Image manipulation • Important in any programming language • Essential
operations – Resizing – Creating Thumbnails – Cropping • More fun stuf – Filters and collages – Animated gifs
Image manipulation in PHP • GD • Imagick (Imagemagick) •
Wrappers
Resize Example: GD <?php header("Content-type: image/jpg"); $image = imagecreatefromjpeg('img01.jpg'); $width
= 200; $height = 200; $finalWidth = $width; $finalHeight = ($finalWidth * imagesy($image)) / imagesx($image); if ($finalHeight > $height) { $finalHeight = $height; $finalWidth = ($finalHeight * imagesx($image)) / imagesy($image); } $newimage = imagecreatetruecolor($finalWidth, $finalHeight); imagecopyresampled($newimage, $image, 0, 0, 0, 0, $finalWidth, $finalHeight, imagesx($image), imagesy($image)); echo imagejpeg($newimage);
Resize Example: Imagick <?php header("Content-type: image/jpg"); $image = new Imagick('img01.jpg');
$width = 200; $height = 200; $image->resizeImage($width, $height, IMAGICK::FILTER_LANCZOS, 1, true); echo $image->getImageBlob();
Resize Example: Imanee <?php include __DIR__ . '/vendor/autoload.php'; header("Content-type: image/jpg");
$imanee = new Imanee\Imanee('img01.jpg'); echo $imanee ->resize(300, 300) ->output();
Introducing: Imanee • Image manipulation for fun projects • Requirements
– PHP >= 5.4 – Imagick (php5-imagick) OR – GD (php5-gd)* • Installation – $ composer require imanee/imanee * the GD extension doesn't support animated gifs
Getting Started <?php include __DIR__ . '/vendor/autoload.php'; use Imanee\Imanee; header("Content-type:
image/jpg"); $imanee = new Imanee('img01.jpg'); echo $imanee ->resize(300, 300) ->output();
Basic operations: Thumbnail header("Content-type: image/jpg"); $imanee = new Imanee('img01.jpg'); echo
$imanee->thumbnail(300, 300) ->output();
Basic operations: Thumbnail w/ crop header("Content-type: image/jpg"); $imanee = new
Imanee('img01.jpg'); echo $imanee->thumbnail(300, 300, true) ->output();
Basic operations: Crop header("Content-type: image/jpg"); $imanee = new Imanee('img01.jpg'); echo
$imanee->crop(300, 300, 260, 0) ->output();
WRITING TEXT
Writing Text header("Content-type: image/jpg"); $imanee = new Imanee('img01.jpg'); echo $imanee->placeText('testing
imanee', Imanee::IM_POS_MID_CENTER) ->output();
Writing Text with custom Drawer header("Content-type: image/jpg"); $imanee = new
Imanee('img01.jpg'); $imanee->getDrawer() ->setFont('almonte_wood.ttf') ->setFontColor('yellow') ->setFontSize(100); echo $imanee->placeText('testing imanee!', Imanee::IM_POS_MID_CENTER) ->output();
FILTERS AND COLLAGES
Filters header("Content-type: image/jpg"); $imanee = new Imanee('img01.jpg'); echo $imanee->applyFilter('filter_bw') ->output();
Collages header("Content-type: image/jpg"); $imanee = new Imanee('img01.jpg'); echo $imanee ->placeImage('cat01.png',
Imanee::IM_POS_TOP_LEFT) ->placeImage('cat02.png', Imanee::IM_POS_TOP_RIGHT) ->output();
Animated Gifs header("Content-type: image/gif"); $frames = ['cat01.png', 'cat02.png', 'cat03.png', 'cat04.png'];
$imanee = new Imanee(); $imanee->addFrames($frames); echo $imanee->animate(30); $frames = ['cat01.png', 'cat02.png', 'cat03.png', 'cat04.png']; echo Imanee::arrayAnimate($frames, 30); echo Imanee::globAnimate(__DIR__ . '/*.png', 30);
