Types ¶
type CaptureArgs ¶
type CaptureArgs struct {
PixelFormat int32
SourceCrop ARect
FrameScaleX float32
FrameScaleY float32
CaptureSecureLayers bool
Uid int32
Dataspace int32
AllowProtected bool
Grayscale bool
ExcludeHandles []binder.IBinder
HintForSeamlessTransition bool
}
CaptureArgs contains common arguments for screen capture operations.
Wire format matches the custom C++ serialization in frameworks/native/libs/gui/LayerState.cpp CaptureArgs::writeToParcel. This is a cpp_header parcelable with flat (non-AIDL-structured) layout: no parcelable header/footer, no null indicators for embedded types. The C++ Rect (sourceCrop) is written as 4 raw int32s, not as an AIDL structured parcelable.
func (*CaptureArgs) MarshalParcel ¶
func (s *CaptureArgs) MarshalParcel( p *parcel.Parcel, ) error
func (*CaptureArgs) UnmarshalParcel ¶
func (s *CaptureArgs) UnmarshalParcel( p *parcel.Parcel, ) error
type LayerCaptureArgs ¶
type LayerCaptureArgs struct {
CaptureArgs CaptureArgs
LayerHandle binder.IBinder
ChildrenOnly bool
}
LayerCaptureArgs contains arguments for capturing a layer and its children.
Wire format matches the custom C++ serialization in frameworks/native/libs/gui/LayerState.cpp LayerCaptureArgs::writeToParcel. This is a cpp_header parcelable with flat layout: no parcelable header/footer, no null indicators. The C++ struct inherits from CaptureArgs, so writeToParcel first calls CaptureArgs::writeToParcel (inline, not wrapped in a null indicator), then writes its own fields.
func (*LayerCaptureArgs) MarshalParcel ¶
func (s *LayerCaptureArgs) MarshalParcel( p *parcel.Parcel, ) error
func (*LayerCaptureArgs) UnmarshalParcel ¶
func (s *LayerCaptureArgs) UnmarshalParcel( p *parcel.Parcel, ) error
type ScreenCaptureResults ¶
type ScreenCaptureResults struct {
// Buffer contains the captured pixels as a gralloc GraphicBuffer.
// Nil if capture failed.
Buffer *gralloc.Buffer
// CapturedSecureLayers indicates if secure content was captured.
CapturedSecureLayers bool
// CapturedHdrLayers indicates if HDR content was captured.
CapturedHdrLayers bool
// CapturedDataspace is the dataspace of the captured content.
CapturedDataspace uint32
// HdrSdrRatio is the HDR/SDR luminance ratio.
HdrSdrRatio float32
}
ScreenCaptureResults holds the result of a SurfaceFlinger screen capture. The wire format is defined in C++ (ScreenCaptureResults.cpp), not AIDL.
func (*ScreenCaptureResults) MarshalParcel ¶
func (s *ScreenCaptureResults) MarshalParcel( p *parcel.Parcel, ) error
func (*ScreenCaptureResults) UnmarshalParcel ¶
func (s *ScreenCaptureResults) UnmarshalParcel( p *parcel.Parcel, ) error
