Created attachment 30971 [details] Test file When a picture is inserted into sheet that has a chart, resulting file is corrupted and causes Excel crash in my case. Code used: Workbook wb = WorkbookFactory.create(new File("Test_chart.xls")); InputStream is = new FileInputStream("project-logo.jpg"); byte[] bytes = IOUtils.toByteArray(is); int pictureIdx = wb.addPicture(bytes, Workbook.PICTURE_TYPE_JPEG); is.close(); CreationHelper helper = wb.getCreationHelper(); Sheet sheet = wb.getSheetAt(0); Drawing drawing = sheet.createDrawingPatriarch(); ClientAnchor anchor = helper.createClientAnchor(); anchor.setCol1(10); anchor.setRow1(2); anchor.setCol2(13); anchor.setRow2(8); drawing.createPicture(anchor, pictureIdx); String file = "Chart_and_picture.xls"; FileOutputStream fileOut = new FileOutputStream(file); wb.write(fileOut); fileOut.close();
From http://poi.apache.org/apidocs/org/apache/poi/ss/usermodel/Sheet.html#createDrawingPatriarch%28%29 > Note that this will normally have the effect of removing any existing drawings on this sheet. So, as documented, if you call createDrawingPatriarch on a sheet with existing drawings/charts, things will break You'll either need to ensure you only add drawings to sheets without any, or volunteer to help enhance HSSF to support fetching the existing Drawing to modify. The latter would be great for everyone, but sadly in many years no-one has thus far volunteered to help write it / pay someone else to write it :/
