[Python] ezdxf python - How can I set the plot transparency configuration in the plotsettings...

I have a code that plots a layout created with ezdxf, but I have trouble setting my plot transparency option, because I have a external reference with an image that I want to be 40% transparent.

This is the code I use for plotting the whole dxf file, but I dont know how to set the transparency option to True in the plot options, I cant find the docs for this references.

Also it would be very nice if when I create my layout in the ezdxf, I could set all this plotting options for each layout.

doc = ezdxf.readfile(dxf_path)
layout = doc.layouts.new(name='layout_name')
layout.applyPlotOptions(papersize="ISO_full_bleed_A1_(841.00_x_594.00_MM)", plotsytle table='style.ctb', plottransparency=0.6, etc)


I would very much appreciatte any help on this.

Chelo.

# Initialize AutoCAD
acad = win32com.client.Dispatch("AutoCAD.Application")
acad.Visible = False # Set to False if you don't want to show AutoCAD

# Open the DWG file
doc = acad.Documents.Open(dwg_path)

# Loop through all layouts
for i in range(doc.Layouts.Count):
print(i)
time.sleep(5)
layout = doc.Layouts.Item(i + 1) # Indexing starts from 1 in COM

# Set the layout as active
doc.ActiveLayout = layout

# Configure the plot settings
doc.ActiveLayout.ConfigName = "DWG To PDF.pc3" #se puede cambiar a cualquier pc3 configurado
doc.ActiveLayout.StyleSheet = ctb_file_path
# doc.ActiveLayout.CanonicalMediaName = "ISO_expand_A4_(210.00_x_297.00_MM)" #debe coincidir exctamente el nombre
doc.ActiveLayout.CanonicalMediaName = "ISO_full_bleed_A1_(841.00_x_594.00_MM)" #debe coincidir exctamente el nombre


# Set the output file path
output_file_path = f"{output_folder}/{layout.Name}.pdf"

# Plot the layout
doc.Plot.PlotToFile(output_file_path)
time.sleep(5)

# Close the document without saving changes
doc.Close(SaveChanges=True)

# Quit AutoCAD
acad.Quit()
