Can we set the image size in pixels?

[hmf]

I would like to set the image size in pixels.
I tried this but it does not work.

    val bufferedImage = plot
      .xAxis()
      .yAxis()
      .frame()
      .xLabel("x")
      .yLabel("y")
      .render(Extent(800, 600))
      .asBufferedImage
    ImageIO.write(bufferedImage, "png", file1)

Is this the correct way to do it?

As an update, I looked at the code and cheated by using .render(Extent(800/4, 600/4)). So the image size is sort of ok (853 x 600) but the scaling is off. I get the image below:

So Extent seems to be for image size, but something seems to be wrong.

BTW, using version 0.7.0

Full code below:

    import com.cibo.evilplot._
    import com.cibo.evilplot.plot._
    import com.cibo.evilplot.plot.aesthetics.DefaultTheme._
    import com.cibo.evilplot.numeric.Point
    import com.cibo.evilplot.geometry.Extent

    import better.files._
    import File._
    import java.io.{File => JFile}
    import javax.imageio.ImageIO

    val data = Seq.tabulate(100) { i =>
      Point(i.toDouble, scala.util.Random.nextDouble())
    }

    val plot = ScatterPlot(data)

    // Supported out of the box: JPEG, PNG, GIF, BMP and WBMP
    val property = "java.io.tmpdir"
    val tempDir = System.getProperty(property)
    val file1 = Utils.temporaryFile(tempDir, "_evilplot.png").toJava
    val bufferedImage = plot
      .xAxis()
      .yAxis()
      .frame()
      .xLabel("x")
      .yLabel("y")
      .render(Extent(800/4, 600/4))
      .asBufferedImage
    ImageIO.write(bufferedImage, "png", file1)

    file1.getPath
