SV: [java2d] Images and Text and the Fine Print

[David Lilljegren]

Hi Knut,

 

The code below maybe can be of help. This code, which was coded by my friend Isaac Elias, prints a JTable and some text.

 

Best Regards

public int print(Graphics g, PageFormat pageFormat, int pageIndex) throws PrinterException {

 double pageHeight = pageFormat.getImageableHeight()-fontHeight-placeForDel;//leave room fot note

 double tableWidth =(double) getColumnModel().getTotalColumnWidth();
 //-----   
 double scale = 1; //both x and y
 if (tableWidth >= pageWidth)//only scale if the width is to big
  scale =  pageWidth / tableWidth;
