Send the `run_id`, the `target_language_id` of the translation you want to change, the `region_id` of the text region, and a `prompt` describing what you want. You can find region IDs in [Get Image Translation Project](https://docs.camb.ai/api-reference/endpoint/get-image-translation-project.md). ## Writing a Good Prompt The `prompt` is a short, plain-language instruction that applies to the one region you selected. Be specific about what should change, whether that is the wording or how the text looks: its color, font, size, or shadow. A single sentence is usually enough. Examples: * `Change the text color to white` * `Use a bolder, larger font` * `Add a soft drop shadow behind the text` * `Make the text color more vibrant` * `Shorten the translation so it fits the speech balloon` Because each prompt only affects one region, send a separate request for each region you want to adjust. ## Applying the Result The response contains a `task_id` and a `user_message` (the prompt as stored on the run). To see the change in your download: 1. Poll [`/image-translation/{task_id}`](get-end-to-end-image-translation-status) until the status is `SUCCESS` 2. Call [Export Image Translation](https://docs.camb.ai/api-reference/endpoint/export-image-translation.md). A fine-tune doesn't update your download on its own, so this step is required for the change to appear 3. Fetch the updated pages from [`/image-translation/result/{run_id}`](get-image-translation-result) ## Request Example ```python [expandable] theme={null} import os import requests headers = { "x-api-key": os.environ["CAMB_API_KEY"], "Content-Type": "application/json", } response = requests.post( "https://client.camb.ai/apis/image-translation/fine-tune", headers=headers, json={ "run_id": 12345, "target_language_id": 54, "region_id": 1, "prompt": "Use a bolder font and make the text color more vibrant", }, ) response.raise_for_status() print(response.json()["task_id"]) ``` ## OpenAPI ````yaml post /image-translation/fine-tune openapi: 3.1.0 info: title: FastAPI version: 0.1.0 servers: - url: https://client.camb.ai/apis security: [] paths: /image-translation/fine-tune: post: tags: - Apis - Image Translation summary: Fine-Tune Image Translation description: >- Adjust a single text region with a prompt.
