以下是使用Python将PDF转换为图像的代码:
```
import cv2
import fitz
def pdf_to_image(pdf_path, output_path):
"""
Convert PDF to image using PyMuPDF and OpenCV
:param pdf_path: path to PDF file
:param output_path: path to output image file
"""
# Open PDF file
doc = fitz.open(pdf_path)
# Iterate through each page
for i in range(doc.page_count):
# Get the page
page = doc.load_page(i)
# Render the page as a pixmap
pix = page.get_pixmap()
# Convert the pixmap to a numpy array
img = cv2.cvtColor(
cv2.UMat(pix.samples), cv2.COLOR_RGB2BGR
).get()
# Save the image
cv2.imwrite(f"{output_path}-{i}.png", img)
# Close the PDF file
doc.close()
# Example usage
pdf_to_image("example.pdf", "output")
```
这个函数将打开指定的PDF文件,并将每一页转换为OpenCV可用的图像。图像将保存在指定的输出路径中,文件名将附加页面号码。在这个例子中,输出图像将被保存为"output-0.png","output-1.png"等。
