These are questions asked by maple fan

I want to export a figure,

whatever the format I select, for example bmp,

I found that the resolution of that exported bmp file is fixed 400*400,

how can I change the resolution with a command,

because of its precise control,

help me,

thank you in advance.

plots[implicitplot](tan(x*sqrt(cp^2/3220^2-1))*(cp^2/3220^2-2)^2+4*tan(x*sqrt(cp^2/6450^2-1))*sqrt((cp^2/3220^2-1)*(cp^2/6450^2-1)) = 0, x = 0 .. 14, cp = 0 .. 7000, gridrefine = 7, signchange = false),

the command above can't give me the whole figure, it lost some points in [0,3.5(approximation)],

can someone help me,

thank you very much
