我有一个图像,上面的文本是通过php表单动态生成的。我将徽标图像的位置保存到mysql数据库中的一个变量中。有没有办法拍摄这个图像并将其应用到图像中的固定位置?如果需要,必须将其调整为较小的大小以适应此图像区域。
我已经有了一个看起来像这样的脚本:
$img = imagecreatefromjpeg('coupon/coupontemplate.jpg');
$textColor = imagecolorallocate($img, 0, 0, 0); // black text
//Write first the coupon title
imagefttext($img, 16, 0, 20, 34, $textColor, 'coupon/arialbd.ttf', $title);
//Then write the coupon description
imagettftextbox($img, 13, 0, 20, 45, $textColor, 'coupon/arial.ttf', $description, 440);
//If the checkbox to include logo is checked...
if ($_POST['clogo'] == 'y') {
$logo = $row['imagecompany'];
$logo_file = "../directory/memberimages/$logo";
$logo_file_type = getimagesize($logo_file);
if ($logo_file_type['mime'] == 'image/jpg') {
$logoImage = imagecreatefromjpeg($logo_file);
} else if ($logo_file_type['mime'] == 'image/gif') {
$logoImage = imagecreatefromgif($logo_file);
} else if ($logo_file_type['mime'] == 'image/png') {
$logoImage = imagecreatefrompng($logo_file);
}
}
// Output image to the browser
//header('Content-Type: image/jpeg');
//imagejpeg($img);
// Or save to file
imagejpeg($img, 'my-text.jpg');
imagedestroy($img);
}
//}
有人知道如何做到这一点吗?从指定的位置获取图像并将其放在另一张图像上?谢谢
合并图像可以这样做:引用
<?php
# If you don't know the type of image you are using as your originals.
$image = imagecreatefromstring(file_get_contents($your_original_image);
$frame = imagecreatefromstring(file_get_contents($your_frame_image));
# If you know your originals are of type PNG.
$image = imagecreatefrompng($your_original_image);
$frame = imagecreatefrompng($your_frame_image);
imagecopymerge($image, $frame, 0, 0, 0, 0, 50, 50, 100);
# Save the image to a file
imagepng($image, '/path/to/save/image.png');
# Output straight to the browser.
imagepng($image);
我认为您正在寻找imagecopyresoampled()或imagecopyresized()。
您可以使用的imagecopy
函数。快速搜索发现这篇帖子可能会帮你。

您想要的函数是imagecopy:
bool imagecopy(资源$dst_im,资源$src_im,int$dst_x,int$dst_y,int$src_x,int$src_y,int$src_w,int$src_h)
