monitor - Progress monitor support
unsigned int MagickMonitor( const char *text, const magick_int64_t quantum, const magick_uint64_t span, ExceptionInfo *exception );
MonitorHandler SetMonitorHandler( MonitorHandler handler );
MagickMonitor() calls the monitor handler method with a text string that describes the task and a measure of completion. The method returns True on success otherwise False if an error is encountered, e.g. if there was a user interrupt.
The format of the MagickMonitor method is:
unsigned int MagickMonitor ( const char *text, const magick_int64_t quantum, const magick_uint64_t span, ExceptionInfo *exception );
A description of each parameter follows:
The position relative to the span parameter which represents how much progress has been made toward completing a task.
The span relative to completing a task.
Return any errors or warnings in this structure.
SetMonitorHandler() sets the monitor handler to the specified method and returns the previous monitor handler.
The format of the SetMonitorHandler method is:
MonitorHandler SetMonitorHandler ( MonitorHandler handler );
A description of each parameter follows:
