hi and good day :) quick question, what is the most efficient way to do a cylindrical distortion? so i have a flat picture and i want to project it in perspective on a cylinder? the operation should combine the cylindrical distortion with perspective at the same time, i know how to do the perspectiv...

by the way, i believe in recognizing good things when i see them, and i have to say again, i have never in my life seen a forum that works as well as this one, i think the work Anthony and you are doing helping people here is extraordinary, you guys always answer so fast and so well, im really amaze...

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 ?

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

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 s...

thank u very much Fred the extent is working already, not a problem anymore the big problem i have now is that the image im distorting is being cropped by its own boundaries, im trying to understand anthony's explanation of how to allow the distortion to go beyond the image's own boundaries, do u kn...

i just saw this by Anthony so should i use + distort instead of -distort? i tried but nothing seemed to happen, and how do i "specifying a expert 'viewport' setting you want to use to 'view' the distorted space" ? i can see that i need some way of telling the system to apply the distort wi...

i can now explain better my confusion lets say my image has dimensions 680x952 if i use these points in perspective distorsion $p1="0,0";$p2="680,0";$p3="680,952";$p4="0,952"; $w1="0,0";$w2="680,0";$w3="680,952";$w4="0,952&qu...

hi my friends in a command that uses ' -matte -virtual-pixel transparent -distort Perspective' within a larger canvas i dont understand well how the point numbers work, they seem to behave in a peculiar way, if i understand well, those numbers map how each of the 4 corners of the picture move, where...

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

Dear friends in a command where i make a perspective distorsion over another image, extra white space is created in the resulting image, how can i eliminate it within the same original command? $command= 'convert '.$source1.' ( '.$source.' -matte -virtual-pixel transparent -distort Perspective "...

uff it works now in linux i needed to add the \ special character before the ( and ) :) so final question i see it takes a while, is there any other faster command? or this is the fastest? i mean, its fast :) but just wondering if this one is the fastest? $command =$magic.' '.$source.' -matte -virtu...

question

it works in windows with 6.7.0-6
but it doesnt work in linux with 6.6.8-5

is this a problem of the version? or of the syntax?

thank u

ah, magic of imagemagick
it works now, its just all matter of formatting, quotes etc
ay ay ay
thank u my friends

so this is the best command for perspective isnt it? seems quite fast, any other recommendation?

smiles
