Hello, I am using ArcGIS Pro 3.2 on my desktop, and I am using a for loop within Arcpy to export layouts of .tiff files to png. I'm applying a symbology layer using
arcpy.management.ApplySymbologyFromLayer
and then later setting each layer's transparency using, e.g.,
layer.transparency = 50
This works great, except that the symbology (I use ~15 classes) in the legend does not show the transparency. I know I could click on each class, go to Color Properties, and change the transparency there. But is there any way to do it for all classes at once instead of one at a time (which is tedious)? Doing this within Arcpy would also be an option (again, avoiding tedium).
