python --给图片加文字
- import cv2
- from PIL import ImageFont, ImageDraw, Image
- import numpy as np
-
- bk_img = cv2.imread(r"C:\Users\ht-desktop-001\Desktop\088.png")
- #设置需要显示的字体
- fontpath = "msyhbd.ttc"
- font = ImageFont.truetype(fontpath, 32)
- img_pil = Image.fromarray(bk_img)
- draw = ImageDraw.Draw(img_pil)
- #绘制文字信息
- draw.text((1, 3), "Hello World", font = font, fill = (0, 0, 0))
- draw.text((100, 350), "你好", font = font, fill = (255, 255, 255))
- bk_img = np.array(img_pil)
-
- cv2.imshow("add_text",bk_img)
- cv2.waitKey()
- cv2.imwrite("add_text.jpg",bk_img)
-
方法二
- pip install opencv-python
-
.利用putText方法来实现在图片的指定位置添加文字
putText(img,text,org,fontFace,fontScale,color,thickness=None,lineType=None,bottomLeftOrigin=None)
img:操作的图片数组
text:需要在图片上添加的文字
fontFace:字体风格设置
fontScale:字体大小设置
color:字体颜色设置
thickness:字体粗细设置
案例
- import cv2
-
- #加载背景图片
- bk_img = cv2.imread("background.jpg")
- #在图片上添加文字信息
- cv2.putText(bk_img,"Hello World", (100,300), cv2.FONT_HERSHEY_SIMPLEX,
- 0.7,(255,255,255), 1, cv2.LINE_AA)
- #显示图片
- cv2.imshow("add_text",bk_img)
- cv2.waitKey()
- #保存图片
- cv2.imwrite("add_text.jpg",bk_img)
-
注:在使用putText方法在图片上添加文字的时,无法直接添加中文和无法导入字体文件,接下来我们利用另一库PIL来解决这个问题
- from PIL import Image, ImageDraw, ImageFont
-
- # Open the image
- image = Image.open(r"D:\yi\yan_lian\media\share\2_qr.jpg")
-
- # Create a drawing object
- draw = ImageDraw.Draw(image)
-
- text = "10000"
-
- # Define the font style and size
- font = ImageFont.truetype(r"D:\yi\yan_lian\SIMLI.TTF", 60)
-
- # Define the position where the text will be added
- position = (410, 1100)
-
- # Define the color of the text
- color = (0, 0, 0) # white color
-
- # Add the text to the image
- draw.text(position, text, font=font, fill=color)
-
- # Save the modified image
- image.show()
- # image.save("modified_image.jpg")
