I am using docx4j to generate a report, I can generate it in .docx but I have problems when converting it to pdf.
Let me explain what I do, first I have a template and I have some keywords to replace, some are text, but some others are images and even tables
To search for keywords I do this:
- Code: Select all
template = WordprocessingMLPackage.load(stream);
HashMap<String, String> values = setValuesMap(route);
replacePlaceholders(template, values);
List<Object> texts = template.getMainDocumentPart().getJAXBNodesViaXPath(XPATH_TO_SELECT_TEXT_NODES, true);
for (Object obj : texts) {
List<?> objContent = getAllElementFromObject(obj, Text.class);
for (Object obj1 : objContent){
Text text = (Text) obj1;
String textValue = text.getValue();
if (textValue.contains("KEYWORD_IMAGE")){
// Clear node content
List<Object> content=((R) obj).getContent();
content.clear();
// Add image replacement
// Get a string with base 64 value from an image
String image = getBase64Image();
String imageDataBytes = image.substring(image.indexOf(",")+1);
byte[] decoded = org.apache.commons.codec.binary.Base64.decodeBase64(imageDataBytes.getBytes());
R r = newImageR(template, decoded, null, null, 0, 1, 2000);
content.add(r);
}
if (textValue.contains("KEYWORD_TABLE")){
List<Object> content=((R) obj).getContent();
content.clear();
content.addAll(createTableFromData(data.getTableData()));
}
}
}
The function to create image element is this
- Code: Select all
public static R newImageR( WordprocessingMLPackage wordMLPackage,
byte[] bytes,
String filenameHint, String altText,
int id1, int id2, long cx) throws Exception {
BinaryPartAbstractImage imagePart = BinaryPartAbstractImage.createImagePart(wordMLPackage, bytes);
Inline inline = imagePart.createImageInline( filenameHint, altText,
id1, id2, cx, false);
// Now add the inline in w:p/w:r/w:drawing
org.docx4j.wml.ObjectFactory factory = Context.getWmlObjectFactory();
org.docx4j.wml.R run = factory.createR();
org.docx4j.wml.Drawing drawing = factory.createDrawing();
run.getContent().add(drawing);
drawing.getAnchorOrInline().add(inline);
return run;
}
And functions to create table is
- Code: Select all
private List<Object> createTableFromData(Set<Data> tableData) throws Exception{
List<Object> elements = new ArrayList<Object>();
Tbl tbl = createTable();
for (Data row : tableData){
// Create new row
Tr tr = createTrData(row);
tbl.getContent().add(tr);
}
elements.add(tbl);
return elements;
}
private Tbl createTable() throws JAXBException{
String text =
"<w:tbl xmlns:w=\"http://schemas.openxmlformats.org/wordprocessingml/2006/main\">" +
"<w:tblPr>" +
"<w:tblW w:type=\"dxa\" w:w=\"8930\"/>" +
"<w:tblInd w:type=\"dxa\" w:w=\"344\"/>" +
"<w:tblBorders>" +
"<w:top w:color=\"BFBFBF\" w:space=\"0\" w:sz=\"4\" w:themeColor=\"background1\" w:themeShade=\"BF\" w:val=\"single\"/>" +
"<w:bottom w:color=\"BFBFBF\" w:space=\"0\" w:sz=\"4\" w:themeColor=\"background1\" w:themeShade=\"BF\" w:val=\"single\"/>" +
"<w:insideH w:color=\"BFBFBF\" w:space=\"0\" w:sz=\"4\" w:themeColor=\"background1\" w:themeShade=\"BF\" w:val=\"single\"/>" +
"<w:insideV w:color=\"BFBFBF\" w:space=\"0\" w:sz=\"4\" w:themeColor=\"background1\" w:themeShade=\"BF\" w:val=\"single\"/>" +
"</w:tblBorders>" +
"<w:shd w:color=\"auto\" w:fill=\"FFFFFF\" w:themeFill=\"background1\" w:val=\"clear\"/>" +
"<w:tblCellMar>" +
"<w:top w:type=\"dxa\" w:w=\"15\"/>" +
"<w:left w:type=\"dxa\" w:w=\"15\"/>" +
"<w:bottom w:type=\"dxa\" w:w=\"15\"/>" +
"<w:right w:type=\"dxa\" w:w=\"15\"/>" +
"</w:tblCellMar>" +
"<w:tblLook w:firstColumn=\"1\" w:firstRow=\"1\" w:lastColumn=\"0\" w:lastRow=\"0\" w:noHBand=\"0\" w:noVBand=\"1\" w:val=\"04A0\"/>" +
"</w:tblPr>" +
"<w:tblGrid>" +
"<w:gridCol w:w=\"3130\"/>" +
"<w:gridCol w:w=\"5800\"/>" +
"</w:tblGrid>" +
"</w:tbl>";
Tbl tbl = (Tbl)XmlUtils.unmarshalString(text);
return tbl;
}
private Tr createTrData(Data row) throws Exception{
ObjectFactory wmlObjectFactory = new ObjectFactory();
Tr tr = createTableRow(156);
Tc tc1 = createTableCell(2126);
JAXBElement<org.docx4j.wml.Tc> tcWrapped1 = wmlObjectFactory.createTrTc(tc1);
tr.getContent().add(tcWrapped1);
if (data.getTypesOfEquipment() != null && !data.getTypesOfEquipment().isEmpty()){
tc1.getContent().add(createParagrahBulletListHeader("Types of equipment"));
for (EquipmentType et : data.getTypesOfEquipment()){
tc1.getContent().add(createBulletedParagraph(et.getName()));
}
}
Tc tc2 = createTableCell(6804);
JAXBElement<org.docx4j.wml.Tc> tcWrapped2 = wmlObjectFactory.createTrTc(tc2);
tr.getContent().add( tcWrapped2);
tc2.getContent().addAll(convertStringToParagraphs(data.getComments()));
return tr;
}
I convert to pdf with this
- Code: Select all
String inputfilepath = "C:\\Users\\user\\Downloads\\SPAIN_GENERATE_TEST_2.docx";
WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage.load(new java.io.File(inputfilepath));
OutputStream os = new java.io.FileOutputStream(inputfilepath.substring(0,inputfilepath.length()-5) + ".pdf");
FOSettings foSettings = Docx4J.createFOSettings();
foSettings.setFoDumpFile(new java.io.File(inputfilepath + ".fo"));
// foSettings.setWmlPackage(template);
foSettings.setWmlPackage(wordMLPackage);
Docx4J.toFO(foSettings, os, Docx4J.FLAG_EXPORT_PREFER_XSL);
I havent added all the code but I think is enough to show what I do, with this I generate a .docx correctly, but when I try to convert it to pdf images and tables didn´t show, after some trys I find that if I open generated docx and save it as a new docx (without doing anything else to the file) and use this duplicate file to generate the pdf, now images and tables did show.
Why is this happening? What am I doing wrong?
I attach four files:
- SPAIN_GENERATE_TEST.docx (generated file from code)
- SPAIN_GENERATE_TEST.pdf (pdf generated from previous file)
- SPAIN_GENERATE_TEST_2.docx (duplicate created using Word 2010)
- SPAIN_GENERATE_TEST_2.pdf (pdf generated from duplicated file)
I unzip both .docx and I see some differents between generated docx and I see some differences, first content of [Content_Types].xml differs, generated file include references to image file that duplicate file doesn´t, also image name is changed. I think that these changes in code have some relation with the fact that duplicated file can be converted to pdf with all his parts, but I don´t know if there is a way to reproduce these behaviour using docx4j.
Can anyone help me?
Thanks a lot for your help
And thanks a lot for your work.
