Slideshow Capture

Build presentation steps instantly by capturing screenshots as you navigate the application. Each screenshot becomes a full-canvas slide with automatic crossfade transitions between steps.

Slideshow capture is the fastest way to build a presentation in NeoArc Studio. Instead of manually adding shapes, configuring visibility intents, and setting up transitions for each step, you simply navigate around the application taking screenshots. When you finish, each screenshot becomes a full-canvas slide with smooth crossfade transitions generated automatically. A five-minute walkthrough that would take 30 minutes to author by hand takes 30 seconds with slideshow capture.

How It Works

Key Capabilities

One-Click Capture
Click the Capture button on the floating control bar to save a JPEG screenshot of the current page. The button disables during capture to prevent duplicates and re-enables automatically when the screenshot is saved.
Automatic Crossfade Transitions
Each slide fades in while the previous slide fades out, creating smooth crossfade transitions between steps. No manual animation configuration required.
Survives Navigation
The capture session persists as you navigate between pages, diagrams, and views. Browse freely through the entire application while the floating control window stays on top.
Frame-Aware Viewport
When your presentation has a configured frame (16:9, 4:3, or 1:1), slideshow capture automatically sets each step's viewport to match the frame dimensions for consistent framing.

Floating Control Window

The capture control bar is a compact floating window (380 x 52 pixels) that sits above all other windows. It provides three actions and a slide counter:

ButtonAction
CaptureSave a JPEG screenshot of the current page. Buttons disable during capture and re-enable when done.
FinishEnd the session, route back to the presentation, and generate steps from all captured screenshots.
CancelDiscard all captures and return to the presentation without changes.

What Gets Generated

For each captured screenshot, slideshow capture creates a presentation step containing:

Full-Canvas Image Shape
The screenshot is embedded as a full-canvas image shape sized to the presentation frame. Image data is stored as a data URL directly in the step intents.
Visibility Intents
Each step has a fadeIn intent for the new slide and a fadeOut intent for the previous slide. The first step has only a fadeIn since there is no previous slide.
Viewport Positioning
When the presentation frame is configured, each step's viewport is set to the frame coordinates and dimensions for consistent viewing.

Use Cases

Application Walkthroughs
Capture each screen of a workflow to create a step-by-step tour of the application. Navigate through pages, click through forms, and capture each state.
Architecture Overview Decks
Capture different diagram views, ERD views, and graph views to build a complete architecture deck. Each view becomes a slide with professional crossfade transitions.
Onboarding Presentations
Walk through the key areas of a workspace and capture screenshots at each stop. New team members get a guided tour that plays back as a presentation.
Review Board Submissions
Quickly assemble screenshots of relevant diagrams, schemas, and API documentation into a presentation for architecture review meetings.
Animated Presentation Diagrams

Turn any architecture diagram into a step-by-step animated presentation with visibility actions, audio narration, viewport animation, speaker notes, and multiple standalone presentations per diagram.

Diagram Editor

Create architecture diagrams, ERDs, flowcharts, and network diagrams with icon libraries from Azure, AWS, Kubernetes, CNCF, Lucide and brand collections. Includes presentation mode with animated viewport transitions, infographic mode with canvas presets, version snapshots, architecture transitions, and full auto-layout.

Infographic Mode

Create fixed-canvas visual assets with a comprehensive shape palette including interactive shapes with configurators, layers panel with z-order control, shape grouping, visual effects, gradient fills, a component library, canvas presets, and direct export to SVG, PNG, JPEG, and PDF.
