[SOLVED] Load jpeg image
-
Hi everyone,
I have a problem when trying to load jpeg image into my app. I copied imageformats/qjeg4.dll into my app directory and used:
@
qApp->addLibraryPath(QApplication::applicationDirPath());
qApp->addLibraryPath(QApplication::applicationDirPath() + "/imageformats");
qDebug()<<QImageReader::supportedImageFormats();
@
but the last statement return:
("bmp", "pbm", "pgm", "png", "ppm", "xbm", "xpm")I have searched this forum and saw some related topics but the solutions didn't work for me.
Could anyone help me?Thanks in advanced.

how did you build your app? If you copied the dll file on the imageformats folder, you certainly dont need these lines.

qApp->addLibraryPath(QApplication::applicationDirPath());
qApp->addLibraryPath(QApplication::applicationDirPath() + "/imageformats");

[/quote]AFAIK, you only copied qjeg4.dll which is used only for "RELEASE". If you built your app in DEBUG, it will not work. You need to copy qjegd4.dll too.

Thanks Code_ReaQtor for your help.
Finally I figured out that I used newer dlls version than the Qt version used to build my app. The problem was solved when I used the proper dlls, without any lines of the above code.

You may mark this thread as [Solved] then.
