Export images to a specific folder via Ironpython

Hi everyone! I'm using the following code to export image from spotfire to a folder, which will be selected. the code shows me no errors but the image is not saved in the folder!! It may be a path problem. Your help will be very appreciated.

That's the code:

 

import System

import clr

clr.AddReference("System.Windows.Forms")

from System import *

from System.IO import *

from System.Drawing import Bitmap, Rectangle

from System.Drawing import Graphics, Image

from Spotfire.Dxp.Framework.ApplicationModel import ApplicationThread

from System.IO import Path

from System.Windows.Forms import FolderBrowserDialog,MessageBox

 

#Choose Folder to save visualization

filename=""

folder=FolderBrowserDialog()

result=folder.ShowDialog()

if result==result.OK:

filename=folder.SelectedPath

else:

MessageBox.Show("Please select a folder and try again")

 

app = Application.GetService(ApplicationThread)

image = Bitmap(800, 600)

def f(visual=visual, document=Document, app=app, image=image, Graphics=Graphics, Rectangle=Rectangle):

try:

vis = visual

gfx = Graphics.FromImage(image)

rect = Rectangle(0,0,image.Width,image.Height)

vis.Render(gfx, Rectangle(0,0,image.Width,image.Height))

imageFilename = filename + "image.png"

except:

return

# DO SOMETHING WITH THE IMAGE HERE

image.Save(imageFilename)

app.InvokeAsynchronously(f)

Hi,

I do run the script from the script editor, then you will get the errors created by the script.

 

I pasted your script in adefault report of Analyst, and then executed it from the Script editor, and just corrected the few errors I got.

Below is the script I got working, saving to my desktop, and adding the script parameter 'visual' pointing to one of the visualizations.
