在php中连接两个图像

如何将头部图像和身体图像结合起来，以便头部图像精确地固定在身体图像中的脖子上。

文件位于：

头像： http://yajurinfotech.com/projects/stickers/head1.gif
身体图片：http://yajurinfotech.com/projects/stickers/body2.gif

我已尝试 http://yajurinfotech.com/projects/stickers/预览.php。

我目前得到的是：

$h = 'head1.gif';
$b = 'body2.gif';

$headResource = imagecreatefromgif($h);
$bodyResource = imagecreatefromgif($b);

list($headWidth, $headHeight) = getimagesize($h);
list($bodyWidth, $bodyHeight) = getimagesize($b);

$previewHeight = $headHeight+$bodyHeight;
$previewWidth  = $headWidth;

$previewResource = imagecreatetruecolor($previewWidth, $previewHeight);

//make background white
$white = imagecolorallocate($previewResource, 255, 255, 255);
imagefill($previewResource, 0, 0, $white);

// Copy head image

imagecopyresized($previewResource,$headResource, ($headHeight/4)+3,($headHeight/2)-3,0,0,$previewWidth/4,$previewHeight/4,$headWidth,$headHeight);

//copy body image
imagecopy($previewResource,$bodyResource,0,$headHeight,0,0,$bodyWidth,$bodyHeight);

header('Content-type: image/gif');
imagegif($previewResource);

正如您在 preview.php 中看到的，头部图像没有正确放置在身体图像上。

谁能帮我找到一种适用于 body2.gif 和 body1.gif 的算法？

How can I join a head image and body image so that the head image is precisely fixed over the neck in body image.

Files are at:

Head Image: http://yajurinfotech.com/projects/stickers/head1.gif
Body Image: http://yajurinfotech.com/projects/stickers/body2.gif

I have made an attempt at http://yajurinfotech.com/projects/stickers/preview.php.

What I've got at present is:

$h = 'head1.gif';
$b = 'body2.gif';

$headResource = imagecreatefromgif($h);
$bodyResource = imagecreatefromgif($b);

list($headWidth, $headHeight) = getimagesize($h);
list($bodyWidth, $bodyHeight) = getimagesize($b);

$previewHeight = $headHeight+$bodyHeight;
$previewWidth  = $headWidth;

$previewResource = imagecreatetruecolor($previewWidth, $previewHeight);

//make background white
$white = imagecolorallocate($previewResource, 255, 255, 255);
imagefill($previewResource, 0, 0, $white);

// Copy head image

imagecopyresized($previewResource,$headResource, ($headHeight/4)+3,($headHeight/2)-3,0,0,$previewWidth/4,$previewHeight/4,$headWidth,$headHeight);

//copy body image
imagecopy($previewResource,$bodyResource,0,$headHeight,0,0,$bodyWidth,$bodyHeight);

header('Content-type: image/gif');
imagegif($previewResource);

As you can see in preview.php, head image is not placed correctly over the body image.

Can anyone help me find an algorithm that works for both body2.gif and body1.gif?

您可以使用另一种方法来执行此操作，即使用图像叠加，因此您需要有一个canevas（基本图像），并且您可以在其上添加另一张图片..

示例：

$background = imagecreatefromjpeg($_SERVER['DOCUMENT_ROOT']. base_path()."/files/polaroid.jpg");
$insert     = imagecreatefromjpeg($path. 'photos/'.$imgName);
imagecolortransparent($insert, imagecolorat($insert, 0, 0));
$insert_x = imagesx($insert);
$insert_y = imagesy($insert);
imagecopymerge($background, $insert, 39, 32, 0, 0, $insert_x, $insert_y, 100);

希望这有帮助:)

you can use another way to do this, using image superposition, so you will need to have a canevas (base image) and you can add another picture over it ..

example :

$background = imagecreatefromjpeg($_SERVER['DOCUMENT_ROOT']. base_path()."/files/polaroid.jpg");
$insert     = imagecreatefromjpeg($path. 'photos/'.$imgName);
imagecolortransparent($insert, imagecolorat($insert, 0, 0));
$insert_x = imagesx($insert);
$insert_y = imagesy($insert);
imagecopymerge($background, $insert, 39, 32, 0, 0, $insert_x, $insert_y, 100);

hope that's helpful :)
