AndroidPdfViewer
AndroidPdfViewer is a user interface library for Android applications that provides a view for displaying PDF documents. It utilizes the PdfiumAndroid rendering engine to decode PDF files into bitmaps for display on mobile devices.
The library includes built-in support for zooming, scaling, and scroll navigation. It allows for the loading of PDF data from various document sources and provides controls to adjust rendering quality and visual fidelity.
The component handles mobile document navigation through features such as page filtering, hyperlink detection, and customizable scroll handles. It also manages document magnification via double-tap gestures and defined zoom limits.
