Struct G2DProcessor 

pub struct G2DProcessor { /* private fields */ }

G2DConverter implements the ImageProcessor trait using the NXP G2D library for hardware-accelerated image processing on i.MX platforms.

Implementations

impl G2DProcessor

pub fn new() -> Result<Self>

Creates a new G2DConverter instance.

The BT.709 matrix set here is only a safe default; each convert() call re-programs the matrix from the resolved colorimetry of the YUV side of that conversion (see convert_impl). G2D is matrix-only — it has no range control (limited-range only) and no BT.2020 matrix — so full-range YUV and BT.2020 conversions are declined and fall through to GL/CPU.

pub fn version(&self) -> Version

Returns the G2D library version as defined by _G2D_VERSION in the shared library.

Trait Implementations

impl Debug for G2DProcessor

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

Formats the value using the given formatter.

impl ImageProcessorTrait for G2DProcessor

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_decoded_masks( &mut self, dst: &mut TensorDyn, detect: &[DetectBox], segmentation: &[Segmentation], overlay: MaskOverlay<'_>, ) -> Result<()>

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

fn draw_proto_masks( &mut self, dst: &mut TensorDyn, detect: &[DetectBox], _proto_data: &ProtoData, overlay: MaskOverlay<'_>, ) -> Result<()>

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

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

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

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

Like convert, but does not wait for the GPU to finish.

fn flush(&mut self) -> Result<()>

Complete all work enqueued by convert_deferred since the last flush, issuing a single GPU synchronization.
