Android replace text in pdf
0
I tried to replace text in my pdf with IText library, but then I get Contents and get string from bytes. I get
0.0800 7996 instead of letters/
But val text right string.
fun manipulatePdf(src: String, dest: String) {
val reader = PdfReader(src);
val dict = reader.getPageN(1);
val obj = dict.getDirectObject(PdfName.CONTENTS);
val text = PdfTextExtractor.getTextFromPage(reader, 1);
if (obj is PRStream) {
val data = PdfReader.getStreamBytes(obj);
val string = String(data)
string.replace("number", "1")
obj.setData(string.toByteArray());
}
val stamper = PdfStamper(reader, FileOutputStream(dest));
stamper.close();
reader.close();
}

Usually text content in a PDF should be considered final. Adding some stuff is simple but removing specific parts is difficult. A dirty way would be to paint a white rectangle over the existing term and drawn the new one over it. A better way would involve the use of redaction methods which actually remove the pre-existing glyphs.
