Webtoon Cropper

The Webtoon Cropper is designed specifically for vertical scroll webtoon images. It helps you split long webtoon strips into individual panel segments.

When to Use

• Your source material is a long vertical webtoon strip
• You need to split a continuous scroll into discrete panels
• You want manual control over where panel breaks occur
• The automatic detection in Step 1 needs supplemental cropping

How to Use

1. Open the Tool Suite panel → select Webtoon Cropper
2. Click Load Images to import your webtoon pages
3. Draw horizontal bounding boxes to define panel segments along the vertical strip
4. Adjust boundaries as needed using drag handles
5. Use Undo/Redo for corrections
6. Click Export to save segments as individual images

Features

• Optimized for vertical format — handles the tall aspect ratios typical of webtoons
• Bounding box editor — create and edit crop regions visually
• Undo/Redo — full command history
• Batch export — save all segments at once
• Auto-numbered output — exported images are numbered in top-to-bottom order

Manga Cropper vs. Webtoon Cropper

| Feature | Manga Cropper | Webtoon Cropper | |---------|---------------|-----------------| | Best for | Page-based manga | Vertical scroll webtoons | | Layout | 2D panel grids | Top-to-bottom strips | | Reading direction | Right-to-left or left-to-right | Top-to-bottom |

Tips

• For best results, crop at natural scene breaks (between panels, not through them)
• The exported segments can be loaded directly into the core pipeline
• If your webtoon pages are already split into individual panels, you can skip this tool and go straight to Step 1
