It shows how the library + can be used to display detailed metadata from a JPEG image file. This is an explanation of some of the + commands used in the script. + </p> + + <a href="http://www.ozhiker.com/electronics/pjmt/library/list_contents.php4?filename=Example.php"> + Click here to see the script</a> + + <br> + + <br> + <br> + <br> + + <h4>Error Reporting</h4> + <p> + Although this library has been tested to be error free on a large number of images, + it is good programming to turn error reporting off, to ensure that users don't see + any error messages. This is not just cosmetic, it helps hide the details of the program + from hackers. + </p> + <pre style="color:brown"> + // Turn off Error Reporting + error_reporting ( 0 ); + </pre> + + <h4>Includes</h4> + <p>Ensure that the correct files are included:</p> + <table border=1 cellspacing=0 cellpadding=4> + <tr> + <td>JPEG.php</td> + <td>For accessing basic JPEG functions - most programs will need this</td> + </tr> + <tr> + <td>EXIF.php</td> + <td>For accessing Exchangeable Image File Format (EXIF) APP1 segments</td> + </tr> + <tr> + <td>JFIF.php</td> + <td>For accessing JPEG File Interchange Format and JFIF Extension segments</td> + </tr> + <tr> + <td>Photoshop_IRB.php</td> + <td>For accessing Photoshop IRB & IPTC-NAA IIM segments</td> + </tr> + <tr> + <td>PictureInfo.php</td> + <td>For accessing APP12 Picture Info segments</td> + </tr> + <tr> + <td>XMP.php</td> + <td>For accessing APP1 XMP / RDF / Dublin Core segments</td> + </tr> + + </table> + + <br> + <br> + + <h4>Displaying Metadata Information</h4> + + <p> + Displaying metadata in HTML format from a PHP script is very simple. For example, + the following will display any EXIF information in a JPEG image: + </p> + + <pre style="color:brown"> + echo Interpret_EXIF_to_HTML( get_EXIF_JPEG( $filename ), $filename ); + </pre> + + <br> + <br> + + <p>To display the Photoshop IRB and IPTC-NAA information, use:</p> + <pre style="color:brown"> + echo Interpret_IRB_to_HTML( get_Photoshop_IRB( get_jpeg_header_data( $filename ) ), $filename ); + </pre> + + <br> + <br> + + <p> + Note: The HTML returned from these functions is just a fragment, and requires + <HTML>, <HEAD> and <BODY> tags to be provided. + </p> + + <br> + <br> + + <h4>Writing Metadata Information</h4> + <p> + Although this is not shown in the example script, writing metadata is also very simple. For example, the following will allow + the EXIF data in an image to be modified, and written to a file called "output.jpg" : + </p> + <pre style="color:brown"> + $exif_data = get_EXIF_JPEG( $filename ); + + // Modify the $exif_data array here + + $jpeg_header_data = put_EXIF_JPEG( $exif_data, $jpeg_header_data ); + put_jpeg_header_data( $filename, "output.jpg", $jpeg_header_data ); + </pre> + + <br> + <br> + + </div> + + </body> +</html>
