關於 Bria Expand Image
將 `image_url` 中的影像延伸至由 `canvas_size` 定義的更大畫布,面積應低於 5000x5000 像素。也可使用 `aspect_ratio`(1:1、2:3、3:2、3:4、4:3、4:5、5:4、9:16、16:9),其優先級高於手動尺寸與位置。可透過 `original_image_size` 和 `original_image_location` 放置原圖,並使用英文 `prompt` 指引填補內容。
參數
請傳送標準名稱或原生名稱其中之一,不要同時傳送兩者。 標準名稱
名稱類型
預設值允許值
說明
image_url必填
image
類型url · image
輸入圖像 URL。
canvas_size必填
類型integer[]
擴展圖像的尺寸,面積必須嚴格小於 5000 × 5000 像素。
aspect_ratio選填
類型enum
1:12:33:23:44:34:55:49:1616:9
提供時會覆寫 `original_image_size` 和 `original_image_location` 的最終圖像長寬比。
original_image_size選填
類型integer[]
來源圖像在完整畫布中的目標尺寸;提供 aspect_ratio 時會忽略。為獲得最佳結果,輸入中的前景或主要主體應占畫布面積超過 15%。
original_image_location選填
類型integer[]
將原始圖像定位於完整畫布的左上角座標;提供 `aspect_ratio` 時一律忽略。若位置超出畫布,結果會進行裁切,此情況允許發生。
prompt選填
類型string
預設值
可選的引導圖像擴展文字。目前提示詞僅支援 English,且不得包含特殊字元。
seed選填
類型integer | null
0 – 2,147,483,647
用於重現擴展結果的可選種子:提供先前結果回傳的種子即可重現。省略時,若不需要可重現性,系統會隨機生成。
negative_prompt選填
類型string
預設值
用於圖像生成的負面文字提示詞。
必填
標準名稱,也可使用
檔案參數接受公開的 https:// URL、最大 10 MB 的 data: URI,或上傳檔案的 file_url。 檔案
