Here is my code:
im1=image(big_img,dimensions=n_elements(big_img[*,0]),n_elem ents(big_img[0,*])],window_title=slitname+'-+filtername,max_ value=highval,min_value=lowval,margin=[0,0,0,0],location=[0, 0],/xstyle,/ystyle)
I've explicitly given it dimensions, margin, and location. I even threw in xstyle and ystyle for good measure. It seems like there is always HUGE white space above and below my actual image. Its never in the x direction, only in the y direction.
This is an issue because I want the exact location on the image where someone clicks and if there is whitespace
I'm on mac os 10.8 if that changes anything.

Well, let's begin with the fact that the line of code you gave is full of errors... that said, this works fine for me:
big_img = dist(512)
mx = max(big_img, min=mn)
im1=image(big_img,dimensions=size(big_img,/dimensions),windo w_title='title',max_value=mx,min_value=mn,margin=[0,0,0,0],l ocation=[0,0],/xstyle,/ystyle)
> I'm on mac os 10.8 if that changes anything.
Don't know about the mac, but maybe the idl version counts.
IDL> !version
{
ARCH: "x86_64",
OS: "Win32",
OS_FAMILY: "Windows",
OS_NAME: "Microsoft Windows",
RELEASE: "8.3",

MEMORY_BITS: 64,
FILE_OFFSET_BITS: 64
}
Cheers,

I see no whitespace with this square image, but try it with
big_img = findgen(1000,100)
mx = max(big_img, min=mn)
im1=image(big_img,dimensions=size(big_img,/dimensions),windo w_title='title',max_value=mx,min_value=mn,margin=[0,0,0,0],l ocation=[0,0],/xstyle,/ystyle)
This makes a rectangular window with whitespace at the top and bottom.
my IDL version
{ x86_64 darwin unix Mac OS X 8.2 Apr 10 2012 64 64}
Hmmm. Is it a factor if I'm using the idlde? It seems to show a window with no whitespace when run from the command line, but there is whitespace when I'm using idlde.... Is there a way to fix this?

The code from Helder works fine for me in idlde, no whitespace. OS 10.9.2.

Helder's code also worked with no whitespace for me, but the problem seems to happen with long rectangular images. Did you try it with big_img = findgen(1000,100) ?

Sorry, I missed this. But your big_img does work fine, i.e., no whitespace, for me as well.

Just to chime in, I think in IDL 8.3 and earlier, there was a hardcoded limit on the X and Y dimensions of the window. For the X dimension it was something like 450 pixels, while for Y it was 50 pixels.
If you are still having problems, you might try adding the /WIDGET keyword, to force IDL widgets instead of Java SWT widgets.
Also, even if you do end up with whitespace, why can't you use the ConvertCoord method to determine if the mouse click location is on or off the image?

Same version of IDL that Philip is using, and without having any windows
open, this code produces a window with white space top and bottom:
big_img = dist(512, 248)
mx = max(big_img, min=mn)
im1=image(big_img,dimensions=size
(big_img,/dimensions),window_title='title',max_value=mx,min_ value=mn,mar
gin=[0,0,0,0],location=[0,0],/xstyle,/ystyle)
It is as though the image refuses to give up its image aspect ratio.
Cheers,
David

I think the /widget keyword is doing what I want. I also noticed a slight difference in the appearance of the windows using idlde and just idl from a command line. it looks like running it from a command line automatically opens it up as a widget.
The convert_coord function would work, but another issue is that some people using the software have much smaller monitors than I do, and the images are taking up much more space, which ends up being a problem itself sometimes :)

I can just instruct everyone using this software to not resize the windows... problem solved, right?
Though the whitespace was more of a "taking up too much monitor space" or (for people with large monitors) an aesthetic issue, really.

The program cgCmdWindow (cgWindow is a wrapper for this program) is
already set up for handling widget events. You simply need to write your
own event handler for the program, tell it what events you want it to
handle (button events, for example), and off you go. It is incredibly
simple and simple-minded. Probably why it works so well. ;-)
You don't program it with "handlers", rather you just respond to the
events themselves. Widget Programming 101, really.
If you didn't want to do it yourself, it might take 15 minutes for me to
code something up for you. The program cgCmdWindow is basically a draw
widget that knows how to "execute" IDL graphics commands that are added
to it. Commands like cgImage.
Cheers,
David

I probably need to take Widget Programming 101 :) I'll look into this, but I think for now, its best to stick with what I know works.
