This model is a workflow that allows 2 people to hug when their pictures are given. It was created by fixing the non-working parts of the workflow published by T8star-Aix. If I am asked to remove it, I will remove it.

The changes made are shown in the video replacing the image cropper nodes and also the errors received are fixed in the code as follows:

ValueError: Invalid hex color format

Solution to this error :

Check where the expand_and_mask function is called:

Define fill_color variable on line 704 of TTP_toolsets.py.

Verify if it is an invalid HEX code:

HEX color codes should usually have the format #RRGGBB or #RRGGBBAA (example: #FF5733 or #FF5733FF).

If fill_color is in a wrong format (#FF573, 123456, red, etc.), this error will be received.

Validate HEX Format in hex_to_rgba Function

Update the hex_to_rgba function on line 559 of TTP_toolsets.py:

For example, you could add a regex check like the one below:

Change the code to:

import re

def hex_to_rgba(self, hex_color):

# If '#' is present, clear from the beginning

hex_color = hex_color.lstrip('#')

# Check if HEX format is valid

if not re.match(r'^[A-Fa-f0-9]{6}$|^[A-Fa-f0-9]{8}$', hex_color):

raise ValueError(f “Invalid hex color format: {hex_color}. Expected format is #RRRGGBB or #RRRGGBBAA.")

# If 6 characters, return with default alpha value 255 (full opacity)

if len(hex_color) == 6:

r = int(hex_color[0:2], 16)

g = int(hex_color[2:4], 16)

b = int(hex_color[4:6], 16)

return (r, g, b, 255)

# If 8 characters, the last two characters indicate the alpha (transparency) value

elif len(hex_color) == 8:

r = int(hex_color[0:2], 16)

g = int(hex_color[2:4], 16)

b = int(hex_color[4:6], 16)

a = int(hex_color[6:8], 16)

return (r, g, b, a)

else:

raise ValueError(f “Invalid hex color format: {hex_color}”)
