PHP에서 여러 개의 이미지를 하나의 단일 이미지로 스티칭하는 방법은 무엇입니까?

Question

나는 facebook 앱에 불을 붙이고 있는데, 여러 프로필 사진을 하나의 큰 이미지로 전환해야합니다. PHP에서 가능한 방법이 있습니까?

Answer 1

http://www.php.net/manual/en/function.imagecopy.php의 예를 참조하고 imagecopy()을 여러 번 사용하십시오.

Answer 2

저는이 질문에 새로운 것이지만 이미지를 가져와 함께 결합하는 스크립트를 개발 중입니다. 현재 모든 이미지의 크기가 동일하면 작동하지만 변경 작업을하고 있으며 기고를 환영합니다. 사진 콜라주를 만들 수있는 API가

/** 
    * Image stitching function. 
    * 
    * Now operates with images of varying heights as well as widths. 
    * 
    * @param array $files 
    * An array of files. Each element is a path to the file in question. 
    * 
    * @param int $rows 
    * The number of rows the end resulting image will have. The images 
    * will be added to the new image in the order of the array divided 
    * equally in number to the rows specified here. 
    * 
    * @param int $action 
    * An integer (or static define) of the action to take on the resulting 
    * image. 
    * IMAGE_STITCH_DISPLAY - Display the item (default action). 
    * IMAGE_STITCH_SAVE - Save the image to the file system (path required). 
    * IMAGE_STITCH_RETURN - Return the resulting file pointer to the calling 
    *      function for processing there. 
    * 
    * @param string $path 
    * The path of where to save the resulting new image. 
    * 
    * @return image $image 
    * The image data that can have whatever done to it.
