Sorry, that's not it. spidersoft.com.au is not reachable.

Sorry, did you take the pain to check?

There are some issues with this domain name - I'm working on fix. It's visible from some locations - but not for everyone.

from codeigniter-img.

Problems with the domain are solved. DBAA about it...

What do you mean with DBAA, please?

D:> ping www.spidersoft.com.au
Ping request could not find host "www.spidersoft.com.au". Check the name and try again.

Maybe this will be fixed in a couple of hours...

from codeigniter-img.

Ok now, issue resolved.

For the record:

Well, on my Windows box it was not. But curl -v "https://www.spidersoft.com.au" worked fine on my CentOS box. So it must be an issue of DNS nameserver.

I reconfigured Windows from automatic to 8.8.8.8 / 8.8.4.4 (Google public nameserver), to no avail. So I suspected that I had to reboot, which I should not have to.

I had a lookup of the DNS nameserver on CentOS with cat /etc/resolv.conf and reconfigured Windows accordingly, again no result. (I probably did not close the dialog, so the changed data was not set.)

Next I followed the advice of my browser Opera to configure Opera to use a different nameserver. I chose the preconfigured Google option and had success.

Next I configured Windows DNS nameserver with all the different variants and all of them worked, except the default which is my Internet-provider. (I probably closed the dialog, so the changed data was set.) Well, this, too, may change. And lo, it did.

Redirect

Well, not yet. Trying http://www.spidersoft.com.au/projects/codeigniter-img-thumbnails-on-the-fly/ in Opera via Google resulted in the known error. Why? Ok, no automatic redirect to https, which is state of the art, as far as I know.

curl works fine, though. Why? Maybe because of

< X-Pingback: http://www.spidersoft.com.au/xmlrpc.php
< Link: <https://www.spidersoft.com.au/wp-json/>; rel="https://api.w.org/", <https://www.spidersoft.com.au/wp-json/wp/v2/pages/327>; rel="alternate"; type="application/json", <https://www.spidersoft.com.au/?p=327>; rel=shortlink

curl seems to know about pingbacks, I don't and I don't want to learn about it, so I leave it at that.

https://www.spidersoft.com.au/projects/codeigniter-img-thumbnails-on-the-fly/ reveals no new information but instead refers back to github-documentation, so all this effort was in vain, it seems.

Speed

By the way, my testing revealed that resizing with GraphicsMagic is roughly 10 times faster than gd.

        $cmd = "gm convert  -size $size^ $file -filter Lanczos -resize $size^ -crop $size -unsharp 2x0.5+1.0+0 -quality 70 $file_new2";
        $res = exec($cmd);

Résumé

So, in the end, this library will not be used. Learned something, though, so I don't regret the endeavor.

from codeigniter-img.

Every external library will be faster than PHP, if you are looking for real speed try https://github.com/libvips/libvips

Interesting, thank you!

I made me a vips-container via https://github.com/codechimp-io/vips-alpine/blob/master/Dockerfile and tested with a jpg-file 1000px wide against GraphicsMagick:

1. pick containter having GraphicsMagick

id=$(docker ps -a | grep "vx_wsm.1\." | grep -v "xited" | awk '{print $1}') && docker exec -it $id ash

in container run test

/ # time gm convert  -size 287x137^ /tmp/img/_voxx_AdMark.jpg -filter Lanczos -resize 287x137^ -crop 287x137 -unsharp 2x0.5+1.0+0 -quality 90 /tmp/img/287/_voxx_AdMark.jpg
real    0m 0.04s
user    0m 0.01s
sys     0m 0.00s

2. start vips container

docker run -it --rm -v /tmp:/tmp --name u1 kklepper/vips:alpine sh

in container run test

/ # time vipsthumbnail /tmp/img/_voxx_AdMark.jpg --size 287x137 -o /tmp/img/287/%s.jpg[Q=90,optimize_coding]
real    0m 0.43s
user    0m 0.04s
sys     0m 0.02s

Result: gm beats vips by 10x

I think vips has a lot of overhead -- no wonder, because after all -- if I understood correctly -- vips just uses ImageMagick as a submodule.

Not sure how did you run your benchmarks but: https://github.com/libvips/libvips/wiki/Speed-and-memory-use

from codeigniter-img.

Thank you, interesting.

Not sure how did you run your benchmarks

Well, I gave you the recipe, didn't I? My GM container is a standard PHP container with GM as addon, so nothing special.

from codeigniter-img.

I'm just wondering why there is a such a difference between your benchmarks and theirs. You claim that 10x faster, they are saying it's 4x slower :)

from codeigniter-img.

Good question. I don't know. You should be able to reproduce. I'd rather go back to work than care any longer, at least for now.
