生成一段使用gdal批量将tif格式转换成png格式的带有注释的python代码

Sure, here's a Python code snippet that uses the GDAL library to batch convert TIFF files to PNG format:

import os
from osgeo import gdal

# Set input and output directories
input_dir = '/path/to/tif/files'
output_dir = '/path/to/png/files'

# Loop through each file in input directory
for filename in os.listdir(input_dir):
    if filename.endswith('.tif'):
        # Open TIFF file
        tif_file = gdal.Open(os.path.join(input_dir, filename))

        # Set output file name
        png_file = os.path.splitext(filename)[0] + '.png'
        output_path = os.path.join(output_dir, png_file)

        # Convert TIFF to PNG
        gdal.Translate(output_path, tif_file, format='PNG')

        # Add comment to output file
        with open(output_path, 'a') as f:
            f.write('# Converted from TIFF using GDAL')

print('Conversion complete')

Hope this helps! Let me know if you have any other questions.
