项目需求,提取pdf中图片,找半天的结果
1.fitz (我没找到元素定位的方法)
pip install pymupdf
import fitz
def extract_pic_from_pdf(pdf_path, pic_forder):
# 加载pdf
doc = fitz.open(pdf_path)
# 使用正则表达式来查找图片
checkIM = r"/Subtype(?= */Image)"
lenXREF = doc._getXrefLength()
# 提取图片
for i in range(1, lenXREF):
if not re.search(checkIM, doc._getXrefString(i)):
continue
pix = fitz.Pixmap(doc, i)
pix.writePNG(os.path.join(..., ...))
2.pdfminer (含元素定位,官网提取图片是个坑,大多数教程也是错的)
pip install pdfminer3k
from pdfminer.pdfparser import PDFParser,PDFDocument
from pdfminer.pdfinterp import PDFResourceManager, PDFPageInterpreter
from pdfminer.converter import PDFPageAggregator
from pdfminer.layout import LAParams, LTImage, LTTextBoxHorizontal, LTFigure
