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)
