Finished product drawing!
(eyes full of love for your shape ~)
Do you want to make such a picture? So let's start now~1. What needs to be prepared
1 photo of super invincible, lovely and greasy girl ticket! python (python 3.7 is used here) Required Library cv2: used to read photos PIL: used to generate new pictures Computers with good performance (if you haven't contacted python, you don't want / can't configure the environment, install cv2, PIL and other libraries, or the computer performance is not enough, it is strongly recommended to use Huawei cloud's ModelArts for development to directly solve various problems of environment configuration and computer performance ~)2. Basic ideas
To achieve this effect, you need to first have a picture, extract its pixel information, and then assign it to a new picture full of text, you can get a new picture as shown in the above figure! No more nonsense, let's start next~3. Operation process
1. Import the used library first (the functions of the two are described in 1)
import cv2 from PIL import Image, ImageDraw, ImageFont
2. Then start to declare the drawing method
Here are two parameters: the path of the original image and the text to be writtendef draw(pic, draw_text):
3. Then read the picture
Use the imread method in cv2 to read the picture information, Use the Image method in PIL to create a new Image with the same size as the source Image and a white backgroundimg = cv2.imread(pic) blank = Image.new("RGB", [img.shape[1], img.shape[0]], "white") drawObj = ImageDraw.Draw(blank) # Tell the program, we will write on this picture next!
4. Declare some parameters of the drawing (these parameters are the best size I get through many experiments ~)
n = 10 # Read pixel interval m = 9 # Font size font_path = 'Where do you use fonts' # Path to font font = ImageFont.truetype(font_path, size=m) # Assign font information to font variable for subsequent use
5. Next is the most critical step! Write the text and color the image according to the source image
Through two for loops, locate the color block of each text in turn (the middle interval n is because the text is much larger than the pixel block, and it is impossible to arrange the text completely according to the position and color of each pixel) Use the text() method to fill in the colored text. Several parameters represent:[j, i] -- Coordinate position draw_text[int(j / n) % len(draw_text)] -- Find out which text to write (such as the first few words in "I love you") fill=(img[i][j][2], img[i][j][1], img[i][j][0]) -- Represents the color of the corresponding position of the source image (three represent respectively RBG Color value) font -- It's obviously font information~ for i in range(0, img.shape[0], n): for j in range(0, img.shape[1], n): drawObj.text( [j, i], draw_text[int(j / n) % len(draw_text)], fill=(img[i][j][2], img[i][j][1], img[i][j][0]), font=font ) # Fill in the text in the order of the sentence
6. Write completed, export picture
blank.save('img_' + pic) # Save the generated picture
7. Call our encapsulated methods~
Input image path and target text, run ~ a unique expression map will be finished! draw('1.jpg ', "I love you") Attach the full code (remember to change the font path to your own computer's)import cv2 from PIL import Image, ImageDraw, ImageFont def draw(pic, draw_text): img = cv2.imread(pic) blank = Image.new("RGB", [img.shape[1], img.shape[0]], "white") drawObj = ImageDraw.Draw(blank) n = 10 m = 9 font = ImageFont.truetype(font_path, size=m) for i in range(0, img.shape[0], n): for j in range(0, img.shape[1], n): drawObj.text( [j, i], draw_text[int(j / n) % len(draw_text)], fill=(img[i][j][2], img[i][j][1], img[i][j][0]), font=font ) blank.save('img_' + pic) draw('1.jpg', "I love you!")

Since we can make pictures one by one, why don't we connect them to make an expression video? Of course!
