由 好久不见. 提交于 2019-12-13 03:10:19
问题 I am trying to parse a PDF-book, but I only need the main body WITHOUT footers, headers or footnotes. I looked through pdfminer documentation but I haven't succeeded yet. Here is the code I use for getting the text: from pdfminer.converter import TextConverter from pdfminer.pdfinterp import PDFPageInterpreter from pdfminer.pdfinterp import PDFResourceManager from pdfminer.pdfpage import PDFPage with open(pdfname, 'rb') as fh: for page in PDFPage.get_pages(fh, caching=True, check_extractable

目录 一、背景 二、问题 三、解决 四、一顿分析及 Shell 操作 五、后续 一、背景 本想将 PDF 文件转换为 Word 文档，然后网上搜索了一下发现有挺多转换的软件。有的是免费的、收费，咱也不知哪个好使，还得一个个安装试用。先不说能不解决问题，就这安装试用想想就脑壳疼。便想起了"Python 大法"，随即搜了几篇看起来 比较完整的博客 ，二话不说粘贴复制，改改运行试试。使用环境(python3.6+pdfminer3k)，代码这里就不放出来了。 二、问题 运气不好，这一试就报错 WARNING:root:GBK-EUC-H ，然后又搜了一下有 同样的报错问题 ，但是这篇博客没啥大用，仅仅是知道缺了相关的字体文件，通过其中的链接顺藤摸瓜找到了 github 上的字体文件列表页 https://github.com/euske/pdfminer/tree/f1d5d681b6d2ab0ddeaea925ba784ebb94f6d509/pdfminer/cmap 三、解决 下载了报错的对应文件 GBK-EUC-H.pickle.gz ，然后将其文件解压把放置 Python 的安装目录下 Lib\site-packages\pdfminer\cmap 路径中，再次运行又报错 "pdfminer.converter:undefined: <PDFCIDFont: basefont=

Python pdfminer extract image produces multiple images per page (should be single image)

由 徘徊边缘 提交于 2019-12-11 02:19:26
问题 I am attempting to extract images that are in a PDF. The file I am working with is 2+ pages. Page 1 is text and pages 2-n are images (one per page, or it may be a single image spanning multiple pages; I do not have control over the origin). I am able to parse the text out from page 1 but when I try to get the images I am getting 3 images per image page. I cannot determine the image type which makes saving it difficult. Additionally trying to save each pages 3 pictures as a single img provides
