# Wand statistic function – Python

• Last Updated : 02 Aug, 2021

The statistic() function is an inbuilt function in the Python Wand ImageMagick library which is used to replace each pixel with the statistic results from neighboring pixel values. The width & height defines the size, or aperture, of the neighboring pixels.

Syntax:

`statistic(stat, width, height, channel)`

Parameters: This function accepts four parameters as mentioned above and defined below:

• stat: This parameter stores the type of statistic to calculate. Some of the available statistics are ‘undefined’, ‘gradient’, ‘maximum’, ‘mean’, ‘median’, ‘minimum’, ‘mode’, ‘nonpeak’, ‘root_mean_square’, ‘standard_deviation’.
• width: This parameter stores the size of neighboring pixels on the X-axis.
• height: This parameter stores the size of neighboring pixels on the Y-axis.
• channel: This parameter stores the available color channel.

Return Value: This function returns the Wand ImageMagick object.

Original Image: Example 1:

## Python3

 `# Import library from Image``from` `wand.image ``import` `Image` `# Import the image``with Image(filename ``=``'../geeksforgeeks.png'``) as image:``    ``# Clone the image in order to process``    ``with image.clone() as statistic:``        ``# Invoke statistic function with statistic as median, width as 20``        ``# height as 10, channel as 'yellow'``        ``statistic.statistic(``'median'``, ``20``, ``10``, ``'yellow'``)``        ``# Save the image``        ``statistic.save(filename ``=``'statistic1.jpg'``)`

Output: Example 2:

## Python3

 `# Import libraries from the wand ``from` `wand.image ``import` `Image``from` `wand.drawing ``import` `Drawing``from` `wand.color ``import` `Color` `with Drawing() as draw:``    ``# Set Stroke color the circle to black``    ``draw.stroke_color ``=` `Color(``'black'``)``    ``# Set Width of the circle to 2``    ``draw.stroke_width ``=` `1``    ``# Set the fill color to 'White (# FFFFFF)'``    ``draw.fill_color ``=` `Color(``'white'``)` `    ``# Invoke Circle function with center at 50, 50 and radius 25``    ``draw.circle((``200``, ``200``), ``# Center point``                ``(``100``, ``100``)) ``# Perimeter point``    ``# Set the font style``    ``draw.font ``=` `'../Helvetica.ttf'``    ``# Set the font size``    ``draw.font_size ``=` `30``    ` `    ``with Image(width ``=` `400``, height ``=` `400``, background ``=` `Color(``'# 45ff33'``)) as pic:``        ``# Set the text and its location``        ``draw.text(``int``(pic.width ``/` `3``), ``int``(pic.height ``/` `2``), ``'GeeksForGeeks !'``)``        ``# Draw the picture``        ``draw(pic)``        ``# Invoke statistic function with statistic as root_mean_square, width as 20``        ``# height as 10, channel as 'green'``        ``pic.statistic(``'root_mean_square'``, ``20``, ``10``, ``'green'``)``        ``# Save the image``        ``pic.save(filename ``=``'statistic2.jpg'``)`
