Capture Freehand Ink Annotations in PDFs
Create apps that support handwritten notes in PDFs, allowing users to annotate documents directly with stylus, touch, or mouse input.
Freehand ink annotation support in a PDF component enables applications to capture and render freehand drawings directly on a PDF document, typically using input from a mouse, stylus, or touch device. It allows users to write, sketch, highlight, or mark up content in a natural way, with the annotations stored as standard PDF ink annotations that remain part of the document. For software developers, this capability adds interactive review and collaboration features to applications such as document viewers and form-processing systems, allowing users to provide visual feedback, sign documents, or annotate content without altering the original PDF structure.
