poi+Spire.Presentation for Java獲取導入ppt元素

最近有一個導入ppt,識別ppt內所有元素需求，翻了一些資料都沒有特別好的demo,官方文檔很官方...,所以打算自己寫一個demo。poi 4.1,因為項目里之前引入的就是4.1所以就不用最新的了,poi不支持動畫效果和保存視頻,也有可能是我沒找好方法。。官網：http://poi.apache.org/apidocs/4.1/Spire.Presentation for Java 付費插件用到了保存視頻和讀取動畫效果兩個功能官網：https://www.e-iceblue.cn/spirepresentationforjava/spire-presentation-for-java-program-guide-content-html.html

踩坑

maven下載spire.presentation包不穩定，我把它放到了私有依賴庫

因為ppt的頁面大小和網頁的大小可能不一樣,會導致位置不對,所以要先獲取比例

盡量輸出png格式圖片，鏤空圖片還沒解決

ppt和pptx是兩套處理邏輯

文字多層樣式多次處理

藝術字默認轉換為圖片

ppt格式不支持視頻、音頻

poi 沒有視頻對象 我是沒找到。。 用spire.presentation獲取的視頻

具體功能

ppt有兩種格式，ppt是2003年之前的版本，pptx是2007年之后的版本，兩種版本需要分開處理，ppt里面不能放視頻和音頻，所以ppt只處理了母版元素，文字，圖片，圖形，組合圖形，藝術字，pptx多處理了視頻和音頻。 2021-09-22 更新了ppt和pptx背景圖片和背景顏色的獲取方法
