Problems mapping an image file into QByteArray

[Dark_Tower]

Hi, I am modifying the QPrinter engine for the generation of Pdf because I want to include the original image file in the PDF and not a re-compressed copy of the image. The image written in a PDF is saved in a QByteArray compressed. The original code is the following:

QBuffer buffer(&imageData);
QImageWriter writer(&buffer, "jpeg");
writer.setQuality(94);
writer.write(img);

QBuffer buffer(&imageData);
QImageWriter writer(&buffer, "jpeg");
writer.setQuality(94);
writer.write(img);

To copy to clipboard, switch view to plain text mode 

where "img" is the QImage to write on the PDF doc and "imageData" is the QByteArray that will be fisically written in the PDF doc calling to "writeImage". Well, I want to change the code above with the following:

QFile fitxerImatge(pathImatge);
imageData = fitxerImatge.readAll();

QFile fitxerImatge(pathImatge);
imageData = fitxerImatge.readAll();

To copy to clipboard, switch view to plain text mode 

where "pathImatge" is the path to the original image file. The problem is that no images are written in the PDF doc with the second code and when I openit with Adobe Acrobat Reader it says that "There isn't enough data for the image". I've checked that the path is correct and, moreover, the original image file contains a JPEG image created with Qt. So, I don't know where's the problem. Could you suggest me something, please?

Maybe you need to open() the file first?

What a mistake Thanks a lot again wysota. Finally it runs and I'm happy because i have improved some Qt code Man, I'm going to build you a statue in my town

Send me a photo when you do. And don't forget pointy ears, I seem to have them since last week.
