# Image Upscaling {#image-upscaling}
|
||
|
|
|
||
|
|
Peningkatan super-resolusi AI menggunakan Real-ESRGAN. Memperbesar gambar 2x-4x sambil mempertahankan detail.
|
||
|
|
|
||
|
|
## API Endpoint {#api-endpoint}
|
||
|
|
|
||
|
|
`POST /api/v1/tools/image/upscale`
|
||
|
|
|
||
|
|
**Processing:** Asinkron (mengembalikan 202, poll `/api/v1/jobs/{jobId}/progress` untuk status melalui SSE)
|
||
|
|
|
||
|
|
**Model bundle:** `upscale-enhance` (5-6 GB)
|
||
|
|
|
||
|
|

## Notes {#notes}
|
||
|
|
|
||
|
|
- Memerlukan model bundle `upscale-enhance` untuk diinstal (5-6 GB).
|
||
|
|
- Menggunakan Real-ESRGAN jika tersedia; kembali ke interpolasi Lanczos jika model AI tidak tersedia.
|
||
|
|
- Opsi `faceEnhance` menerapkan pemulihan wajah GFPGAN selama pembesaran untuk kualitas wajah yang lebih baik.
|
||
|
|
- Untuk format keluaran yang tidak dapat dipratinjau di browser (HEIC, JXL, TIFF), pratinjau WebP dihasilkan bersama keluaran utama.
|
||
|
|
- Mendukung format masukan HEIC/HEIF, RAW, TGA, PSD, EXR, dan HDR melalui pendekodean otomatis.
