署名を保存しています (データベースで署名パッドColdfusion/MySQL 5.0.88を使用しており、署名を .pdf で生成している pdf に出力したいと考えていますfpdf。しかし、それを機能させることはできません...

署名は次のように保存されます。

上記を画像に変換するための署名パッド（署名から画像へ）に含まれるカスタム関数があります。そのようです：

<?php
require_once '../../signature-to-image.php';
$img = sigJsonToImage(file_get_contents('sig-output.json'));

// Output to browser
header('Content-Type: image/png');
imagepng($img);

imagedestroy($img);
>

しかし、私のfpdfページでこれを試してみると、ページ全体が壊れます（画像だけをブラウザに出力するのではなく、セルに画像を埋め込みたいからだと思います）。

私がこれをしている場合：

if( strlen($unterschrift) > 0){
    $img = sigJsonToImage( $unterschrift );
};

出力してみてください：

if ( $imgProceed == "true" ){
    $pdf->imagepng($img);
} else {
    $pdf->Cell(50,4,'',0,1);
}

私が得ているのは次のとおりです。

`Call to undefined method PDF::imagepng() `/ `strpos() expects parameter 1 to be string, resource`

誰かが私に間違っていること、またはfpdfのセルに画像を含めるために何をする必要があるかを説明できますか? 私は無知です。

ありがとう！

問題はこちら

$pdf->imagepng($img);
                 ^-------------- This should be an image path (String)

解決

$file = 'signature.png' ;
imagepng($img, $file);  
                 ^----------- Save Image to File Instead

それで

if ($imgProceed == "true") {
    $pdf->imagepng($file);
} else {
    $pdf->Cell(50, 4, '', 0, 1);
}

もともと PNG に変換するつもりだったのですが、考えれば考えるほどオーバーヘッドが大きくなりました。結局、署名パッドは、FPDF で署名を再描画するために必要なすべてを提供してくれます。

私は次のことをしました：

  // decode the signature into an array
    $sig = json_decode($signatureInJSON);

    // for each line segment
    foreach ($sig as $line) {
        $lx = $line->lx;
        $ly = $line->ly;
        $mx = $line->mx;
        $my = $line->my;
        // draw the line
        $pdf->Line($lx, $ly, $mx, $my);
    }

明らかに、署名をスケーリングし、PDF 内の必要な場所にオフセットする関数もいくつか追加しました。

それが他の誰かを助けることを願っています。
