/**
|
|
* GIFBUILDER
|
|
*
|
|
* Generating gif/png-files from TypoScript
|
|
* Used by the menu-objects and imgResource in TypoScript.
|
|
*
|
|
* This class allows for advanced rendering of images with various layers of images, text and graphical primitives.
|
|
* 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.
|
|
* 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])
|
|
* 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.
|
|
*
|
|
* Here is an example of how to use this class (from tslib_content.php, function getImgResource):
|
|
*
|
|
* $gifCreator = GeneralUtility::makeInstance(\TYPO3\CMS\Frontend\Imaging\GifBuilder::class);
|
|
* $gifCreator->init();
|
|
* $theImage='';
|
|
* if ($GLOBALS['TYPO3_CONF_VARS']['GFX']['gdlib']) {
|
|
* $gifCreator->start($fileArray, $this->data);
|
|
* $theImage = $gifCreator->gifBuild();
|
|
* }
|
|
* return $gifCreator->getImageDimensions($theImage);
