Happy New Year to all of you
Does anyone try to split an A3 page to A4 pages.
Page contains roughly 10 images, so could not use the graphics facility to split pages.
So any help/advice will be welcome
Thks in advance

Hi!
Copy the A3-page to an A4-page.
Rotate the A3-page with 180 degree.
Copy the A3-page to another A4-page.
Rotate the other A4-page with 180 degree.
...It's only from my mind... should work ;-)
More details... here's the online-reference:

Ingo,
Thanks for you reply & your welcome message.
Copypageranges does not work (documentation is very poor abour this function, especially using .net) , may be due to usage of DAFileOpen.
I found some differences depending on using DA or "normal" functions. Is there any datasheet on impact when using one or the other, and when to choose DA functions or "normal"
Still investigating ;-)

Hi Eric!
The MOST important thing:
Don't (NEVER) mix DA-functions with non-DA-functions!
Cheers, Ingo

Ingo,
Thanks for your advice, i will ;-)
Till now, i forgot CopyPage which does not work, and use Extractfile (which allows also to make a work copy more safe)
Then i used your rotation advice, it works for the left page but not for the right one (it stilll got the left page)
Please find below an code extraction (i'm convinced this is an obvious but looking for too long)
Feel free if u see where i'm wrong
Thks in advance

zPdf.LoadFromFile("c:\temp.dir\blank_pp1.pdf")
lRtn = zPdf.RotatePage(90)
lRtn = zPdf.SetPageSize("A4 Landscape")
lRtn = zPdf.SaveToFile("c:\temp.dir\blank_pt1.pdf") >>> Left page is ok
'
zPdf.LoadFromFile("c:\temp.dir\blank_pp1.pdf")
lRtn = zPdf.RotatePage(180)
lRtn = zPdf.SaveToFile("c:\temp.dir\blank_pp2.pdf") >>>> right page is at the bottom
zPdf.LoadFromFile("c:\temp.dir\blank_pp2.pdf")
lRtn = zPdf.RotatePage(270)
lRtn = zPdf.SetPageSize("A4 Landscape")
lRtn = zPdf.SaveToFile("c:\temp.dir\blank_pt2.pdf") >>>>> left page but inversed

Ingo,
I solved it using graphics function (renderpagetoDC) and then using .net image manipulations.
It seems that using the rotatepages function keeps height and width to the original values (before rotation) .... easy to fix, but little bit boring ...
thks for your help

Eric
Ps : how to close this post
