QT Development Gadget GIF converter (use Qmovie to intercept each frame as qimage, then save as picture file with Qfile)

Recently, many kinds of GIF expressions on QQ. Every one of them is a classic. So I wanted to convert it into a static picture ... Never learned PS. So I wrote a few lines of code. Completed. The core code is as follows

Mainly with the help of the Qmovie class. File read Mode Select Qmovie::cacheall This allows you to cache all pictures. Then end the jumptoframe to toggle the picture. The loop is done.

2. void Mainwindow::getstaticphoto ()
4. {
6. if (M_gifpath = = "" | | M_savedirpath = = "")
8. return;
10. M_pmovie = new Qmovie;
12. M_pmovie->setfilename (M_gifpath);
14. M_pmovie->setcachemode (Qmovie::cacheall);
18. For (int i =0; i< m_pmovie->framecount (); ++i) {
22. M_pmovie->jumptoframe (i);
24. Qimage image = M_pmovie->currentimage ();
26. QFile file (m_savedirpath+qstring ("/%1.jpg"). Arg (i));
28. File.Open (qfile::writeonly);
30. Image.Save (&file, "JPG");
32. File.close ();
34. }
36. }
