B4J Question jServer - ServletResponse how to send a image as response

Alexander Stolte · Jul 22, 2020

Hey,
how can I return an image correctly so that it can be evaluated as an image and used in BitmapAsync "LoadFromHttpJob" for example?
What do I have to convert it to?

If the image come from a file then the best option is to put it in the static files folder (www\* by default) and it will be downloaded automatically.

Other option:

B4X:

Dim b() As Byte = File.ReadBytes(...)
resp.OutputStream.WriteBytes(b, 0, b.Length)
