在iText7中是否存在PdfSmartCopy等价物

Question

在iText 7中是否有相当于iText 5的PdfSmartCopy类？如果没有,我如何在iText 7中实现相同的功能？

Answer 1

您可以将a的SmartMode属性设置PdfWriter为true:

/**
 * 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)

使用这样的a PdfWriter来复制页面相当于使用a PdfSmartCopy.
