TCPDF $ pdf->圖像插入的圖像不可見

Question

正試圖使用​​TCPDF插入圖像到PDF中，但我只是得到空白頁。這裏是我的代碼：

if ((($_FILES["file"]["type"][0] == "image/gif") 
|| ($_FILES["file"]["type"][0] == "image/jpeg") 
|| ($_FILES["file"]["type"][0] == "image/pjpeg")) 
&& ($_FILES["file"]["size"][0] < 1000001)) 


{ 
if ($_FILES["file"]["error"][0] > 0) 
{ 
$errmsg_arr[] = "Return Code: " . $_FILES["file[]"]["error"][0] . "<br />"; 
$errflag = true; 

} else 
{ 
require_once('tcpdf/config/lang/eng.php'); 
require_once('tcpdf/tcpdf.php'); 

// create new PDF document 
$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false); 

// set document information 
$pdf->SetCreator(PDF_CREATOR); 
$pdf->SetAuthor(''); 
$pdf->SetTitle('ePast Papers'); 
$pdf->SetSubject('ePast Papers Archives'); 
$pdf->SetKeywords('TCPDF, PDF, example, test, guide'); 

// set default header data 
$pdf->SetHeaderData(PDF_HEADER_LOGO, PDF_HEADER_LOGO_WIDTH, PDF_HEADER_TITLE,  PDF_HEADER_STRING); 

// set header and footer fonts 
//$pdf->setHeaderFont(Array(PDF_FONT_NAME_MAIN, '', PDF_FONT_SIZE_MAIN)); 
//$pdf->setFooterFont(Array(PDF_FONT_NAME_DATA, '', PDF_FONT_SIZE_DATA)); 

// set default monospaced font 
$pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED); 

//set margins 
$pdf->SetMargins(PDF_MARGIN_LEFT, PDF_MARGIN_TOP, PDF_MARGIN_RIGHT); 
//$pdf->SetHeaderMargin(PDF_MARGIN_HEADER); 
//$pdf->SetFooterMargin(PDF_MARGIN_FOOTER); 

//set auto page breaks 
$pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM); 

//set image scale factor 
$pdf->setImageScale(PDF_IMAGE_SCALE_RATIO); 

//set some language-dependent strings 
$pdf->setLanguageArray($l); 

// --------------------------------------------------------- 
if ($_FILES["file"]["tmp_name"][0]!='') 
{ 
// add a page 
$pdf->AddPage(); 

// set JPEG quality 
$pdf->setJPEGQuality(75); 

// Image example 
$pdf->Image($_FILES["file"]["tmp_name"][0] , 0, 0, 4, 6, '', 'http://www.tcpdf.org', '', true, 150); 
} 
if ($_FILES["file"]["tmp_name"][1] != '') 
{ 
$pdf->AddPage(); 

// set JPEG quality 
$pdf->setJPEGQuality(75); 

// Image example 
$pdf->Image($_FILES["file"]["tmp_name"][1] , 50, 50, 100 ,150, '', 'http://www.tcpdf.org', '', true, 150); 
} 

if ($_FILES["file"]["tmp_name"][2] != '') 
{ 
$pdf->AddPage(); 

// set JPEG quality 
$pdf->setJPEGQuality(75); 

// Image example 
$pdf->Image($_FILES["file"]["tmp_name"][2] , 50, 50, 100, 150, '', 'http://www.tcpdf.org', '', true, 150); 
} 

if ($_FILES["file"]["tmp_name"][3] != '') 
{ 
$pdf->AddPage(); 

// set JPEG quality 
$pdf->setJPEGQuality(75); 

// Image example 
$pdf->Image($_FILES["file"]["tmp_name"][3] , 50, 50, 100, 150, '', 'http://www.tcpdf.org', '', true, 150); 
} 

Answer 1

我想到了上述問題。對於一些未知的原因，我沒能直接通過臨時文件TCPDF，期權首次存儲文件夾中的臨時文件，然後通過新的位置TCPDF像下面

for($i=0; $i<=6; $i++){ 

    move_uploaded_file($_FILES["file"]["tmp_name"][$i], 
    "scans/" .$_FILES["file"]["name"][$i]); 



    } 
// create handle for new PDF document 

... 
require_once('tcpdf/config/lang/eng.php'); 
require_once('tcpdf/tcpdf.php'); 

// create new PDF document 
$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false); 

// set document information 
$pdf->SetCreator(PDF_CREATOR); 
$pdf->SetAuthor(''); 
$pdf->SetTitle('ePast Papers'); 
$pdf->SetSubject('ePast Papers Archives'); 
$pdf->SetKeywords('TCPDF, PDF, example, test, guide'); 

// set default header data 
//$pdf->SetHeaderData(PDF_HEADER_LOGO, PDF_HEADER_LOGO_WIDTH, PDF_HEADER_TITLE, PDF_HEADER_STRING); 

// set header and footer fonts 
//$pdf->setHeaderFont(Array(PDF_FONT_NAME_MAIN, '', PDF_FONT_SIZE_MAIN)); 
//$pdf->setFooterFont(Array(PDF_FONT_NAME_DATA, '', PDF_FONT_SIZE_DATA)); 

// set default monospaced font 
$pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED); 

//set margins 
$pdf->SetMargins(PDF_MARGIN_LEFT, PDF_MARGIN_TOP, PDF_MARGIN_RIGHT); 
//$pdf->SetHeaderMargin(PDF_MARGIN_HEADER); 
//$pdf->SetFooterMargin(PDF_MARGIN_FOOTER); 

//set auto page breaks 
$pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM); 

//set image scale factor 
$pdf->setImageScale(PDF_IMAGE_SCALE_RATIO); 

//set some language-dependent strings 
$pdf->setLanguageArray($l); 

// --------------------------------------------------------- 
if ($_FILES["file"]["tmp_name"][0]!='') 
{ 
// add a page 
$pdf->AddPage(); 

// set JPEG quality 
$pdf->setJPEGQuality(75); 

// Image example 
$pdf->Image('scans/'.$_FILES["file"]["name"][0] , 0, 0, 210, 297, '', '', '', true, 150); 
} 
if ($_FILES["file"]["tmp_name"][1] != '') 
{ 
$pdf->AddPage(); 

// set JPEG quality 
$pdf->setJPEGQuality(75); 

// Image example 
$pdf->Image('scans/'.$_FILES["file"]["name"][1] , 0, 0, 210, 297, '', '', '', true, 150); 
} 

if ($_FILES["file"]["name"][2] != '') 
{ 
$pdf->AddPage(); 

// set JPEG quality 
$pdf->setJPEGQuality(75); 

// Image example 
$pdf->Image('scans/'.$_FILES["file"]["name"][2] , 0, 0, 210, 297, '', '', '', true, 150); 
} 

if ($_FILES["file"]["tmp_name"][3] != '') 
{ 
$pdf->AddPage(); 

// set JPEG quality 
$pdf->setJPEGQuality(75); 

// Image example 
$pdf->Image('scans/'.$_FILES["file"]["name"][3] , 0, 0, 210, 297, '', '', '', true, 150); 
} 

爲線 $pdf->Image('scans/'.$_FILES["file"]["name"][0] , x position on document, y position on document, width(mm), height(mm), '', 'Link inserted image to a URL', '', true, 150);
