Hi All, I am looking for a way to resize all pages of a pdf (containing some A1, and some A0 pages) to A4.

I have experimented with:

SetPageDimensions

NormalizePage

DrawCapturedPage

but no luck yet.

Any help would be appreciated.

Did you use CapturePage or CapturePageEx ?

can you post code snippet ?

CapturePage/CapturePageEx should not matter unless the input file mediabox is the wrong size. 'Ex' allows you to use a choice of boxes for capturing.

I would do something like the following to resize to A4:

// First find out how many pages you need to process:
inputDoc=LoadFromFile(documentname,password)
pagesToProcess = PageCount()

// Create your "sized" template with the correct number of pages
sizedDoc = NewDocument()
SetPageSize("A4")
InsertPages(pagesToProcess -1   // We got one page "for free"

// Combine the documents so CapturePage can be used
MergeDocument(inputDoc)            // Append the document so CapturePage can be used
currentPage = 1
while (currentPage <= pagesToProcess)
{
CapturePage(pagesToProcess+1)   // This deletes the page from the document
SelectPage(currentPage)
DrawCapturedPage(0, 842, 595, 842)    // This draws the captured page at A4 size regardless of its original dimension
currentPage += 1
}
SaveToFile()

I think you are using this:

DrawCapturedPage(0, 842, 595, 842)

in a wrong way.

I see you are using default value for SetOrigin

so I think you need to use this:

DrawCapturedPage(0, 0, 595, 842)

Doc for DrawCapturedPage says left, top, width, height.

DrawRotatedCapturedPage uses left, bottom, width, height, angle

I think my numbers are correct.

I see you are using

DrawCapturedPage

not

DrawRotatedCapturedPage

EDIT:
ah I see

SetOrigin default is 0 = Bottom left (default)

try to change 1 = Top left

and then

DrawCapturedPage(0,0,...

btw.

From Reference guide:

DrawCapturedPage

Top >> The co-ordinate of the top edge of the destination area

I think this is independently your SetOrigin settings.

If I'am right, then I submit request to Debenu for more clearly describe this in the documentation.

I have not tested the SetOrigin, but I do believe you are correct in stating it does not affect the values for DrawCapturedPage.

In any case, I think CrazyTim can get his job done with this information and a minimal amount of experimentation. Good luck!

Thanks guys, DrawCapturedPage(0, 842, 595, 842) was what I needed.

Nice to hear You solved a problem.

Can you use GetOrigin() to say us which Origin you are using just before using DrawCaptredPage.
