Shared Claude Code translation pipeline (scripts/i18n, no API key) plus Astro/VitePress/Scalar i18n wiring. Landing and API reference translated into all 20 languages; docs i18n wiring + English source anchors. The translated docs markdown (apps/docs/<locale>/**, 3,620 files) follows in a companion PR because it exceeds GitHub's per-PR CI file limit.

# SVG to Raster {#svg-to-raster}
|
|
|
|
Convert SVG files to raster image formats (PNG, JPEG, WebP, AVIF, TIFF, GIF, HEIF, or JXL) at custom resolution and DPI. Also supports batch conversion of multiple SVGs.
|
|
|
|
## API Endpoint {#api-endpoint}
|
|
|
|
`POST /api/v1/tools/image/svg-to-raster`
|
|
|
|
## Parameters {#parameters}
|
|
|
|
| Parameter | Type | Required | Default | Description |
|
|
|-----------|------|----------|---------|-------------|
|
|
| width | integer | No | - | Target width in pixels (1 to 65536). Maintains aspect ratio if only one dimension set. |
|
|
| height | integer | No | - | Target height in pixels (1 to 65536). Maintains aspect ratio if only one dimension set. |
|
|
| dpi | integer | No | 300 | Render DPI, controls the base rasterization density (36 to 2400) |
|
|
| quality | number | No | 90 | Output quality for lossy formats (1 to 100) |
|
|
| backgroundColor | string | No | `"#00000000"` | Background color as hex (6 or 8 characters, 8-char includes alpha) |
|
|
| outputFormat | string | No | `"png"` | Output format: `png`, `jpg`, `webp`, `avif`, `tiff`, `gif`, `heif`, `jxl` |
|
|
|
|
## Example Request {#example-request}
|
|
|
|
```bash
|
|
curl -X POST http://localhost:1349/api/v1/tools/image/svg-to-raster \
|
|
-F "file=@logo.svg" \
|
|
-F 'settings={"width":1024,"dpi":300,"outputFormat":"png","backgroundColor":"#FFFFFF"}'
|
|
```
|
|
|
|
## Example Response {#example-response}
|
|
|
|
```json
|
|
{
|
|
"jobId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
|
|
"downloadUrl": "/api/v1/download/a1b2c3d4-e5f6-7890-abcd-ef1234567890/logo.png",
|
|
"previewUrl": "/api/v1/download/a1b2c3d4-e5f6-7890-abcd-ef1234567890/preview.webp",
|
|
"originalSize": 12345,
|
|
"processedSize": 67890
|
|
}
|
|
```
|
|
|
|
## Batch Endpoint {#batch-endpoint}
|
|
|
|
`POST /api/v1/tools/image/svg-to-raster/batch`
|
|
|
|
Convert multiple SVG files in one request. Returns a ZIP archive.
|
|
|
|
### Additional Batch Parameters {#additional-batch-parameters}
|
|
|
|
| Parameter | Type | Required | Default | Description |
|
|
|-----------|------|----------|---------|-------------|
|
|
| clientJobId | string | No | - | Optional client-provided job ID for progress tracking (max 128 chars) |
|
|
|
|
### Batch Example Request {#batch-example-request}
|
|
|
|
```bash
|
|
curl -X POST http://localhost:1349/api/v1/tools/image/svg-to-raster/batch \
|
|
-F "file=@icon1.svg" \
|
|
-F "file=@icon2.svg" \
|
|
-F "file=@icon3.svg" \
|
|
-F 'settings={"width":512,"outputFormat":"png","dpi":150}'
|
|
```
|
|
|
|
### Batch Response {#batch-response}
|
|
|
|
The batch endpoint streams a ZIP file directly with headers:
|
|
- `Content-Type: application/zip`
|
|
- `X-Job-Id: <jobId>`
|
|
- `X-File-Results: <url-encoded JSON mapping of index to filename>`
|
|
|
|
## Notes {#notes}
|
|
|
|
- Only accepts SVG and SVGZ files (validates content, not just extension). SVGZ is automatically decompressed.
|
|
- SVG content is sanitized before rendering to prevent XSS and external resource loading.
|
|
- The `dpi` setting controls the density at which the SVG is rasterized. Higher DPI produces larger pixel dimensions from the same SVG viewport.
|
|
- When both `width` and `height` are provided, the image is resized using `fit: inside` (maintains aspect ratio within the bounds).
|
|
- A `previewUrl` is included in the response for formats that browsers cannot display natively (TIFF, HEIF). The preview is a 1200px WebP thumbnail.
|
|
- The default background `#00000000` is fully transparent. Set to `#FFFFFF` for a white background (useful with JPEG output which does not support transparency).
|
|
- Batch processing respects the `MAX_BATCH_SIZE` server configuration and uses concurrent workers for performance.
|
|
- Progress for batch operations can be tracked via SSE at `/api/v1/jobs/:jobId/progress`.
