I think I see the problem. 3800 x 3800 x 4 = 57 MB. JUMP uses image buffers for large layers, one for each layer with over 100 features, plus there is Swing double buffering. So if you had 3 large layers, it would take over 400 MB just to draw the image. For 6 it would almost 800 MB. I was abl

I'll need more details in order to reproduce the problem. The raster layers in OpenJump are probably the issue. SkyJUMP supports only a few raster implementations that we have coded ourselves. OpenJump supports many different, each with their own advantages and disadvantages. Try it with only v

Hi all and Larry, I tested the new "export view to Image" with the new implementations to set the resolution. I tried to exporte an image (with raster and vectors layers) with the maximun resolution 3800, both with OpenJUMP and SKyJUMP and compare the time and the output. After a good 60 secon
