Hi all,
i need some scripting advice here. I have a Python script that can apply labels one by one to a scene and render them individually. Now comes the hard part, because some labels will have different sizes or aspect ratios. Is there any way in scripting to read/adjust the label size applied to a material?
Thank you in advance!
Hello,
Certainly! In Python, you can adjust the size of a label based on its aspect ratio by using the dimensions of the label image and scaling it accordingly before applying it to a material. Here’s a general approach you might consider:
Read the label image to get its size.
Calculate the desired aspect ratio for the label on the material.
Scale the label image to maintain the aspect ratio when applied to the material.
Here’s a sample script that demonstrates how to resize an image while maintaining its aspect ratio using the Python Imaging Library (PIL), which is now known as Pillow:
from PIL import Image
def resize_image(input_image_path, output_image_path, desired_width):
with Image.open(input_image_path Official Site) as image:
original_width, original_height = image.size
aspect_ratio = original_height / original_width
new_height = int(desired_width * aspect_ratio)
resized_image = image.resize((desired_width, new_height), Image.LANCZOS)
resized_image.save(output_image_path)
This function takes an input image path, an output image path, and a desired width. It calculates the new height based on the original aspect ratio and resizes the image accordingly. You can integrate this function into your script to resize the labels before applying them to the scene.
pip install Pillow
Adjust the script to fit your specific use case, such as applying the resized label to a material in your scene. If you’re working with 3D models and materials, you might need to look into the specific 3D rendering library or engine you’re using for additional functions related to material manipulation.
I hope the information may helps you.
