前缀“图”并给出图的引用

为包含的图像添加标题时，是否可以调整前缀 Figure 的字体大小？此外，是否可以不使用标题以有意义的方式引用图片；我试过了，但没有数字归属于图片，我得到的是两个 ??。顺便说一下，我正在使用 \hypcap 包。

谢谢

在演示文稿中用数字编号或引用的图表有些奇怪，因为观众无法像在文章中那样翻阅它。但是，有些演示文稿可能会分发给观众（例如在课堂环境中，学生可以通过讲师下载演示文稿）。

这里有一个选项，使用\figcaption[*][<opt>]{<text>}可在文本中显示带有标题<text>（和前缀；带星号的版本会删除前缀）的图形标题。此外，[<opt>]还可用于调整参考文献的命名方式。以下 MWE 中的参考文献应解释可能的用法：
