Struct GraphicData 

pub struct GraphicData {
    pub id: GraphicId,
    pub width: usize,
    pub height: usize,
    pub color_type: ColorType,
    pub pixels: Vec<u8>,
    pub is_opaque: bool,
    pub resize: Option<ResizeCommand>,
    pub display_width: Option<usize>,
    pub display_height: Option<usize>,
    pub transmit_time: Instant,
}

Defines a single graphic read from the PTY.

Fields

id: GraphicId

Graphics identifier.

width: usize

Width, in pixels, of the graphic.

height: usize

Height, in pixels, of the graphic.

color_type: ColorType

Color type of the pixels.

pixels: Vec<u8>

Pixels data.

is_opaque: bool

Indicate if there are no transparent pixels.

resize: Option<ResizeCommand>

Render graphic in a different size.

display_width: Option<usize>

Display width in pixels (set when GPU scaling is used instead of CPU resize). If None, display at the original pixel width.

display_height: Option<usize>

Display height in pixels (set when GPU scaling is used instead of CPU resize). If None, display at the original pixel height.

transmit_time: Instant

Generation counter for cache invalidation. Incremented when image data changes (re-transmission with same ID).

Implementations

impl GraphicData

pub fn maybe_transparent(&self) -> bool

Check if the image may contain transparent pixels. If it returns false, it is guaranteed that there are no transparent pixels.

pub fn is_filled(&self, x: usize, y: usize, width: usize, height: usize) -> bool

Check if all pixels under a region are opaque.

If the region exceeds the boundaries of the image it is considered as not filled.

pub fn compute_display_dimensions( &self, cell_width: usize, cell_height: usize, view_width: usize, view_height: usize, ) -> (usize, usize)

Compute the display dimensions for this graphic without modifying pixels. Returns (display_width, display_height) in pixels. If no resize is needed, returns the original dimensions.

Trait Implementations
