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 set_interpolation(&mut self, mode: Interpolation)

Sets how resizing converts resample (see crate::Interpolation). G2D scales with a fixed hardware filter, so under crate::Interpolation::Nearest it declines converts that resize and leaves them to a backend that can sample nearest-neighbour.

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, options: Option<ConvertOptions>, ) -> Result<()>

Convert src into dst’s format and size, applying the crop first, then the flip, then the rotation.

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 RGBA colors used for rendering segmentation masks and bounding boxes. Up to 20 colors can be set; entries past the slice keep their previous value.

fn set_box_line_width(&mut self, _: u32) -> Result<()>

Sets the thickness, in destination pixels, of the bounding-box outlines drawn by draw_decoded_masks and draw_proto_masks. The default is DEFAULT_BOX_LINE_WIDTH (3 px).

fn convert_deferred( &mut self, src: &TensorDyn, dst: &mut TensorDyn, options: Option<ConvertOptions>, ) -> 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.
