[opendx-users] trouble resizing grid

[Daniel J. Patnaude]

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
