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)
}

// close the reader, when reading has finished
defer image.Close()

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