Functions

func DetectText

func DetectText(file string) ([]*visionpb.EntityAnnotation, []*visionpb.LocalizedObjectAnnotation, error)

DetectText sends image to GCP Cloud Vision for processing and annotating

func RequestImageAnnotation

func RequestImageAnnotation(file string) (*visionpb.AnnotateImageResponse, error)

RequestImageAnnotation sends several options to GCP Cloud Vision for processing and annotating

Types

type Annotation

type Annotation struct {
	Description  string       `json:"description"`
	BoundingPoly BoundingPoly `json:"boundingPoly"`
}

Annotation stores Description and BoundingPoly of Description as 'text'

type BoundingPoly

type BoundingPoly struct {
	//using google's generated protobuf.. probably should do this for the other structs if this works
	Vertices []*visionpb.Vertex `json:"vertices"`
}

BoundingPoly stores array of 4 XY coordinates that make up a polygon

type ImageAnnotation

type ImageAnnotation struct {
	DirPath           string        `json:"dirPath"`
	FileName          string        `json:"filename"`
	FileExtension     string        `json:"fileExtension"`
	TextAnnotations   []*Annotation `json:"text"`
	ObjectAnnotations []*Annotation `json:"object"`
}

ImageAnnotation stores data returned from Cloud Vision along with image file metadata

func NewImageAnnotation

func NewImageAnnotation(filename string) *ImageAnnotation

NewImageAnnotation creates a new ImageAnnotation from filename and extension

type Vertex

type Vertex struct {
	X int `json:"x"`
	Y int `json:"y"`
}

Vertex stores X, Y points
