SetImageProgress

SetImageProgress() returns the progress of an image processing operation.

The format of the SetImageProgress method is:

    MagickBooleanType SetImageProgress(const char *text,
const MagickOffsetType offset,const MagickSizeType extent)

A description of each parameter follows:

image: the image.
text: description of the image processing operation.
offset: the offset relative to the extent parameter.
extent: the extent of the progress.

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:

image: the image.
progress_monitor: Specifies a pointer to a method to monitor progress of an image operation.
client_data: Specifies a pointer to any client data.

SetImageInfoProgressMonitor

SetImageInfoProgressMonitor() sets the image_info 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 SetImageInfoProgressMonitor method is:

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

A description of each parameter follows:

image_info: the image info.
progress_monitor: Specifies a pointer to a method to monitor progress of an image operation.
client_data: Specifies a pointer to any client data.
