This code only print text in richtextbox but
how can print text and image in the richtextbox?

I think, you need rewrite function DocumentToPrint_PrintPage for render rtf to e.Graphics with text and images. Now, the function render only text from RichTextBox.Text.
You need read from RichTextBox.rtf, and parse it and draw it like e.Graphics.DrawString (docs) for texts and e.Graphics.DrawImage (docs) for images

Create a pdf from pdf with images and watermark

From a pdf, I want to make a new pdf that I 'll add a watermark and then make each page an image page.
Is this possible with itext?
I don't know how to convert it to images, but for the watermark, as said by Usama Kiyani in comments, you should consider using itextsharp which can be installed through nugget packages manager. I already used it to add a water mark to an existing pdf file.
Here's the code I used, it add a diagonal red watermark (which text is argument watermarkText) in the center of each page of an existing pdf file (sourceFile), then save this modified version at the given location (outputFile) :
public static void AddWatermarkTextC(string sourceFile, string outputFile, string watermarkText)
{
BaseFont tWatermarkFont = null;
float tWatermarkFontSize = 48F;
iTextSharp.text.BaseColor tWatermarkFontColor = null;
float tWatermarkFontOpacity = 0.3F;
float tWatermarkRotation = 45.0F;
tWatermarkFont = iTextSharp.text.pdf.BaseFont.CreateFont(iTextSharp.text.pdf.BaseFont.HELVETICA, iTextSharp.text.pdf.BaseFont.CP1252, iTextSharp.text.pdf.BaseFont.NOT_EMBEDDED);
tWatermarkFontColor = iTextSharp.text.BaseColor.RED;
AddWatermarkTextC(sourceFile, outputFile, watermarkText, tWatermarkFont, tWatermarkFontSize, tWatermarkFontColor, tWatermarkFontOpacity, tWatermarkRotation);
}
public static void AddWatermarkTextC(string sourceFile, string outputFile, string watermarkText, iTextSharp.text.pdf.BaseFont watermarkFont, float watermarkFontSize, iTextSharp.text.BaseColor watermarkFontColor, float watermarkFontOpacity, float watermarkRotation)
{
iTextSharp.text.pdf.PdfReader reader = null;
iTextSharp.text.pdf.PdfStamper stamper = null;
iTextSharp.text.pdf.PdfGState gstate = null;
iTextSharp.text.pdf.PdfContentByte underContent = null;
iTextSharp.text.Rectangle rect = null;
float currentY = 0.0F;
float offset = 0.0F;
int pageCount = 0;
try
{
reader = new iTextSharp.text.pdf.PdfReader(sourceFile);
rect = reader.GetPageSizeWithRotation(1);
FileStream stream = new System.IO.FileStream(outputFile, System.IO.FileMode.Create);
stamper = new iTextSharp.text.pdf.PdfStamper(reader, stream);
if (watermarkFont == null)
{
watermarkFont = iTextSharp.text.pdf.BaseFont.CreateFont(iTextSharp.text.pdf.BaseFont.HELVETICA, iTextSharp.text.pdf.BaseFont.CP1252, iTextSharp.text.pdf.BaseFont.NOT_EMBEDDED);
}
if (watermarkFontColor == null)
{
watermarkFontColor = iTextSharp.text.BaseColor.RED;
}
gstate = new iTextSharp.text.pdf.PdfGState();
gstate.FillOpacity = watermarkFontOpacity;
gstate.StrokeOpacity = watermarkFontOpacity;
pageCount = reader.NumberOfPages;
for (int i = 1; i <= pageCount; i++)
{
underContent = stamper.GetOverContent(i);
underContent.SaveState();
underContent.SetGState(gstate);
underContent.SetColorFill(watermarkFontColor);
underContent.BeginText();
underContent.SetFontAndSize(watermarkFont, watermarkFontSize);
underContent.SetTextMatrix(30, 30);
currentY = (rect.Height / 2);
underContent.ShowTextAligned(iTextSharp.text.Element.ALIGN_CENTER, watermarkText, rect.Width / 2, currentY - offset, watermarkRotation);
underContent.EndText();
underContent.RestoreState();
}
stamper.Close();
reader.Close();
stream.Close();
}
catch (Exception ex)
{
throw ex;
}
}
I guess it's not really hard to change it to fit your need, but if there's is anything you need me to explain just ask for it.

Pass PaintEventArgs into method

I have the following method in C#:
private string adjustColumnValueLength(String value, int maxLength, PaintEventArgs e)
{
// Set up our string font
System.Drawing.Font printFontText = new System.Drawing.Font("Arial", 12, System.Drawing.FontStyle.Regular);
SizeF stringSize = new SizeF();
string newValue = value;
// Loop until the string fits the size we need
for (int x = value.Length; x >= 0; x--)
{
// Measure the string
newValue = value.Substring(0, x);
stringSize = e.Graphics.MeasureString(newValue, printFontText);
Size roundedSize = Size.Round(stringSize);
if (Int32.Parse(roundedSize.ToString()) <= maxLength)
{
return newValue;
}
}
return newValue;
}
I am calling this from within another method to get the length of a string to match the width in pixels I have to display it, however I have NO idea how I am supposed to pass in the PaintEventArgs. I've tried using System.Windows.Forms.PaintEventArgs but that does not work.
How can this be accomplished?

Complete code provided above, I'm trying to call the adjustColumnValueLength from within the ticketData method so that I can substring the value that is being printed to only the width I have available for that column.
You should only call that method from a Paint event handler. I guess you have something in your code like:
private void Control_Paint(object sender, PainEventArgs e) { ... }
You should call your method from there (and nowhere else!):
private void Control_Paint(object sender, PainEventArgs e)
{
adjustColumnValueLength("value", 10, e);
}
If you don't have that, create a event handler:
this.Control.Paint += Control_Paint;
Also read: Custom Control Painting and Rendering.

Print on specific coordinates

I have a card that has10cm height and 15cm width. I am trying to print a string on the following coordinates: 1,5cm from top to bottom and 3,5cm from the left to right. Until now i tried to use the bellow code that i found on msdn but with no luck. The code that i am using is :
System.IO.StreamReader fileToPrint;
System.Drawing.Font printFont;
private void printButton_Click(object sender, EventArgs e)
{
string printPath = System.Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
fileToPrint = new System.IO.StreamReader(printPath + #"\myFile.txt");
printFont = new System.Drawing.Font("Arial", 10);
printDocument1.Print();
fileToPrint.Close();
}
private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
{
float yPos = 0f;
int count = 0;
float leftMargin = e.MarginBounds.Left;
float topMargin = e.MarginBounds.Top;
string line = null;
float linesPerPage = e.MarginBounds.Height/printFont.GetHeight(e.Graphics);
while (count < linesPerPage)
{
line = fileToPrint.ReadLine();
if (line == null)
{
break;
}
yPos = topMargin + count * printFont.GetHeight(e.Graphics);
e.Graphics.DrawString(line, printFont, Brushes.Black, leftMargin, yPos, new StringFormat());
count++;
}
if (line != null)
{
e.HasMorePages = true;
}
}

How to Print images on paper using PrintDocument

My problem is that is that my code prints the images overlapping each other. I do not know how to change the x and y positions. The printer should print 3 images per row and then move to the next row.

if (alphabet39.IndexOf(barcodestring[i]) == -1 || barcodestring[i] == '*')
{
e.Graphics.DrawString("INVALID BAR CODE TEXT", Font, Brushes.Red, 10, 10);
return;
}
}
String encodedString = "";
for (int i = 0; i < strLength; i++)
{

Desired output :
I am getting :
As you can see the last digit is overlapping. I want to draw it next to the previous one
I have observed the code and found the issue.. in panel1_print u are not incrementing the values properly..
I have made the required changes now u will get the 4 bar in a line and 5th one in another line - check the attached image.
just replace ur panel1_Paint with this new code thats it you can find the changes..
I have marked them as
//start changes by Deepak
..
..
..
//end changes by Deepak

You Should do it with the help of a DataGridView (That Contains Images in a Column).
The Images Will Then Print in each new row or column (by modifying as your desire)

Your position variables are being declared inside the loop, meaning that they are reset for each pass through the loop. Keep position variables for X and Y outside of the loop over serial and adjust it for the total width (and height, if you start a new row of barcodes) of each barcode.

How to print one large image in many pages?

I want to print one tall (long) image in many pages. So in every page, I take a suitable part from the image and I draw it in the page.
the problem is that I have got the image shrunk (its shape is compressed) in the page,so I added an scale that its value is 1500 .
I think that I can solve the problem if I knew the height of the page (e.Graphics) in pixels.
to convert Inches to Pixel, Do I have to multiply by (e.Graphics.DpiX = 600) or multiply by 96 .
void printdocument_PrintPage(object sender, PrintPageEventArgs e)
{
if (pageImage == null)
return;
e.Graphics.PageUnit = GraphicsUnit.Pixel;
e.Graphics.InterpolationMode = InterpolationMode.HighQualityBicubic;
e.Graphics.PixelOffsetMode = PixelOffsetMode.HighQuality;
float a = (e.MarginBounds.Width / 100) * e.Graphics.DpiX;
float b = ((e.MarginBounds.Height / 100) * e.Graphics.DpiY);
int scale = 1500;
scale = 0; //try to comment this
RectangleF srcRect = new RectangleF(0, startY, pageImage.Width, b - scale);
RectangleF destRect = new RectangleF(0, 0, a, b);
e.Graphics.DrawImage(pageImage, destRect, srcRect, GraphicsUnit.Pixel);
startY = Convert.ToInt32(startY + b - scale);
e.HasMorePages = (startY < pageImage.Height);
}
could you please make it works correctly.
you can download the source code from (here).
thanks in advanced.
I tried to complete your task.
Here you go. Hope it helps.
This method prints the image on several pages (or one if image is small).
private void printImage_Btn_Click(object sender, EventArgs e)
{
list = new List<Image>();
Graphics g = Graphics.FromImage(image_PctrBx.Image);
Brush redBrush = new SolidBrush(Color.Red);
Pen pen = new Pen(redBrush, 3);
decimal xdivider = image_PctrBx.Image.Width / 595m;
int xdiv = Convert.ToInt32(Math.Ceiling(xdivider));
decimal ydivider = image_PctrBx.Image.Height / 841m;
int ydiv = Convert.ToInt32(Math.Ceiling(ydivider));
/*int xdiv = image_PctrBx.Image.Width / 595; //This is the xsize in pt (A4)
int ydiv = image_PctrBx.Image.Height / 841; //This is the ysize in pt (A4)
// # 72 dots-per-inch - taken from Adobe Illustrator
if (xdiv >= 1 && ydiv >= 1)
{*/
for (int i = 0; i < xdiv; i++)
{
for (int y = 0; y < ydiv; y++)
{
Rectangle r;
try
{
r = new Rectangle(i * Convert.ToInt32(image_PctrBx.Image.Width / xdiv),
y * Convert.ToInt32(image_PctrBx.Image.Height / ydiv),
image_PctrBx.Image.Width / xdiv,
image_PctrBx.Image.Height / ydiv);
}
catch (Exception)
{

y * Convert.ToInt32(image_PctrBx.Image.Height),
image_PctrBx.Image.Width / xdiv,
image_PctrBx.Image.Height);
}
g.DrawRectangle(pen, r);
list.Add(cropImage(image_PctrBx.Image, r));
}
}
g.Dispose();
image_PctrBx.Invalidate();
image_PctrBx.Image = list[0];
PrintDocument printDocument = new PrintDocument();
printDocument.PrintPage += PrintDocument_PrintPage;
PrintPreviewDialog previewDialog = new PrintPreviewDialog();
previewDialog.Document = printDocument;
pageIndex = 0;
previewDialog.ShowDialog();
// don't forget to detach the event handler when you are done
printDocument.PrintPage -= PrintDocument_PrintPage;
}
This method prints every picture in the List in the needed dimensions (A4 size):
private void PrintDocument_PrintPage(object sender, PrintPageEventArgs e)
{
// Draw the image for the current page index
e.Graphics.DrawImageUnscaled(list[pageIndex],
e.PageBounds.X,
e.PageBounds.Y);
// increment page index
pageIndex++;
// indicate whether there are more pages or not
e.HasMorePages = (pageIndex < list.Count);
}
This method crops the image and returns every part of the image:
private static Image cropImage(Image img, Rectangle cropArea)
{
Bitmap bmpImage = new Bitmap(img);
Bitmap bmpCrop = bmpImage.Clone(cropArea, System.Drawing.Imaging.PixelFormat.DontCare);
return (Image)(bmpCrop);
}
The Image gets loaded from the PictureBox, so make sure the image is loaded. (No exception handling yet).
internal string tempPath { get; set; }
private int pageIndex = 0;
internal List<Image> list { get; set; }
These variables are defined as global variables.
