Can't add a background image

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi,
I'm having problems to add a background image to my pdf. The problem is that the original pdf has a white background/image/filled-rectangle (I don't know wich one is it) that doesn't let me see the image at the back.

Only to make you understand what I'm saying, if the problem were in Word, I could solve it by pressing "Send it to the back" button.

Thank you,

Regards,

Juan D'Angelo

	Hi Juan! Please read in the online reference about Optional Content Groups here: http://www.quickpdflibrary.com/help/quickpdf/ContentStreamsAndOptionalContentGroups.php and try the layer-functions like CombineLayers, DeleteLayer, LayerCount and MoveLayer. With MoveLayer(from as long, to as long) you can push disliked layers to the background. Cheers and welcome here, Ingo

	Hi Ingo! Thank you for your quick reponse. I'm having troubles to find "MoveLayer" command in QP. I've recently adquired the QuickPDFDLL0811.dll version with QuickPDFDLL0811.vb and it doesn't seem to have it... Do you know what can i do? Thank you in advance, Juan F.

	I've read the link. I've figured out the 'layers' are now 'contentstreams'. Now, the problem I have is that I have text and background in the same contentstream... How can i make to separate them?? Thank you, Juan F.

	There is a function called SplitPageText that will split the graphics and text into separate layers. This would be a good start and hopefully will help solve your problem. I have never used this function before. Andrew.

	Andrew, Thank you so much! The function have worked great! If anyone is experimenting the same problem here's the solution: To erase the background and leave only text: QP.LoadFromFile(sourcePDF, "") QP.SelectPage(1) QP.SetOrigin(1) QP.SplitPageText(0) QP.SelectContentStream(1) QP.DeleteContentStream() QP.SaveToFile(sourcePDF) Cya!
