PHP uses JPG to generate GIF animated pictures_PHP tutorial

PHP uses the php_imagick_st-Q8.dll class library to connect JPG images to generate GIF animated images. You need to download the php_imagick_st-Q8.dll file in advance, configure the php.ini file, and enable php_imagick_st-Q8.dll. . The configuration method is as follows:

1. Place the downloaded php_imagick_st-Q8.dll file into the PHP default extension directory, which is: php/ext/ directory;

2. Open php.ini and add this line in the extension area. Be careful not to have ";" in front of it

extension=php_imagick_st-Q8.dll

　3. Restart apache or IIS.

4. The PHP function is as follows:

　01

　02//Define JPG image sequence

　03$filelist = array(

　04 '1.jpg',

　05 '2.jpg',

　06 '3.jpg',

　07 '4.jpg'

　08);

　09$type = 'gif';

　10$num = 200;

　11$qian = 'new_';

　12$path = './gif/';

　13$is = 1;

　14//Function to generate gif images

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

　16/*

　17 * get_img merges images and generates dynamic gif

　18 * $filelist Image array to be merged

　19 * $type generated type

　20 * $num Number of frames generated

　21 * $qian new file name prefix

　22 * $path maintain path

　23 * $is whether to preview

　24 */

　25function 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); //Set the number of picture frames

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

　37}

　38 //The following two lines are used for debugging to test whether a gif image is generated

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

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

　41 //Generated GIF file name combination

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

　43 //Generate 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)

　49 {

　50 echo 'Generated gif image: ' . $images . '

　;

　51 echo "

　";

　52}

　53 else

　54 {

　55 echo 'Generated gif image: ' . $images . '

　;

　56}

　57 //Delete the original saved picture

　58 unlink($images);

　59}
