Please, have a look at the 2 pdf file (link below), one is source another is output, when i use objPDF.DrawText(450.584, 43.453, "I love to test"), and check the output file, the text get vertically flipped? i don't found any function that can change the text orientation and also why by default text get flipped?

Not only text, even when i tried to use draw image, it also flipped.

Here is the links for the files:

Hi Salma,

this will have to do with rotated syntax in the pdf source.
Before you're using the drawing functionalities.
You should set a "CombineContentStreams":
http://www.debenu.com/docs/pdf_library_reference/CombineContentStreams.php
and a "NormalizePage":
http://www.debenu.com/docs/pdf_library_reference/NormalizePage.php
Then you'll get what you want ;-)

Cheers and welcome here,
Ingo

BTW: Here's nothing ASAP 'cause this is a user-user-forum but here are friendly, helpful users ;-)

hi, first of all thanks a lot for being so helpful and reply. And Then i am very sorry for the "ASAP" words, as i was stuck and on hold that's why i used that term.

btw. sir, i have another question how do i know in prior to processing a PDF file that it has something wrong in it? so, i can call the combine and normalize command before processing? or is it safe to run that command on all PDF before any kind of processing?

once again thanks

best regards

If you want to draw anything onto a pdf-page you should do at least the NormalizePage first.
If you want to extract anything from a pdf-page you should  do at least the CombineContentStreams first.

Ingo
