Confused about image dimensions [message #91075]

Hi,
maybe I'm missing something very basic...
Suppose I make an image with these commands:
w = window(dimension=[600,600])
i = image(dist(600), margin=0, image_dimensions=[100,100], current=w)

The idea is that the image has 600x600 pixels, but the units are 100x100.
So each pixel (device units) has a size of 6.

If I now change the data:
i.setData, dist(300)

It turns out that the "image does not change" (in appearance) and not the 300 pixel correspond to 100 units. So that the pixel has a size of 3 units.

Can I redefine, after the setData, the image_dimensions?

I did notice that the "image_dimensions" keyword is under the "Keywords are applied only during the initial creation of the graphic." part of the help. Just looking for a way around this.

Thanks,
Helder
