How to set label renderer in IronPython for image from column

[Kevin Brogle]

I am writing IronPython scripts to allow the changing of marker labels through a property control. I have found the proper syntax to select DefaultRenderer, LinkRenderer, or ImageFromURLRenderer for SetLabelRenderer(ValueRendererTypeIdentifiers.[renderer]). However, How do I set the renderer if the image comes from a column, not a URL? If I use ImageFromURLRenderer it expects a URL and there isn't one. If I use DefaultRenderer it just says Binary. Manually, I just select Image from the dropdown.

TIA

I found which value renderer to use by printing out the value of the current value renderer when it was manually set to Image.

Turns out to be a BitmapRenderer. So this script should work (vis is an input parameter for your visualization):

from Spotfire.Dxp.Application.Visuals import *

from Spotfire.Dxp.Application.Visuals.ValueRenderers import *

vis = vis .As[Visualization]()

myRenderer = vis .SetLabelRenderer( ValueRendererTypeIdentifiers.BitmapRenderer)

Thank you Gaia. That worked.

BTW, how do I print out values?

[Gaia Paolini]

I meant adding a print statement

print(vis.LabelRenderer.GetType() )

without trying to change the renderer, then executing the script with Run Script while you are editing it.

That returned Spotfire.Dxp.Application.Visuals.ValueRenderers.BitmapValueRendererSettings.
