The charcoal() function is an inbuilt function in the Pgmagick library which is used to to add a charcoal filter to the image. The function returns the true value on success.
Syntax:
charcoal(factor)Parameters: This function accepts single parameters as mentioned above and described below:
- factor: This parameter stores the value of the charcoal factor which is to be apply on 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 charcoal function with factor 8 img.charcoal( 8 ) # 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 charcoal function with factor 5 im.charcoal( 5 ) # invoke write function along with filename im.write( '1_b.png' ) |
