Bug #66614

Updated by Markus Klein over 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.
