iText-使用PdfCleanUpProcessor后输出文件字体看起来模糊 [英] iText - Output file font looks blurry after using PdfCleanUpProcessor

问题描述

我正在使用iText 5.5.8完全按照

I'm using iText 5.5.8 to remove some text in a rectangle in my PDF, exactly following this example. E.g. the code snippet like below:

final Rectangle rect = new Rectangle(0, 12, 300, 21);
final PdfReader reader = new PdfReader(inputPDF);
final PdfStamper stamper = new PdfStamper(reader, new FileOutputStream(outputPDF));
for (int i=1;i<=reader.getNumberOfPages();i++) {        
    cleanUpLocations.add(new PdfCleanUpLocation(i, rect, BaseColor.WHITE));
}

PdfCleanUpProcessor cleaner = new PdfCleanUpProcessor(cleanUpLocations, stamper);   
cleaner.cleanUp();

stamper.close();
reader.close();

但是，在输出文件中，所有这些粗体文本的权重都变得更大，并且看起来模糊.同时，所有普通文本仍与原始文本相同.

However, in the output file, all those bold texts weight becomes heavier, and looks blurry. Meanwhile, all normal texts are still same as original.

有人知道如何解决此问题吗?

Does anyone know how to fix this problem?
