怎么把word格式转换为PDF格式

[weixingrong]

在linux环境下，怎么实现从word格式转换为PDF格式方法。

从JAVA直接读取EXCEL、WORD并生成PDF文件

1。操作EXCEL和WORD文件
使用JAVA从EXCEL、WORD文件中读写数据，可以使用http://jexcelapi.sourceforge.net/提供的JAVA API－Java Excel API，这里有其指南http://www.andykhan.com/jexcelapi/tutorial.html，可由此下载JAR文件http://www.andykhan.com/jexcelapi/download.html。
此API提供所有的读、写、修改、建立的功能。对于一般应用足够了。在任何支持JAVA的系统上使用。目前，JExcelApi尚不支持有关chart、graph 或者 macro的信息，但是会拷贝并保留这些信息。只支持PNG图像。

2。生成PDF文件
若从JAVA生成PDF文件，可以使用http://www.qoppa.com/提供的应用程序库jPDFWriter。jPDFWriter是一个类库，可以直接从JAVA的应用程序调用以产生PDF文件。其网站的下载文件中包含了说明和例子，有兴趣可以仔细研究。


3。把JExcelAPI和jPDFWriter结合起来，就可以在应用中直接把XLS文件转换成PDF文件。如果再结合Database，就可以直接把有关的报告数据生成XLS文件的同时生成PDF文件。

下边给出了一个例子，是针对XLS，虽然简单，但是完整，以此为基础，可以按照自己的需要展开工作了。对于WORD也是一样，所有不再另给了。

//
//Compile:
//javac -classpath .;jexcelapi/jxl.jar;jPDFWriter/jPDFWriter.jar xlsPrinter.java
//Run:
//java -classpath .;jexcelapi/jxl.jar;jPDFWriter/jPDFWriter.jar xlsPrinter
//

m_DrawGrid = drawGrid;

}

}

//主程序
public static void main (String args [])
{
xlsPrinter gridPrinter = new xlsPrinter(initData (), null, true);

PrinterJob printerJob = PDFPrinterJob.getPrinterJob();
printerJob.setPrintable(gridPrinter);

try{
printerJob.print();
}catch (PrinterException pe){
pe.printStackTrace();
}

System.exit(0);
}

//打印接口，由此生成PDF文件，此段代码来源于jPDFWriter的例子
public int print (Graphics g, PageFormat pf, int pageIndex)

int lineHeight = g.getFontMetrics().getHeight();

// gets used multiple times to print a string

}
// Need to do this because Java PrinterJob can call this
// method multiple times for the same page;
else if (m_CurrentPage == pageIndex)
{
currentRow = m_CurrentPageStartRow;
}
else
{
currentRow = m_CurrentPageEndRow + 1;
m_CurrentPageStartRow = currentRow;
}

// If we're out of lines, tell the PrinterJob we're done
if (currentRow >= m_Data.size())
{
return Printable.NO_SUCH_PAGE;
}

// Loop through lines until we fill the page
int currentY = (int)(pf.getImageableY() + lineHeight);
while (currentRow < m_Data.size() &&
currentY + lineHeight < pf.getImageableY() + pf.getImageableHeight())
{
// Draw the next line
int currentX = (int)pf.getImageableX();
Vector nextRow = (Vector)m_Data.elementAt (currentRow);
for (int col = 0; col < nextRow.size(); ++col)
{
String cellString = (String)nextRow.elementAt (col);
g.drawString (cellString, currentX + CELL_MARGIN_X, currentY + CELL_MARGIN_Y);

int colWidth = DEFAULT_COLUMN_WIDTH;
if (m_ColumnWidths != null && m_ColumnWidths.length > col)
{
colWidth = m_ColumnWidths [col];
}

// Draw grid if needed
if (m_DrawGrid)
{
g.drawRect (currentX, currentY - (lineHeight / 2), colWidth, lineHeight);
}

// Advance x
currentX += colWidth;
}

// Advance to the next line
++currentRow;
currentY += lineHeight;
}

// Save the ned line and current page
// Again, we have to do this because of multiple calls for the same page.
m_CurrentPageEndRow = currentRow;
m_CurrentPage = pageIndex;

return Printable.PAGE_EXISTS;

linux下太好转了，他有好多个读PDF的程序，OPenoffice直接就可以专的。
