Function content
9. File analyse_status_table.php¶
This PHP file is called in an AJAX script AnalyseDeletedAndNewMedia(), which is implemented in public_private.js. The update information needed in the file is transferred from the caller by POST method.
The information in tab 4 in the “Media processing status” window (see Fig. 5.3, Fig. 5.4, and Fig. 6.1) is used to update the iminfo.xml files in each location directory.

10. Functions in file Imageresizeprocess.php¶
Depending on the value of the fourth output argument of the function dirThumbs(), i.e. the resize status, the server side PHP file is called or not in familie-vakantie.php. This file is called by means of a hidden HTML form so that arguments can be transferred by means of the POST method. Simultaneously a progress window is opened to monitor the resizing process progress. The progress update at the server side is communicated to the client side using the Server Side Event method (available from HTML-5: XMLHttpRequest object), and the communication itself makes use of JavaScript Object Notation (JSON).
The Imageresizeprocess.php file will call another PHP file for actually resizing the images (resize-images.php).
11. Functions in resize-images.php¶
With the POST method the $vakantieDir and $parent input arguments are retrieved. Then the function ResizeGalleryPictures($parent, $vakantieDir) is called. First the masterfile rproc.txt is processed and the content of the file is stored in a 2 dimensional array. The array contains information about the location sub-directories. The function will continue with generating resized images from the original images, which are located in the location sub-directories. The resized images will be placed in a newly generated subdirectory called “Resized”. An image info file will also be created in each location sub-directory (“iminfo.txt”). This “iminfo.txt” file is a comma separated file:
- Each line corresponds to 1 image or video in the web page. In HTML5 multiple video files can be used for one web video since HTML5 makes use of fallback scenario’s. If a web browser does not support a given video container format the next video file in the HTML5 video tag will be tried.
- Each line has 11 entries:
- nnnn-Image filename, where nnnn is a 4 digit leading order count string. Ordering the image files can be done alphabetically or date taken time (date taken time is guaranteed to be known: it depends on the settings of the camera),
- Original image filename,
- Date taken string (retrieved from EXIF image data),
- Data string converted to number. If there is no date taken string, an empty string is used,
- String “R” (meaning Resized) or “Private”,
- Image width of the original image or video,
- Image height of the original image or video,
- Horizontal image resolution per pixel (XResolution),
- Vertical image resolution per pixel (YResolution),
- GPS longitude coordinate (NO-LNG if not found in image),
- GPS latitude coordinate (NO-LAT if not found in image)
The resized image files have no EXIF data in their header! The resized image files have a fixed height of 1200px. The width is determined by the aspect ratio of the original file (the original image files should have a height of at least 1200px, otherwise upscaling will take place). The resized image files will have a suffix appended to the original file basename: (“-small”). Image thumb files will also be generated with a fixed height of 90px and have file suffix “-thumb” appended file basename. The generation of the resized images and the thumbs is a time consuming process and may take a while depending on the number of images and the number of location sub-directories. An XML version iminfo.xml is also introduced.
