TextFragmentAbsorber Only Getting First 4 Fragments


I’m trying to extract all of the text from a PDF page so that I can change the text’s color with Aspose 10.6.0. I’m using the TextFragmentAbsorber, but no matter what PDF I use it’s only returning me the first 4 text fragments in its Results View - the rest of the text fragments I can see in its Non-Public Members but I can’t figure out a way of accessing them…

Here’s how I’m using TextFragmentAbsorber to extract the text:

var page = pdfDoc.Pages[pageNum];// get a page from the PDF doc
var tfa = new TextFragmentAbsorber();// create the TextFragmentAbsorber
var tfc = tfa.TextFragments;// get text fragments for page

foreach (TextFragment tf in tfc)// loop through each text fragment and set it’s color to black
tf.TextState.ForegroundColor = Color.Black;

However, even though tfa.TextFragments above has a count of 13 for this particular PDF page, only its Non-Public Members contain all 13 fragments, its Result View only contains the first 4 fragments (see attached screen shot).

Am I using TextFragmentAbsorber incorrectly? Or should I be using another strategy to change the text color for this PDF page?

Thank you,

Ah - I dug a little deeper into the IndexOfOutRange exception I was getting when trying to access the fragments in TextFragments beyond the 4th element and found, buried in the base of the exception, the message: "At most 4 elements (for any collection) can be viewed in evaluation mode."

Fair enough - but a little heads up in the details or documentation for TextFragmentAbsorber.TextFragments would have saved me a lot of time and headache.
