Input and method

The input is a project-created synthetic product image. One edit request asked to keep the cup shape, color, blue lettering and composition, and change only the yellow background to light green. The exact Chinese prompt was sent without an LLM rewrite.

These are real API samples submitted to APIMart using the project request builders. Prompts were sent directly with smart rewriting off. References are public, project-owned fictional assets; outputs were not retouched. They demonstrate sample results, not an end-to-end customer checkout test.

What the result shows

The saved output has a light green background and keeps a white cup with readable blue SYNC lettering. Compare the original files below to judge the silhouette, text and framing.

Limits and checks

This is a generated edit, not a pixel-locked cutout. Small shadow, edge or framing changes can occur. One short word on one synthetic cup is not evidence that every logo, label or product dimension will be preserved.
