Python image processing module PIL (pillow)
The main role of pywin32
1. Capture window;
2. Simulate mouse and keyboard actions;
3. Automatically get the list of files under a certain path;
screenshot function
Find color click function ideas:
Grab a snapshot of the current screen, specify a coordinate and a color, and click on the coordinate if the color of the coordinate matches.
1. Grab a snapshot of the current screen () to return an image of the mode "RGB".
2. method() returns a pixel access object for reading and modifying pixels
3. Operating the mouse and keyboard with pywin32
King's Honor Auto Brush Adventure Mode Source Code Delivery：
Due to the different resolution, you have to modify the coordinates and colors accordingly in order to run it properly on your own computer.

Additional knowledge:python batch change one color to random color in all images in a folder
upfront
Requirement: sometimes need to change one color in the picture to another color, ps can help us to complete this task, but if there are a number of pictures, ps can not meet our needs, then we need to use python to help us quickly solve.

misdirection
Here you need the image to be in RGB mode, it can't be an L grayscale image, otherwise you will get the following error:
TypeError: 'int' object is not subscriptable
/questions/8220702/error-int-object-is-not-subscriptableIt explains the problem, but the main reason may lie in the fact that the image is a grayscale image, then the DATA data is empty, and the RGB color values cannot be extracted, and the program reports an error.
Random color
m = (160,190)# Take a random value of color 160-190
print("m=",m)
((i,j),(m,m,m))#color change
Here, it is random set random color value, change between 160-190, if you need to set other color value, you can change the moving range, or set m to a fixed constant, then represents a fixed color value.
P.S. Picture black and white swap
For binary graphs, the black and white colors in the image can be interchanged with each other via python.
from PIL import Image
import
for i in range(1,37551):
# Read in the picture
image = ('C:/Users/Administrator/Desktop/bbb/'+str(i).zfill(6)+'.png')
#image = ((64,64))
#Reverse
inverted_image = (image)
#SavePicture
inverted_image.save('C:/Users/Administrator/Desktop/bbb/'+str(i).zfill(6)+'.png')
in the end
Above this python to achieve the keysmith to find the color click function tutorial, the use of pywin32 and Pillow library is all I have to share with you, I hope to be able to give you a reference, and I hope that you have more support for me.
