I use the RenderDocumentToStream function to render the following file and it returns a blank page.
The output is in jpg and the resolution is set to 96dpi. a) http://tinyurl.com/yzusfvm b) http://tinyurl.com/yglpkdh KK Aw |

Hi!
You should try the very latest version. For me (my test-app) rendering works. Perhaps you should post your code (a snippet) here... Cheers, Ingo |

I am using the latest version.
The codes that I use are as follows: QP := TQuickPDF0717.Create; {Memcheck} myStream:= TMemoryStream.Create; try QP.unlockKey('...Insert License Key Here...'); QP.LoadFromFile(aSrcFileName); Qp.RenderPageToStream(75, 1, 1, myStream); myStream.Position:= 0; myStream.SaveToFile(FSrcFileName); finally QP.Free; myStream.Free; end; I am rendering hundreds of pdf files but a few of them like the sample I gave generates blank images.

Ugh! Ingo better take out KK's unlock key from his message or it will make it harder to sell the library in the future.

Thanks Jack -- I've removed the license key, luckily it was only a trial license key.

My apologies.

"...

Be happy that the very most of your pdf-documents will be rendered fine? ...or sending the few pdf-files with a detailed description regarding the problems to the official support pages. For this case i've posted a thread in the general section (the first steps...). Cheers, Ingo |

I have submitted two cases to the official support pages (1548 and 1558) more than a week ago. So far I have not got any response. A possible cause is that the font type used is "unnamed" and this is extract from another PDF file using PDFCreator.

Hi!
If you don't get a response 'till now post it there (Debenu) and not here. This here is only a user-user-forum ;-) Again: I've made some tests with my test-app. Preview/rendering works. Textextraction works, too. If there's something wrong then it should have to do with your local system. Try it on a nother machine... it will work - i'm pretty sure.
