Possible bug in MAP_PROJECTION of an image 1188 1
Started by Deleted User
Hello,
When using IMAGE() with the MAP_PROJECTION and GRID_UNITS properties set, the first row and column of my image are ignored. Is this a bug, or some subtlety of map projection that I'm missing
Cheers,
A
e.g.
;; Define an image
im=BINDGEN(3,5,4)*21b
;; And plot it normally
i0 = IMAGE(im,AXIS_STYLE=2,IMAGE_DIMENSIONS=&91100,80&93,IMAGE_LOCATION=&91-50,-40&93,LAYOUT=&912,2,1&93)
;; Now add GRID_UNITS=2 to define lat/lon and MAP_PROJECTION keywords

geometry_doit not working 1255 2
Started by Deleted User
Hi, I am trying to develop a script which will obtain AVHRR sensor viewing angle. In ENVI this would be the AVHRR Geometry tool. Unfortunately I run into error messages when I try to automate this in IDL using the envi_avhrr_geometry_doit command. Specifically the error states: 'Variable is undefined: WL' however the 'WL variable is not explained within the tool documentation.
I am fairly new to IDL scripting so I am sure I am making a simple mistake somewhere but any advice you can offer would...

Plotting a symbol on a logged scale 1319 3
Started by Deleted User
Hello,
I am having problems overplotting a symbol on a plot that has a logged axis. For example, when I use the commands below, the symbols are not placed in the appropriate position (I tried uploading my example plot, but I received a permissions error). I would like to put a symbol at the &912,2&93 position, but that particular symbol is outside of the graphics domain. It is also unclear why the 0.1, 0.2 & 0.5 symbols are on the plot when they are not within the X and Y range of the plot....

Local Minima/Maxima 1062 2
Started by Deleted User
Is there an IDL method for finding local minima/maxima within an image Or something akin to morphological reconstruction (greyscale) whereby local minima and maxima can be derived
The watershed function mentions local minima, but for better results use markers, which comes back to a method of automatically finding those markers ie the local minima.
Cheers
Josh

COLORBAR 1171 2
Started by Deleted User
Hi,
I'm having some problems with COLORBAR. The code segment below worked fine in v8.2 in generating a colorbar with a discrete number of tick labels. In 8.3, however, the number of tick labels is the same as n_levels in the contour command. This is problematic when there are a large number of levels. The MAJOR=n command in colorbar doesn't seem to work. Any help would be much appreciated.

New Graphics routines compatibility with Direct Graphics windows ? 1230 3
Started by Deleted User
Hello,
Is there a way to use a *new graphics* (NG) function (such as BARPLOT) within a *direct graphics* (DG) window
For example, BARPLOT (NG) has some useful new features such as N_BARS parameter which doesn’t have BAR_PLOT (DG), but NG are too bandwidth consuming to use IDL from a remote computer (through sshX11).
Thanks,
Guillaume

scatter plot between two images 1352 1

I have two images of size 2000x2000 pixels with 16-bit data range (values in the image going upto 65534).
I have a logic for scatterplot which requires a 2 dimensional array of size (65534,65534) which doesn't seem to work.
What is the way out
