Bug #66614
Updated by Markus Klein almost 9 years ago
h2. How to reproduce
* set `config.noScaleUp = 0` in TS
* add a magic image to RTE
* preview the page in FE
Result: Image broken
h2. Root cause
Setting config.noScaleUp causes this line to be executed in typo3/sysext/frontend/Classes/Page/PageGenerator.php:88
<pre>
$GLOBALS['TYPO3_CONF_VARS']['GFX']['im_noScaleUp'] = isset($GLOBALS['TSFE']->config['config']['noScaleUp'])
? '' . $GLOBALS['TSFE']->config['config']['noScaleUp']
: $GLOBALS['TYPO3_CONF_VARS']['GFX']['im_noScaleUp'];
</pre>
This makes ['GFX']['im_noScaleUp'] a *string*, while in BE (when the preview image is generated in RTE) this is only loaded from install tool, where this is a *boolean* boolean value.
This tiny difference has the effect effected, that the calculated checksums used to determine whether a processed file already exists mismatch and the already generated processed file is deleted from disk.
