Migration Guide

From 0.9.x to 1.0.0

Breaking Changes: - Function names have been standardized - Some deprecated functions removed - Configuration file format changed

Migration Steps:

  1. Update function calls:

    # Old (0.9.x)
image = load_image("photo.jpg")
tinted = tint_image(image, "#FF0000")

# New (1.0.0)
image = gui_image_studio.get_image("photo.jpg")
tinted = gui_image_studio.apply_tint(image, "#FF0000")

  2. Update CLI commands:

    # Old (0.9.x)
python image_studio.py
python create_samples.py

# New (1.0.0)
gui-image-studio-designer
gui-image-studio-create-samples

  3. Update imports:

    # Old (0.9.x)
from image_loader import get_image

# New (1.0.0)
import gui_image_studio
# or
from gui_image_studio import get_image

Deprecated Functions (Removed in 1.0.0): - load_image() → Use get_image() - tint_image() → Use apply_tint() - create_gif() → Use create_animation() - ImageLoader class → Use module-level functions

From 0.8.x to 0.9.x

Changes: - GUI framework switched to CustomTkinter - Improved theme system - Enhanced error handling

Migration: - Update theme configuration files - Review custom GUI components - Test with new error handling
