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。

我已经有了一个如下所示的脚本:

        $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);

    }
//}

任何人都有想法如何做到这一点 - 从指定位置获取图像并将其放在另一个图像上?谢谢!

合并图像可以这样做:reference

<?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);

你想要的功能是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)
