Struct GLProcessorThreaded 

pub struct GLProcessorThreaded { /* private fields */ }

OpenGL multi-threaded image converter. The actual conversion is done in a separate rendering thread, as OpenGL contexts are not thread-safe. This can be safely sent between threads. The convert() call sends the conversion request to the rendering thread and waits for the result.

Implementations

impl GLProcessorThreaded

pub fn new(kind: Option<EglDisplayKind>) -> Result<Self, Error>

Creates a new OpenGL multi-threaded image converter.

impl GLProcessorThreaded

pub fn set_int8_interpolation_mode( &mut self, mode: Int8InterpolationMode, ) -> Result<(), Error>

Sets the interpolation mode for int8 proto textures.

pub fn decode_masks_atlas( &mut self, detect: &[DetectBox], proto_data: ProtoData, output_width: usize, output_height: usize, ) -> Result<(Vec<u8>, Vec<MaskRegion>), Error>

Decode all detection masks into a compact atlas via the GL thread.

Returns (atlas_pixels, regions) where atlas_pixels is a contiguous Vec<u8> of shape [atlas_h, output_width] (compact, bbox-sized strips) and regions describes each detection’s location within the atlas.

pub fn create_pbo_image( &self, width: usize, height: usize, format: PixelFormat, ) -> Result<Tensor<u8>, Error>

Create a PBO-backed [Tensor<u8>] image on the GL thread.

Trait Implementations

impl Debug for GLProcessorThreaded

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

Formats the value using the given formatter.

impl Drop for GLProcessorThreaded

fn drop(&mut self)

Executes the destructor for this type.

impl ImageProcessorTrait for GLProcessorThreaded

fn convert( &mut self, src: &TensorDyn, dst: &mut TensorDyn, rotation: Rotation, flip: Flip, crop: Crop, ) -> Result<()>

Converts the source image to the destination image format and size. The image is cropped first, then flipped, then rotated

fn draw_masks( &mut self, dst: &mut TensorDyn, detect: &[DetectBox], segmentation: &[Segmentation], ) -> Result<()>

Draw pre-decoded detection boxes and segmentation masks onto dst.

fn draw_masks_proto( &mut self, dst: &mut TensorDyn, detect: &[DetectBox], proto_data: &ProtoData, ) -> Result<()>

Draw masks from proto data onto image (fused decode+draw).

fn decode_masks_atlas( &mut self, detect: &[DetectBox], proto_data: ProtoData, output_width: usize, output_height: usize, ) -> Result<(Vec<u8>, Vec<MaskRegion>)>

Decode masks into a compact atlas buffer.

fn set_class_colors(&mut self, colors: &[[u8; 4]]) -> Result<(), Error>

Sets the colors used for rendering segmentation masks. Up to 20 colors can be set.
