String Resolution Qwen Image 3.0 Pro - Qwen Image 3.0 Pro Resolution Selector
Node Purpose: String Resolution Qwen Image 3.0 Pro outputs the nearest Qwen Image 3.0 Pro resolution tier label (1k / 2k) for each input image based on image area. If no image is connected, it passes through the manually selected label. It is designed to pair with Qwen Image 3.0 Pro.

Features
- Qwen Image 3.0 Pro tiers:
1k / 2k, using each tier's official 1:1 size area as the target.
- Area-based matching: compares image area against the tier target areas and picks the nearest in log space.
- Manual fallback: returns the selected label directly when
image is empty.
- Batch support: outputs one resolution label per image in the batch.
Typical Usage
- Convert image size into a resolution label before Qwen Image 3.0 Pro nodes that expect a resolution string, and connect it to the API node's
resolution input.
- Keep manual control by leaving
image unconnected and selecting a fixed label.
Notes & Tips
- Matching is based on total pixel area, not exact width/height ratio.
- The target areas match
QwenImage30Pro.MAX_PIXELS_BY_RESOLUTION in 1hewOffice (1k=1024², 2k=2048²) item by item; that source belongs to 1hewOffice and its code is not in this repository.
- This node only outputs the string label and does not resize the image.
