我在一个 div 中有多个 PNG 图像，这些图像是 PNG，并根据他/她选择的自定义选项作为单个图像呈现给用户。此外，添加文本也作为其他功能启用，它允许带有文本的 div 添加到这些图像上方。

现在我想生成一个包含多个图像和文本组合的图像，同时保持文本的字体系列和大小。

例如。界面上出现的图像，图像和文字相结合。 (它设法出现在 css 定位中) 这是由下面的两张图片和文字组成的

这是我尝试拍摄的图像:create-image.php 文件

<?php
createimageinstantly();
function createimageinstantly($img1='',$img2='',$img3=''){
    $x=$y=1000;
    header('Content-Type: image/png');
    $targetFolder = '/gw/media/uploads/processed/';
    $targetPath = $_SERVER['DOCUMENT_ROOT'] . $targetFolder;

    $img1 = $targetPath.'img1.png';
    $img2 = $targetPath.'img2.png';
    $img3 = $targetPath.'img3.png';

    $outputImage = imagecreatetruecolor(1000, 1000);

    $first = imagecreatefrompng($img1);
    $second = imagecreatefrompng($img2);
    $third = imagecreatefrompng($img3);

    imagecopy($outputImage,$first,0,0,0,0, $x, $y);
    imagecopy($outputImage,$second,0,0,0,0, $x, $y);
    imagecopy($outputImage,$third,0,200,-200,0, $x, $y);

    imagepng($outputImage, $targetPath .round(microtime(true) * 1000).'.png');

    imagedestroy($outputImage);
 }
?>

但这给了我全黑的图像

此外，我需要在最终生成的图像上与文本混合

已编辑:

• jpg图片转为png

• imagecopymege 改为 imagecopy

                $outputImage = imagecreatetruecolor(600, 600);

                // set background to white
                $white = imagecolorallocate($outputImage, 255, 255, 255);
                imagefill($outputImage, 0, 0, $white);

                $first = imagecreatefrompng($img1);
                $second = imagecreatefrompng($img2);
                $third = imagecreatefrompng($img3);

                //imagecopyresized ( resource $dst_image , resource $src_image , int $dst_x , int $dst_y , int $src_x , int $src_y , int $dst_w , int $dst_h , int $src_w , int $src_h )
                imagecopyresized($outputImage,$first,0,0,0,0, $x, $y,$x,$y);
                imagecopyresized($outputImage,$second,0,0,0,0, $x, $y,$x,$y);
                imagecopyresized($outputImage,$third,200,200,0,0, 100, 100, 204, 148);

                imagepng($outputImage, $targetPath .round(microtime(true)).'.png');

                imagedestroy($outputImage);
            }
        ?>

和输出图像

最佳答案

我是这样实现的，

使用了这3张图片，img1.png,img2.png,img3.png

和create-image.php文件

 <?php
        createimageinstantly();
        //$targetFolder = '/gw/media/uploads/processed/';
        //$targetPath = $_SERVER['DOCUMENT_ROOT'] . $targetFolder;
        //$img3 = $targetPath.'img3.png';
        //print_r(getimagesize('http://www.vapor-rage.com/wp-content/uploads/2014/05/sample.jpg'));
        function createimageinstantly($img1='',$img2='',$img3=''){
            $x=$y=600;
            header('Content-Type: image/png');
            $targetFolder = '/gw/media/uploads/processed/';
            $targetPath = $_SERVER['DOCUMENT_ROOT'] . $targetFolder;

            $img1 = $targetPath.'img1.png';
            $img2 = $targetPath.'img2.png';
            $img3 = $targetPath.'img3.png';

            $outputImage = imagecreatetruecolor(600, 600);

            // set background to white
            $white = imagecolorallocate($outputImage, 255, 255, 255);
            imagefill($outputImage, 0, 0, $white);

            $first = imagecreatefrompng($img1);
            $second = imagecreatefrompng($img2);
            $third = imagecreatefrompng($img3);

            //imagecopyresized ( resource $dst_image , resource $src_image , int $dst_x , int $dst_y , int $src_x , int $src_y , int $dst_w , int $dst_h , int $src_w , int $src_h )
            imagecopyresized($outputImage,$first,0,0,0,0, $x, $y,$x,$y);
            imagecopyresized($outputImage,$second,0,0,0,0, $x, $y,$x,$y);
            imagecopyresized($outputImage,$third,200,200,0,0, 100, 100, 204, 148);

            // Add the text
            //imagettftext ( resource $image , float $size , float $angle , int $x , int $y , int $color , string $fontfile , string $text )
            //$white = imagecolorallocate($im, 255, 255, 255);
            $text = 'School Name Here';
            $font = 'OldeEnglish.ttf';
            imagettftext($outputImage, 32, 0, 150, 150, $white, $font, $text);

            $filename =$targetPath .round(microtime(true)).'.png';
            imagepng($outputImage, $filename);

            imagedestroy($outputImage);
        }
    ?>

结果图像是
