Struct ImageProcessorConfig 

pub struct ImageProcessorConfig {
    pub egl_display: Option<EglDisplayKind>,
    pub backend: ComputeBackend,
    pub colorimetry: ColorimetryMode,
}

Configuration for ImageProcessor construction.

Use with ImageProcessor::with_config to override the default EGL display auto-detection and backend selection. The default configuration preserves the existing auto-detection behaviour.

Fields

egl_display: Option<EglDisplayKind>

Force OpenGL to use this EGL display type instead of auto-detecting.

When None, the processor probes displays in priority order: GBM, PlatformDevice, Default. Use probe_egl_displays to discover which displays are available on the current system.

Ignored when EDGEFIRST_DISABLE_GL=1 is set, and on macOS (ANGLE/Metal is the only display there; a Some value logs a debug note and is otherwise ignored).

backend: ComputeBackend

Preferred compute backend.

When set to a specific backend (not ComputeBackend::Auto), the processor initializes that backend with no fallback — returns an error if the conversion is not supported. This takes precedence over EDGEFIRST_FORCE_BACKEND and the EDGEFIRST_DISABLE_* environment variables.

• ComputeBackend::OpenGl: init OpenGL + CPU, skip G2D
• ComputeBackend::G2d: init G2D + CPU, skip OpenGL
• ComputeBackend::Cpu: init CPU only
• ComputeBackend::Auto: existing env-var-driven selection

colorimetry: ColorimetryMode

Colorimetry/performance trade-off for convert() (see ColorimetryMode). Defaults to ColorimetryMode::Fast. The EDGEFIRST_COLORIMETRY environment variable (fast | exact) overrides this setting when present.
