QLabel setPixmap doesnt work

[arpspatel]

void theGui::setImageLabel(QLabel* _label, IplImage* image){
    _label->setPixmap(QPixmap::fromImage(Ipl2QImage(image)).scaled(_label->size(),Qt::KeepAspectRatio));
}

void theGui::setImageLabel(QLabel* _label, IplImage* image){
    _label->setPixmap(QPixmap::fromImage(Ipl2QImage(image)).scaled(_label->size(),Qt::KeepAspectRatio));
}

To copy to clipboard, switch view to plain text mode 

This one works fine..

void theGui::setImageLabel(QLabel* _label, QString image){
    _label->setPixmap(QPixmap(image).scaled(_label->size(),Qt::KeepAspectRatio));
}

void theGui::setImageLabel(QLabel* _label, QString image){
    _label->setPixmap(QPixmap(image).scaled(_label->size(),Qt::KeepAspectRatio));
}

To copy to clipboard, switch view to plain text mode 

This one doesnt work.. no image displayed


Can you please tell me why above one doesnt work, I tried various things like QPixmap::fromImage(QImage(image)) , but still doesnt work...

Thank you very much

Are you really sure "image" is a valid path to an image? And what format is the image? Do you have the right image plugins for that?...

[arpspatel]

"image" is a valid path, also i can load it as IplImage (OpenCV) but cant seem to use it with setPixmap, its JPG file,

Do i need plugins as this is just basic image viewing.. how do i use the plugins, do i just copy qjpeg4.dll to the app dir...

Thanks

Hi,

first make sure it is really because of the plugin. If so, see http://doc.trolltech.com/4.6/deploym...tml#qt-plugins for the location of the plugins.
