我以编程方式将图像粘贴到docx中。但结果布局不适合我。面对缺乏文件。 我需要改变图像换行(布局)。例如,我现在有这个:
但是想要这个:
UPD1 :我做的事情:遍历段落,然后通过运行并找到特定书签的特定运行。在这次运行中,我添加了图片:
XWPFPicture pic = run.addPicture(
new ByteArrayInputStream(picSource),
Document.PICTURE_TYPE_PNG,
"pic",
Units.toEMU(100),
Units.toEMU(30));
UPD2 :调查了这个课程中有趣的内容:
org.openxmlformats.schemas.drawingml.x2006.wordprocessingDrawing.CTAnchor
方法setWrapTight(CTWrapTight var1)
。可能是它。还是不知道如何将它应用到我的代码中。
UPD3 :最后我来到这里(currentRun - 用我们的图片运行):
CTWrapTight ctWrapTight = currentRun.getCTR().getDrawingList().get(0).addNewAnchor().addNewWrapTight();
CTWrapPath ctWrapPath = ctWrapTight.addNewWrapPolygon();
CTPoint2D ctStart = ctWrapPath.addNewStart();
ctStart.setX(0L);
ctStart.setY(0L);
CTPoint2D ctLineTo1 = ctWrapPath.addNewLineTo();
CTPoint2D ctLineTo2 = ctWrapPath.addNewLineTo();
CTPoint2D ctLineTo3 = ctWrapPath.addNewLineTo();
ctLineTo1.setX(21384L);
ctLineTo1.setY(20520L);
ctLineTo2.setX(21384L);
ctLineTo2.setY(0L);
ctLineTo3.setX(0L);
ctLineTo3.setY(0L);
ctWrapTight.setWrapText(STWrapText.BOTH_SIDES);
但是当我尝试打开它时,它会分解文档:

答案 0 :(得分:4)
虽然您已经找到了正确使用的类 - CTAnchor和后继者 - 但还需要考虑XML Schema definition of anchor。这表明,除了定义包装之外,还需要更多的任务元素。因此,使用org.openxmlformats.schemas.drawingml.x2006
类,您可能正在编写页面代码。我对此类问题的首选解决方案是提供XML
,其中所有需要的元素都由某些变量更新。然后可以解析此XML
以获取所需的对象。
示例:

import java.io.FileInputStream;
import java.io.InputStream;

String drawingDescr, int width, int height,
int left, int top) throws Exception {
