Golang MagickClearException Examples

Example #1

File: canvas.go Project: phacops/canvas

// Returns the latest error reported by the MagickWand API.
func (self *Canvas) Error() error {
	var t C.ExceptionType
	ptr := C.MagickGetException(self.wand, &t)
	message := C.GoString(ptr)
	C.MagickClearException(self.wand)
	C.MagickRelinquishMemory(unsafe.Pointer(ptr))
	return errors.New(message)
}

Example #2

File: magick_wand.go Project: rli-diraryi/paint

/* Returns the severity, reason, and description of any error that occurs when
   using other methods in this API.
*/
func (w *MagickWand) Exception() (string, int) {
	var severity C.ExceptionType
	errPtr := C.MagickGetException(w.wand, &severity)
	C.MagickClearException(w.wand)
	err := C.GoString(errPtr)
	C.MagickRelinquishMemory(unsafe.Pointer(errPtr))
	return err, int(severity)
}

Example #3

File: pixel_iterator.go Project: phacops/canvas

func (self *PixelIterator) Error() error {
	var exception C.ExceptionType

	ptr := C.MagickGetException(self.iterator, &exception)
	message := C.GoString(ptr)

	C.MagickClearException(self.iterator)
	C.MagickRelinquishMemory(unsafe.Pointer(ptr))

	return errors.New(message)
}

Example #4

File: magick_wand_exception.go Project: qwo/abelana-gcp

// Clears any exceptions associated with the wand
func (mw *MagickWand) clearException() bool {
	return 1 == C.int(C.MagickClearException(mw.mw))
}

Example #5

File: canvas.go Project: jmrobles/canvas

// Returns the latest error reported by the MagickWand API.
func (self Canvas) Error() error {
	var t C.ExceptionType
	message := C.MagickGetException(self.wand, &t)
	C.MagickClearException(self.wand)
	return fmt.Errorf(C.GoString(message))
}
