Create Images with watermark in extbase - image

Question

I have a Model that stores a FileReference. And now I want to create an Image with a Watermark in the Extbase Controller. Does anybody know where I have to look for? I only found solutions with typoscript.

Answer 1

I choosed the TypoScript way and it worked pretty well.
Fluid:
<f:cObject typoscriptObjectPath="lib.tx_myext.watermarkedImage" data="{imageUid:'{image.uid}',copyright:'{image.copyright}')}'}"/>
TypoScript:
lib.tx_myext.watermarkedImage = IMAGE
lib.tx_myext.watermarkedImage {
file = GIFBUILDER
file {
XY = [10.w],[10.h]
format = jpg
10 = IMAGE
10 {
file {
import.field = imageUid
treatIdAsReference = 1
width = 1162
height = 580c
}
}
20 = BOX
20 {
color = #FFFFFF
opacity = 70
dimensions = [10.w]-[30.w]-10,[10.h]-20,[30.w]+20,[30.h]+20
}
30 = TEXT
30 {
text.data = field:copyright
fontSize = 15
fontColor = #000000
fontFile = path/to/my/font.ttf
offset = [10.w]-[30.w]-5,[10.h]-5
}
}
}
The result is an image with a white box and the copyright text on it at the right bottom corner.

Answer 2

I think the easiest way will be to use a typoscript solution. This must not be as pure typoscript, but the datastructure of the typoscript might be needed as parameter to the core functions of the GifBuilder class. TYPO3 7.6 API
The GifBuilder class is inherited from the class GraphicalFunctions which can be used also, as there are only a few additions and the main functionality is here.
The last problem are the examples in the net according this task: they are pibased and all of them end up in something like
$img = $this->cObj->IMAGE($typoScriptArray);
in modern (namespaced) notation using current API this would be:
$gifCreator = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance(\TYPO3\CMS\Core\Imaging\GifBuilder::class);
$gifCreator->init();
$theImage='';
if ($GLOBALS['TYPO3_CONF_VARS']['GFX']['gdlib']) {
$gifCreator->start($fileArray, $typoScriptArray);
$theImage = $gifCreator->gifBuild();
}
