Hi,

Could you please provide more details on the issue? What do you mean by "open image with Stream"?

To load an image data coming from other APIs you can use the imaging.Decode function that takes an io.Reader as its first argument. If you're working with the Google Cloud Storage, you can use the NewReader method of the ObjectHandle to get the reader of the object data. (https://pkg.go.dev/cloud.google.com/go/storage?tab=doc#ObjectHandle.NewReader)

Hi,

I'm looking for something similar. I would like to stream an image from one bucket, resize it and stream it into another bucket. This article explains exactly what I'm trying to achieve.

I'm not very familiar with Google Cloud Storage. Looking at the docs, you can do a similar processing in Go:

Create a new reader of the source image object (https://pkg.go.dev/cloud.google.com/go/storage?tab=doc#ObjectHandle.NewReader)
Create a new writer to the destination image object in another bucket (https://pkg.go.dev/cloud.google.com/go/storage?tab=doc#ObjectHandle.NewWriter)
Use imaging.Decode function to read the image from the reader.
Use imaging.Resize to resize the image.
Use imaging.Encode to write the resized image to the writer.
