Hi

I'm writting an app based in qt 4.6.1 ( not 4.6.2 yet )
and I'm having trouble when trying to load jpeg files from Qt, actually
when I query for the supported image formats in the n900 i get the following:

("bmp", "pbm", "pgm", "png", "ppm", "xbm", "xpm")

The code to query is :


qDebug() << QImageReader::supportedImageFormats();

and I'm loading the pixmap with

QByteArray data = reply->readAll();
QPixmap pix;

qDebug() << QImageReader::supportedImageFormats();

if ( pix.loadFromData(data,""))//extension_.toLatin1().data()) )
{
icon_ = QIcon(pix);
}

It works fine for pngs but not in jpeg. It works fine in the emulator of the sdk or with the same sources compiles in windows.

Do I need to do something to create a QPixmap from jpeg in the N900?

Regards

not sure how helpful this will be, but..

I found recently that when deploying a (4.6.2) qt app onto windows, to get jpeg support I needed to include an 'imageformats' subdirectory from where the qt runtime dlls directory was, with the jpeg dll in it.

I would try googling on qt, jpeg, mageformats, to see if an analogous procedure is needed for the N900.

found it. some file formats are plugins to qt,

As I'm deplotying manually the so files for Qt 4.6 i needed to deploy plugins/imageformats also to the device and export QT_PLUGIN_PATH
