Use AR Instance Directly

<script lang="ts">
  import { getContext } from 'svelte';
  import type { ARInstance, TransformOptions } from '@autorender/sdk-core';
  
  const AR: ARInstance = getContext('autorender');
  
  const imageUrl = $derived(AR.url('image.jpg', { w: 300, h: 300, fit: 'cover' }));
  const transformString = $derived(AR.transformString({ w: 300, h: 300 }));
  const dpr = $derived(AR.getDPR());
  const connectionQuality = $derived(AR.getConnectionQuality());
  
  const attrs = $derived(AR.responsiveImageAttributes({
    src: 'hero.jpg',
    width: 1200,
    sizes: '(min-width: 800px) 50vw, 100vw',
    transform: { fit: 'cover' }
  }));
</script>

<img 
  src={imageUrl} 
  srcset={attrs.srcSet} 
  sizes={attrs.sizes} 
  width={attrs.width} 
  alt="Image" 
/>

API Reference

Upload SDK

autorenderUploader(node, options)

Svelte action that attaches the uploader to an element.

Parameters:

• node: HTMLElement - Target element
• options: AutorenderUploaderParameters - Uploader options

ViewTag SDK

<AutoRenderProvider />

Svelte component that provides AR instance via context.

Props:

• baseUrl?: string - Base URL (default: 'https://assets.autorender.io')
• workspace: string - Your workspace ID
• defaults?: { f?: string, q?: string | number } - Default transformations
• deviceBreakpoints?: number[] - Device breakpoints
• imageBreakpoints?: number[] - Image breakpoints
• enableDPR?: boolean - Enable device pixel ratio (default: true)
• enableResponsive?: boolean - Enable responsive images (default: true)
• connectionQuality?: 'auto' | '2g' | '3g' | '4g' | 'wifi' - Connection quality override

<ARImage />

Svelte component that wraps <img> with AutoRender transformations.

Props:

• src: string - Image source path (required)
• width?: number - Image width in pixels
• height?: number - Image height in pixels
• transform?: TransformOptions - Transformation options (see TransformOptions Reference below)
• responsive?: boolean - Enable responsive images (default: true)
• lazy?: boolean - Enable lazy loading (default: true)
• sizes?: string - Sizes attribute for responsive images
• All standard <img> HTML attributes are forwarded (e.g., alt, class, style, on:click, etc.)

Context: 'autorender'

Access the AR instance via Svelte's getContext('autorender').

Type: ARInstance with methods:

• url(src: string, transform?: TransformOptions): string - Generate image URL
• transformString(transform: TransformOptions): string - Get transformation string only
• responsiveImageAttributes(options: ResponsiveOptions): ResponsiveAttributes - Generate responsive image attributes
• getDPR(): number - Get device pixel ratio
• getConnectionQuality(): '2g' | '3g' | '4g' | 'wifi' | 'unknown' - Get connection quality

TransformOptions Reference

All transformation parameters available in the transform prop. See React SDK README for complete reference.

Size & Crop

• w?: number - Width in pixels
• h?: number - Height in pixels
• fit?: 'crop' | 'fill' | 'fit' | 'scale' - Crop mode
• ar?: string - Aspect ratio (e.g., "16:9")
• p?: string - Position/gravity
• ps?: 'center' | 'entropy' | 'attention' - Position strategy

Preset (named transformation)

• preset?: string - Optional named preset, which becomes a leading t_<preset> segment in the URL.

  Example:

  <ARImage
    src="avatar.png"
    width={100}
    height={100}
    alt="Unavailable avatar"
    transform={{ preset: 'unavailable', w: 100, h: 100 }}
  />
  <!-- Results in: /workspace/t_unavailable,w_100,h_100/avatar.png -->

Transform

• r?: number | 'portrait' | 'landscape' - Rotation
• z?: number - Zoom level
• flip?: 'h' | 'v' | 'hv' | 'vh' - Flip direction
• br?: number - Border radius

Format & Quality

• f?: string - Format ("auto", "webp", "jpg", etc.)
• q?: string | number - Quality ("auto" or 1-100)

Effects

• improve?: boolean | string | object - Auto-enhancement
• saturation?: number - Saturation (-100 to 100)
• contrast?: number - Contrast (-100 to 100)
• brightness?: number - Brightness (-99 to 100)
• sharpen?: boolean | number - Sharpen
• grayscale?: boolean - Convert to grayscale
