Access to imgscalr options

[vvvvalvalval]

I've been using imagez to scale down JPEG images but I was dissatisfied with the output quality.

Turns out that you can improve it significantly by using the ULTRA_QUALITY method of imgscalr.

would be interesting to make those options accessible.

Sounds like a good idea. Perhaps ULTRA_QUALITY should even be the default?

[vvvvalvalval]

@mikera I agree, I cannot see any reason not to use it by default (except performance requirements).

[vvvvalvalval]

@mikera On second thought, having dived a little bit in the documentation, I believe the best course of action is to leave AUTOMATIC by default (which by definition is meant to let the library try and be smart about the algorithm to be used), while exposing tuning options to the user and providing her a link to the documentation.

Hi. I am facing the same issue. I can't get a good quality output after scaling (resizing) down an image. @vvvvalvalval, how did you solve the problem?

[vvvvalvalval]

@rcanepa I ended up going down to ImgScalr via Java interop. Shoud be fairly easy for you to do by looking at the source code of imagez.

[rcanepa]

@vvvvalvalval, excellent. I'll do that too.

Happy to have a PR that exposes the options to Clojure (as an additional options map)

@mikera just started using this library - it's fantastic. I have a need for this too, are you still open to PRs?

[mikera]

Glad you like it! PRs very welcome!
