Variables ¶
var ErrorFrameTypeNotPresent = errors.New("The frame type you requested is not present in this CommonFrame")
ErrorFrameTypeNotPresent is returned when the user asked to Get an underlying GetNativeFrame or GetEncapsulatedFrame that is not contained in that particular CommonFrame.

Types ¶
type CommonFrame ¶
type CommonFrame interface {
// GetImage gets this frame as an image.Image. Beware that the underlying frame may perform
// some default rendering and conversions. Operate on the raw NativeFrame or EncapsulatedFrame
// if you need to do some custom rendering work or want the data from the dicom.
GetImage() (image.Image, error)
// Encapsulated indicates if the underlying Frame is an EncapsulatedFrame
IsEncapsulated() bool
// GetNativeFrame attempts to get the underlying NativeFrame (or returns an error)
GetNativeFrame() (*NativeFrame, error)
// GetEncapsulatedFrame attempts to get the underlying EncapsulatedFrame (or returns an error)
GetEncapsulatedFrame() (*EncapsulatedFrame, error)
}
CommonFrame represents a harmonized DICOM Frame with a consistent interface (harmonized across Native and Encapsulated frames), however users still have the ability to fetch underlying Native or Encapsulated frame constructs.
type EncapsulatedFrame ¶
type EncapsulatedFrame struct {
// Data is a collection of bytes representing a JPEG encoded image frame
Data []byte
}
EncapsulatedFrame represents an encapsulated image frame
func (*EncapsulatedFrame) GetEncapsulatedFrame ¶
func (e *EncapsulatedFrame) GetEncapsulatedFrame() (*EncapsulatedFrame, error)
func (*EncapsulatedFrame) GetNativeFrame ¶
func (e *EncapsulatedFrame) GetNativeFrame() (*NativeFrame, error)
func (*EncapsulatedFrame) IsEncapsulated ¶
func (e *EncapsulatedFrame) IsEncapsulated() bool
type Frame ¶
type Frame struct {
Encapsulated bool
EncapsulatedData EncapsulatedFrame
NativeData NativeFrame
FileOffset int64
SizeInBytes int
}
Frame wraps a single encapsulated or native image frame TODO: deprecate this old intermediate representation in favor of CommonFrame once happy and solid with API
func (*Frame) GetEncapsulatedFrame ¶
func (f *Frame) GetEncapsulatedFrame() (*EncapsulatedFrame, error)
func (*Frame) GetNativeFrame ¶
func (f *Frame) GetNativeFrame() (*NativeFrame, error)
func (*Frame) IsEncapsulated ¶
type NativeFrame ¶
type NativeFrame struct {
// Data is a slice of pixels, where each pixel can have multiple values
Data [][]int
Rows int
Cols int
BitsPerSample int
}
NativeFrame represents a native image frame
func (*NativeFrame) GetEncapsulatedFrame ¶
func (n *NativeFrame) GetEncapsulatedFrame() (*EncapsulatedFrame, error)
func (*NativeFrame) GetImage ¶
func (n *NativeFrame) GetImage() (image.Image, error)
GetImage returns an image.Image representation the frame, using default processing. This default processing is basic at the moment, and does not autoscale pixel values or use window width or level info.
func (*NativeFrame) GetNativeFrame ¶
func (n *NativeFrame) GetNativeFrame() (*NativeFrame, error)
func (*NativeFrame) IsEncapsulated ¶
func (n *NativeFrame) IsEncapsulated() bool
