Increase dpi resolution for jqplotToImageStr function

[SEEd Medical Publishers]

Hi,

can I manage the resolution picture for images created with jqplotToImageStr function?

On line I found just this kind of options definition:

var options = {

  x_offset : 20,

  y_offset : 20,

  backgroundColor : "#675423"

};

$('#rasterizedPicture').append($('<img/>').attr('src', $('#vectorialPicture').jqplotToImageStr(options)));

Is there an option about rasterized picture width o dpi resolution?

Thank you,

Enzo
