Re: [jzy3d] java.lang.IllegalArgumentException when trying to screenshot

[Martin Pernollet]

Hi Deepak,

To create your screenshot, you must have the chart already displayed. So first:

ChartLauncher.openChart(chart, new Rectangle(0,0,600,600),"Test");

and then:

ImageIO.write(chart.screenshot(), "png", new File("d:/test2.png"));

If you want to do offscreen image generation, you have to dive into the - non-working - net.masagroup.jzy3d.plot3d.rendering.canvas.OffscreenCanvas

that relies on

GLDrawableFactory.getFactory().createGLPbuffer

Hi Martin,

 

Thanks alot to you and your team. Good Job .

 

My client is happy with the plot, he appreciated the work. But I'm still trying to make it better. If require I'll definitely bother you. :)

 

I'm expecting new version from JYZ team very soon. :)
