使用PHP将图像放在另一个图像中 [英] Place image in another image with PHP

问题描述

我有一个图像，通过php表单动态生成文本。我有一个徽标图像的位置保存到mysql数据库的变量。有没有办法拍摄这张图片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以适合此图像区域。

I have an image on which the text is being dynamically generated via a php form. I have the location of a logo image saved to a variable from a mysql database. Is there a way to take this image and apply it to a fixed position in the image? If need be, it will have to be resized smaller to fit in this image area.

我已经有一个如下所示的脚本：

I already have a script that looks like this:

        $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);

    }
//}

任何人都有想法如何这样做 - 从指定位置获取图像并将其放在另一个图像上？谢谢！

Anyone have ideas how to do this -- get the image from the specified location and put it on the other image? Thanks!
