There can be different reasons for that. Did you read the second edition of "iText in Action"? Chapter 3 gives you one possible reason (you added the image UNDER existing content); chapter 5 gives you another one (you added the image outside the visible area of the page). > My questions are : > > 1. How can i find out invisible images embedded in pdf using iText api. Extracting images is explained in chapter 15. You get the X,Y coordinates, so you can check if the image is outside the visible area, but AFAIK you don't get the Z-order, so you can't tell if the image is overlapping with other content. > 2. what are all the possible reasons for image gets invisible in pdf.

You can extract some images (not all!) with iText 5.x.y. > Any way to make invisible image to visible by programatically. You should add them correctly right from the start.

Ouch, forget everything above: we don't support that version here. -- This answer is provided by 1T3XT BVBA http://www.1t3xt.com/ - http://www.1t3xt.info ------------------------------------------------------------------------------ Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing. http://p.sf.net/sfu/novell-sfdev2dev _______________________________________________ iText-questions mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/itext-questions Buy the iText book: http://www.itextpdf.com/book/ Check the site with examples before you ask questions: http://www.1t3xt.info/examples/ You can also search the keywords list: http://1t3xt.info/tutorials/keywords/
