No because, well, you know, it's IDL :o) Still weird tho'.
I use IDL on linux exclusively (well, sometime on the IBM systems too, but that's
v6.something) and have never seen this behaviour. My startup file looks like:
DEVICE, TRUE_COLOR=24
DEVICE, RETAIN=2, DECOMP=0
WINDOW, /FREE, /PIXMAP, COLORS = -5
PLOT, [ 0 ]
WDELETE, !D.WINDOW
DEVICE, SET_CHARACTER_SIZE = [ 6, 9 ]
PRINT, 'Number of colors is ', !D.N_COLORS
PRINT, 'Color table size is ', !D.TABLE_SIZE
COLORS
COMPILE_OPT DEFINT32, STRICTARR
The only difference I can see is that I issue the DEVICE commands on separate lines. Or
maybe the
DEVICE, SET_CHARACTER_SIZE = [ 6, 9 ]
should always be issued after the
WINDOW, /FREE, /PIXMAP, COLORS = -5
PLOT, [ 0 ]
WDELETE, !D.WINDOW
??
My IDL version:
IDL> help, !version,/structure
** Structure !VERSION, 8 tags, length=76, data length=76:
ARCH STRING 'x86'
OS STRING 'linux'
OS_FAMILY STRING 'unix'
OS_NAME STRING 'linux'
RELEASE STRING '7.0'
BUILD_DATE STRING 'Oct 25 2007'
MEMORY_BITS INT 32
FILE_OFFSET_BITS
INT 64
