290 IF THE INSTALL TOOL CRASHES...
291 The Install Tool is checking PHPs support for image formats. However certain versions of PHP (fx. 4.3.0 with bundled GD) will crash when trying to read the PNG test file. If this happens you will see a blank screen or error message.
292 Workaround: Open the file typo3/sysext/install/mod/class.tx_install.php, go to the line where the function "isPNG()" is defined and make it return "0" hardcoded. PNG is not checked anymore and the rest of the Install Tool will work as expected. The same has been known with the other image formats as well. You can use a similar method to bypass the testing if that is also a problem.
293 On behalf of PHP we regret this inconvenience.
294
295 BTW: This Install Tool will only work if cookies are accepted by your web browser. If this dialog pops up over and over again you didn\'t enable cookies.

509 Installing TYPO3 has always been a hot topic on the mailing list and forums. Therefore we've developed this tool which will help you through configuration and testing.
510 There are three primary steps for you to take:
511
512 <strong>1: Basic Configuration</strong>
513 In this step your PHP-configuration is checked. If there are any settings that will prevent TYPO3 from running correctly you'll get warnings and errors with a description of the problem.
514 You'll have to enter a database username, password and hostname. Then you can choose to create a new database or select an existing one.
515 Finally the image processing settings are entered and verified and you can choose to let the script update the configuration file, typo3conf/localconf.php with the suggested settings.
516
517 <strong>2: Database Analyser</strong>
518 In this step you can either install a new database or update the database from any previous TYPO3 version.
519 You can also get an overview of extra/missing fields/tables in the database compared to a raw sql-file.
520 The database is also verified agains your 'tables.php' configuration (\$TCA) and you can even see suggestions to entries in \$TCA or new fields in the database.
521
522 <strong>3: Update Wizard</strong>
523 Here you will find update methods taking care of changes to the TYPO3 core which are not backwards compatible.
524 It is recommended to run this wizard after every update to make sure everything will still work flawlessly.
525
526 <strong>4: Image Processing</strong>
527 This step is a visual guide to verify your configuration of the image processing software.
528 You'll be presented to a list of images that should all match in pairs. If some irregularity appears, you'll get a warning. Thus you're able to track an error before you'll discover it on your website.
529
530 <strong>5: All Configuration</strong>
531 This gives you access to any of the configuration options in the TYPO3_CONF_VARS array. Every option is also presented with a comment explaining what it does.
532
533 <strong>6: typo3temp/</strong>
534 Here you can manage the files in typo3temp/ folder in a simple manner. typo3temp/ contains temporary files, which may still be used by the website, but some may not. By searching for files with old access-dates, you can possibly manage to delete unused files rather than files still used. However if you delete a temporary file still in use, it's just regenerated as long as you make sure to clear the cache tables afterwards.

537 $this->message('About', 'Why is this script stand-alone?', "
538 You would think that this script should rather be a module in the backend and access-controlled to only admin-users from the database. But that's not how it works.
539 The reason is, that this script must not be depending on the success of the configuration of TYPO3 and whether or not there is a working database behind. Therefore the script is invoked from the backend init.php file, which allows access if the constant 'TYPO3_enterInstallScript' has been defined and is not false. That is and should be the case <i>only</i> when calling the script 'typo3/install/index.php' - this script!

1523 In safe_mode PHP is restricted in several ways. This is a good thing because it adds protection to your (and others) scripts. But it may also introduce problems. In TYPO3 this <em>may be</em> a problem in two areas: File administration and execution of external programs, in particular ImageMagick.
1524 If you just ignore this warning, you'll most likely find, that TYPO3 seems to work except from the image-generation. The problem in that case is that the external ImageMagick programs are not allowed to be executed from the regular paths like \"/usr/bin/\" or \"/usr/X11R6/bin/\".
1525 If you use safe_mode with TYPO3, you should disable use of external programs ([BE][disable_exec_function]=1).
1526 In safe mode you must ensure that all the php-scripts and upload folders are owned by the same user.
1527
1528 <i>safe_mode_exec_dir=".ini_get('safe_mode_exec_dir')."</i>
1529 If the ImageMagick utilities are located in this directory, everything is fine. Below on this page, you can see if ImageMagick is found here. If not, ask you ISP to put the three ImageMagick programs, 'convert', 'combine'/'composite' and 'identify' there (eg. with symlinks if Unix server)
1530
1531
1532 <strong>Example of safe_mode settings:</strong>
1533 Set this in the php.ini file:
1534
1535 ; Safe Mode
1536 safe_mode = On
1537 safe_mode_exec_dir = /usr/bin/
1538
1539 ...and the ImageMagick '/usr/bin/convert' will be executable.
1540 The last slash is important (..../) and you can only specify one directory.
1541
1542 <strong>Notice: </strong>
1543 ImageMagick 4.2.9 is recommended and the binaries are normally installed by RPM in /usr/X11R6/bin or by compiling in /usr/local/bin. Please look in the \"Inside TYPO3\" pdf-document for extensive information about ImageMagick issues.

2581 function checkTheImageProcessing() {
2582 $this->message('Image Processing','What is it?',"
2583 TYPO3 is known for its ability to process images on the server.
2584 In the backend interface (TBE) thumbnails are automatically generated (by ImageMagick in thumbs.php) as well as icons, menu items and pane tabs (by GDLib).
2585 In the TypoScript enabled frontend all kinds of graphical elements are processed. Typically images are scaled down to fit the pages (by ImageMagick) and menu items, graphical headers and such are generated automatically (by GDLib + ImageMagick).
2586 In addition TYPO3 is able to handle many file formats (thanks to ImageMagick), for example TIF, BMP, PCX, TGA, AI and PDF in addition to the standard web formats; JPG, GIF, PNG.
2587
2588 In order to do this, TYPO3 uses two sets of tools:
2589
2590 <strong>ImageMagick:</strong>
2591 For conversion of non-web formats to webformats, combining images with alpha-masks, performing image-effects like blurring and sharpening.
2592 ImageMagick is a collection of external programs on the server called by the exec() function in PHP. TYPO3 uses three of these, namely 'convert' (converting fileformats, scaling, effects), 'combine'/'composite' (combining images with masks) and 'identify' (returns image information).
2593 Because ImageMagick are external programs, two requirements must be met: 1) The programs must be installed on the server and working and 2) if safe_mode is enabled, the programs must be located in the folder defined by the php.ini setting, <em>safe_mode_exec_dir</em> (else they are not executed).
2594 ImageMagick is available for both Windows and Unix. The current version is 5+, but TYPO3 enthusiasts prefer an old version 4.2.9 because that version has three main advantages: It's faster in some operations, the blur-function works, the sharpen-function works. Anyway you do it, you must tell TYPO3 by configuration whether you're using version 5+ or 4.2.9. (flag: [GFX][im_version_5])
2595 ImageMagick homepage is at ".$this->linkIt('http://www.imagemagick.org/')."
2596
2597 <strong>GDLib:</strong>
2598 For drawing boxes and rendering text on images with truetype fonts. Also used for icons, menuitems and generally the TypoScript GIFBUILDER object is based on GDlib, but extensively utilizing ImageMagick to process intermediate results.
2599 GDLib is accessed through internal functions in PHP, so in this case, you have no safe_mode problems, but you'll need a version of PHP with GDLib compiled in. Also in order to use TrueType fonts with GDLib you'll need FreeType compiled in as well.

2606 This page performs image processing and displays the result. It's a thorough check that everything you've configured is working correctly.
2607 It's quite simple to verify your installation; Just look down the page, the images in pairs should look like each other. If some images are not alike, something is wrong. You may also notice warnings and errors if this tool found signs of any problems.
2608
2609 The image to the right is the reference image (how it should be) and to the left the image made by your server.
2610 The reference images are made with the classic ImageMagick install based on the 4.2.9 RPM and 5.2.3 RPM. If the version 5 flag is set, the reference images are made by the 5.2.3 RPM.
2611
2612 This test will work only if your ImageMagick/GDLib configuration allows it to. The typo3temp/ folder must be writable for all the temporary image files. They are all prefixed 'install_' so they are easy to recognize and delete afterwards.
