中心文字收据打印 [英] Center text for receipt printing

问题描述

我有我用来打印收据从C＃某些code。

下面打印的code OK，但我挣扎对齐文本左，右和中央，

 图形显卡= e.Graphics;
字体的字体=新的字体（宋体，10）;
浮fontHeight = font.GetHeight（）;
INT STARTX = 0;
INT startY = 0;
的int偏移量= 0;

graphics.DrawString（欢迎来到MSST，新的字体（宋体，14），新SolidBrush（Color.Black），STARTX，startY +偏移量）;
偏移=偏移+ 20;

graphics.DrawString（无回执+ receptno + 1，新的字体（宋体，14），新SolidBrush（Color.Black），STARTX，startY +偏移量）;
偏移=偏移+ 20;

graphics.DrawString（日期：+ DateTime.Today，新的字体（宋体，12），新SolidBrush（Color.Black），STARTX，startY +偏移量）;
偏移=偏移+ 20;

graphics.DrawString（------------------------------------------，新字体（宋体，10），新SolidBrush（Color.Black），STARTX，startY +偏移量）;
偏移=偏移+ 20;
 

谁能帮我用文字对齐？

更新：以下是所需的输出：

欢迎MSST 收据编号：3 日期：2014年5月24日10时06分22秒 ------------------------------------------

解决方案

下面是你的榜样的全code，使用三个 StringFormats 和一个额外的行显示右对齐文本。我还增加了一个前置号码并转换一切彩车 ..我使用的是面板吸取和设置布局矩形到面板的尺寸。你应该使用，当然您的打印目标，..

  INT receptno = 42;
显卡显卡= e.Graphics;

字体font10 =新的字体（宋体，10）;
字体font12 =新的字体（宋体，12）;
字体font14 =新的字体（宋体，14）;

浮主导= 4;
浮lineheight10 = font10.GetHeight（）+龙头;
浮lineheight12 = font12.GetHeight（）+龙头;
浮lineheight14 = font14.GetHeight（）+龙头;

浮STARTX = 0;
浮startY =领先;
浮偏移量= 0;

的StringFormat formatLeft =新的StringFormat（StringFormatFlags.NoClip）;
的StringFormat formatCenter =新的StringFormat（formatLeft）;
的StringFormat formatRight =新的StringFormat（formatLeft）;

formatCenter.Alignment = StringAlignment.Center;
formatRight.Alignment = StringAlignment.Far;
formatLeft.Alignment = StringAlignment.Near;

的SizeF layoutSize =新的SizeF（yourPrintAreaWidth  - 偏移* 2，lineheight14）;
的RectangleF布局=新的RectangleF（新的PointF（STARTX，startY +偏移量），layoutSize）;

刷= Brushes.Black;

graphics.DrawString（欢迎来到MSST，font14，刷，布局，formatCenter）;
偏移=偏移+ lineheight14;
布局=新的RectangleF（新的PointF（STARTX，startY +偏移量），layoutSize）;
graphics.DrawString（无回执+ receptno + 1，font14，刷，布局，formatLeft）;
偏移=偏移+ lineheight14;
布局=新的RectangleF（新的PointF（STARTX，startY +偏移量），layoutSize）;
graphics.DrawString（日期：+ DateTime.Today，font12，刷，布局，formatLeft）;
偏移=偏移+ lineheight12;
布局=新的RectangleF（新的PointF（STARTX，startY +偏移量），layoutSize）;
graphics.DrawString（。PadRight（46，_），font10，刷，布局，formatLeft）;
偏移=偏移+ lineheight10;
布局=新的RectangleF（新的PointF（STARTX，startY +偏移量），layoutSize）;

graphics.DrawString（著作权SO，font10，刷，布局，formatRight）;
偏移=偏移+ lineheight10;

font10.Dispose（）; font12.Dispose（）; font14.Dispose（）;
 

I have some code which I'm using to print a receipt from C#.

The code below prints OK but I'm struggling with aligning the text left right and center,

Graphics graphics = e.Graphics;
Font font = new Font("Courier New", 10);
float fontHeight = font.GetHeight();
int startX = 0;
int startY = 0;
int Offset = 0;

graphics.DrawString("Welcome to MSST", new Font("Courier New", 14), new SolidBrush(Color.Black), startX, startY + Offset);
Offset = Offset + 20;

graphics.DrawString("Recept No :" + receptno + 1, new Font("Courier New", 14), new SolidBrush(Color.Black), startX, startY + Offset);
Offset = Offset + 20;

graphics.DrawString("Date :" + DateTime.Today, new Font("Courier New", 12), new SolidBrush(Color.Black), startX, startY + Offset);
Offset = Offset + 20;

graphics.DrawString("------------------------------------------", new Font("Courier New", 10), new SolidBrush(Color.Black), startX, startY + Offset);
Offset = Offset + 20;

Can anyone help me out with text align?

UPDATE: Here is the desired output:

             Welcome to MSST             
Receipt No : 3
Date : 5/24/2014 10:06:22

解决方案

Here is the full code of your example, using three StringFormats and an added line to show right aligned text.. I have also added a leading number and converted everything to floats.. I was using a Panel to draw on and set the layout Rectangle to the Panel's dimensions. You should use your printing target, of course..

int receptno = 42;
Graphics graphics = e.Graphics;

Font font10 = new Font("Courier New", 10);
Font font12 = new Font("Courier New", 12);
Font font14 = new Font("Courier New", 14);

float leading = 4;
float lineheight10 = font10.GetHeight() + leading;
float lineheight12 = font12.GetHeight() + leading;
float lineheight14 = font14.GetHeight() + leading;

float startX = 0;
float startY = leading;
float Offset = 0;

StringFormat formatLeft = new StringFormat(StringFormatFlags.NoClip);
StringFormat formatCenter = new StringFormat(formatLeft);
StringFormat formatRight = new StringFormat(formatLeft);

formatCenter.Alignment = StringAlignment.Center;
formatRight.Alignment = StringAlignment.Far;
formatLeft.Alignment = StringAlignment.Near;

SizeF layoutSize = new SizeF(yourPrintAreaWidth - Offset * 2, lineheight14);
RectangleF layout = new RectangleF(new PointF(startX, startY + Offset), layoutSize);

Brush  brush = Brushes.Black;

graphics.DrawString("Welcome to MSST", font14, brush, layout, formatCenter);
Offset = Offset + lineheight14;
layout = new RectangleF(new PointF(startX, startY + Offset), layoutSize);
graphics.DrawString("Recept No :" + receptno + 1, font14, brush, layout, formatLeft);
Offset = Offset + lineheight14;
layout = new RectangleF(new PointF(startX, startY + Offset), layoutSize);
graphics.DrawString("Date :" + DateTime.Today, font12, brush, layout, formatLeft);
Offset = Offset + lineheight12;
layout = new RectangleF(new PointF(startX, startY + Offset), layoutSize);
graphics.DrawString("".PadRight(46,'_'), font10, brush, layout, formatLeft);
Offset = Offset + lineheight10;
layout = new RectangleF(new PointF(startX, startY + Offset), layoutSize);

graphics.DrawString("copyright SO", font10, brush, layout, formatRight);
Offset = Offset + lineheight10;

font10.Dispose();   font12.Dispose();  font14.Dispose();
