在iText7中是否有與iText 5的PdfSmartCopy類似的文件

Question

？如果不是，我如何在iText 7中實現相同的功能？

Answer 1

您可以設置一個PdfWriter到true的SmartMode屬性：

/** 
* Sets the smart mode. 
* <p/> 
* In smart mode when resources (such as fonts, images,...) are 
* encountered, a reference to these resources is saved 
* in a cache, so that they can be reused. 
* This requires more memory, but reduces the file size 
* of the resulting PDF document. 
*/ 
public PdfWriter setSmartMode(boolean smartMode) 

使用這種PdfWriter複製的頁面是使用PdfSmartCopy的等價物。
