How PHP uses Imagick extensions to implement merged images

This article mainly introduces PHP using Imagick Extension Implementation of the merged image method, combined with examples of PHP based on the imagick extension of the process of processing pictures of the specific steps and related operations skills, the need for friends can refer to the next

The first step:

Step1: Adjust the dimensions to 590 x 590$a = ROOT. '/' .  ' A ';//scan Directory $dira = scandir ($a); $im = new Imagick;foreach ($dirA as $item) {//Skip directories and thumbnails if ($item = = = '. ' | | $item = = = ') ' || Strstr ($item, '. db ')) {continue;} Read the picture $im->readimage ($a. '/' . $item);//Get picture width x High $geo = $im->getimagegeometry (); if ($geo [' width '] = = = 590 && $geo [' height '] = = = 590) {//Width high match, jump OVER} else {//resize to 590 x 590im->resizeimage (590, 590, gmagick::filter_undefined, 1, TRUE);} Save the picture to a different directory $im->writeimage (ROOT. '/_a/'. $item);//Release Resource $im->destroy ();}

Step Two:

Step2: Merge picture and name//scan Directory $files = Scandir (ROOT. '/_a '); $k = 0;foreach ($files as $item) {//Skip directories and thumbnails if ($item = = = '. ' | | $item = = = ') ' | | strstr ($item, '. db ') {continue ;} The width of the text picture $twidth = 570;//The high $theight of the text picture = 141;//Gets the picture name $pathinfo = PathInfo ($item); $filename = $pathinfo [' filename '];//initial Image Object $text = new imagick;//Initialize the drawing object $draw = new imagickdraw;//Set the font, here is the Microsoft Black $draw->setfont (' Font/msyh.ttf ') placed under the font of the website )///Text size $draw->setfontsize (40);//Text color $draw->setfillcolor (new Imagickpixel (' #000000 '));//Text alignment $draw-> Settextalignment (imagick::align_left);//Get text message, mainly long width, because to achieve in the picture center $ A = $text->queryfontmetrics ($draw, $filename) ;//Add Text $draw->annotation (($twidth-$a [' textWidth '])/2, $filename);//Build Image $text->newimage ($twidth, $ Theight, New Imagickpixel (' #ffffff '));//Picture Format $text->setimageformat (' png ');//Draw Picture $text->drawimage ($draw);// Create a new blank image to make the canvas $canvas = new Imagick; $canvas->newimage (570, 661, ' White '); $canvas->setimageformat (' png ');//Read picture $pic = new Imagick;$pic->readimage (ROOT. '/_a/'. $item); $pic->scaleimage (470, 470, TRUE);//merge pictures into canvas $canvas->compositeimage ($pic, Imagick::composite_over, 50, 50);//merge text into canvas $canvas->compositeimage ($text, Imagick::composite_over, 0, 520);//Save the picture to another directory $canvas-> Writeimage (ROOT. '/com_a/'. $item); $k ++;echo "{$k} files proceeded.\n";}

Step Three:

Step3: Merge every 20 to one page//scan Directory $files = Scandir (ROOT. '/com_a ');//group the picture $i = $j = 0; $group = Array (); foreach ($files as $item) {  if ($item = = = '. ' | | $item = = = ' ... ' | | strs TR ($item, '. db ')) {    continue;  }  $i + +;  $group [$j] = $item;  if ($i% = = = 0) {    $j + +;  }} $total = count ($group);//concatenation of pictures by group, A4 paper size, 4x5 combination of foreach ($group as $k = = $v) {  $canvas = new Imagick;  $canvas->newimage (2480, 3508, ' White ');  $canvas->setimageformat (' png ');  $i = $j = 0;  foreach ($v as $item) {    $im = new Imagick (ROOT. '/com_a/'. $item);    150 left margin is reserved    $x = $i * 570;    Top margin of 130    $y = + $j * 661;    $canvas->compositeimage ($im, Imagick::composite_over, $x, $y);    Every 4 rows    if (($i + 1)% 4 = = = 0) {      $i = 0;      $j + +;    } else {      $i + +;    }  }  $canvas->writeimage (ROOT. '/merge_a/'. $k. '. png ');  $c = $k + 1;  echo "Group {$c}/{$total} done.\n";}
