Huite, nice that you added this issue. Based on our discussion on the NewOrleans project where I needed the labels for my cross section. For that reason I create a new issue to upgrade imod.visualize.cross_section

My quick fix for now:

def read_imod_legend(path):    
   ...
   ...
   labels = list(legend["domain"])[::-1][1:]
return colors, levels, labels

Hi @JoerivanEngelen , this is an easy fix and logical addition. And it works. Can you add it to the code?

the update of the code is slightly more than suggested in an earlier post.
It should be

# From def read_imod_legend(path):
def _read(delim_whitespace):
    return pd.read_csv(
        path,
        header=1,
        delim_whitespace=delim_whitespace,
        index_col=False,
        usecols=[0, 1, 2, 3, 4, 5],
        names=["upper", "lower", "red", "green", "blue", "domain"],
    )

# Try both comma and whitespace separated
try:
    legend = _read(delim_whitespace=False)
except ValueError:
    legend = _read(delim_whitespace=True)

# The colors in iMOD are formatted in RGB. Format to hexadecimal.
red = legend["red"]
blue = legend["blue"]
green = legend["green"]
colors = [f"#{r:02x}{g:02x}{b:02x}" for r, g, b in zip(red, green, blue)][::-1]
levels = list(legend["lower"])[::-1][1:]
labels= list(legend["domain"])[::-1][1:]

return colors, levels, labels

Hi @FransRoelofsen,

Thanks for reminding me and adding some code to showcase what you want, two questions:

• Is this a requirement for the 1.0 release in your opinion? If so I'll add it to the milestone
• Could you share some example files here which should work?

1. Please make it available in 1.0 while it is a simple improvement but most of all: it could be important for iMOD5 users to try iMOD Python.
2. FYI: LEG files can not be uploaded so I changed it into LEG.TXT.
