如何如实地将RTF写入打印机 [英] How to write faithfully a RTF to a printer

问题描述

我需要了解将RTF文档(来自RTF文本框)写入打印机的规则.为了实现这一点，我一点一点地考虑了字符并确定了宽度(和Heigth).宽度乘以一个比例常数，如果超过 在边框上创建新行.

绘图代码如下所示

    e.Graphics.DrawString(dis，FontAttuale，spazzo，X-e.Graphics.MeasureString(dis，FontAttuale).Width * .17f，
                                    Y + kapk);
                               如果(dis！="")
                                    X-= e.Graphics.MeasureString(dis，FontAttuale).Width * .17f * omotetX;
                                X + = e.Graphics.MeasureString(dis，FontAttuale).Width * omotetX;

但是有时候行太长而另一些行太短:为什么?

请注意，已考虑缩进:请参见代码(X-= ...)

我感谢eveyone答复

您好molokko，

谢谢您在这里发布.

对于您的问题，您的项目是什么? Windows窗体还是WPF?更多细节会有所帮助.

根据我的搜索，这是有关"如何:保存，加载和打印RichTextBox内容".

我希望这会对您有所帮助.

最好的问候，

温迪

I need to know the rules to write a RTF document (from a richtextbox) to the printer. to achieve this I take the characters bit by bit and obteining the width (and the Heigth). The widths are multiplaied by a constant of proportionality and if they exceed the border a new line is created. 

the code for drawing is showed below

   e.Graphics.DrawString(dis, FontAttuale, spazzo, X - e.Graphics.MeasureString(dis, FontAttuale).Width * .17f,
                                    Y + kapk);
                                if (dis != " ")
                                    X -= e.Graphics.MeasureString(dis, FontAttuale).Width * .17f * omotetX;
                                X += e.Graphics.MeasureString(dis, FontAttuale).Width * omotetX;

Howhever some times the line is too long and others is too short:why? 

Note thath the indent is considered:see the code (X-=...)

I thank eveyone who reply

Hi molokko,

Thank you for posting here.

For your question, what is your project? A Windows Form or WPF? More details would be helpful.

Based on my search, here is an tutorial about "How to: Save, Load, and Print RichTextBox Content". 

I hope this would be helpful to you.

Best Regards,

Wendy
