I have a better solution for solving inverted colors on php 5.3.x than posted. All the other solutions I found darkens the image or messes with the colors. See below (note: my imagick object is $jpeg) $range = $jpeg->getQuantumRange(); $php_vs_arr = preg_split("/\./", phpversion()); $php_vs = $php_vs_arr[0] . '.' . $php_vs_arr[1]; if ($jpeg->getImageColorspace() == Imagick::COLORSPACE_CMYK) { //make sure cmyk color-space is set correctly $jpeg->setImageColorspace(12); // then we add an RGB profile $icc_rgb = file_get_contents(FRAMEWORK_PATH . DS . 'color' . DS . 'AdobeRGB1998.icc'); $jpeg->profileImage('icc', $icc_rgb); unset($icc_rgb); //set color space to rgb $jpeg->setImageColorspace(13); //fix gamma, hue, saturation, brightness if($php_vs < 5.3) { //ADJUST GAMMA BY 20% for 5.2.x $jpeg->levelImage(0, 2.0, $range['quantumRangeString']); } else { //php 5.3 hack FOR INVERTED COLORS $jpeg->negateImage(false, Imagick::CHANNEL_ALL); } } $jpeg->stripImage(); //end convert to RGB=========================| ---- Server IP: 69.147.83.199 Probable Submitter: 173.45.211.130 ---- Manual Page -- http://php.net/manual/en/imagick.setimagecolorspace.php Edit -- https://master.php.net/note/edit/112426 Del: integrated -- https://master.php.net/note/delete/112426/integrated Del: useless -- https://master.php.net/note/delete/112426/useless Del: bad code -- https://master.php.net/note/delete/112426/bad+code Del: spam -- https://master.php.net/note/delete/112426/spam Del: non-english -- https://master.php.net/note/delete/112426/non-english Del: in docs -- https://master.php.net/note/delete/112426/in+docs Del: other reasons-- https://master.php.net/note/delete/112426 Reject -- https://master.php.net/note/reject/112426 Search -- https://master.php.net/manage/user-notes.php
