使用Python实现将图片(JPG/PNG)转换为PDF

pip install Spire.PDF

from spire.pdf.common import *
from spire.pdf import *
import os

# 创建 PdfDocument 对象
doc = PdfDocument()

# 设置页面边距为 0
doc.PageSettings.SetMargins(0.0)

# 获取图片存储文件夹路径
path = "C:\Users\Administrator\Desktop\Images\"
files = os.listdir(path)

# 遍历文件夹中的文件
for root, dirs, files in os.walk(path):
    for file in files:

        # 加载特定的图像
        image = PdfImage.FromFile(os.path.join(root, file))
        
        # 获取图像的宽度和高度
        width = image.PhysicalDimension.Width
        height = image.PhysicalDimension.Height

        # 添加页面，其大小与图像相同
        page = doc.Pages.Add(SizeF(width, height))

        # 在页面的 (0, 0) 位置绘制图像
        page.Canvas.DrawImage(image, 0.0, 0.0, width, height)
      
# 保存文件
doc.SaveToFile("output/CombineImages.pdf")
doc.Dispose()
