粗体显示后将BaseFont参数设置回默认值 [英] Setting BaseFont parameters back to default after bold

问题描述

使用iTextSharp在PDF文档中编写文本时，我使用的是绝对定位.它只能处理BaseFont，并且不能在基本字体上设置 Bold 装饰.

I am using absolute positioning when writing text in a PDF document using iTextSharp. It can only deal with BaseFont and it is not possible to set a Bold decoration on a base font.

我在一篇帖子中读到，这是将字体设置为粗体的方法:

I read in a post that this was the way to set the font to bold:

 pdfContentByte.SetCharacterSpacing(1);
 pdfContentByte.SetRGBColorFill(66, 00, 00);  
 pdfContentByte.SetLineWidth((float)0.5);                   
 pdfContentByte.SetTextRenderingMode(PdfContentByte.TEXT_RENDER_MODE_FILL_STROKE);

那行得通，但又产生了另一个问题.我不知道如何将这些参数设置回原来的默认设置(无粗体字体).

That worked but created a another problem. I don't know how to set these parameters back to my old default (none-bolded font).

你知道吗?

TIA 索伦·D.

推荐答案

答案很简单:更改状态之前，您需要保存，然后恢复添加文本后的状态:

the answer is very simple: you need to save the state before you change it, and restore the state after you've added the text:

pdfContentByte.SaveState();
pdfContentByte.SetCharacterSpacing(1);
pdfContentByte.SetRGBColorFill(66, 00, 00);  
pdfContentByte.SetLineWidth((float)0.5);                   
pdfContentByte.SetTextRenderingMode(PdfContentByte.TEXT_RENDER_MODE_FILL_STROKE);
// add the text using the changed state
pdfContentByte.RestoreState();

您对字符间距，颜色，行宽和渲染模式所做的更改仅在SaveState()和RestoreState()序列之间有效.

The changes you make to the character spacing, color, line width and rendering mode will only be valid between the SaveState() and RestoreState() sequence.
