Image from bytes streams

First, thank you very much for the answers... I have used the png() function before for generate the image and then capture its bytes. My big problem is that my program reads the image before that its complete by the png() function. For instance, my graphic image has 1000Kb. When R saves it into the hard disk, my Java program reads the file before the save operation completes (500Kb for example). So, I got only a part of the file and hence the image... :( One solution is read the image and search for a byte which represents the end of the file, but it depends on the image format... So, how can I discover that R image save operation stored the complete file into the hard disk?
When dev.off() completes and you get an R prompt back.
