In a previous thread i had described a problem i had to transfer a frame or panel and all it's
components as an image into a buffered image. I thought i had found the solution but it seems i am doing something wrong. In line 162 i call the method Bimage(lines 87 - 92) to do this job.But what i get is just the background of the panel and not what is drawn on it.I used try { ImageIO.write(bimage, "jpg", new File("C:/bimagepaint.jpg")); } catch (IOException e){ } to find out what this method produces. Any suggestions?
