Atalasoft Web Document Viewer API Reference

The Atalasoft Web Document Viewer API reference contains information about Atalasoft HTML5 imaging controls.


There currently is a gap of functionality on the internet in that browsers currently only display "web native" image formats (PNG, JPEG, GIF, and SVG). Popular multipage document formats like PDF, TIFF and Office formats (like Excel and Word), all cannot be displayed natively on a web page. Atalasoft web controls solves this problem and provide JavaScript APIs to build viewer apps that:

  • Work on every HTML5 browser (including mobile browsers).
  • Display different types of images. PDF, TIFF, PNG, JPEG, BMP, GIF, PCX, PSD, PCD, RAW, WMF/EMF, TGA, JBIG2, Jpeg2000, DICOM, DWG, Xps, etc.
  • Modify document structure and save modified documents.
  • Enable annotations, thumbnails, and mobile support for a document.
  • Display and fill PDF forms.
  • Support text selection basing on PDF text layer or OCR data.
  • Effectively work with big documents - make it possible to stream individual pages on demand without downloading the entire document first.
  • Can be embedded into an existing web page or application.
