I would like to create a picture in PHP with GD composed by different other pictures. For example I have 6 pictures (or more) and I would like to create ONE picture who contain these different pictures.
The Difficulty is that my final picture must have a fixed width and height (304×179), so if the different pictures are too big they must be cut. This is an example from IconFinder :
This picture is composed by 6 images, but the 3rd bird (green) is cutted, and the 4, 5 and 6 are cutted in the bottom. This is what I want, can you give me some help to write this code in PHP ?
Thanks
Create your primary image and consider it your “canvas.”
From there, use imagecopy() to copy the smaller images into the canvas image.
See this for example:
<?php
header('Content-Type: image/jpg');
$canvas = imagecreatetruecolor(304, 179);
$icon1 = imagecreatefromjpeg('icon.jpg');
$icon2 = imagecreatefromjpeg('icon2.jpg');
// ... add more source images as needed
imagecopy($canvas, $icon1, 275, 102, 0, 0, 100, 100);
imagecopy($canvas, $icon2, 0, 120, 0, 0, 100, 100);
// ... copy additional source images to the canvas as needed
imagejpeg($canvas);
?>
In my example, icon.jpg is a 100×100 image which I am placing in the canvas such that its top left corner is located at 275, 102 in the canvas, which cuts off the right side.
Edit
I adjusted the code to be more similar to what you’re doing.
Answer：
Here a none tested modify spinet from one of my scripts, hope it can be usefull:
header('Content-type: image/png');
$image = array() //Populate this array with the image paths
//Create the Letters Image Objects
foreach($image as $a){
$image['obj'][] = imageCreateFromPNG($a);
}unset($a);
$canvasW = 300;
$canvasH = 300;
//Create Canvas
$photoImage = imagecreatetruecolor($canvasW,$canvasH);
imagesavealpha($photoImage, true);
$trans_color = imagecolorallocatealpha($photoImage, 0, 0, 0, 127);
imagefill($photoImage, 0, 0, $trans_color);
//Merge Images
$Offset_y = 0;
$images_by_row = 3;
$images_rows_height = 100; // height of each image row
$counter = 0;
foreach($image['obj'] as $a){
$counter++;
$width = ceil(imagesx($a));
$height = ceil(imagesy($a));
if(!isset($offset)){ $offset = 1; }
imageComposeAlpha($photoImage, $a, $offset, $Offset_y,$width,$height);
if($offset >= 1){
$offset = $offset + $width;
}
//Check if new row next time
if($counter >= $images_by_row){
if($images_by_row%$counter){
$offset_y += $images_rows_height;
}
}
}unset($a);
imagepng($photoImage);
