Merging Two Images With 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');

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 !!

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);

Merging multiple images next to each other in PHP

Put imagepng outside of loop:

<?php
header('Content-Type: image/png');

$numbers = array(1, 2, 3, 4, 5, 8, 9);

shuffle($numbers);
$newid=array_slice($numbers,0,6);

$count = 0;
$dest=imagecreatetruecolor(35*6,75);
foreach($newid as $imageSrc) {

    $image = imagecreatefrompng("numbers/" . $imageSrc . ".png");
    imagecopymerge($dest, $image, (35*$count), 0, 0, 0, imagesx($image), imagesy($image), 100);
    $count++;
}
imagepng($dest);

?>
