String Resolution Gemini 3.1 Flash Image - Gemini 3.1 Flash Image Resolution Selector
Node Purpose: String Resolution Gemini 3.1 Flash Image outputs the nearest Gemini 3.1 Flash Image resolution tier label (0.5k / 1k / 2k / 4k) 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 Gemini 3.1 Flash Image.

Features
- Gemini 3.1 Flash Image tiers:
0.5k / 1k / 2k / 4k, 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 Gemini 3.1 Flash Image 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 the official 1:1 size of each Gemini 3.1 Flash Image tier (1k is 1024x1024, others scale by 0.5/1/2/4) 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.
