Python Forum

im looking for DDS libraries that can create {bc3 rgba 8 bpp DXT5: interpolated alpha" + genarated mipmaps}

PIL can create .dds but limited output
PYDDS can not save to .DDS

thx for any help

This works as i want but i can not use WAND as i need a standalone .exe when done, so i can share the app.

import os
from wand.image import Image

def convert_png_to_dds():
    # Get the current working directory
    input_dir = os.getcwd()
    output_dir = os.path.join(input_dir, "dds_output")  # Output in a subfolder

    # Create output directory if it doesn't exist
    os.makedirs(output_dir, exist_ok=True)

    # Iterate over all files in the current directory
    for filename in os.listdir(input_dir):
        if filename.endswith('.png'):
            input_path = os.path.join(input_dir, filename)
            output_filename = f"{os.path.splitext(filename)[0]}.dds"
            output_path = os.path.join(output_dir, output_filename)

            # Convert PNG to DDS
            with Image(filename=input_path) as img:
                img.compression = 'dxt5'  # Set compression to DXT5
                img.mipmaps = True          # Generate mipmaps
                img.save(filename=output_path)
                print(f"Converted: {input_path} to {output_path}")

if __name__ == "__main__":
    convert_png_to_dds()

Just as an FYI encase any other modders find this as next to no info is available for this.

Solved it using texconv.exe from
https://github.com/microsoft/DirectXTex/wiki/Texconv

.dds are to be created for World of Tanks.
The below script will convert all .png in the script folder to.dds in /dds_output/

import os
import subprocess

# Set the output directory
output_dir = 'dds_output'

# Create the output directory if it doesn't exist
if not os.path.exists(output_dir):
    os.makedirs(output_dir)

# Iterate over all PNG files in the current directory
for filename in os.listdir('.'):
    if filename.endswith('.png'):
        # Prepare the command to convert PNG to BC3 DXT5 with mipmaps
        input_file = filename
        output_file = os.path.join(output_dir, f'{os.path.splitext(filename)[0]}.dds')

        # Command to run Texconv
        command = [
            'Texconv.exe',  # Change this to the path if Texconv.exe is not in the same folder
            '-f', 'dxt5',  # Set compression format: DXT5 (BC3, for RGBA images)
            '-m', '9',  # Generate 9 levels of mipmaps
            '-o', output_dir,  # Output directory
            '--separate-alpha', #separate alpha
            input_file  # Input file
        ]

        # Run the command
        print(f'Converting {input_file} to {output_file}...')
        subprocess.run(command)

print('Conversion completed!')
