e.graphics.DrawString text cuts off from R.H.S of the page

[Ahmedhussain]

Hi.

I am having a problem in printing text to printer through printPage event using e.grphics.drawS tring method. On printdocument.p rintPage event When it draws the string, text from the right hand side of the page gets out.. And printer finishes printing...

void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
        {
            Font myFont = new Font("m_svoboda", 14, FontStyle.Underline, GraphicsUnit.Point);
            
            siteHTML = webBrowser1.Document.Body.InnerHtml + webBrowser1.Document.Body.OuterHtml;

            float lineHeight = myFont.GetHeight(e.Graphics) + 4;
            float yLineTop = e.MarginBounds.Top;
                        
                if (yLineTop + lineHeight > e.MarginBounds.Bottom)
                {
                    e.HasMorePages = true;
                    return;
                }
                //e.Graphics.DrawString(siteHTML, myFont, Brushes.Black,
                  //  new PointF(e.MarginBounds.Left, yLineTop));
                e.Graphics.DrawString(siteHTML, myFont, Brushes.Black, e.PageSettings.PrintableArea.X, e.PageSettings.PrintableArea.Y);
                yLineTop += lineHeight;
            
            e.HasMorePages = false;
        }

How will I deal with this problem?

What you need to take into consider is that DrawString does not automatically wrap your text, nor is there a function to do this automatically, however the Graphics class does offer the method MeasureString, though seeing as I love working with the graphics class admittedly, here is a method that will help you:

private void DrawWrappedString(Graphics g, Font font, string str, int maxWidth, Brush brush, PointF position, int rightMargin = 30, int lineSpacing = 0)
        {
            SizeF s = g.MeasureString(str, font);
            string lineBuffer = "";
            float lineHeight = s.Height;
            float y = position.Y;
            PointF linePosition = new PointF(0, 0);
            foreach (char c in str)
            {
                s = g.MeasureString(lineBuffer, font);
                if (s.Width >= (maxWidth - position.X - rightMargin) && c == ' ')
                { 
                    linePosition = new PointF(position.X, y);
                    g.DrawString(lineBuffer.Trim(), font, brush, linePosition);
                    y += lineHeight + lineSpacing;
                    lineBuffer = "";
                }
                lineBuffer += c.ToString();
            }
            linePosition = new PointF(position.X, y);
            g.DrawString(lineBuffer.Trim(), font, brush, linePosition);
        }

Hi,

I like the work, but need to know width parameter will take width of what?

Thank you,

[Aimee Bailey]

luckily the method you are in actually has this information :) just use:

int width = e.PageBounds.Width;

Aimee.

[Ahmedhussain]

hey,
Thanks for the code, but it still cuts the text from the right hand side. is there any way to stop this?

[Ahmedhussain]

I used this, it was working fine except for the e.pagebounds.wi dth. So I divided the width by 2, And now it prints on almost half of my page.

Ahmed

I was under the impression that if you used the overload of DrawString that took a rectangle, it would wrap the text to be contained inside the rectangle.
It mentions this in the StringFormatFla gs enum where you can tell it NoWrap or DirectionRightT oLeft and other options

[Ahmedhussain]

Hi,
Platter, I would appreciate if you give me some code... Cause I am not getting a proper understanding of e.graphics, to print on a piece of a paper. :'(

[Plater]

Take a look at the DrawString function:
g.DrawString(St ringToDraw, FontToUse, BrushToUse, RectangleFToUse , StringFormatToU se);

If you supply a bounding RectangleF, instead of just a starting point, the text will be wrapped.


Here's an example showing 2 different types. The first example word wraps, but could leave a partial line (the tops of the glyphs used in xenophobia)
while the 2nd type forces only whole lines to be drawn, it character wraps. I didn't play around enough to see if you could make both happen.

private static void DemoBitmap()
{
  Bitmap bm = new Bitmap(100, 100, PixelFormat.Format32bppArgb);
  Graphics g= Graphics.FromImage(bm);

  string StringToDraw = "Don had a lot of rancid cats. The cats liked his xenophobia very much.";
  Font FontToUse = new Font(FontFamily.GenericSansSerif, 10);
  Brush BrushToUse = new SolidBrush(Color.Black);
  int margin = 10;//10pixels
  RectangleF RectangleFToUse = new RectangleF(margin, margin, bm.Width - (2 * margin), bm.Height - (2 * margin));
  StringFormat StringFormatToUse = new StringFormat();//can add StringFormatFlags here 

  g.Clear(Color.White);
  g.DrawRectangle(new Pen(BrushToUse), 0, 0, bm.Width-1, bm.Height-1);
  g.DrawString(StringToDraw, FontToUse, BrushToUse, RectangleFToUse, StringFormatToUse);
  bm.Save(@"c:\boundedbmp1.bmp", ImageFormat.Bmp );//will have a partial line shown

  g.Clear(Color.White);
  g.DrawRectangle(new Pen(BrushToUse), 0, 0, bm.Width-1, bm.Height-1);
  StringFormatToUse.FormatFlags = StringFormatToUse.FormatFlags | StringFormatFlags.LineLimit;
  g.DrawString(StringToDraw, FontToUse, BrushToUse, RectangleFToUse, StringFormatToUse);
  bm.Save(@"c:\boundedbmp2.bmp", ImageFormat.Bmp);//will not have a partial line shown, wraps on character
}

Platter, It create bitmaps great.. But still tell me how to print.

private static void DemoBitmap(String str, Graphics g1)
        {
              Bitmap bm = new Bitmap(750, 1000, PixelFormat.Format32bppArgb);
              Graphics g = Graphics.FromImage(bm);
              g1 = Graphics.FromImage(bm);
              string StringToDraw = str;//"Donhad a lot of rancid cats. The cats liked his xenophobia very much.";
              Font FontToUse = new Font(FontFamily.GenericSansSerif, 10);
              Brush BrushToUse = new SolidBrush(Color.DarkBlue);
              int margin = 10;//10pixels
              RectangleF RectangleFToUse = new RectangleF(margin, margin, bm.Width - (2 * margin), bm.Height - (2 * margin));
              StringFormat StringFormatToUse = new StringFormat();//can add StringFormatFlags here 
              
              g1.Clear(Color.White);
              g1.DrawRectangle(new Pen(BrushToUse), 0, 0, bm.Width - 1, bm.Height - 1);
              g.DrawString(StringToDraw, FontToUse, BrushToUse, RectangleFToUse, StringFormatToUse);
              g1.DrawString(StringToDraw, FontToUse, BrushToUse, RectangleFToUse, StringFormatToUse);
              //bm.Save(@"d:\boundedbmp1.bmp", ImageFormat.Bmp);//will have a partialline shown

              g1.Clear(Color.White);
              g1.DrawRectangle(new Pen(BrushToUse), 0, 0, bm.Width - 1, bm.Height - 1);
              StringFormatToUse.FormatFlags = StringFormatToUse.FormatFlags | StringFormatFlags.LineLimit;
              g1.DrawString(StringToDraw, FontToUse, BrushToUse, RectangleFToUse, StringFormatToUse);
             // bm.Save(@"d:\boundedbmp2.bmp", ImageFormat.Bmp);//will not have a partial line shown, wraps on character
        }

but it doesnt print any thing .. I get only blank paper on my print event :(

[Ahmedhussain]

What I did to print on the page properly is this.

void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
        {
            siteHTML = webBrowser1.Document.Body.OuterHtml;
            float linesPerPage = 0;
            float leftMargin = e.MarginBounds.Left;
            float topMargin = e.MarginBounds.Top;
            String line = null;

            byte[] byteArray = Encoding.ASCII.GetBytes(siteHTML);
            MemoryStream stream = new MemoryStream(byteArray);
            StreamReader reader = new StreamReader(stream);

            e.PageSettings.Color = true;
            rptFont = new Font("Arial", 10);
            linesPerPage = e.MarginBounds.Height / rptFont.GetHeight(e.Graphics);
            
            e.PageSettings.PaperSize = new PaperSize("A4", 8, 11);
            float lineHeight = rptFont.GetHeight(e.Graphics);
            
            int count = 0;
            while (((line = reader.ReadLine()) != null)&& count<linesPerPage)
            {
                Rectangle rect = new Rectangle(20, 20 + Convert.ToInt32(lineHeight * count), 800, Convert.ToInt32(lineHeight));
                e.Graphics.DrawString(line, rptFont, Brushes.BlueViolet, rect, new StringFormat());
                count++;
            }
        }

But now I have to look for a next page to print it properly. If I do something like,

if (count > linesPerPage)
                    e.HasMorePages = true;
                else
                    e.HasMorePages = false;

The code will go boom. :@
How would it be possible to print another page???

[Ahmedhussain]

Well not the code, but the count for pages go unlumited :s

The bitmap was just an example. Printing works with the same Graphics object. It's just a big empty bitmap that is printed
