Overview

With this TYPO3 extension you can create responsive image maps in the backend. This extension ships an image editor that can be used to add areas and information to an image.

Examples

Example 1: Default output

Frontend output with included example TypoScript setup

Example 2: SVG Animation

In this example the focus areas are animated via SVG. The additional information are displayed next to the image with some delay.

For administrators

Installation

Install via composer

composer require blueways/bw-focuspoint-images

Include TypoScript

Enable the extension in the Extension Manager and include the static TypoScript template or manually include setup and constants.
Define your own wizard fields

There are no default fields defined! An example with working frontend output can be found here: Setup

Usage

Add the new content element “SVG Focuspoints” to any page, link a new image and start adding your focus areas.

Configuration

Setup

To configure the fields in the focus point wizard, use the following TypoScript settings. You can choose between text, textarea and select inputs in the wizard.

This example setup is used to generate the output shown in Example 1.

plugin.tx_bwfocuspointimages.settings.fields {

    name {
        title = LLL:EXT:bw_focuspoint_images/Resources/Private/Language/locallang_db.xlf:wizard.fields.name
        type = text
    }

    description {
        title = LLL:EXT:bw_focuspoint_images/Resources/Private/Language/locallang_db.xlf:wizard.fields.description
        type = textarea
    }

    color {
        title = LLL:EXT:bw_focuspoint_images/Resources/Private/Language/locallang_db.xlf:wizard.fields.color
        type = select
        options {
            red = LLL:EXT:bw_focuspoint_images/Resources/Private/Language/locallang_db.xlf:wizard.fields.color.red
            green = LLL:EXT:bw_focuspoint_images/Resources/Private/Language/locallang_db.xlf:wizard.fields.color.green
            blue = LLL:EXT:bw_focuspoint_images/Resources/Private/Language/locallang_db.xlf:wizard.fields.color.blue
        }
    }

    link {
       title = LLL:EXT:bw_focuspoint_images/Resources/Private/Language/locallang_db.xlf:wizard.fields.link
       type = link
    }

}

Attention

You need to add the TypoScript configuration to your main template at root page. In an upcoming version the configuration will be moved to PageTS.

Constants

To override templates set your own paths via constants:

plugin.tx_bwfocuspointimages {
    view {
        templateRootPath =
        partialRootPath =
        layoutRootPath =
    }
}

Tip

To use the default rendering of fluid_styled_content, set Layout and Partial path to your styles.content setting and use the Default layout in your FocuspointImage template file.

For developers

The table sys_file_references becomes extended for the field focus_points. This field is used to save the settings made in the backend editor in json format.

To use the editor in other content elements with FAL images, use the following TCA to activate the palette:

$GLOBALS['TCA']['tt_content']['types']['your_list_type']['columnsOverrides'] = [
   'assets' => [
     'config' => [
         'foreign_types' => [
             \TYPO3\CMS\Core\Resource\File::FILETYPE_IMAGE => [
                 'showitem' => 'focus_points'
             ]
         ]
      ]
   ]
];

To decode the json format and use relative points in your fluid template, use the FocuspointProcessor:

tt_content.your_custom_element {
   dataProcessing {
      10 = Blueways\BwFocuspointImages\DataProcessing\FocuspointProcessor
      10 {
         references.fieldName = assets
         as = image
      }
   }
}

Note

These snippets assume that references are done via assets column. Change this to your needs.

Todos

Possible improvements:

More frontend examples (e.g. svg animation, use of canvas element,..)
Better configuration of the custom tt_content element (e.g. template selection, further display configuration)
Configuration for link browser
