Using Scale [.002083333, .002083333] prior to Image should do the trick.

Alternatively, use Construct to create a 1920x480 grid with space of
.002083333 in each direction.  Then use Replace to use its positions
instead of the original ones.

Subject:    [opendx-users] trouble resizing grid



(Embedded image moved to file: pic23044.jpg)
Hi-

I have a network which slurps in a 1920x480 data series with 90 timesteps.
I feel that my network works reasonably well, but I am having one problem.
When I have it draw the image axes, it uses the array indices. I want to
use real coordinates. That is to say, instead of [1,1]->[1920,480], I want
to have the axes be [0,0]->[4,1]. I have tried applying a transformation
matrix (with Transform) and scaling the axes (with Scale), but the result
seriously degrades the image quality. Is there a better way to do this?

I am applying the scaling after I compute the ln of the matrix, but before
I colorize or rubbersheet it.

Thanks,
Dan
