I have some vb code that I am using to try to imposition some pages. It took me forever to figure it out but the drawcapturedpage command is drawing it far off of the current page. are there any known issues with this? Is there something that I am missing?

Here is the code that I am using:

QP.LoadFromFile(SrcFileName, "")

Dim numpages As Integer = QP.PageCount

Dim pagewidth = QP.PageWidth()

Dim pageheight = QP.PageHeight()

MsgBox("There are " & numpages & " in the " & pagewidth & " x " & pageheight & " document.")

Dim ThisCaptureID = QP.CapturePage(2)

QP.NewPage()

'QP.SetPageDimensions(1224, 792)

QP.SetPageSize("Tabloid")

QP.SetFillColor(1, 1, 0)

QP.DrawBox(0, 0, 1224, 792, 1)

Dim Capt = QP.DrawCapturedPage(ThisCaptureID, 0, 0, pagewidth, pageheight)

MsgBox(Capt)

QP.DeletePages(1, numpages)

QP.SaveToFile("newfile.pdf")

QP = Nothing

A PDF origin is the bottom left corner as opposed to the top left as you might intuitively expect.

Try calling QP.SetOrigin 1 to change the origin to the top-left corner before drawing.

So the origin of the source and the origin of the destination are both bottom left? That seems strange. I will give it a shot.

dptulk is correct.

The origin is located in the bottom left corner and the y axis increases as you go up the page. This is the default for Postscript and PDF.

Call QP.SetOrigin(1) just before you call QP.SetPageSize() and it should work well.

Hi,

I see another small problem. You try to delete all pages. Only because of

"PageCount The total number of pages to delete. The value will be automatically adjusted if
necessary so that the document is left with at least one page."

DeletePages deletes only numpages-1. This potential to come in error, when making the code for more than only test.

Cheers,
Werner
