07 '4.jpg'

08 );

09 $ type = 'GIF ';

10 $ num = 200;

11 $ qian = 'new _';

12 $ path = './gif /';

13 $ is = 1;

14 // Function for generating GIF images

15get_img ($ filelist, $ type, $ num, $ qian, $ path, $ is );

16 /*

17 * get_img image merging to generate gif dynamics

18 * $ filelist: array of images to be merged

19 * $ type: type generated

20 * $ number of frames generated by num

21 * $ qian new file name prefix

22 * $ path

23 * $ is preview?

24 */

25 function get_img ($ filelist, $ type, $ num, $ qian, $ path, $ is)

26 {

27 // Initialization class

28 $ animation = new Imagick ();

29 // Set the generated format

30 $ animation-> setFormat ($ type );

31 foreach ($ filelist as $ file ){

32 $ image = new Imagick ();

33 $ image-> readImage ($ file); // merge images

34 $ animation-> addImage ($ image); // add to object

35 $ animation-> setImageDelay ($ num); // you can specify the number of frames.

36 unset ($ image); // clear images in the memory and release the memory

37}

38 // the following two lines are used for debugging. test whether a GIF image is generated

39 // header ("Content-Type: image/gif ");

40 // echo ($ animation-> getImagesBlob ());

41 // A combination of GIF file names

42 $ images = $ qian. time (). '.'. $ type;

43 // Generate a GIF image

44 $ animation-> writeImages ($ images, true );

45 // Save the GIF to the specified folder

46 copy ($ images, $ path. $ images );

47 // whether to preview

48 if ($ is)
