Hi,
I have been trying to create a PDF document using the
iText API. I am encountering the following problem -->
1. I am using ColumnText to split the contents into
two columns per page (I am using the method -->
ct.go(), to write, where ct is the columntext object).
2. The content is a mix of text and image.
3. The problem I have is when the writer writes the
image as the first item on a page , it does not
position the image by taking its height into account.
Hence, the image sometimes ends up interfering with
the headers in the page.
Is there any way I can control the position of the
image, when it is the first item to be written to a
page?
Thanks!
The code I am using -->
Font headerPortFont =
FontFactory.getFont(FontFactory.TIMES_BOLD, 12,
Font.NORMAL);
Font titlePortFont =
FontFactory.getFont(FontFactory.TIMES_ROMAN, 12,
Font.NORMAL);
titlePortFont.setColor(Color.blue);
Font textPortFont =
FontFactory.getFont(FontFactory.TIMES_ROMAN, 10,
Font.NORMAL);
PdfContentByte cb = docWriter.getDirectContent();
ShorexNewBean shorexBean = new ShorexNewBean();
ShorexNew[] shorexSet =
shorexBean.getShorexNews(portId); //Database call
try{
ColumnText ct = new ColumnText(cb);
//float[] right = {70, 320};
//float[] left = {300, 550};
if(shorexSet != null){
ArrayList list = new ArrayList();
for(int i=0; i< shorexSet.length; i++){
String shorexTitle =
shorexSet[i].getShorexTitle();
String shorexId =
shorexSet[i].getShorexId();
String description =
shorexSet[i].getLongDescription() ==
null?"":shorexSet[i].getLongDescription();
String duration = shorexSet[i].getDuration() ==
