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")
