# Module monitor Methods

## SetImageProgressMonitor

SetImageProgressMonitor() sets the image progress monitor to the specified method and returns the previous progress monitor if any. The progress monitor method looks like this:

          MagickBooleanType MagickProgressMonitor(const char *text,
      const MagickOffsetType offset,const MagickSizeType extent,
      void *client_data)

If the progress monitor returns MagickFalse, the current operation is interrupted.

The format of the SetImageProgressMonitor method is:

      MagickProgressMonitor SetImageProgressMonitor(Image *image,
        const MagickProgressMonitor progress_monitor,void *client_data)

A description of each parameter follows:

          MagickBooleanType MagickProgressMonitor(const char *text,
      const MagickOffsetType offset,const MagickSizeType extent,
      void *client_data)

If the progress monitor returns MagickFalse, the current operation is interrupted.

The format of the SetImageInfoProgressMonitor method is:

      MagickProgressMonitor SetImageInfoProgressMonitor(ImageInfo *image_info,
        const MagickProgressMonitor progress_monitor,void *client_data)
