I'm trying to copy panel contents to an image I'm using the following code and the string "blah" gets drawen on the image. When I try and paint the image back onto the panel it paints an image with the same color as the panel background and also the text "blah" The thing is I drawlines onto the panels graphics in another procedure but it doesn't seem to copy those lines to the image. Anyone know why???
This is how I call the .drawline() I send drawLine the Graphics i want to draw onto ie. tPanel.getGraphics() I don't fully understand what all the sin and cos maths are for but it works. I got this code from my sample API for smartboards (electronic whiteboards) I want to be able to copy these lines that i draw into an image so i can redraw it back onto the panel with an alpha channel and then still be able to draw on the panel with the smartboard.
