+=============================================================
+Feature: #67663 - Introduce DataProcessor for media galleries
+=============================================================
+
+Description
+===========
+
+The logic for working with galleries and calculating the maximum asset size is done in a separate GalleryProcessor.
+The GalleryProcessor uses the files already present in the processedData array for his calculations. The FilesProcessor can be used to fetch the files.
+
+.. code-block:: typoscript
+
+ tt_content.text_media.20 = FLUIDTEMPLATE
+ tt_content.image.20 {
+ file = EXT:myextension/Resources/Private/Templates/ContentObjects/Image.html
+
+ dataProcessing {
+
+ # Process files
+ 10 = TYPO3\CMS\Frontend\DataProcessing\FilesProcessor
+
+ # Calculate gallery info
+ 20 = TYPO3\CMS\Frontend\DataProcessing\GalleryProcessor
+ 20 {
+
+ # filesProcessedDataKey :: Key in processedData array that holds the files (default: files) + stdWrap

+ # mediaOrientation :: Media orientation, see: TCA[tt_content][column][imageorient] (default: data.imageorient) + stdWrap

+

+ * This data processor will calculate rows, columns and dimensions for a gallery
+ * based on several settings and can be used for f.i. the CType "textmedia"
+ *
+ * The output will be an array which contains the rows and columns,
+ * including the file references and the calculated width and height for each media element,

+ *
+ * Example TypoScript configuration:

+ * 10 = TYPO3\CMS\Frontend\DataProcessing\GalleryProcessor
+ * 10 {
+ * filesProcessedDataKey = files
+ * mediaOrientation.field = imageorient
+ * numberOfColumns.field = imagecols

+ * maxGalleryWidth = {$styles.content.imgtext.maxW}
+ * maxGalleryWidthInText = {$styles.content.imgtext.maxWInText}
+ * as = gallery
+ * }
+ *
+ * Output example:
+ *
+ * gallery {
+ * position {
+ * horizontal = center
+ * vertical = above
+ * noWrap = FALSE
