PHP production image thumbnail, add watermark, add font PHP website production tutorial PHP website background Production Tutorial Phpcms template system

Here is a class I provided, which encapsulates these three features:

 IMGSRC = $IMGSRC; $this->init ();} /*** initialization Operation */private function init () {//Get picture information (through the GD library method, get the basic information of the picture you want to process) $this->info = getimagesize ($this IMGSRC);//The type of image is obtained by the number of the image $this->type = Image_type_to_extension ($this->info[2], false);// Create an image in memory like our image type $fun = "imagecreatefrom{$this->type}";//Copy the picture into memory $this->image = $fun ($this->imgsrc); This->showorsavefunc = "image{$this->type}";} /*** Add fonts to pictures * @param $fontfile font file path * @param $text text content * @param $red Red component * @param $green Green component * @param $blue Blue component * @param $alpha Transparency * @param $angle Offset angle * @param $size Font size * @param distance from the left * $x @param distance from the right */public function AddFont ($y , $text, $red, $green, $blue, $alpha, $angle, $size, $x, $y) {$color = Imagecolorallocatealpha ($this->image, $red, $gre En, $blue, $alpha); Imagettftext ($this->image, $size, $angle, $x, $y, $color, $fontfile, $text);} /*** browser output Picture type */private function Setoutputheader () {Header ("Content-type:". $this->info[' mime ']);} /*** output image to browser */public functiOn Outputimagetobrowser () {$this->setoutputheader (); $this->excshoworsavefunc ($this->showorsavefunc);} /*** output or Save picture */private function Excshoworsavefunc ($type, $file = ') {if ($file = = ') {$type ($this->image);} else {$typ E ($this->image, $file);}} /*** save file to local * @param local path * @param file name */public function outputimagetostorage ($filepath, $filename) {$this Setoutputheader (); $this->excshoworsavefunc ($this->showorsavefunc, $filepath. $filename. $this->type);} /*** to add a watermark to a picture * @param $waterMarkPath watermark Image Path * @param $dst _x watermark distance from the left of the original image * @param $dst the distance from the upper side of the _y watermark * @param $pct The transparency of the watermark */publ IC function Addwatermark ($waterMarkPath, $dst _x, $dst _y, $pct) {$waterInfo = getimagesize ($waterMarkPath); $waterType = Image_type_to_extension ($waterInfo [2], false); $waterFun = "imagecreatefrom{$waterType}"; $waterMarkImage = $waterFun ($waterMarkPath);//imagecopymerge (Dst_im, Src_im, dst_x, dst_y, src_x, src_y, Src_w, Src_h, pct)//pct transparency Imagecopymerge ($this->image, $waterMarkImage, $dst _x, $dst_y, 0, 0, $waterInfo [0], $waterInfo [1], $pct); Imagedestroy ($waterMarkImage);} /*** Generate picture thumbnails * @param $mWidth the width you want to compress */public function Createthumbnail ($mWidth) {$width = $this->info[0]; $height = $thi S->info[1];if ($mWidth >= $width) {return;} $mHeight = $height * $mWidth/$width;//1. Create a true color image with a width of 300 and 200 in memory $imagethumb = Imagecreatetruecolor ($mWidth, $mHeight) //2. Core steps, copy the original image to the newly created positive color picture, and compress the//imagecopyresampled (Dst_image, Src_image, dst_x, dst_y, src_x, src_y, Dst_w, dst_ in a certain proportion) H, Src_w, Src_h) imagecopyresampled ($imageThumb, $this->image, 0, 0, 0, 0, $mWidth, $mHeight, $width, $height); $this-&G T;image = $imageThumb;} /** Destroy Picture resource */public function Destroy () {Imagedestroy ($this->image);}} ?>

Here's how to use it:

 
  AddFont ("Consola.ttf", "Raid", 0, 0, 0, 0, (), $imageHelper->addwatermark (' pic2.jpg ', 0, 0,); */$imageHel Per->createthumbnail ()//$imageHelper->outputimagetobrowser (); $imageHelper->outputimagetostorage (' ', ' Testimagehelperaddfont '); $imageHelper->destroy ();?>

The above introduces the PHP production image thumbnail, add watermark, plus font, including the production of pictures, PHP content, I hope that the PHP tutorial interested friends have helped.
