TYPO3 Core

In the class.t3lib_div.php function imageMagickCommand($command, $parameters, $path='') the section below is incorrect if $TYPO3_CONF_VARS['GFX']['im_useStripProfileByDefault'] = '1'

if($command=='composite' && $switchCompositeParameters) { // Because of some weird incompatibilities between ImageMagick 4 and 6 (plus GraphicsMagick), it is needed to change the parameters order under some preconditions
$paramsArr = self::unQuoteFilenames($parameters);

if(count($paramsArr)>5) {       // The mask image has been specified => swap the parameters
                                $tmp = $paramsArr[count($paramsArr)-3];
                                $paramsArr[count($paramsArr)-3] = $paramsArr[count($paramsArr)-4];
                                $paramsArr[count($paramsArr)-4] = $tmp;
                        }

$cmdLine = $path.' '.implode(' ', $paramsArr);
                }

The Strip Profile parameters are included in the count of parameters and so this is an incorrect method for testing if a mask image has been specified and it swaps the wrong parameters.

This was discovered when using the rounded_corners extension. The commands generated are constructed with $cmd = t3lib_div::imageMagickCommand('composite', '-gravity NorthEast '.$cornerNE .' '.$info³.' '.$newfile);

With $TYPO3_CONF_VARS['GFX']['im_useStripProfileByDefault'] = '1' set, the NorthEast parameter is swapped with the $cornerNE value, causing an error: gm composite: Unrecognized gravity type

localconf.php Image settings:
$TYPO3_CONF_VARS['GFX']['gdlib_png'] = '0';
$TYPO3_CONF_VARS['GFX']['im_combine_filename'] = 'composite';
$TYPO3_CONF_VARS['GFX']['im_path'] = '/usr/local/bin/';
$TYPO3_CONF_VARS['GFX']['im_path_lzw'] = '/usr/local/bin/';
$TYPO3_CONF_VARS['GFX']['im_version_5'] = 'gm';
$TYPO3_CONF_VARS['GFX']['im_imvMaskState'] = '1';
$TYPO3_CONF_VARS['GFX']['TTFdpi'] = '96';
$TYPO3_CONF_VARS['GFX']['im_useStripProfileByDefault'] = '1';

Setting $TYPO3_CONF_VARS['GFX']['im_useStripProfileByDefault'] = '0'; enables the rounded_corners extension to work correctly.
