That way you can keep original credit for the code, etc. Otherwise, great work, people can grab it from here! leandono on "Rounded Corners plugin (no transparent)" http://phpthumb.gxdlabs.com/forums/topic/rounded-corners-plugin-no-transparent#post-136 Mon, 16 Nov 2009 17:51:41 +0000 leandono 136@http://phpthumb.gxdlabs.com/forums/ gd_rounded.inc.php Code: <code> <?php //Based on <a href="http://911-need-code-help.blogspot.com/2009/05/generate-images-with-round-corners-on.html" rel="nofollow">http://911-need-code-help.blogspot.com/2009/05/generate-images-with-round-corners-on.html</a> //(Comments in spanish, sorry!) class GdRoundedLib { /** * Instance of GdThumb passed to this class * * @var GdThumb */ protected $parentInstance; protected $currentDimensions; protected $workingImage; protected $newImage; protected $options; public function createRounded($color_rounded = 'FFFFFF', $radio_rounded = 10, &$that) { // bring stuff from the parent class into this class... $this->parentInstance = $that; $this->currentDimensions = $this->parentInstance->getCurrentDimensions(); $this->workingImage = $this->parentInstance->getWorkingImage(); // Parametros $this->color_rounded = $color_rounded; $this->radio_rounded = $radio_rounded; $canvas_width = $this->currentDimensions['width']; $canvas_height = $this->currentDimensions['height']; // Crea una imagen de forma cuadrada $corner_image = imagecreatetruecolor($this->radio_rounded, $this->radio_rounded); // Pinta la figura de negro $clear_colour = imagecolorallocate($corner_image, 0, 0, 0); // La pinta del color que seleccionamos $solid_colour = imagecolorallocate($corner_image, hexdec(substr($this->color_rounded, 0, 2)) , hexdec(substr($this->color_rounded, 2, 2)) , hexdec(substr($this->color_rounded, 4, 2))); // Crea la transparencia imagecolortransparent($corner_image, $clear_colour); imagefill($corner_image, 0, 0, $solid_colour); // Crea un eclipse imagefilledellipse($corner_image, $this->radio_rounded, $this->radio_rounded, $this->radio_rounded * 2, $this->radio_rounded * 2, $clear_colour); // Copia y une la imagen imagecopymerge($this->workingImage, $corner_image, 0, 0, 0, 0, $this->radio_rounded, $this->radio_rounded, 100); // La da vuelta $corner_image = imagerotate($corner_image, 90, 0); // Copia y une la imagen imagecopymerge($this->workingImage, $corner_image, 0, $canvas_height - $this->radio_rounded, 0, 0, $this->radio_rounded, $this->radio_rounded, 100); // La da vuelta $corner_image = imagerotate($corner_image, 90, 0); // Copia y une la imagen imagecopymerge($this->workingImage, $corner_image, $canvas_width - $this->radio_rounded, $canvas_height - $this->radio_rounded, 0, 0, $this->radio_rounded, $this->radio_rounded, 100); // La da vuelta $corner_image = imagerotate($corner_image, 90, 0); // Copia y une la imagen imagecopymerge($this->workingImage, $corner_image, $canvas_width - $this->radio_rounded, 0, 0, 0, $this->radio_rounded, $this->radio_rounded, 100); imagedestroy( $corner_image ); // Devuelve la imagen return $that; } } $pt = PhpThumb::getInstance(); $pt->registerPlugin('GdRoundedLib', 'gd'); ?> </code> End of code Example: <code> <?php require_once '../ThumbLib.inc.php'; $color_rounded = 'E84E00'; $radio_rounded = 40; $thumb = PhpThumbFactory::create('test.jpg'); $thumb->adaptiveResize(300, 300)->createRounded($color_rounded, $radio_rounded); $thumb->show(); ?> </code> leandono on "Rounded Corners plugin (no transparent)" http://phpthumb.gxdlabs.com/forums/topic/rounded-corners-plugin-no-transparent#post-135 Mon, 16 Nov 2009 17:45:50 +0000 leandono 135@http://phpthumb.gxdlabs.com/forums/ [Alpha Version] This plugin create rounded corners.
