I am creating an rtf document with iText, it contains a table with a mixture of text and picture cells, I am having two problems: 1) I cannot seem to get an image in a cell using a byte array. See commented call to getPicture() below. 2) if I load a picture in via a url it doesn't size to fit the cell I am adding it to, is there a way to do this?
This is an example of the type of table I am trying to write to an rtf
document:
(Embedded image moved to file: pic05436.pcx)
I want the image to size to fit the number of cells it is given to span
across.
Table table = null;
// get cell from the jtable
Object contents = jtable.getValueAt(r, c);
if (contents != null)
{
// get & record the span info
spanDetails =
tableModel.getCellAttribute().getSpan(r, c);
spanHeight = spanDetails[0];
spanWidth = spanDetails[1];
// ...................................
else if (contents instanceof PictureCell)
{
Image image = null;
try
{
// load an image via a url (this loads but it's too big)
image =
Image.getInstance("C:\\Documents and Settings\\VBrown\\My Documents\\My
Pictures\\cloud.jpg");
// load an image via a byte array (doesn't work)
//image =
Image.getInstance(getPicture((PictureCell)contents));
}
cell = new Cell(image);
}
table.addCell(cell);
}
}
}
doc.add(table);
private byte[] getPicture(PictureCell cell)
{
PictureHolder objPicHolder = (PictureHolder) cell.getContent();
java.awt.Image objContentAsImage = objPicHolder.getImage();
BufferedImage bufferedImage = new
BufferedImage(objContentAsImage.getWidth(null),
objContentAsImage.getHeight(null), BufferedImage.TYPE_INT_RGB);
Graphics graphics = bufferedImage.createGraphics();
ByteArrayOutputStream stream = new ByteArrayOutputStream();
graphics.drawImage(objContentAsImage, 0, 0,
objContentAsImage.getWidth(null), objContentAsImage.getHeight(null), null);
try
{
ImageIO.write(bufferedImage, "png", stream);
}
catch (Throwable e)
{
e.printStackTrace();
}
byte[] abytImage = stream.toByteArray();
return abytImage;
}
Any help would be greatly appreciated.
