Working in .NET 3.5.
Summary:
Trying to replicate functionality of an existing third party component, which breaks in Windows 7. Until now the user could select a bunch of image files to print, specify a page size for each image and then send them off to print all in one go. I am in dire need of a conceptual explanation of how to go about printing switching the page size on the fly when printing each page.
Details
So far I have figured out how to print multiple images all with the same page size. I use a list of images and use a PrintDocument
object, setting the HasMorePages
property of the PrintPageEventArgs
to true until I reach the end of the list.
Here's a class I quickly threw together to test this:
public partial class Form1 : Form
{
private List<Image> images { get; set; }
private PrintDocument printDocument { get; set; }
public Form1()
{
InitializeComponent();
this.images = new List<Image>();
this.images.Add(Image.FromFile(@"C:\test60.bmp"));
this.images.Add(Image.FromFile(@"C:\SuperLargeTest.jpg"));
this.printDocument = new PrintDocument()
{
PrinterSettings = new PrinterSettings()
};
this.printDocument.PrintPage += printDocument_PrintPage;
}
private void printDocument_PrintPage(object sender, PrintPageEventArgs e)
{
Graphics g = e.Graphics;
e.PageSettings.PaperSize = this.paperSizes[this.currentImageIndex];
RectangleF marginBounds = e.MarginBounds;
RectangleF printableArea = e.PageSettings.PrintableArea;
int availableWidth = (int)Math.Floor(printDocument.OriginAtMargins ? marginBounds.Width : (e.PageSettings.Landscape ? printableArea.Height : printableArea.Width));
int availableHeight = (int)Math.Floor(printDocument.OriginAtMargins ? marginBounds.Height : (e.PageSettings.Landscape ? printableArea.Width : printableArea.Height));
g.DrawRectangle(Pens.Red, 0, 0, availableWidth - 1, availableHeight - 1);
g.DrawImage(this.images[currentImageIndex], printableArea);
e.HasMorePages = ++currentImageIndex < this.images.Count();
}
private void button1_Click(object sender, EventArgs e)
{
this.printDocument.OriginAtMargins = false;
this.printDocument.Print();
}
}
The thing that I really can't figure out is how to go about changing the page size for, say, the second image. If I wanted the first image to print in A4 and then the second one to print on A3, how would I go about doing that?
I found this SO question here which seemed to suggest changing the PageSize
in the PrintPageEventArgs
, but had no joy there.
I also tried to use the QueryPageSettingsEventArgs
event and set the PageSettings
there, but that didn't seem to work either...
What I would like to achieve is print multiple pages of different size as a single document. Any suggestions, links, explanations, sample code would be very much appreciated.
Anything in C# or VB.NET is fine.
