HOWTO create multiple images
Hi,
I followed the example http://poi.apache.org/hssf/quick-guide.html#Images
and tried to create multiple PNG or JPEG images. My config follows :-
Apache Tomcat 4.1.30
Sun JDK 1.5.0_06
POI 3.0
However, there is only one image in the output workbook file, and it is
always the last inserted image, e.g. the 3rd image if I inserted 3 images
and the 5th if I inserted 5 images. I hope someone could advise how I could
insert multiple images onto a workbook file.
Thanks a lot.

Hi,
Don't create a drawing patriarch per image. You can have only one drawing patriarch per sheet.
The code below inserts two images in a worksheet.
FileInputStream is;
File file;
byte[] bytes;
int idx;
HSSFWorkbook wb = new HSSFWorkbook();
HSSFSheet sh = wb.createSheet();
HSSFPatriarch p = sh.createDrawingPatriarch();
file = new File("tomcat.png");
bytes = new byte[(int)file.length()];
is = new FileInputStream(file);
is.read(bytes);
is.close();
idx = wb.addPicture(bytes, HSSFWorkbook.PICTURE_TYPE_PNG);
p.createPicture(new HSSFClientAnchor(0, 0, 0, 0, (short)1, 1, (short)4, 10), idx);
file = new File("clock.jpg");
bytes = new byte[(int)file.length()];
is = new FileInputStream(file);
is.read(bytes);
is.close();
idx = wb.addPicture(bytes, HSSFWorkbook.PICTURE_TYPE_JPEG);
p.createPicture(new HSSFClientAnchor(0, 0, 0, 0, (short)1, 12, (short)4, 30), idx);
FileOutputStream out = new FileOutputStream("workbook.xls");
wb.write(out);
out.close();
