Map&39;s xrange and yrange problem? 1351 2

Adding color using Image() 1255 3
Started by Deleted User
Hi,
I have a 2-d histogram that I am plotting using im1=IMAGE(hist, ...). Is there a way to add color to the image so the histogram is colored rather than black&white I've tried things like color=color, /color, n_colors etc. but haven't had any luck. (as a side note I can't seem to get background_color to work either...)
I can get a color plot using the older image command. imdisp,hist, ....
SET_PLOT, 'PS'

object assignment with pointers 1117 0
Started by Deleted User
Many times, I need to create objects with fields whose size is unknown until the time of construction or later. To accomplish this, I leave those fields as ptr_new() until I know what size arrays I need. I know that we cannot overload the assignment operator, but copying each element field for field breaks encapsulation, as changing one class can alter the contents of multiple classes.
Is there any way around this How can I prevent this from happening
Thanks for any help

I should say that I am not sure if this is a true tiff file. this being said the file extension is .tif and I can open it in ENVI.

Orientation of text and title with Plot3D 1223 1
Started by Deleted User
Hi, in IDL 8.2.2, the title and any TEXT objects applied to a Plot3D object would stay fixed in orientation relative to the 3D plot as I rotated the plot with my mouse (their orientation would rotate with the plot). Now, in IDL 8.2.3 the title and text seem to be fixed in orientation relative to the viewer. I can't find how to restore the previous behavior. How can I do this
Thanks.

map LIMIT in function graphics routine 1215 2
Started by Deleted User
Hi,
I am trying to use IDL's (8.2.3) function graphics for displaying projected imagery and vector data. I am using Albers EA projection with standard parallels between 25 and 0 degrees latitude. The geographic area I am trying to display ranges from -10d lat to 30d lat. However, IDL displays map grids and continent outlines below 0 degree lat only if I lower the second standard parallel. My guess is that IDL uses the standard_par2 as the southern map boundary, which would be an incorrect assump...
