Answer 1

即跳出的第一件事是：

$pdf->Image($file=$img, $x=null, $y=null, $w=150, $h=100, $type='jpeg', $link=''); 

接近尾聲。使用：

$pdf->Image($img, null, null, 150, 100, "jpeg", ""); 

看看這是否解決了它。

Answer 2

這可能是這一行：

$this->Image('UST-LOGO.jpg',25,10,18); 

評論該行並再次嘗試。如果它現在可以工作，你可能會弄錯路徑。我習慣使用魔術「常量」__FILE__「絕對地」指定我的所有文件。

如果UST-LOGO是因爲該文件您發佈的源相同的目錄，那麼你可以在你的代碼改成這樣：

$this->Image(dirname(__FILE__) . DIRECTORY_SEPARATOR . 'UST-LOGO.jpg',25,10,18); 

---

編輯：這裏是代碼從這就引起該錯誤的FPDF類：

// line 1199 
$a=GetImageSize($file); 
if(!$a) 
    $this->Error('Missing or incorrect image file: '.$file); 

誤差只能由文件引起的或者不存在的（路徑是錯誤的）或無法讀取圖像數據（該文件已損壞或文件權限阻止它）

我建議在你的代碼（或FPDF代碼）檢查file_exists($file)添加一行。如果返回false，那麼仔細看看你的目錄（在服務器上！）。如果這返回true，那麼也許嘗試替換另一個圖像，看看是否有效。
