问题描述

如何在Java servlet上呈现Processing.org图像？

How to render Processing.org images on Java servlet?

我的scala代码是：

My scala code is:

class Image extends PApplet {
  override def setup {
    size(200,200)
    background(0)
  }

  override def draw {
    stroke(255)
    line(10,10,50,50)
  }

  def renderImage = g.getImage

}


class ImageServlet extends HttpServlet {
  override def doGet(request: HttpServletRequest, response: HttpServletResponse) {

    response.setContentType("image/gif")

    val os: OutputStream = response.getOutputStream
    val image = new Image

    javax.imageio.ImageIO.write(image.renderImage.asInstanceOf[RenderedImage],"GIF86", os);

  }
}

推荐答案

我刚刚发布了一些示例代码这里，听起来它也可以解决你的问题，看一看。它是Java，而不是Scala，但转换应该是微不足道的。

I've just posted some example code here, which sounds like it would solve your problem too, take a look. It's Java, not Scala, but the conversion should be trivial.
