How to merge two images and save in php at Run Time? - php

Question

i want to make a picture upload in frame and save both image and frame as a single image ,main thing is whatever the size of image in frame,it should be appear exactly same in a final resulting image after merging.
Here is part of my code:
$imgframe = $_GET['imgframe'];
$imgphoto = $_GET['imgphoto'];
$imgwidth = $_GET['imgwidth'];
$imgheight = $_GET['imgheight'];
$imgleft = substr($_GET['imgleft'],0,-2);
$imgtop = substr($_GET['imgtop'],0, -2);
$src = imagecreatefromjpeg($imgphoto);//'image.jpg'
$dest = imagecreatefrompng($imgframe);//clip_image002.png
imagealphablending($dest, false);
imagesavealpha($dest, true);
imagecopyresampled(
$dest, $src, $imgleft, $imgtop, $imgleft, $imgtop,
$imgwidth, $imgheight, $imgwidth, $imgheight
);

As per your comment below the question, you are using the wrong function.
The PHP manual page for imagecopymerge states that it copies a part of an image onto another. It states that you can specify the origin coordinates, width and height of the region to copy from the source, and the coordinates in the destination in which to place that region.
In other words, it takes a rectangular area of a given size from the source image and puts it on top of the destination, at the given location. It does NOT ask for the size of the region into which you are copying it, only the location. Therefore, it does not resize the copied region, but copies it pixel-for-pixel.
The function you actually need is imagecopyresampled, which allows you to specify the size of the destination region, and will smoothly scale the source region to fit.
EDIT
You are still having a problem because you are using the same coordinates and the same dimensions in the source and the destination parameters. Same dimensions == no resizing.
$imgframe = $_GET['imgframe'];
$imgphoto = $_GET['imgphoto'];
// I am assuming these specify the area of the imgphoto which
// should be placed in the frame?
$imgwidth = $_GET['imgwidth'];
$imgheight = $_GET['imgheight'];
$imgleft = substr($_GET['imgleft'],0,-2);
$imgtop = substr($_GET['imgtop'],0, -2);
// now you also need to get the size of the frame so that
// you can resize the photo correctly:
$frameSize = getimagesize($imgframe);
$src = imagecreatefromjpeg($imgphoto);//'image.jpg'
$dest = imagecreatefrompng($imgframe);//clip_image002.png
imagealphablending($dest, false);
imagesavealpha($dest, true);
imagecopyresampled(
$dest, $src,
0, 0, // these two specify where in the DESTINATION you want to place the source. You might want these to be offset by the width of the frame
$imgleft, $imgtop, // the origin of area of the source you want to copy
$frameSize[0], $frameSize[1], // These specify the size of the area that you want to copy IN TO (i.e., the size in the destination), again you might want to reduce these to take into account the width of the frame
$imgwidth, $imgheight // the size of the area to copy FROM
);
