About

ATBinHex is a control that implements the quick file (stream) viewer. Only visible part of file (or stream) is loaded into viewer, so it's suitable to show files of unlimited size.

Original Delphi code is used for a long time inside "Universal Viewer" application.

Limitations of Lazarus port

• Some features were disabled via ATBinHexOptions.inc file (searching of text, printing, RegEx highlighting of URLs).
• Removed method OpenFile, because it used Win32 API; use OpenStream instead.
