How to support GIF, JPEG, and other formats in QTE

1. When configuring QTE in/configure, you must add the following parameters:-QT-GIF-QT-libjpeg.
2. After the installation is complete, the installation directory contains dynamic library files such as libqgif. So and libqjpeg. So.
3. create the plug-in directory plugins/imageformats (for example,/usr/lib/plugins/imageformats) in a directory on the target board, and then set libqgif. so, libqjpeg. so and other files.
4. In the QT application, add the code qapplication: addlibrarypath ("/usr/lib/plugins") at the beginning of the main function ");
5. Done!

[Appendix]: A simple application reference
Create a qt4 empty project, add the main. cpp file, enter the following code in the main. cpp file, and compile and run the project to display the GIF animation.

# Include <qtcore>
# Include <qtgui>

Int main (INT argc, char * argv [])
{
Qapplication: addlibrarypath ("/usr/lib/plugins ");
Qapplication app (argc, argv );

Qlabel label;
Qmovie movie;
Movie. setfilename ("abc.gif ");
Label. setmovie (& movie );
Movie. Start ();
Label. Show ();

Return app.exe C ();
}
