Following the ideas, I get:
function rescale(img)
h=height(img)
w=width(img)
scale_x = 2
scale_y = 2
new_h = int(h*scale_y)
new_w = int (w*scale_x)
A = data(img)
Ai = InterpGrid(A, BCnil, InterpNearest)
new_image_data = reshape(1:(new_h*new_w), new_w, new_h)
for col = 1:new_w
for row = 1:new_h
new_image_data[col, row] = Ai[div(col,scale_x), div(row,
scale_y)]
end
end
new_image = InterpGrid(new_image_data, BCnil, InterpNearest)
end
with InterpGrid giving me an error:
julia> rescale(img)
ERROR: InterpGrid not defined
in rescale at none:9
I tried updating by Pkg.update() because of this issue.
