Overview

Package imagedata enables management of image data.

Example to Upload Image Data

imageID := "da3b75d9-3f4a-40e7-8a2c-bfab23927dea"

imageData, err := os.Open("/path/to/image/file")
if err != nil {
	panic(err)
}
defer imageData.Close()

err = imagedata.Upload(imageClient, imageID, imageData).ExtractErr()
if err != nil {
	panic(err)
}

Example to Stage Image Data

imageID := "da3b75d9-3f4a-40e7-8a2c-bfab23927dea"

imageData, err := os.Open("/path/to/image/file")
if err != nil {
  panic(err)
}
defer imageData.Close()

err = imagedata.Stage(imageClient, imageID, imageData).ExtractErr()
if err != nil {
  panic(err)
}

Example to Download Image Data

imageID := "da3b75d9-3f4a-40e7-8a2c-bfab23927dea"

image, err := imagedata.Download(imageClient, imageID).Extract()
if err != nil {
	panic(err)
}

imageData, err := ioutil.ReadAll(image)
if err != nil {
	panic(err)
}

Types

type DownloadResult

type DownloadResult struct {
	golangsdk.Result
	// contains filtered or unexported fields
}

DownloadResult is the result of a download image operation. Call its Extract method to gain access to the image data.

func Download

func Download(client *golangsdk.ServiceClient, id string) (r DownloadResult)

Download retrieves an image.

func (DownloadResult) Extract

func (r DownloadResult) Extract() (io.ReadCloser, error)

Extract builds images model from io.Reader

type StageResult

type StageResult struct {
	golangsdk.ErrResult
}

StageResult is the result of a stage image operation. Call its ExtractErr method to determine if the request succeeded or failed.

func Stage

func Stage(client *golangsdk.ServiceClient, id string, data io.Reader) (r StageResult)

Stage performs PUT call on the existing image object in the Imageservice with the provided file. Existing image object must be in the "queued" status.

type UploadResult

type UploadResult struct {
	golangsdk.ErrResult
}

UploadResult is the result of an upload image operation. Call its ExtractErr method to determine if the request succeeded or failed.

func Upload

func Upload(client *golangsdk.ServiceClient, id string, data io.Reader) (r UploadResult)

Upload uploads an image file.
