Runtime logging facade (HPDFLogger)
The HPDFLogger unit gives you a process-wide runtime logging facade for HotPDF diagnostics — no compile-time switches and no custom rebuilds required
Main types
THPDFLoggeris the logging facade class, created automatically in the unit's initialisation section and exposed as the globalHPDFLogvariable, so application code only configures properties and calls methodsTHPDFLogLevelis the severity enumeration, orderedllOff(suppress everything) →llError→llWarning→llInfo→llDebug(most verbose); a record passes the filter only when its level is at or below the facade's LevelTHPDFLogTargetandTHPDFLogTargetschoose the output destinations:ltFile(writes to the file named by FileName), ltOutputDebugString, console output, or any combination of targets
