This is a Python script that converts and pads the images in a specified directory to a common aspect ratio and compresses them to jpg format. It uses the Pillow library for image manipulation and the Tkinter library for creating a graphical user interface.

• Python 3.10
• Pillow 10.0

• Run the script using python image_converter_and_padder.py
• A window will appear with some options to configure the conversion process.
• Select the source directory where the images are located by clicking on the "Select source" button.
• Select the destination directory where the converted images will be saved by clicking on the "Select destination" button.
• Choose one of the common aspect ratios from the drop-down menu labeled "Aspect ratio".
• Enter the jpg quality in the range of 0 to 100 in the entry box labeled "Quality".
• Enter the padding color in hexadecimal format (e.g. "#FFFFFF" for white) in the entry box labeled "Color".
• Click on the "Convert" button to start the conversion process.
• A text box will show a message when the conversion process is completed.
• The script will convert and pad all the images in the source directory that have one of these extensions: ".jpg", ".tga", ".png", ".jpeg".
• The script will copy any ".gif" files without modifying them.
• The script will save the converted images as ".jpg" files in the destination directory with the same file name as the original image.
• The script will use multithreading to speed up the conversion process. The maximum number of threads is set to 10 by default, but you can change it by modifying the max_threads variable in the code.
