SOS: EPS file generated with 'PS' divice 1243 0
Started by Deleted User
It seems that the defauld DPI of 'PS' device is 1000, however a plots with xsize 7 inches and ysize 3 inches is only 18.Mb under bits = 8
So it should not be a bitmap, but also should not be vector graphics as it is too large than as expected.
My question is How can I control the memory cost of a EPS file generated by 'PS' Such a eps plots generated by MATLAB is only 30 kb.

Q: X-Platform GUI 953 0
Started by Deleted User
Hi, i'm just wondering if there are any good reference materials that discuss the difference between (in my case) windows vs linux gui/resize. My ui works perfect on linux and displays correctly on windows for the most part except it doesn't resize correctly (for example doesn't stretch to fix screen size). Differences between draw_xsize, scr_xsize, xsize that kind of thing, which to use and when. The program i'm working on looks exactly as its supposed to on linux, there are a few layout issues...

Multi-Array comparison 1105 1

Multi-Array comparison
Hello everybody,
I have three fltarr(460,483) and I would like to compare them, finding for each element i,j of the arrays which one among the three guarantee the maximum value. However, since I just need to know a sort of 'best server' index, I'm looking for the percentage so finding the total amount will be enough. I've found out the WHERE function, but in my case (three or more arrays) should I make a loop Any ideas
Thanks,
Giuseppe

Hello all,
