Array Operations

You can operate on an AstroImage like any other Julia array:

using AstroImages

img = AstroImage(randn(10, 10))

Indexing

You can look up individual pixels (see Conventions):

img[1, 1] # Bottom left

-1.274098479818098

img[1:5, 1:5]

Broadcasting

AstroImages participate in broadcasting as expected:

@. img + img^2 + 2img^3

You can update them in-place (if the underlying array you passed supports mutation):

img[1:5, :] .= 0
img
