How to access the getValidCharCnt() method (or equivalent replacement) of PDFTextStripper

[Karen Madore <Ka...@ascnet.com>]

Hello,

We are migrating from PDFBox from 1.8.16 to 2.0.21 and am looking for the equivalent method to the getValidCharCnt(). Previously this method was accessible via PDFTextStripper class but now it does not seem to recognize this method and I am unable to find a suitable replacement method. Below is the line of code I am trying to migrate.

_hasText = (_hasText || stripper.getValidCharCnt() > 0) ? true : false;

Imports used are:
import org.apache.pdfbox.text.PDFTextStripper;
import org.apache.pdfbox.multipdf.Splitter;

I am new to PDFBox so this might be a newbie question.

Cheers,

Karen Madore

Hi,

If you only need to know whether it is > 0, then you don't need it at 
all. Because > 0 means you got text.

If you want a count, then extend the stripper and extend showGlyph(). 
Here is how our "big sister project" Apache Tika does it:

     @Override
     protected void showGlyph(Matrix textRenderingMatrix, PDFont font, 
int code, String unicode, Vector displacement) throws IOException
     {
         super.showGlyph(textRenderingMatrix, font, code, unicode, 
displacement);
         if (unicode == null || unicode.isEmpty()) {
             unmappedUnicodeCharsPerPage++;
         }
         totalCharsPerPage++;
     }
