Convolve shaved a few seconds but not enough. Thank you for your help I will start looking into some of the other options discussed here.

I am noticing convolve treats things a little differently, as a weighted sum. I would imagine this would be faster than "Dilate" because it is performing an operation on every opaque pixel. Also didn't expect the non IM ref for the library :) Thanks Fred(@fmw42), let me see how convolve works first.

I may have a better time integrating it in python. There is a intermediary step I can hook into to achieve my goal. There are a few options it seems, would there be a official library for python that can tackle this type of editing granularity?

The primary leg of the time comes from the "morphology" kernel. I am wondering if creating my own kernel could speed things up?

That is much quicker @snibgo and the shape output is identical to that step, it took 24 seconds . Thank you very much! This is a monumental improvement but still very long, I have a goal of making this happen in a second if possible. This may help me find an even faster solution once I understand ...

Hello, I am trying to find an alternative to using " -channel A -morphology dilate octagon:61 " because it takes 1 minute 59 seconds to complete. I have tried using " bordercolor none -border 60x60 -background White -alpha background -channel A -blur 60x10 -level 0,0% -threshold 0 " but the shape ...

My Version: ImageMagick 6.9.1-10 Q16 x86_64 2015-07-26 Platform: Mac OSX El Capitan 10.11.6 Having trouble finding a way that would reposition layer 0 via -geometry -repage before placing it on underlay... How can I keep this as one command to position the edits made to artwork.png and resize and ...

Okay, here is what I did to achieve:

I should clarify. I want to keep the transparent area transparent from "artwork.png".

Thank you Fred. Much closer. The second output is closer to what I am looking to do "out2.png". I was able to achieve that with flatten : convert artwork.png -flatten alpha.png -gravity Center -alpha Off -compose copy_opacity -composite png:out.png I want to keep the white area transparent also ...

Placed platform in above also. Sorry.

Anyone have a suggestion for how I can alter the following command to crop one PNG with another PNG? convert artwork.png alpha.png -gravity Center -alpha Off -compose copy_opacity -composite out.png Currently the issue I am seeing is on my existing PNG image a black block appears where another PNG ...

It came down to the order of operations along with a few other things but in the end this command worked: convert \ \( xc:white[2000x2000\!] \) \ \( -clone 0 null: \( large.jpg -coalesce \) -gravity Center -layers Composite -layers Optimize \) \ \( -clone 0 null: \( medium.jpg -coalesce \) -gravity ...

@anthony Thank you very much for the references.

@sergpush Apologize for the delay in response, went away for the weekend. Thank you for your rapid response. I gave your suggestion a try and it resolved the alpha transparency issue I was having. The layers still aren't being processed correctly, but at least one problem solved.
