[julia-users] ERROR: invalid base 10 digit '.' in "101.1" ?

[Andreas Lobinger]

Hello,

it might be, i'm trying something strange here, but ...

julia> using Cairo

julia> c2 = CairoRGBSurface(100,100)
CairoSurface(Ptr{Void} @0x0b4959c0,100.0,100.0,#undef)

julia> c1 = CairoContext(c2)
CairoContext(Ptr{Void} @0xb3305500,CairoSurface(Ptr{Void} 
@0x0b4959c0,100.0,100.0,#undef),Ptr{Void} @0x0c5bf840)

julia> move_to(c1,100,100)

julia> move_to(c1,100.5,100)
ERROR: invalid base 10 digit '.' in "100.5"

and yes, according to Cairo.jl the call seems to be:

     @eval begin
        $NAME(ctx::CairoContext, d0::Real, d1::Real) =
            ccall(($(Expr(:quote,FUNCTION)),_jl_libcairo),
                  Void, (Ptr{Void},Float64,Float64), ctx.ptr, d0, d1)
    end

so something with float.

Wishing a happy day,
     Andreas
