使用Camelot查找PDF尺寸 [英] Find PDF Dimensions with Camelot

问题描述

我正在使用Camelot读取完整的PDF，并从每个PDF中提取大约112个属性.

I am using Camelot to read complete PDFs and extract about 112 attributes from each one.

我使用表格区域提取属性

I use table areas to extract the attributes

 test_variable = camelot.read_pdf(filename, flavor='stream', 
                 table_areas=['38, 340 ,50, 328']) 

问题是在所有文档中，同一属性的表区域不是恒定的.有时，我会在另一个文档中的x或y坐标上找到同一属性，仅向下几个像素.

The issue is the table area is not constant for the same attribute across all documents. Sometimes I would find the same attribute a few pixels down in x or y-coordinates i another document.

 test_variable = camelot.read_pdf(filename, flavor='stream', 
                 table_areas=['38,350,50,338']) 

是否有一种方法可以从同一区域获取确切的属性，而与提取任何文档无关?

Is there a way to get the exact attribute from the same area regardless of extraction of any document?

推荐答案

也许table_regions选项(在0.7中引入)可以为您提供帮助.

Maybe the option table_regions (introduced in 0.7) can help you.

https://camelot-py .readthedocs.io/en/master/user/advanced.html#specify-table-regions

指定table_regions时，Camelot将仅分析指定的区域以查找表."

"When table_regions is specified, Camelot will only analyze the specified regions to look for tables."

您可以定义一个较大的table_regions区域，而Camelot将在该区域中搜索表.

You can define a larger table_regions area and Camelot will search for tables in this area.
