It's possible load pdf file to QByteArray? The simple code below is not work:QFile file("/home/marcelo/Documents/test.pdf"); if (!file.open(QIODevice::ReadOnly)) { qDebug() << "file open error"; return; } QByteArray ba_pdf = file.readAll(); qDebug() << ba_pdf; file.close(); The output is: "%PDF-1.4 1 0 obj << /Title (þÿ) /Creator (þÿ) /Producer (þÿ
As you did not tell what you expected, I guess the character encoding differs, and the strings for /Creator, /Producer, ... should look different.
You might give this snippet a try:
QFile file("/home/marcelo/Documents/test.pdf");
if (!file.open(QIODevice::ReadOnly)) {
qDebug() << "file open error";
return;
}
// QByteArray ba_pdf = file.readAll();
// qDebug() << ba_pdf;
QTextStream ts(&file);
ts.setCodec ("UTF-8");
QString s_pdf = ts.readAll();
qDebug() << s_pdf;
file.close();
The "UTF-8" might need to be replaced by something else, depending on
the encoding your file uses.
