javascript - HTML Canvas is rendering text slightly differently accross browsers -

-

i'm developing web application heavily relies upon knowing exact x , y location of each text character on canvas. problem different browsers aren't rendering each character same scale.

the font using courier new, have tested in chrome 9, ff4 beta , chrome 9 beta.

i know if there can done. also, due how browser handles text or purely canvas api?

i remember article interoperability tests between different browsers. handling of fonts different in each browsers. there differences css , weight or rotation in transform. not think able achieve perfect rendering in each of them
