如何減少jasper ireport中的空白？

Question

這是我的模板：

PHP代碼：

<?php 

//Import the PhpJasperLibrary 
include_once('PhpJasperLibrary/tcpdf/tcpdf.php'); 
include_once("PhpJasperLibrary/PHPJasperXML.inc.php"); 


//database connection details 

$server="localhost"; 
$db="facility"; 
$user="root"; 
$pass="infinit"; 
$version="0.8b"; 
$pgport=5432; 
$pchartfolder="./class/pchart2"; 


//display errors should be off in the php.ini file 
ini_set('display_errors', 0); 

//setting the path to the created jrxml file 
$xml = simplexml_load_file("report_viwe_2.jrxml"); 

$PHPJasperXML = new PHPJasperXML(); 
//$PHPJasperXML->debugsql=true; 
//$PHPJasperXML->arrayParameter=array("parameter1"=>1); 
$PHPJasperXML->xml_dismantle($xml); 

$PHPJasperXML->transferDBtoArray($server,$user,$pass,$db); 
$PHPJasperXML->outpage("I"); //page output method I:standard output D:Download file 


?> 

我只是試圖打印使用PHP網頁上的碧玉報告。

問題是在網頁上打印時，第一頁將是空白，在下一頁它將顯示數據。我正在減少樂隊的高度。但還有一個額外的頁面出現..任何人都可以解決這個問題..

Answer 1

擺脫你的空樂隊。您有title,pageHeader和columnHeader已宣佈高度但尚未使用的波段。這些樂隊將出現在您的細節樂隊之前。完全刪除它們或者至少將它們的高度設置爲零。

您還有background,columnFooter,pageFooter和summary頻段爲空且可以刪除。
