Here's a quick example showing how to use the image_create and
image_write functions to do what you need.

COMMON Colors, r_orig, g_orig, b_orig, $
r_curr, g_curr, b_curr

;Image types supported
;BMP,GIF,JPEG,MIFF,PCD,PCX,PNG,SUN,TGA,TIFF
imgtyp = 'gif'
imgsz = 400

;display image
DEVICE, pseudo_color = 8
WINDOW, 0, colors = 256, xsize=imgsz, ysize=imgsz
LOADCT, 5
TV,DIST(imgsz)

;write output
graphic = TVRD(0, 0, imgsz-1, imgsz-1)
cmap = [TRANSPOSE(r_curr), TRANSPOSE(g_curr), TRANSPOSE(b_curr)]
iout = IMAGE_CREATE(graphic, Colormap = cmap, File_type = imgtyp)
status = IMAGE_WRITE('test.'+imgtyp, iout, /overwrite)
