Release Note

Dependency Updates

Replaced docsaidkit utilities with capybara:
- For image resizing and file-handling functionalities.
- Introduced at the start to emphasize its importance in enhancing functionality and performance.

Renamed and Refactored Modules:
- imgaug.py was renamed to custom_aug.py to better reflect its role in handling custom augmentation functionalities.
- Utilities from base.py and utils.py were restructured into more specialized modules for improved code clarity and maintainability:
  - font_utils.py: Dedicated to font management, including loading, validating fonts, and introducing new functions for Unicode character validation and filtering.
  - text_image_renderer.py: Handles text-to-image rendering with extensive customization options, including multi-line text support and text stroke features.
- Machine Readable Zone (MRZ) related functions from mrz.py and text2image.py were consolidated into mrz_generator.py for streamlined MRZ generation.
Introduced New Modules:
- font_utils.py:
  - Implements font-related operations like loading, filtering, and validating characters against Unicode ranges.
  - Added multiple new functions to enhance font validation and improve robustness in character checks.
- text_image_renderer.py:
  - Enables rendering of text into images with configurable direction, alignment, stroke, and spacing.
  - Introduced multi-line text rendering and enhanced text stroke options.
- mrz_generator.py:
  - Focused exclusively on generating MRZ images with validation for text formatting and spacing.

WordCanvas and RandomWordCanvas:
- Split WordCanvas into two dedicated classes:
  - WordCanvas focuses on static, predictable text rendering.
  - RandomWordCanvas specializes in dynamic, randomized text and style generation.
- Expanded randomization options for font, color, direction, and spacing.
- Refined logic for image dimension adjustments and text alignment.
MRZGenerator:
- Improved flexibility for generating MRZ text, supporting customizable lines, spacing, and randomization.
- Enhanced character placement accuracy within MRZ images.
text2image:
- Added features to control text stroke width and fill color.
- Introduced support for multi-line text rendering.
- Improved text alignment and spacing calculations for better visual rendering.
- Returns metadata such as font path, actual font size, and text direction for enhanced traceability.

Comprehensive Test Coverage:
- Introduced new test files:
  - test_custom_aug.py:
    - Validates Shear augmentation under various probabilities and parameter combinations.
  - test_font_utils.py:
    - Ensures font-loading mechanisms and character filtering work as expected.
    - Tests new font validation functions thoroughly.
  - test_mrz_generator.py:
    - Tests MRZ generation for types TD1, TD2, and TD3 with text validation.
  - test_text_image_renderer.py:
    - Checks rendering accuracy, including alignment, direction, and text clamping.
    - Verifies new multi-line text and text stroke rendering.
  - test_word_canvas.py:
    - Validates WordCanvas and RandomWordCanvas functionalities, covering randomization and image alignment.
Advanced Testing Strategies:
- Utilized pytest.mark.parametrize for efficient multi-case testing.
- Simulated edge cases, including invalid font paths and incorrect text directions.
- Integrated testing for combined functionalities (e.g., Shear and ExampleAug).
- Enhanced error handling to strengthen validation for unsupported characters and corrupted fonts.

Removed the following obsolete or redundant files:
- Test files: test_generator.py, test_imgaug.py, test_utils.py.
- Modules: mrz.py, base.py, utils.py, text2image.py.
