Dear All,
The sample of code below is supposed to convert some data to an IDLgrROI
and then display it. The STYLE=0 keyword is supposed to cause the object
to be rendered as a series of points.
This works well when I am connected to the workstation through a VNC
session; however when working directly on the machine's console, it
appears that the STYLE keyword is ignored, and the object is rendered as
though it were a IDLgrPOLYLINE.
Does anyone what would cause this behavior? I am somewhat new to object
graphics, but am learning quickly.
Thanks,
Bill
orois = objarr(num_rois)
for i = 0, num_rois-1 do begin
tmp = (*ptr_seeds[0])[i]
// *tmp is [ n x 3 ]
orois[i] = obj_new('idlgrroi', $
[ transpose(*tmp) ], $
style=0, $
thick=4, $
color=[0, 255, 0], $
alpha_channel=.4)
endfor
omodel->add, orois
xobjview, omodel

Unfortunately ImageShack can't send rightih2.png. The server it is
hosted on seems to be having problems. But...

It most likely is. A simple test would be to explicitly set your
window to use the software renderer. If it renders correctly to the
local screen then you know it is an issue with the video adapter/
drivers.
What OS/distro? Who makes the graphics adapter?
