical to [render] but uses pane_origin_x/pane_origin_y for positioning instead of the global window_padding + content_offset values, so graphics are placed relative to the pane rather than the full window.

Arguments

• device - WGPU device for creating buffers
• queue - WGPU queue for writing buffer data
• render_pass - Active render pass to render into
• graphics - Slice of sixel graphics to render with their positions
• window_width - Window width in pixels
• window_height - Window height in pixels
• pane_origin_x - X pixel coordinate of the pane’s content origin
• pane_origin_y - Y pixel coordinate of the pane’s content origin

pub fn remove_texture(&mut self, id: u64)

Remove a texture from the cache

pub fn clear_cache(&mut self)

Clear all cached textures

pub fn cache_size(&self) -> usize

Get the number of cached textures

pub fn update_cell_dimensions( &mut self, cell_width: f32, cell_height: f32, window_padding: f32, )

Update cell dimensions (called when window is resized)

pub fn set_content_offset_y(&mut self, offset: f32)

Set vertical content offset (e.g., tab bar height)

pub fn set_content_offset_x(&mut self, offset: f32)

Set horizontal content offset (e.g., tab bar on left)

pub fn set_preserve_aspect_ratio(&mut self, preserve: bool)

Update the global aspect ratio preservation setting.

pub fn update_scaling_mode( &mut self, device: &Device, scaling_mode: ImageScalingMode, )

Update the texture scaling mode (nearest vs linear filtering).

This recreates the sampler and invalidates all cached textures since their bind groups reference the old sampler.
