在这里，我有一些Excel文件，我想将包含形状的图纸转换为图像。但不幸的是，没有接口支持这种功能。图像的形状不同，它们是矢量，我只能得到一些有关文本或数学的信息。我无法获取它们的字节值，也无法在图像或HTML文件中呈现它们。如果我将excel转换为pdf，形状将受到不同程度的损坏。我已经尝试了近一个月，并进行了大量搜索。但是没有什么可以满足这样的要求。
我该怎么做才能做到？
这是寻求帮助的代码。
@SuppressWarnings("unchecked")
public static void xlsToImage(HSSFSheet sheet,String userAccount) {
HSSFPatriarch hp = sheet.getDrawingPatriarch();
List<HSSFShape> shapes = hp.getChildren();
if(shapes.size() > 0) {// I need help from here.
for(HSSFShape hssfShape : shapes)
{
hssfShape.getAnchor().getDx1();
}
}
}
这是将excel文件转换为pdf文件的代码。
