Merge Two Images in PHP

Merging two images with PHP

I got it working from one I made.

<?php
$dest = imagecreatefrompng('vinyl.png');
$src = imagecreatefromjpeg('cover2.jpg');

imagealphablending($dest, false);
imagesavealpha($dest, true);

imagecopymerge($dest, $src, 10, 9, 0, 0, 181, 180, 100); //have to play with these numbers for it to work for you, etc.

header('Content-Type: image/png');
imagepng($dest);

imagedestroy($dest);
imagedestroy($src);
?>

Merge two images in php

The best approach for this situation may be to create a new image in memory with the combined dimensions you desire, then copy or resample the existing images to the new image, and then save the new image to disk.

For example:

function merge($filename_x, $filename_y, $filename_result) {

 // Get dimensions for specified images

 list($width_x, $height_x) = getimagesize($filename_x);
 list($width_y, $height_y) = getimagesize($filename_y);

 // Create new image with desired dimensions

 $image = imagecreatetruecolor($width_x + $width_y, $height_x);

 // Load images and then copy to destination image

 $image_x = imagecreatefromjpeg($filename_x);
 $image_y = imagecreatefromgif($filename_y);

 imagecopy($image, $image_x, 0, 0, 0, 0, $width_x, $height_x);
 imagecopy($image, $image_y, $width_x, 0, 0, 0, $width_y, $height_y);

 // Save the resulting image to disk (as JPEG)

 imagejpeg($image, $filename_result);

 // Clean up

 imagedestroy($image);
 imagedestroy($image_x);
 imagedestroy($image_y);

}

Example:

merge('images/myimg.jpg', 'images/second.gif', 'images/merged.jpg');

PHP - Merge two images vertically using imagecopy function

When I consider the function

imagecopy ( resource $dst_im , resource$src_im , int $dst_x , int $dst_y , int $src_x , int$src_y , int $src_w , int $src_h )

It says that the dst_x and dst_y should be the x-coordinate of destination point and y-coordinate of destination point respectively.

So to merge two images vertically, it should be something like this.

imagecopy($merged_image, $img2, 0,$img1_height , 0, 0, $img2_width, $img2_height);

You should also change the $merged_width and $merged_height variable values as needed for the final result. Change the following two lines,

$merged_width = $img1_width + $img2_width; //get highest 
$merged_height = $img1_height > $img2_height ? $img1_height : $img2_height; 

As follows,

$merged_width = $img1_width > $img2_width ? $img1_width : $img2_width; //get highest width as result image width
$merged_height = $img1_height + $img2_height;

Final Result:

$img1_path = 'images/1.png';
$img2_path = 'images/2.png';

list($img1_width, $img1_height) = getimagesize($img1_path);
list($img2_width, $img2_height) = getimagesize($img2_path);

$merged_width = $img1_width > $img2_width ? $img1_width : $img2_width; //get highest width as result image width
$merged_height = $img1_height + $img2_height;

$merged_image = imagecreatetruecolor($merged_width, $merged_height);

imagealphablending($merged_image, false);
imagesavealpha($merged_image, true);

$img1 = imagecreatefrompng($img1_path);
$img2 = imagecreatefrompng($img2_path);

imagecopy($merged_image, $img1, 0, 0, 0, 0, $img1_width, $img1_height);
//place at right side of $img1
imagecopy($merged_image, $img2, 0,$img1_height , 0, 0, $img2_width, $img2_height);

//save file or output to broswer
$SAVE_AS_FILE = TRUE;
if( $SAVE_AS_FILE ){
    $save_path = "images/Sample_Output.png";
    imagepng($merged_image,$save_path);
}else{
    header('Content-Type: image/png');
    imagepng($merged_image);
}

//release memory
imagedestroy($merged_image);

How to merge multiple images and text into single image?

And i achieved it this way,

Used these 3 images, img1.png,img2.png,img3.png

And create-image.php file

 <?php
        createimageinstantly();
        //$targetFolder = '/gw/media/uploads/processed/';
        //$targetPath = $_SERVER['DOCUMENT_ROOT'] . $targetFolder;
        //$img3 = $targetPath.'img3.png';
        //print_r(getimagesize('http://www.vapor-rage.com/wp-content/uploads/2014/05/sample.jpg'));
        function createimageinstantly($img1='',$img2='',$img3=''){
            $x=$y=600;
            header('Content-Type: image/png');
            $targetFolder = '/gw/media/uploads/processed/';
            $targetPath = $_SERVER['DOCUMENT_ROOT'] . $targetFolder;

            $img1 = $targetPath.'img1.png';
            $img2 = $targetPath.'img2.png';
            $img3 = $targetPath.'img3.png';

            $outputImage = imagecreatetruecolor(600, 600);

            // set background to white
            $white = imagecolorallocate($outputImage, 255, 255, 255);
            imagefill($outputImage, 0, 0, $white);

            $first = imagecreatefrompng($img1);
            $second = imagecreatefrompng($img2);
            $third = imagecreatefrompng($img3);

            //imagecopyresized ( resource $dst_image , resource $src_image , int $dst_x , int $dst_y , int $src_x , int $src_y , int $dst_w , int $dst_h , int $src_w , int $src_h )
            imagecopyresized($outputImage,$first,0,0,0,0, $x, $y,$x,$y);
            imagecopyresized($outputImage,$second,0,0,0,0, $x, $y,$x,$y);
            imagecopyresized($outputImage,$third,200,200,0,0, 100, 100, 204, 148);

            // Add the text
            //imagettftext ( resource $image , float $size , float $angle , int $x , int $y , int $color , string $fontfile , string $text )
            //$white = imagecolorallocate($im, 255, 255, 255);
            $text = 'School Name Here';
            $font = 'OldeEnglish.ttf';
            imagettftext($outputImage, 32, 0, 150, 150, $white, $font, $text);

            $filename =$targetPath .round(microtime(true)).'.png';
            imagepng($outputImage, $filename);

            imagedestroy($outputImage);
        }
    ?>

And the result image is

Reference : imagecopyresized & imagettftext

thank you for the suggestions made via comments/answers.
And also i blogged this in detail http://sumankc.com/2016/01/30/merge-multiple-images-and-text-to-create-single-image-php-gd-library/
Good day !!

Merge two images and round corner in PHP

By cannibalising a previous answer of mine I've written the following:

<?php

$srcImg = '1.jpg';
$destImg = '2.jpg';
$dstX = 300;
$dstY = 40;
$srcX = 0;
$srcY = 0;
//$srcW = 200; // replaced with $src_width
//$srcH = 226; // replaced with $src_height
$pct = 100;

// create destination image resource.
$dest = imagecreatefromjpeg($destImg);
$dest_width = imagesx($dest);
$dest_height = imagesy($dest);

// create source image resource and define transparent colour.
$src = imagecreatefromjpeg($srcImg);
$src_width = imagesx($src);
$src_height = imagesy($src);
imagecolortransparent($src, imagecolorallocate($src, 255, 0, 255));

// create a circular mask and use it to crop the source image.
$mask = imagecreatetruecolor($src_width, $src_height);
$black = imagecolorallocate($mask, 0, 0, 0);
$magenta = imagecolorallocate($mask, 255, 0, 255);
imagefill($mask, 0, 0, $magenta);
$r = min($src_width, $src_height);
imagefilledellipse($mask, ($src_width / 2), ($src_height / 2), $r, $r, $black);
imagecolortransparent($mask, $black);
imagecopymerge($src, $mask, 0, 0, 0, 0, $src_width, $src_height, 100);
imagedestroy($mask);

// merge the two images to create the result.
imagecopymerge($dest, $src, $dstX, $dstY, $srcX, 0, $src_width, $src_height, $pct);

// output.
header('Content-type: image/jpeg');
imagejpeg($dest);
imagedestroy($src);
imagedestroy($dest);

This correctly crops the source image to a circle and merges it with the destination. You'll need to adjust the positioning to your preference.

How to merge two image in Laravel

use default php functions (imagecopymerge) ( GD library ):

<?php

list($new_width, $new_height, $new_type, $new_attr) = getimagesize("newimage.png");
switch(image_type_to_mime_type($new_type)){
     case IMAGETYPE_GIF:
         $new = imagecreatefrompng('newimage.png');
     break;
     case IMAGETYPE_JPEG:
         $new = imagecreatefromjpeg('newimage.png');
     break;
     case IMAGETYPE_PNG:
         $new = imagecreatefromgif('newimage.png');
     break;
}

$master = imagecreatefrompng('master.png');

imagealphablending($master, false);
imagesavealpha($demasterst, true);

imagecopymerge($master, $new, $box_x, $box_y, 0, 0, $box_w, $box_h, 100);
// imagecopymerge ( resource $dst_im , resource $src_im , int $dst_x , int $dst_y , int $src_x , int $src_y , int $src_w , int $src_h , int $pct )

//save image
imagepng($master, "file.png");

imagedestroy($master);
imagedestroy($new);

for jpeg format use blow function:

1. http://php.net/manual/en/function.imagejpeg.php
2. http://php.net/manual/en/function.imagecreatefromjpeg.php

If you do not want to store it and just want to send it to the user:

...
...
header('Content-Type: image/jpeg');

// Output the image
imagejpeg($master);

// Free up memory
imagedestroy($master);
imagedestroy($new);
