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=[100,80],IMAGE_LOCATION=[-50,-40],LAYOUT=[2,2,1]) ;; Now add GRID_UNITS=2 to define lat/lon and MAP_PROJECTION keywords i1 = IMAGE(im,AXIS_STYLE=2,IMAGE_DIMENSIONS=[100,80],IMAGE_LOCATION=[-50,-40],$ LAYOUT=[2,2,2],/CURRENT,GRID_UNITS=2,MAP_PROJECTION='Geographic') ;; The problem is also here for sinusoidal (and all other grids) i1 = IMAGE(im,AXIS_STYLE=2,IMAGE_DIMENSIONS=[100,80],IMAGE_LOCATION=[-50,-40],$ LAYOUT=[2,2,3],/CURRENT,GRID_UNITS=2,MAP_PROJECTION='Sinusoidal') ;; Fix the issue by padding the original array im_ = BYTARR( SIZE(/DIM,im)+[0,1,1])*0b + 255b im_[*,1:*,1:*] = im i3 = IMAGE(im_,AXIS_STYLE=2,IMAGE_DIMENSIONS=[100,80],IMAGE_LOCATION=[-50,-40],$ LAYOUT=[2,2,4],/CURRENT,GRID_UNITS=2,MAP_PROJECTION='Sinusoidal')
