Building the Executable (Windows)

1. Install pyinstaller: You can build an executable file using PyInstaller. First, make sure you have PyInstaller installed:

pip install pyinstaller

2. Build the Executable: Next, use the following command to build the .exe file:

3. Locate the Executable: After running the command, you'll find the a standalone executable named AutoWatermark.exe in the dist folder.

Building for macOS

If you are using a macOS system, you can build the application into a standalone .app bundle using PyInstaller. The process is similar to building the Windows executable, but the command has a different format for the --add-data option.

1. Install PyInstaller: If you haven't installed PyInstaller, install it using:

pip install pyinstaller

2. Build the Application: Use the following command to build the .app bundle:

pyinstaller -w -F --add-data="AutoWatermark.ui:./" AutoWatermark.py

Note the change in the --add-data option, using a colon (:) instead of a semicolon (;).

3. Locate the Application: After running the command, you'll find the AutoWatermark.app bundle in the dist folder.

Additional Notes for macOS
