What to build

Inline horizontal progress bar overlaid on a region. Value in [0, 1]. Useful for confidence indicators, quality scores, and progress strips on tile-sheet comparisons.

imgviz.draw.progress_bar(image, yx1, yx2, value, fill=(0, 200, 0), background=(0, 0, 0), border=None)

Acceptance criteria

• value=0 leaves bar empty (background only)
• value=1 fills bar entirely
• Value clamped to [0, 1]
• Optional border via border
• Docstring with example
• Example snippet in examples/
