包简介
Watermark Extension for TYPO3, adding a ViewHelper that creates watermarks.
README 文档
README
This extension adds a Fluid ViewHelper that adds a Watermark image on top of an image.
Installation
Open a command console, enter your project directory and execute the following command to download the latest stable version of this package:
$ composer require jwtue/jw_watermark
This command requires you to have Composer installed globally, as explained in the installation chapter of the Composer documentation.
Alternatively, you can install it without composer through the Typo3 extension repository.
Usage
To use the watermark viewhelper, first import the watermark ViewHelper namespace at the beginning of the fluid HTML file like this (add the second line to an existing html tag):
<html xmlns:f="http://typo3.org/ns/TYPO3/CMS/Fluid/ViewHelpers"
xmlns:jw="http://typo3.org/ns/JwTue/Watermark/ViewHelpers"
data-namespace-typo3-fluid="true">
A typical usage then would look like this:
<!-- In an embedded image -->
<jw:watermarkedImage watermarkSrc="/fileadmin/Watermark.png" watermarkOpacity="1" watermarkBackgroundColor="FFFFFF" watermarkBackgroundOpacity="0" watermarkOffset: 0, watermarkPositionVertical="bottom" src="{file.uid}" treatIdAsReference="1" />
<!-- or -->
<img src="{jw:uri.watermarkedImage(watermarkSrc: '/fileadmin/Watermark.png', watermarkOpacity: '1', watermarkBackgroundColor: 'FFFFFF', watermarkBackgroundOpacity: '0', watermarkOffset: 0, watermarkPositionVertical: 'bottom', src: file.uid, treatIdAsReference: 1)}">
<!-- In a link -->
<a title="{file.title}" data-description="{file.description}" href="{jw:uri.watermarkedImage(watermarkSrc: '/fileadmin/Watermark.png', watermarkOpacity: '1', watermarkBackgroundColor: 'FFFFFF', watermarkBackgroundOpacity: '0', watermarkOffset: 0, watermarkPositionVertical: 'bottom', src: file.uid, treatIdAsReference: 1, width: settings.media.popup.width, height: settings.media.popup.height)}">
<f:render partial="Media/Rendering/Image" arguments="{file: file, dimensions: dimensions, settings: settings}" />
</a>
This will create a link to the image with the watermark image on top of it, with the preview (rendered through a partial) remaining unchanged.
The viewhelper can be used like the f:uri.image ViewHelper documented at https://docs.typo3.org/other/typo3/view-helper-reference/master/en-us/typo3/fluid/latest/Uri/Image.html with all its arguments.
The following additional arguments can be used to add the watermark:
watermarkSrc
watermarkTreatIdAsReference
watermarkImage
The same as src, treatIdAsReference, image from the f:uri.image ViewHelper, but for the watermark image.
watermarkOpacity
Opacity value for the watermark image (0=fully transparent, 1=fully opaque)
watermarkBackgroundColor
A color hex code to set a background color of the watermark
watermarkBackgroundOpacity
Opacity for the background color of the watermark (0=fully transparent, 1=fully opaque)
watermarkPositionHorizontal
Horizontal position of the watermark in the image (left/center/right)
watermarkPositionVertical
Vertical position of the watermark in the image (top/middle/bottom)
watermarkOffset
Offset from the edge in pixels (horizontally and vertically)
watermarkOffsetRelative
If set, watermarkOffset is not interpreted as a pixel value, but as a percentage value (0-100) of the image dimensions. Possible values are width, height, long, short. They set the dimension that the relative value is based upon (width/height of the image, or the long/short side of the image).
watermarkWidth
Width of the watermark in pixels
watermarkWidthRelative
If set, watermarkWidth is not interpreted as a pixel value, but as a percentage value (0-100) of the image dimensions. Possible values are width, height, long, short. They set the dimension that the relative value is based upon (width/height of the image, or the long/short side of the image).
watermarkHeight
Height of the watermark in pixels
watermarkHeightRelative
If set, watermarkHeight is not interpreted as a pixel value, but as a percentage value (0-100) of the image dimensions. Possible values are width, height, long, short. They set the dimension that the relative value is based upon (width/height of the image, or the long/short side of the image).
Restrictions
Currently, only PNG watermarks have been tested, but JPG Watermarks may work as well. Support for SVG is unknown.
Also, the ViewHelper will only apply watermarks to JPEG images, not any other image formats.
