28 * GIFBUILDER
29 *
30 * Generating gif/png-files from TypoScript
31 * Used by the menu-objects and imgResource in TypoScript.
32 *
33 * This class allows for advanced rendering of images with various layers of images, text and graphical primitives.
34 * The concept is known from TypoScript as "GIFBUILDER" where you can define a "numerical array" (TypoScript term as well) of "GIFBUILDER OBJECTS" (like "TEXT", "IMAGE", etc.) and they will be rendered onto an image one by one.
35 * The name "GIFBUILDER" comes from the time where GIF was the only file format supported. PNG is just as well to create today (configured with TYPO3_CONF_VARS[GFX])
36 * Not all instances of this class is truly building gif/png files by layers; You may also see the class instantiated for the purpose of using the scaling functions in the parent class.
37 *
38 * Here is an example of how to use this class (from tslib_content.php, function getImgResource):
39 *
40 * $gifCreator = GeneralUtility::makeInstance(\TYPO3\CMS\Frontend\Imaging\GifBuilder::class);
41 * $gifCreator->init();
42 * $theImage='';
43 * if ($GLOBALS['TYPO3_CONF_VARS']['GFX']['gdlib']) {
44 * $gifCreator->start($fileArray, $this->data);
45 * $theImage = $gifCreator->gifBuild();
46 * }
47 * return $gifCreator->getImageDimensions($theImage);
