Runtime logging facade (HPDFLogger)

The HPDFLogger unit provides a process-wide runtime logging facade for HotPDF diagnostics without compile-time switches or custom rebuilds

Main types

• THPDFLogger is the logging facade class and is exposed through the global HPDFLog instance
• THPDFLogLevel controls severity filtering with llOff, llError, llWarning, llInfo, and llDebug
• THPDFLogTarget and THPDFLogTargets select file output, OutputDebugString, console output, or any combination of targets

Common configuration

uses
  HPDFDoc, HPDFLogger;

begin
  HPDFLog.Level := llInfo;
  HPDFLog.Targets := [ltFile, ltOutputDebugString];
  HPDFLog.FileName := 'hotpdf.log';
end;

Logging methods

• Log writes a message with an explicit severity level
• Debug, Info, Warning, and Error are convenience wrappers for common severity levels
• Clear truncates the configured file target when file logging is enabled
