I'm writing a Linux X selection manager and am trying to handle copying graphics from an X app on Linux and paste it into PowerPoint on a Windows box running in an rdesktop window. It appears that the rdesktop only ever accepts text targets (STRING, UTF8_STRING, ...) and not graphics targets like image/png or BITMAP is this true? Can I use UTF8_STRING to deliver the graphicds data to rdesktop? What form (encoding) does graphics data need to be in to be transfered through the RDP protocol to Windows?
