Hi Christian,
Thanks for your help, especially the gifbuilder hint! I ended up
having a look at typo3/show_item.php which in some cases, shows
thumbnails in the TYPO3 backend.
It showed me that it used t3lib_stdGraphic, and I was able to strip
out the code for generating thumbnails, which I will like to share
below:
$this->stdGraphic = t3lib_div::makeInstance('t3lib_stdGraphic');
$this->stdGraphic->init();
$this->stdGraphic->absPrefix = PATH_site;
$imageInfo = $this->stdGraphic->imageMagickConvert(
PATH_site . 'uploads/tx_templavoila/' . $templateObject['previewicon'],
'web',
'200m',
'200m',
'',
'',
'',
1
);
$imageInfo[3] = '/' . str_replace(PATH_site, '', $imageInfo[3]);
$this->content .= $this->stdGraphic->imgTag($imageInfo);
Documentation for the imageMagickConvert function can be found here:
http://doxygen.frozenkiwi.net/typo3/html/d4/d55/classt3lib__stdGraphic.html#a55f09814b58a8e995965cd665a6eafe6
Once again, thanks - and I hope, that somebody else can use this aswell! :)
Best regards,
