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: https://www.dropbox.com/s/d5i0ekn91zq7frd/Source.pdf?dl=0 https://www.dropbox.com/s/ycp16e7tgp6u6o9/Output.pdf?dl=0 https://www.dropbox.com/s/9stmnuycajg5wnr/Output.png?dl=0 please sir, leave a reply asap thanks in advance |

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 ;-)
------------- Cheers, Ingo |

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. ------------- Cheers, Ingo |
