Java 如何通过docx4j将图像插入xlsx

我尝试使用docx4j在xlsx文件中插入图像，但是图像的大小只有一个单元格

到目前为止，我的代码是： 以及调用的方法：

public static void addBarcode(CTDrawing drawing, BarcodeData data, String imageRelID, int col, int row) {
    org.docx4j.dml.ObjectFactory dmlObjectFactory = new org.docx4j.dml.ObjectFactory();
    org.docx4j.dml.spreadsheetdrawing.ObjectFactory dmlspreadsheetdrawingObjectFactory = new org.docx4j.dml.spreadsheetdrawing.ObjectFactory();
    // <twoCellAnchor>
    CTTwoCellAnchor twoCellAnchor = dmlspreadsheetdrawingObjectFactory.createCTTwoCellAnchor();
    twoCellAnchor.setEditAs(org.docx4j.dml.spreadsheetdrawing.STEditAs.ONE_CELL);
    drawing.getEGAnchor().add(twoCellAnchor);
    // <twoCellAnchor/from>
    CTMarker from = dmlspreadsheetdrawingObjectFactory.createCTMarker();
    twoCellAnchor.setFrom(from);
    from.setCol(col);
    from.setColOff(0);
    from.setRow(row);
    from.setRowOff(0);
    // <twoCellAnchor/to>
    CTMarker to = dmlspreadsheetdrawingObjectFactory.createCTMarker();
    twoCellAnchor.setTo(to);
    to.setCol(col);
    to.setColOff(data.width * 9525);
    to.setRow(row);
    to.setRowOff(data.height * 9525);
    // <twoCellAnchor/pic>
    CTPicture pic = dmlspreadsheetdrawingObjectFactory.createCTPicture();
    twoCellAnchor.setPic(pic);
    pic.setMacro(null);
    // <twoCellAnchor/clientData>
    CTAnchorClientData clientData = dmlspreadsheetdrawingObjectFactory.createCTAnchorClientData();
    twoCellAnchor.setClientData(clientData);

    // <twoCellAnchor/pic/nvPicPr/cNvPr/picLocks>
    CTPictureLocking picLocks = dmlObjectFactory.createCTPictureLocking();
    cNvPicPr.setPicLocks(picLocks);
    picLocks.setNoChangeAspect(true);
    // <twoCellAnchor/pic/blipFill>
    CTBlipFillProperties blipFill = dmlObjectFactory.createCTBlipFillProperties();
    pic.setBlipFill(blipFill);
    // <twoCellAnchor/pic/blipFill/blip>
    CTBlip blip = dmlObjectFactory.createCTBlip();
    blipFill.setBlip(blip);
    blip.setLink(null);
    blip.setEmbed(imageRelID);
    blip.setCstate(null); // org.docx4j.dml.STBlipCompression.NONE);

    CTStretchInfoProperties stretch = dmlObjectFactory.createCTStretchInfoProperties();
    blipFill.setStretch(stretch);
    // <twoCellAnchor/pic/blipFill/stretch/fillRect>

    stretch.setFillRect(fillRect);
    fillRect.setR(null);

    CTGeomGuideList avLst = dmlObjectFactory.createCTGeomGuideList();
    prstGeom.setAvLst(avLst);
}

我猜您已经使用docx4j webapp从示例xlsx生成了该代码，但是您需要检查xlsx xml以了解图像大小是如何确定的。如果你不能解决这个问题，就发布一个新的问题。这是一个通用的openxml、xlsx问题，而不是docx4j问题。一旦您了解了它是如何完成的，那么您就可以修改这个问题，以解决您在用docx4j表达时遇到的任何问题；导入org.docx4j.openpackaging.io.SaveToZipFile；导入org.docx4j.openpackaging.packages.SpreadsheetMLPackage；导入org.docx4j.openpackaging.parts.*；导入org.docx4j.openpackaging.parts.WordprocessingML.BinaryPartAbstractImage；导入org.docx4j.openpackaging.parts.relationships.RelationshipsPart.addPartBehavior；导入org.docx4j.relationships.Relationship；导入org.xlsx4j.sml.*；----并且使用docx4j而不是openxml
