SDK 2.10.0 Updates Export, Automatic Resize, and Presentation Mode ​

  • Type: Capability change
  • Published: 2026-07-27
  • Effective date: 2026-07-27
  • Audience: Developers using SDK 2.x slide export, presentation mode, or dynamic container layouts
  • Action required: Before upgrading, review image and LaTeX export calls and the presentation-mode appId configuration

What Changed ​

SDK 2.10.0 includes four main updates:

  1. Upgraded slide export: editor.slides.exportImage(options) now provides size, view, and contain modes for fixed output dimensions, world-coordinate viewports, and content-fitting exports. LaTeX/TikZ export moves to the dedicated editor.slides.exportLatex(options) API.
  2. Automatic redraw after a container becomes visible: editor and presentation modes now provide resize(). The SDK observes container size changes and asks the embedded page to remeasure and redraw when a hidden container becomes visible.
  3. Updated presentation configuration: the application ID moves from top-level appId to auth.appId, the default route becomes /embed/present/:appId/:shareId, and presentation UI options add slidePanel, pencilToolbar, and zoomControl.
  4. Enhanced AI Chat draft image input: draft images now support both URLs and Base64 data, allowing host pages to preload images from different sources into AI Chat.

Upgrade Notes ​

Move the presentation application ID under auth:

ts
const presentation = await createPresentation(container, {
  auth: { appId: 'YOUR_APP_ID' },
  shareId: 'YOUR_SHARE_ID',
});

Select an explicit image export mode:

ts
const images = await editor.slides.exportImage({
  mode: 'view',
  viewBounds: { x: -5, y: -5, width: 10, height: 10, scale: 50 },
  pixelRatio: 2,
});

Use the dedicated API for LaTeX/TikZ:

ts
const items = await editor.slides.exportLatex({
  standalone: true,
});

Use Cases ​

  • Export PNG, JPG, or SVG by fixed size, viewport, or content bounds
  • Export editable, layout-friendly geometry as LaTeX/TikZ
  • Host an embedded canvas in hidden tabs, collapsible panels, or dynamic layouts
  • Control the slide panel, pencil toolbar, and zoom controls in presentation mode
