QImage problem

[bluetonic]

Hi,
why my programm didn't show JPG? There is definitely wrong with my code.Can the expert help me figure it out.

Thx in advance

//@main.cpp
 
#include <QtGui/QApplication>
#include <QLabel>
 
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
 
    QImage myImage;
    myImage.load("file:///home/ipan/test.JPG");
 
    QLabel myLabel;
    myLabel.setPixmap(QPixmap::fromImage(myImage));
 
 
     myLabel.show();
 
    return a.exec();
}

//@main.cpp

#include <QtGui/QApplication>
#include <QLabel>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);

    QImage myImage;
    myImage.load("file:///home/ipan/test.JPG");

    QLabel myLabel;
    myLabel.setPixmap(QPixmap::fromImage(myImage));


     myLabel.show();

    return a.exec();
}

To copy to clipboard, switch view to plain text mode

Help for figuring it out:
Start with the obvious one: check what .load returns. "Returns true if the image was successfully loaded; otherwise returns false."

Two observations:

• You don't need a file URI for a local file, just use the path.
• QImage::load() takes a file name, not a URI (it uses QFile).
• You don't need to go via a QImage to load QPixmap from a JPEG file.

OK, that's three.

Thx mvuori and ChrisQ67.

i changed the Path to:

myImage.load("/home/ipan/test.png");

myImage.load("/home/ipan/test.png");

To copy to clipboard, switch view to plain text mode 

and it works.

You don't need to go via a QImage to load QPixmap from a JPEG file.

This is just a test programm. Actually i have to fetch "picture file" that has been loaded with QImage class and showing it in on the screen. So i actualy need this to works.

thx again guys
