[英]XSLFGroupShape does not encompass its child shapes
I'm using Apache POI 3.16 (the latest version at the time of writing).我正在使用 Apache POI 3.16(撰写本文时的最新版本)。 In the following snippet, I create a XSLFGroupShape which I then use to create a bunch of child shapes:在下面的代码片段中,我创建了一个 XSLFGroupShape,然后我用它来创建一堆子形状:
XSLFGroupShape group = slide.createGroup();
XSLFAutoShape cardRect = group.createAutoShape();
cardRect.setShapeType(ShapeType.RECT);
cardRect.setAnchor(rect);
XSLFPictureShape avatarShape = group.createPicture(avatar);
// More shapes added to the group here...
The problem is the following: in the generated PowerPoint file, the group position and dimensions appear to be uninitialized (I've selected the rectangle whose content is pixelated; the whole rectangle and its content is a single XSLFGroupShape; notice the group's manipulator at the top-left corner of the slide):问题如下:在生成的 PowerPoint 文件中,组位置和尺寸似乎未初始化(我选择了内容像素化的矩形;整个矩形及其内容是单个 XSLFGroupShape;注意组的操纵器位于幻灯片的左上角):
Am I missing anything in my code?我的代码中是否缺少任何内容? Is there a way to circumvent or fix this problem?有没有办法规避或解决这个问题?
The GroupShape
needs an Anchor
and an InteriorAnchor
. GroupShape
需要一个Anchor
和一个InteriorAnchor
。 And the grouped shapes must fit into the GroupShape
.并且分组的形状必须适合GroupShape
。 The PowerPoint
GUI does managing that automatically while the user is working with groups.当用户与组一起工作时, PowerPoint
GUI 会自动进行管理。 But apache poi
needs correct settings for this since it simply writes into the file what the program says.但是apache poi
需要为此进行正确的设置,因为它只是将程序所说的内容写入文件。
Example: A group shape in width 350, height 300, left 100, top 50 and a simple shape in each of it's corners.示例:宽度为 350,高度为 300,左侧为 100,顶部为 50 的组形状和每个角的简单形状。
