Re: eliminating extra space

aha i see, very nice the "-define distort:viewport=125x125-25-25 "
this looks great, so the question now is

in terms of performance what is faster?
to use +distort ?
or to use -define distort:viewport=125x125-25-25 ?

Re: eliminating extra space

thank u very much Fred :)
+ distort seems to work, i just tried it, all i did was to change
-distort to +distort and it works, seems to work,

are there are differences in performance between using +distort and using the viewport solution?

i will now check your link of the viewport solution

Re: eliminating extra space

ahaaa
i see that +distort seems to work now, mmm , nice

what about the alternative anthony says? the
"However you can override BOTH techniques by specifying a expert 'viewport' setting you want to use to 'view' the distorted space."

i would like to do that, sounds like the best of it all

Re: eliminating extra space

Re: eliminating extra space

seems that i can do it by adding at the end

-extent $finalwidthx$finalheight

that seems to work, is that the best way to reduce the final size to the desired one?

thank u very much
