Boost Your PDF Workflow with Dynamsoft Document Viewer SDK Version 2.1

The latest release of Dynamsoft Document Viewer (DDV) SDK Version 2.1 introduced several new features and improvements designed to enhance PDF document viewing and editing. In this blog post, we’ll focus on three highlights of this release: PDF handling enhancements, the new magnifier tool, and the flatten mode for annotations.

1. Enhanced PDF Loading and Saving Performance

Handling large PDF documents can often be a bottleneck in digital workflows. DDV v2.1 addresses this with substantial performance upgrades, allowing the SDK to process documents with over 1,000 pages seamlessly. These improvements not only make the viewer more efficient but also reduce delays when saving edited files back into the PDF format.

This improvement is particularly beneficial for industries managing extensive document archives, such as legal, healthcare, and finance. With faster PDF operations, users can focus more on critical tasks rather than waiting for files to load or save. The table below highlights the exceptional performance of our DDV PDF processing capability for both image-based and text-based PDFs, regardless of page count. Witness significantly faster load and save time that ensures a seamless experience, even with larger documents.

Document Type Page Count File Size (MB) Load Time (Seconds) Peak Memory Usage During Load (MB) Save to PDF Time (Seconds) Peak Memory Usage During Save (MB)
Image PDF (96 DPI, 2160x3840, Convert Mode: ImageOnly) 100 92.1 1.3 650 1.33 780
  500 460 4.5 890 12.2 1,934
  1000 921 9.7 960 24.07 4,000
Text PDF (A4, Convert Mode: Render) 100 2.61 0.41 330 0.29 340
  500 13 1.19 446 2.43 556
  1000 26.1 2.78 540 4.86 590

2. Precision Cropping with the New Magnifier

Working on touchscreen devices often presents challenges in precision, especially during cropping or editing. To address this, DDV v2.1 introduces the magnifier tool.

This feature displays a zoomed-in corner view when interacting with the crop or edit boundaries, ensuring users can adjust their edits with pinpoint accuracy—even when their finger obscures the boundary line. This enhancement is perfect for mobile and tablet users, offering a smoother and more intuitive editing experience.

3. Flatten Mode for Individual Annotations

Annotations are a powerful tool for collaboration, but sometimes, you need to lock changes or finalize annotations for distribution. The new flatten mode allows annotations to be merged directly onto the base document layer.

By setting an annotation’s flattened property, you can ensure that it becomes a permanent part of the document, unaffected by further edits. This feature is preserved when saving the document as a PDF, making it ideal for scenarios requiring finalized or non-editable annotations, such as legal agreements, compliance documentation, or medical records. Users now have the flexibility to select and flatten individual annotations, a significant improvement over the previous version where flattening was applied to all annotations at once.

Below are some practical use cases where selectively flattening individual annotations while leaving others as markups would be beneficial:

  • Flattened Annotations: Redacted sensitive information (e.g., hidden text or confidential clauses) to ensure it cannot be altered or revealed.

  • Markup Annotations: Highlighted or underlined text that serves as editable references for legal teams during review.

2. Compliance Documentation

  • Flattened Annotations: Official signatures, stamps, or regulatory compliance notes that must not be changed.

  • Markup Annotations: Comments or highlights for internal review and revisions before final submission.

3. Medical Records and Reports

  • Flattened Annotations: Diagnostic notes or conclusions finalized by a doctor for a patient’s medical record.

  • Markup Annotations: Comments or recommendations left for internal use by medical staff for future edits.

The new flatten mode for individual annotations brings the flexibility and precision of document workflows to the next level. By enabling users to selectively finalize certain annotations while keeping others editable, it bridges the gap between collaboration and finalization.
