Hi
I have a 3D image with the following dimensions Im=[136,136,160]=[x,y,z].
I wanted to display only one pixel from x-direction i.e. Im2=[40,136,160].
I used the cgimage like this:
Im2 = reform(Im2[40,*,*])
cgdisplay, 200,200
cgimage, Im2
The image displayed is 2D. The x-direction was y-direction and y-direction the z-direction in 3D case.
Is it possible to revise the x- with y-direction when I display the image? OR in 3D sense the y- with z-direction.
Can anyone help with this?
Thanks

You probably want the TRANSPOSE() function
IDL> im = bytarr(30,24,88)
IDL> im = transpose(im,[1,0,2]) Switch first and second dimensions
IDL> help,im
IM BYTE = Array[24, 30, 88]
