295 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.
296 Workaround: Open the file typo3/t3lib/class.t3lib_install.php, go to line 2042, make the function isPNG() 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.
297 On behalf of PHP we regret this inconvenience.

479 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.
480 There are three primary steps for you to take:
481
482 <strong>1: Basic Configuration</strong>
483 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.
484 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.
485 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.
486
487 <strong>2: Database Analyser</strong>
488 In this step you can either install a new database or update the database from any previous TYPO3 version.
489 You can also get an overview of extra/missing fields/tables in the database compared to a raw sql-file.
490 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.
491
492 <strong>3: Image Processing</strong>
493 This step is a visual guide to verify your configuration of the image processing software.
494 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.
495
496 <strong>4: All Configuration</strong>
497 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.
498
499 <strong>5: typo3temp/</strong>
500 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.

502
503 $this->message("About", "Why is this script stand-alone?", "
504 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.
505 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!

1427 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.
1428 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/\".
1429 If you use safe_mode with TYPO3, you should disable use of external programs ([BE][disable_exec_function]=1).
1430 In safe mode you must ensure that all the php-scripts and upload folders are owned by the same user.
1431
1432 <i>safe_mode_exec_dir=".ini_get("safe_mode_exec_dir")."</i>
1433 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)
1434
1435
1436 <strong>Example of safe_mode settings:</strong>
1437 Set this in the php.ini file:
1438
1439 ; Safe Mode
1440 safe_mode = On
1441 safe_mode_exec_dir = /usr/bin/
1442
1443 ...and the ImageMagick '/usr/bin/convert' will be executable.
1444 The last slash is important (..../) and you can only specify one directory.
1445
1446 <strong>Notice: </strong>
1447 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.

2464 TYPO3 is known for its ability to process images on the server.
2465 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).
2466 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).
2467 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.
2468
2469 In order to do this, TYPO3 uses two sets of tools:
2470
2471 <B>ImageMagick:</B>
2472 For conversion of non-web formats to webformats, combining images with alpha-masks, performing image-effects like blurring and sharpening.
2473 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).
2474 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).
2475 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])
2476 ImageMagick homepage is at ".$this->linkIt("http://www.imagemagick.org/")."
2477
2478 <B>GDLib:</B>
2479 For drawing boxes and rendering text on images with truetype fonts. Also used for icons, menuitems and generally the TypoScript GIFBUILDER object is based on GDlib, but extensively utilizing ImageMagick to process intermediate results.
2480 GDLib is accessed through internal functions in PHP, so in this case, you have no safe_mode problems, but you'll need a version of PHP with GDLib compiled in. Also in order to use TrueType fonts with GDLib you'll need FreeType compiled in as well.
2481 ".$this->getGDSoftwareInfo()."

2490 The image to the right is the reference image (how it should be) and to the left the image made by your server.
2491 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.
