Screenshot Capture
Capture seamless, full-page screenshots with smart element handling and stitching to diagnose rendering, SEO, and visual issues with confidence.
SLONQ Screenshot Capture Workflow
1. Capture Control Functions
At the heart of SLONQ’s system are two authoritative functions:
| Function | Purpose |
|---|---|
| captureFullPage | Powers the complete screenshot workflow, handling all capture, scrolling, and stitching operations |
| captureFullPageWithChecks | Adds critical size validation, ensuring compatibility with Chrome’s storage and SLONQ’s robust standards |
These functions orchestrate the entire process, from preparatory steps to final image delivery, ensuring every capture aligns with SLONQ’s exacting quality benchmarks.
2. Element Management: Overcoming Visual and SEO Barriers
Invisible yet impactful, fixed and sticky elements can distort both user and crawler perception. SLONQ’s system deploys:
| Function | Purpose |
|---|---|
| hideFixedElements | Temporarily hides fixed/sticky elements, removing repeated artifacts from every screenshot section |
| restoreFixedElements | Reliably restores the original state post-capture, ensuring zero disruption to site functionality |
By precisely managing DOM elements, SLONQ empowers you to capture a true, unified visual output—reflecting both user and crawler experience.
3. Precision Scrolling & Viewport Capture
Accurate rendering starts with precise navigation. SLONQ’s custom smooth scrolling logic ensures:
- Pixel-perfect alignment for each captured section
- Pause-and-capture logic that waits for all dynamic content, images, and fonts to load—mirroring how search engines experience your site
This rigorous approach guarantees that every screenshot reflects the full, interactive lifecycle of your page.
4. Seamless Image Stitching: No Artifacts, No Gaps
SLONQ’s robust image stitching pipeline includes:
| Stage | Description |
|---|---|
| Canvas Preparation | Initializes an OffscreenCanvas with full page dimensions |
| Viewport Capture | Captures each section as the page scrolls, ensuring complete coverage |
| Image Processing | Converts sections to high-fidelity ImageBitmap objects |
| Stitching Logic | Handles overlap between sections, preventing artifacts or duplication |
| Conversion | Outputs a unified, optimized image data URL—ready for analysis, sharing, or archiving |
This seamless process ensures your team can diagnose even the most elusive rendering issues—delivering actionable insights for SEO and beyond.
5. Intelligent Size Management & Error Recovery
With Chrome’s storage limitations in mind, SLONQ’s system delivers:
- Automatic size checks: Proactively alerts if a capture exceeds browser constraints
- Visual feedback: Notifies users at each process stage
- Fallback solutions: Offers alternative capture methods for oversized pages
Robust error detection—including tab focus monitoring and strategic recovery options—ensures you can trust every capture, every time.
