Unable to create XPS doc with A5 pages
I've been bashing my head against this on and off for days and finally accept defeat! How do you save or print items from an ItemsControl to an A5 page with a transform to fit the page?
I have 2 separate problems (I think):-
1) The XpsDocument ignores the PrintTicket and defaults to something like NorthAmericanLetter.
2) The items I'm trying to print are part of an existing visual tree. How can I scale and translate an item when writing it to the document without affecting what is currently rendered to the user?
This is the code I'm using:-
publicvoid SaveItems(ItemsControl ic,String fileName)
{
LocalPrintServer ps =newLocalPrintServer();
PrintQueue pq = ps.DefaultPrintQueue;
// Set the media size.
PrintTicket pt = pq.UserPrintTicket;
pt.PageMediaSize =newPageMediaSize(PageMediaSizeName.ISOA5Rotated, 794, 559);
// Set margins
constdouble cm = 96 / 2.54;
double xMargin = 1.25 * cm;
double yMargin = 1 * cm;
Double printableWidth = pt.PageMediaSize.Width.Value;
Double printableHeight = pt.PageMediaSize.Height.Value;
Double xScale = (printableWidth - xMargin * 2) / printableWidth;
Double yScale = (printableHeight - yMargin * 2) / printableHeight;
//Create package
Package package =Package.Open(fileName,FileMode.Create,FileAccess.ReadWrite);
XpsDocument doc =newXpsDocument(package);
XpsDocumentWriter writer =XpsDocument.CreateXpsDocumentWriter(doc);
VisualsToXpsDocument collator = writer.CreateVisualsCollator(pt, pt);
ItemContainerGenerator gen = ic.ItemContainerGenerator;
collator.BeginBatchWrite();
for (int i = 0; i < ic.Items.Count; ++i)
{
UIElement element = gen.ContainerFromIndex(i)asUIElement;
if (element ==null)continue;
Transform t = element.RenderTransform;
element.RenderTransform =newMatrixTransform(xScale, 0, 0, yScale, xMargin, yMargin);
collator.Write(element, pt);
//element.RenderTransform = t;
}
collator.EndBatchWrite();
doc.Close();
package.Close();
}
The resulting pages are something like 11 x 8.5 inches and the UIElements haven't been scaled or translated (though they are in the UI).
I've been through the SDK samples but they don't really provide any clues. They create visuals which aren't part of the visual tree and use the default page size.
Hoping someone on the XPS team can help.
Thanks
