Help with binary data to image IronPython script

Recommended Posts

I modified the code in the article below to read data from a BLOB document property but I get an "Invalid Parameter" error at the Image.FromStream(stream) line.

The BLOB in question is a Bitmap saved as PNG image type that is written to the document property by a similar IronPython script. The image is correctly rendered as a label in a text area.

from Spotfire.Dxp.Data import *

from System.IO import *

from System.Drawing import *

from System.Drawing.Imaging import *

blob = Document.Properties["myImage"]

stream=blob.GetByteStream()

img=Image.FromStream(stream)

#img=Image.FromStream(stream,0,1)
