Some formats don't seem to work

[grenmester]

I tried querying pngs and jpgs and it seems to be returning nothing.

The following svg works fine: http://cube.crider.co.uk/visualcube.php?fmt=svg&size=150&pzl=2&alg=R2F2R2.

But when I try querying a png it gives me a blank page: http://cube.crider.co.uk/visualcube.php?fmt=png&size=150&pzl=2&alg=R2F2R2.

Have you installed ImageMagick?
try apt-get install ImageMagick -y

I think @grenmester says that other formats don't work on @Cride5's server.
E.g. command

$ curl 'http://cube.crider.co.uk/visualcube.php?fmt=svg&size=150&pzl=2&alg=R2F2R2'

returns an SVG code, but

$ curl 'http://cube.crider.co.uk/visualcube.php?fmt=png&size=150&pzl=2&alg=R2F2R2'

(note different fmt parameter) returns nothing.

So installing ImageMagick will not help him.

This bug is not only about formats but also about sizes. When I paste into browser this link:
http://cube.crider.co.uk/visualcube.php?fmt=png&size=201&pzl=2&alg=R2F2R2
it returns PNG file but this doesn't:
http://cube.crider.co.uk/visualcube.php?fmt=png&size=200&pzl=2&alg=R2F2R2
(note different size parameter).

Moreover for SVG both works properly:
http://cube.crider.co.uk/visualcube.php?fmt=svg&size=201&pzl=2&alg=R2F2R2
http://cube.crider.co.uk/visualcube.php?fmt=svg&size=200&pzl=2&alg=R2F2R2

@matbur
The reason is that server "cube.crider.co.uk" hasn't installed ImageMagick.
Installing ImageMagick on your own computer makes no effect.

You can try composing this project with docker on your own server.
I have built a docker image on my docker hub. lz1998/visualcube
docker run -d -p 80:80 lz1998/visualcube

Dockerfile
FROM php:7.2-apache
RUN apt-get update \
&& apt-get install imagemagick -y
COPY visualcube/ /var/www/html/
EXPOSE 80

@lz1998 you got a good idea. I created a PR with your Dockerfile. Thanks :)

The site has moved to a new domain is why.
