  1. Hi, I want to create a function that reads the exif orientation data of an image and rotates it as required - needs to run before before the resize function here, I'm using GD library if that is relevant: function resize_gd($sourceFileName, $folder, $destinationFileName, $newWidth, $newHeight, $keepProportion) { $newWidth = (int)$newWidth; $newHeight = (int)$newHeight; if (!$this->gdInfo >= 1 || !$this->checkGdFileType($sourceFileName)) { return false; } $img = &$this->getImg($sourceFileName); if ($this->hasError()) { return false; } $srcWidth = ImageSX($img); $srcHeight = ImageSY($img); if ( $keepProportion && ($newWidth != 0 && $srcWidth<$newWidth) && ($newHeight!=0 && $srcHeight<$newHeight) ) { if ($sourceFileName != $folder . $destinationFileName) { @copy($sourceFileName, $folder . $destinationFileName); } return true; } if ($keepProportion == true) { if ($newWidth != 0 && $newHeight != 0) { $ratioWidth = $srcWidth/$newWidth; $ratioHeight = $srcHeight/$newHeight; if ($ratioWidth < $ratioHeight) { $destWidth = $srcWidth/$ratioHeight; $destHeight = $newHeight; } else { $destWidth = $newWidth; $destHeight = $srcHeight/$ratioWidth; } } else { if ($newWidth != 0) { $ratioWidth = $srcWidth/$newWidth; $destWidth = $newWidth; $destHeight = $srcHeight/$ratioWidth; } else if ($newHeight != 0) { $ratioHeight = $srcHeight/$newHeight; $destHeight = $newHeight; $destWidth = $srcWidth/$ratioHeight; } else { $destWidth = $srcWidth; $destHeight = $srcHeight; } } } else { $destWidth = $newWidth; $destHeight = $newHeight; } $destWidth = round($destWidth); $destHeight = round($destHeight); if ($destWidth < 1) $destWidth = 1; if ($destHeight < 1) $destHeight = 1; $destImage = &$this->getImageCreate($destWidth, $destHeight);
