如何计算TCPDF中MultiCell/writeHTMLCell的高度? [英] How to calculate the height of a MultiCell/writeHTMLCell in TCPDF?

问题描述

我尝试创建具有多个页面的PDF，并且需要预先计算每个单独元素(MultiCell)的高度，以准备分页.根据文档，那里有一些函数，例如GetCharWidth/GetStringWidth来支持我自己执行此操作，但是除了潜在的性能损失外，我可能也不会正确执行此操作.建议以更优雅的方式实现我的目标?

I try to create a PDF with multiple pages and need to calculate the height of each individual element (MultiCell) in advance to prepare for a page break. According to the documentation there are a couple of functions out there like GetCharWidth/GetStringWidth to support me in doing it on my own, but besides a potential performance lost I probably will not do it the right anyway. Suggestions to achieve my goal in a more elegant way?

我知道了:D !!!!!

I GOT it :D!!!!!

创建另一个pdf2对象

Create another pdf2 object

// pdf2 set x margin to pdf1's xmargin, but y margin to zero
// to make sure that pdf2 has identical settings, you can clone the object (after initializing the main pdf object)
$pdf2 = clone $pdf;
pdf2->addpage
pdf2->writeCell
$height = pdf2->getY()
pdf2->deletePage(pdf2->getPage())
pdf1->checkPageBreak($height);
pdf1->writeCell()
