I am facing problem to show base64 image to poster node.
please guys help us on this issue.

sub load_Map(json As Object)

json=parseJSON(json)
remove_n=json.MapFlightResult
print"remove Before========>>>>"remove_n

r = CreateObject(“roRegex”,“\n”, “i”)
remove_new=r.ReplaceAll(remove_n,“”)
print"remove After========>>>>"remove_new

ba=CreateObject(“roByteArray”)
ba.FromBase64String(remove_new)
img=ba.ToAsciiString()
print"img=======>>>>>"img
m.Map.uri=img
m.Map.visible=true
end sub

thanks in advance to All Roku Team.

You’re looking for something like this:

uri = "tmp:/images/" + someidentifier
ba = CreateObject("roByteArray")
ba.fromBase64String(yourbase64string)
ba.writeFile(uri)

poster.uri = uri

What I do for the sake of speed is write an external php script to handle the code as Roku gets bogged down real quick.
