This Python script provides a simple GUI for resizing the canvas of PNG files. It allows users to choose between processing a single file or multiple files in a folder. The script uses the PIL (Pillow) library for image processing.
-
Canvas Size Options:
- Auto: Resizes the canvas to be square, using the maximum of the original width and height.
- Rescale: Prompts the user for a scale factor to adjust both the canvas and image elements.
- Custom: Prompts the user for a desire resolution to adjust both the canvas and image elements.
-
User Interaction:
- The script prompts users to select the file type ('single' or 'multiple') and canvas size option.
- For the 'rescale' option, users enter a scale factor for adjusting the canvas and image elements.
-
File Handling:
- The script creates an output folder for the resized images if it doesn't exist.
- If the source and output folders are the same, the script overwrites the source files with the processed ones.
- Python 3.x
- Pillow library (install using
pip install pillow)
- Run the script by executing the command:
python main.py - Select the file type ('single' or 'multiple').
- Choose the canvas size option ('auto','rescale', or 'custom').
- If 'rescale' is selected, enter the scale factor when prompted.
- If 'custom' is selected, enter the desire resolution when prompted.
- Select the source file or folder.
- Choose the output folder for saving the resized images.
- The script will process the images based on the selected options.
-
Ensure that the Pillow library is installed before running the script.
-
If the source and output folders are the same, the script will automatically overwrite the source files with the processed ones.
-
In case of any errors during the resize process, the script will print an error message with details.
