Pgmagick sharpen() method – Python

  • Last Updated : 26 May, 2020

The sharpen() function is an inbuilt function in the Pgmagick library which is used to sharpen the image. It uses a Gaussian operator of the given radius and standard deviation (sigma).

Syntax:

sharpen( radius, sd )

Parameters: This function accept two parameters as mentioned above and described below:

  • radius: This parameter stores the radius value of the sharpness.
  • sd: It is an optional parameter which stores the standard deviation of the image.

Return Value: This function returns the Pgmagick object with image added.

Input Image:



Example 1:




from pgmagick import Image, DrawableCircle, DrawableText
from pgmagick import Geometry, Color
  
# draw the image of dimension 600 * 600
  
img = Image('input.png')
# invoke shrpen function with radius 10 and standard deviation as 5
img.sharpen(10, 13)
  
# invoke write function along with filename
img.write('2_a.png')

Output:

Example 2:




# import library
from pgmagick import Image, DrawableCircle, DrawableText
from pgmagick import Geometry, Color
  
# Draw image of dimension 600 * 600 having background green
im = Image(Geometry(600, 600), Color("# 32CD32"))
  
# invoke DrawableCircle() function
circle = DrawableCircle(100, 100, 300, 20)
  
# invoke draw() function
im.draw(circle)
  
# set font size to 40px
im.fontPointsize(40)
  
# invoke DrawableText() function
text = DrawableText(250, 450, "GeeksForGeeks")
  
# invoke draw() function
im.draw(text)
  
# invoke sharpen function with radius as 9
im.sharpen(9)
  
# invoke write function along with filename
im.write('1_b.png')

Output:
