This year's National Day is also the Mid-Autumn Festival, so first of all, I wish you all a happy holiday, and in this article we use Python to add a little national flag or mooncake to our avatars.
flag (of a country)
For the national flag, we can use Python to draw one. The Python library used is the familiar turtle, and our five-starred red flag consists of the following elements: a red background, a yellow main star, and four yellow secondary stars.
First draw a rectangle with a red background, the code is implemented as follows:
(600, 400, 0, 0)
("red")
The effect is as follows:
Next draw a main star and the code is implemented as follows:
("yellow")
('yellow')
(10)
# The main star
turtle.begin_fill()
()
(-280,100)
()
for i in range (5):
(150)
(144)
turtle.end_fill()
The effect is as follows:
Finally four secondary stars are drawn and the code is implemented as follows:
# Adjunct 1 turtle.begin_fill() () (-100,180) (305) () for i in range (5): (50) (144) turtle.end_fill() # Adjunct 2 turtle.begin_fill() () (-50,110) (30) () for i in range (5): (50) (144) turtle.end_fill() # Adjunct 3 turtle.begin_fill() () (-40,50) (5) () for i in range (5): (50) (144) turtle.end_fill() # Substar 4 turtle.begin_fill() () (-100,10) (300) () for i in range (5): (50) (144) turtle.end_fill()
The final result is as follows:
mooncake (esp. for the Mid-Autumn Festival)
For a mooncake, you can also draw one in Python. The mooncake composition consists of the following elements: an outer circular patterned outline, an inner outline, and text.
First of all, let's draw the pattern outline of the outer circle, the code is implemented as follows:
(100)
("#F5E16F")
for i in range(20):
# Move 18 degrees clockwise
(18)
turtle.begin_fill()
# Distance moved forward
(220)
# Draw a semicircle with a radius of 40
(40, 180)
# Return to (0, 0) after drawing the semicircle #
(0, 0)
(360)
turtle.end_fill()
The effect is as follows:
Then proceed to draw the inner contour, the code is implemented as follows:
# Set the brush thickness
(20)
# Fill colors (external, internal)
("#F5E16F", "#FF9933")
goto(0, -200)
# Ready to start filling
turtle.begin_fill()
(200)
# End of filling
turtle.end_fill()
(360)
('#F5E16F')
goto(0, -180)
for i in range(12):
turtle.begin_fill()
(60, 120)
(180)
(60, 120)
turtle.end_fill()
The effect is as follows:
Finally to add text, such as bean paste filling to add the word bean paste, the code to achieve the following:
("#F5E16F")
("Douzha.", font=("Scribe.", 60, "bold"))
The final result is as follows:
Avatar plus flag (mooncake)
Finally, we add the flag or mooncake we just drew to our avatar, using the Python library OpenCV, which is installed using thepip install opencv-python command is sufficient; if it is too slow, you can use thepip install -i /pypi/simple/ opencv-python Accelerated download and installation.
This function is also relatively simple to implement, only a dozen lines of Python code can be done, the code implementation is as follows:
# Reading avatars and flag patterns
img_head = ('')
img_flag = ('')
# Get avatar and flag pattern widths
w_head, h_head = img_head.shape[:2]
w_flag, h_flag = img_flag.shape[:2]
# Calculate pattern scaling
scale = w_head / w_flag / 4
# Zoom Patterns
img_flag = (img_flag, (0, 0), fx=scale, fy=scale)
# Get new width after scaling
w_flag, h_flag = img_flag.shape[:2]
# Merge images by 3 channels
for c in range(0, 3):
img_head[w_head - w_flag:, h_head - h_flag:, c] = img_flag[:, :, c]
# Save the final result
('new_head.jpg', img_head)
Suppose my original avatar was as follows:
Add a small flag to the avatar with the following effect:
Add a small mooncake to the avatar with the following effect:
