The solarize() function is an inbuilt function in the Pgmagick library that is used to negate all pixels above the threshold level. The function returns the true value on success.
Syntax:
solarize(thresholdLevel)Parameters: This function accepts a single parameter thresholdlevel which is used to specify the threshold level between 0 to 100.
Return Value: This function returns the Pgmagick object with image added.
Input Image:
Example 1:
Python3
from pgmagick import Image, DrawableCircle, DrawableTextfrom pgmagick import Geometry, Color# draw the image of dimension 600 * 600img = Image('input.png')# invoke solarize function with factor as 60 img.solarize(60)# invoke write function along with filenameimg.write('2_a.png') |
Output:
Example 2:
Python3
# import libraryfrom pgmagick import Image, DrawableCircle, DrawableTextfrom pgmagick import Geometry, Color# Draw image of dimension 600 * 600 having background greenim = Image(Geometry(600, 600), Color("# 32CD32"))# invoke DrawableCircle() functioncircle = DrawableCircle(100, 100, 300, 20)# invoke draw() functionim.draw(circle)# set font size to 40pxim.fontPointsize(40)# invoke DrawableText() functiontext = DrawableText(250, 450, "GeeksForGeeks")# invoke draw() functionim.draw(text)# invoke size function with factor as 10im.solarize(10)# invoke write function along with filenameim.write('1_b.png') |
