如何从提取的PDF文本中获取字体属性（字体大小，字体样式，字体颜色）？ [英] How to get font properties(font size, font style, font colour) from the extracted pdf text?

问题描述

大家好，



我使用下面的代码从pdf文件中提取文字，

Hi All,

I am using below code to extract text from pdf file,

public string ReadPdfFile()
        {
            string strText = string.Empty;
            try
            {
                PdfReader reader = new PdfReader(@"\\FilePath");

                for (int page = 1; page <= reader.NumberOfPages; page++)
                {
                    ITextExtractionStrategy its = new iTextSharp.text.pdf.parser.SimpleTextExtractionStrategy();
                    String s = PdfTextExtractor.GetTextFromPage(reader, page, its);
                    
                    s = Encoding.UTF8.GetString(ASCIIEncoding.Convert(Encoding.Default, Encoding.UTF8, Encoding.Default.GetBytes(s)));
                    strText = strText + s;

                }
                reader.Close();
            }
            catch (Exception ex)
            {
            }
            return strText;
        }

我需要获取所提取文本的字体属性（字体大小，字体样式，字体颜色）比较。

我需要在这行代码下面应用这个逻辑，

I need to get the font properties(font size, font style, font colour) of the extracted text for comparison.
I need that logic to be applied below this line of code,

ITextExtractionStrategy its = new iTextSharp.text.pdf.parser.SimpleTextExtractionStrategy();
String s = PdfTextExtractor.GetTextFromPage(reader, page, its);

有谁知道如何从提取的pdf文本中获取字体大小，字体样式，字体颜色等字体属性。



提前致谢，
