C# how to print out an array of PictureBox in multiple pages

using C#, I wrote the below code to print out images in an array (size = totalToPrint) of Picturebox pictureBoxArr[] each in size of 100x100 pixel. I want to print them vertically with the 20-pixel distance between them heightDistanceBetweenImages the problem is that it only prints on 1 page (say letter size) no matter how many images ( then it only prints 8 images and dismisses the rest). How can I solve this problem, and print it on multiple pages?
int totalToPrint;
int xFirstAncorPoint = 100;
int yFirstAncorPoint = 100;
int ImagSize = 100; // Squre of 100x100 pixel
int heightDistanceBetweenImages = 20;
PrintDialog pd = new PrintDialog();
PrintDocument pDoc = new PrintDocument();
pDoc.PrintPage += PrintPicture;
pd.Document = pDoc;
if (pd.ShowDialog() == DialogResult.OK)
{
pDoc.Print();
}
}
public void PrintPicture(Object sender, PrintPageEventArgs e)
{
Bitmap bmp1 = new Bitmap(ImagSize , totalToPrint * (ImagSize + heightDistanceBetweenImages));
for (int i = 0; i < totalToPrint; i++)
{
pictureBoxArr[i].DrawToBitmap(bmp1, new Rectangle(0, i * (heightDistanceBetweenImages + ImagSize), pictureBoxArr[0].Width, pictureBoxArr[0].Height));
}
e.Graphics.DrawImage(bmp1, xFirstAncorPoint, yFirstAncorPoint);
bmp1.Dispose();
}

You are about half way there. PrintDocument would be your future reference.
The PrintPage gives you more than just a drawing space; it also has your page bounds, page margins, etc. It also has HasMorePages property that you set if you need to print more pages. This property defaults to false, so you were only printing 1 page. Also if anything is outside the bounds of the page, it would not print that. With a little change here and there, you would end up with something like this.
// using queue to manage images to print
Queue<Image> printImages = new Queue<Image>();
int totalToPrint;
int xFirstAncorPoint = 100;
int yFirstAncorPoint = 100;
int ImagSize = 100; // Squre of 100x100 pixel
int heightDistanceBetweenImages = 20;
private void btnPrintTest_Click(object sender, EventArgs e) {
PrintDialog pd = new PrintDialog();
PrintDocument pDoc = new PrintDocument();
pDoc.PrintPage += PrintPicture;
pd.Document = pDoc;
if (pd.ShowDialog() == DialogResult.OK) {
// add image references to printImages queue.
for (int i = 0; i < pictureBoxArr.Length; i++) {
printImages.Enqueue(pictureBoxArr[i].Image);
}
pDoc.Print();
}
}
private void PrintPicture(object sender, PrintPageEventArgs e) {
int boundsHeight = e.MarginBounds.Height; // Get height of bounds that we are expected to print in.
int currentHeight = yFirstAncorPoint;
while (currentHeight <= boundsHeight && printImages.Count > 0) {
var nextImg = printImages.Peek();
int nextElementHeight = nextImg.Height + heightDistanceBetweenImages;
if (nextElementHeight + currentHeight <= boundsHeight) {
e.Graphics.DrawImage(nextImg, new PointF(xFirstAncorPoint, currentHeight + heightDistanceBetweenImages));
printImages.Dequeue();
}
currentHeight += nextElementHeight;
}
// how we specify if we may have more pages to print
e.HasMorePages = printImages.Count > 0;
}
Hopefully this gets you on the right path and with some minor tweaks for your code, you will have what you need.

Zooming / Resizing Images get blurry

I’m using WinForms. My application works like a simple image viewer. It opens Image files goes to the next page, zooms in and zooms out. The problem with my application is that when I re-size or zoom in the image, the image starts getting blurry. How do I prevent my images from getting blurry when I’m zooming out or zooming in?
When i view and re-size the same image on Windows Photo Viewer the images is clear. When i open the image in my application the image is clear but as soon as i start re sizing it for example when i start using zoom it starts becoming blurry.
I tried implementing this code in my zoom out method but i didn't couldn't figure out how to do it.
Size newSize = new Size((int)(originalBitmap.Width * zoomFactor),
(int)(originalBitmap.Height * zoomFactor));
Bitmap bmp = new Bitmap(originalBitmap, newSize);
The image dimensions i look at:
Dimensions: 2540 x 3289
Dimensions: 2533 x 3284
Dimensions: 2538 x 3282
Dimensions: 2479 x 3508

Image img = Image.FromFile(openFileDialog1.FileName);
pictureBox1.Image = img;
pictureBox1.Width = img.Width;
pictureBox1.Height = img.Height;
this.pictureBox1.Image.RotateFlip(RotateFlipType.Rotate90FlipNone); // Rotates image 90 degrees
}
}
public void Open_Image_Control()
{
Image myBmp;
if (_myImg == null)
{
_fileName = Path.Combine(Path.GetTempPath(), Guid.NewGuid().ToString("N"));
File.Copy(#lblFile.Text, _fileName);
_stream = new FileStream(_fileName, FileMode.Open, FileAccess.Read);
_myImg = Image.FromStream(_stream);
}
int intPages = _myImg.GetFrameCount(System.Drawing.Imaging.FrameDimension.Page); // getting the number of pages of this tiff
intPages--; // the first page is 0 so we must correct the number of pages to -1
lblNumPages.Text = Convert.ToString(intPages); // showing the number of pages
lblCurrPage.Text = Convert.ToString(intCurrPage); // showing the number of page on which we're on
_myImg.SelectActiveFrame(System.Drawing.Imaging.FrameDimension.Page, intCurrPage); // going to the selected page

How to print using multiple screenshots captured with copyfromscreen

I'm pretty new to C# but I finally have my first program up and running and I need to make it print. Its a window form with information and calculations on different tab controls, somewhat like Excel. The page that is currently being looked at prints fine with the copyfromscreen method, but I cannot get additional pages to print correctly. I have about 20 tabs I would like to be able to print at one time. I found a way to print the contents of controls into a textfile, but I would much prefer to be able to print what the form looks like. Thanks.
Bitmap memoryImage;
Bitmap memoryImage2;
private void CaptureScreen()
{
Graphics myGraphics = this.CreateGraphics();
Size s = tabControlMain.Size;
s.Width = s.Width + 20;
memoryImage = new Bitmap(s.Width, s.Height, myGraphics);
Graphics memoryGraphics = Graphics.FromImage(memoryImage);
memoryGraphics.CopyFromScreen(this.Location.X+15, this.Location.Y+80, 0, 0, s);
tabControlMain.SelectedIndex = 1;
memoryImage2 = new Bitmap(s.Width, s.Height, myGraphics);
Graphics memoryGraphics2 = Graphics.FromImage(memoryImage2);
memoryGraphics2.CopyFromScreen(this.Location.X + 15, this.Location.Y + 80, 0, 0, s);
}
private void printDocumentReal_PrintPage(System.Object sender, System.Drawing.Printing.PrintPageEventArgs e)
{
e.Graphics.DrawImage(memoryImage, 0, 0);
e.Graphics.DrawImage(memoryImage2, 0, 550);
}
private void printToolStripButton_Click(object sender, EventArgs e)
{
CaptureScreen();
printDocumentReal.Print();
}

First, you should use PrintDocument and PrintPreviewDialog objects for print related tasks and an event handler for printing.
Second, you need to preform some optimization for your code, here's the solution:
private void printToolStripButton_Click(object sender, EventArgs e)
{
PrintDocument document = new PrintDocument();
document.PrintPage += new PrintPageEventHandler(document_PrintPage);
PrintPreviewDialog preview = new PrintPreviewDialog() { Document = document };
// you will be able to preview all pages before print it ;)
try
{
preview.ShowDialog();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message + "\nYou need to install a printer to preform print-related tasks!", "Print Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
Boolean firstPage = true;
private void document_PrintPage(object sender, PrintPageEventArgs e)
{
if (firstPage)
{
tabControlMain.SelectTab(0);
firstPage = false;
}
Graphics g = e.Graphics;
TabPage tab = tabControlMain.SelectedTab;
using (Bitmap img = new Bitmap(tab.Width, tab.Height))
{
tab.DrawToBitmap(img, tab.ClientRectangle);
g.DrawImage(img, new Point(e.MarginBounds.X, e.MarginBounds.Y)); // MarginBounds means the margins of the page
}
if (tabControlMain.SelectedIndex + 1 < tabControlMain.TabCount)
{
tabControlMain.SelectedIndex++;
e.HasMorePages = true;//If you set e.HasMorePages to true, the Document object will call this event handler again to print the next page.
}
else
{
e.HasMorePages = false;
firstPage = true;
}
}
I hope it's working fine with you And here's an additional one if you need to save all tabs as set of images on your hard disk:
public void RenderAllTabs()
{
foreach (TabPage tab in tabControlMain.TabPages)
{
tabControlMain.SelectTab(tab);
using (Bitmap img = new Bitmap(tab.Width, tab.Height))
{
tab.DrawToBitmap(img, tab.ClientRectangle);
img.Save(string.Format(#"C:\Tabs\{0}.png", tab.Text));
}
}
}

Try using DrawToBitmap method of TabPage instead:
private void CaptureScreen()
{
memoryImage = new Bitmap(tabControlMain.SelectedTab.Width, tabControlMain.SelectedTab.Height);
tabControlMain.SelectedTab.DrawToBitmap(memoryImage, tabControlMain.SelectedTab.ClientRectangle);
tabControlMain.SelectedIndex = 1;
memoryImage2 = new Bitmap(tabControlMain.SelectedTab.Width, tabControlMain.SelectedTab.Height);
tabControlMain.SelectedTab.DrawToBitmap(memoryImage2, tabControlMain.SelectedTab.ClientRectangle);
}
To get all the images of your TabPages, you can make a loop like this:
List<Bitmap> images = new List<Bitmap>();
private void CaptureScreen(){
foreach(TabPage page in tabControlMain.TabPages){
Bitmap bm = new Bitmap(page.Width, page.Height);
tabControlMain.SelectedTab = page;
page.DrawToBitmap(bm, page.ClientRectangle);
images.Add(bm);
}
}
//Then you can access the images of your TabPages in the list images
//the index of TabPage is corresponding to its image index in the list images

Printing image with PrintDocument. how to adjust the image to fit paper size

In C#, I am trying to print an image using PrintDocument class with the below code. The image is of size 1200 px width and 1800 px height. I am trying to print this image in a 4*6 paper using a small zeebra printer. But the program is printing only 4*6 are of the big image. that means it is not adjusting the image to the paper size !
PrintDocument pd = new PrintDocument();
pd.PrintPage += (sender, args) =>
{
Image i = Image.FromFile("C://tesimage.PNG");
Point p = new Point(100, 100);
args.Graphics.DrawImage(i, 10, 10, i.Width, i.Height);
};
pd.Print();
When i print the same image using Window Print (right click and select print, it is scaling automatically to paper size and printing correctly. that means everything came in 4*6 paper.) How do i do the same in my C# program ?

The parameters that you are passing into the DrawImage method should be the size you want the image on the paper rather than the size of the image itself, the DrawImage command will then take care of the scaling for you. Probably the easiest way is to use the following override of the DrawImage command.
args.Graphics.DrawImage(i, args.MarginBounds);
Note: This will skew the image if the proportions of the image are not the same as the rectangle. Some simple math on the size of the image and paper size will allow you to create a new rectangle that fits in the bounds of the paper without skewing the image.

Not to trample on BBoy's already decent answer, but I've done the code that maintains aspect ratio. I took his suggestion, so he should get partial credit here!
PrintDocument pd = new PrintDocument();
pd.DefaultPageSettings.PrinterSettings.PrinterName = "Printer Name";
pd.DefaultPageSettings.Landscape = true; //or false!
pd.PrintPage += (sender, args) =>
{
Image i = Image.FromFile(#"C:\...\...\image.jpg");
Rectangle m = args.MarginBounds;
if ((double)i.Width / (double)i.Height > (double)m.Width / (double)m.Height) // image is wider
{
m.Height = (int)((double)i.Height / (double)i.Width * (double)m.Width);
}
else
{
m.Width = (int)((double)i.Width / (double)i.Height * (double)m.Height);
}
args.Graphics.DrawImage(i, m);
};
pd.Print();

The solution provided by BBoy works fine. But in my case I had to use
e.Graphics.DrawImage(memoryImage, e.PageBounds);
This will print only the form. When I use MarginBounds it prints the entire screen even if the form is smaller than the monitor screen. PageBounds solved that issue. Thanks to BBoy!

You can use my code here
//Print Button Event Handeler
private void btnPrint_Click(object sender, EventArgs e)
{
PrintDocument pd = new PrintDocument();
pd.PrintPage += PrintPage;
//here to select the printer attached to user PC
PrintDialog printDialog1 = new PrintDialog();
printDialog1.Document = pd;
DialogResult result = printDialog1.ShowDialog();
if (result == DialogResult.OK)
{
pd.Print();//this will trigger the Print Event handeler PrintPage
}
}
//The Print Event handeler
private void PrintPage(object o, PrintPageEventArgs e)
{
try
{
if (File.Exists(this.ImagePath))
{
//Load the image from the file
System.Drawing.Image img = System.Drawing.Image.FromFile(#"C:\myimage.jpg");
//Adjust the size of the image to the page to print the full image without loosing any part of it
Rectangle m = e.MarginBounds;
if ((double)img.Width / (double)img.Height > (double)m.Width / (double)m.Height) // image is wider
{
m.Height = (int)((double)img.Height / (double)img.Width * (double)m.Width);
}
else
{
m.Width = (int)((double)img.Width / (double)img.Height * (double)m.Height);
}
e.Graphics.DrawImage(img, m);
}
}
catch (Exception)
{
}
}

Agree with TonyM and BBoy - this is the correct answer for original 4*6 printing of label. (args.PageBounds). This worked for me for printing Endicia API service shipping Labels.
private void SubmitResponseToPrinter(ILabelRequestResponse response)
{
PrintDocument pd = new PrintDocument();
pd.PrintPage += (sender, args) =>
{
Image i = Image.FromFile(response.Labels[0].FullPathFileName.Trim());
args.Graphics.DrawImage(i, args.PageBounds);
};
pd.Print();
}

all these answers has the problem, that's always stretching the image to pagesize and cuts off some content at trying this.
Found a little bit easier way.
My own solution only stretch(is this the right word?) if the image is to large, can use multiply copies and pageorientations.
PrintDialog dlg = new PrintDialog();
if (dlg.ShowDialog() == true)
{
BitmapImage bmi = new BitmapImage(new Uri(strPath));
Image img = new Image();
img.Source = bmi;
if (bmi.PixelWidth < dlg.PrintableAreaWidth ||
bmi.PixelHeight < dlg.PrintableAreaHeight)
{
img.Stretch = Stretch.None;
img.Width = bmi.PixelWidth;
img.Height = bmi.PixelHeight;
}
if (dlg.PrintTicket.PageBorderless == PageBorderless.Borderless)
{
img.Margin = new Thickness(0);
}
else
{
img.Margin = new Thickness(48);
}
img.VerticalAlignment = VerticalAlignment.Top;
img.HorizontalAlignment = HorizontalAlignment.Left;
for (int i = 0; i < dlg.PrintTicket.CopyCount; i++)
{
dlg.PrintVisual(img, "Print a Image");
}
}

How can I print the large dataGridView/Form on multiple pages?

Just using Win Forms in C#. Created Data Grid View and added print button. Here is my code for print button.
private void toolStripButton1_Click(object sender, EventArgs e)
{
image = new Bitmap(this.dataGridView1.Width, this.dataGridView1.Height);
this.dataGridView1.DrawToBitmap(image, new Rectangle(new Point(), this.dataGridView1.Size));
memStream = new System.IO.MemoryStream();
printPDialog = new PrintPreviewDialog();
try
{
printFont = new Font("Arial", 10);
image.Save(memStream, System.Drawing.Imaging.ImageFormat.Bmp);
image.Save("d:\\Adnan.bmp");
p = new PrintDocument();
p.PrintPage += this.p_PrintPage;
this.printPDialog.Document = p;
printPDialog.Show();
}
catch (System.Runtime.InteropServices.ExternalException ee)
{
}
}
private void p_PrintPage(object sender, PrintPageEventArgs e)
{
float linesPerPage = 0;
float yPos = 0;
int count = 0;
float leftMargin = e.MarginBounds.Left;
float topMargin = e.MarginBounds.Top;
int? line = null;
// Calculate the number of lines per page.
linesPerPage = e.MarginBounds.Height /
printFont.GetHeight(e.Graphics);
e.Graphics.DrawImage(Image.FromStream(memStream), leftMargin, topMargin);
}
private void printPDialog_FormClosed(object sender, FormClosedEventArgs e)
{
image.Dispose();
memStream.Dispose();
}
Problem is my DataGridView has a large list. I have DataGridView inside the FlowLayoutPanel. I tried printing FlowLayoutPanel as well as GridView but in either case the data which is obscure by a vertical scrollbar does not get printed. After spending hours online and trying VB powerpacks I am at loss what to do.
Here is how the data looks in GridView.
