Legacy ImageMagick Discussions Archive

Hi team,
we have a question on if we could expand canvas area of an image in a particular direction.
Here is a screencap of what I’m referring to.

Let us know if there is any command with the ImageMagick scripting. Most importantly is the ability to perform percentage based expansion from a particular anchor point/direction.It would be helpful if you can give a "convert" script for expanding canvas area of an image


The IMM version which we use is ImageMagick-6.6.9-Q16 and the ghost script version is gs9.05. We have a limitation and hence we cannot upgrade the IMM version.
Thanks

This extends the image in the x-direction only, putting the image to the east (the right) side of the new image.

I don't know if this works in v6.6.9.

Hi ,
Thank you so much for the below code is not working
convert rose: -gravity East -extent 120%x100% e.png
unfortunately the command is not working in v6.6.9

can you please give me an command which will work in 6.6.9

thanks

This might work: That is Windows CMD syntax. For bash, escape the parentheses: \( and \).

Hi ,
Thank you for the reply,
both the above mentioned codes are working . I did a mistake by not replacing Rose

however I would want to expand the image on all side
hence I tried the below command and it is working . All the sides has an equal expansion (top and bottom of equal size , and left and right are of equal size ) Is it possible to expand the top more than the bottom and the sides less than the top but more than the bottom.
in other words can we perform mutilple expansion in one command .
Please let me know if the above condition can be acheived

You can do as many operations as you want in a single command, eg:

Thank you so much it is working

You can also use +-X+-Y added to the extent. The + sign moves it up and to the left. The - sign moves it down and to the right.

Compare:
with
The X and Y are always in pixels.
