@mperice Did it help, can I close this?

Of course, installing pngout solves the problem. My point was that pngout (as well as svgo) shouldn't be listed as (optional) packages anymore, as they are now apparently a necessity in v0.11.1.

«Optional» was meant about installation, but it is not a good word in this case as all workers are optional and image_optim will fail with an exception if you don't disable a worker with missing binary.
I am going to switch to resolving binaries for all workers by default on init instead of when worker is first used for more controlled environment. And I was going to add ability to warn and skip workers instead of failing if binary can not be found.

I had some surprise ActionView::Template::Error errors today because the railtie tried to load svgo, which up until now I had no idea existed.
What do I need to do to disable the svgo worker?

@vdh File config echo 'svgo: false' >> .image_optim.yml (or to global config file ~/.config/image_optim.yml) or rails config config.assets.image_optim = {:svgo => false}

So would that also work for the direct method?
image_optim = ImageOptim.new(pngout: false, svgo: false)At the moment I'm only using the direct ImageOptim within CarrierWave, so I've disabled the railtie with config.assets.image_optim = false for now.

Yes. If config.assets.image_optim is a Hash it will be passed directly to initialiser.

@mperice @vdh I've switched to resolving binaries during initialisation (on master, not yet released), with exception explaining how to disable workers. Dose this resolve this issue for you?

I'm having this same issue. Where do I install pngout? For some reason, image optim can't find it.

@jonathanng The easiest is to put it into any location in PATH. Note that value of PATH can be different in login shell and other environments, you can check its value in ruby app by logging ENV['PATH'].

It's in my path. I have it both in /usr/bin & /bin.
Does it need a certain naming convention? It's just called pngout. Do I
need the version number?

@jonathanng /usr/bin or /bin should normally work.
Bin should be named simply pngout.
Can you check that you've downloaded and you are using proper binary for your system/processor - do you get pngout help output if you run just pngout?

When I type pngout in console, i do get the pngout help output.
I'm on Mac, but I'm not sure if that should make a difference.

@jonathanng I can't yet understand if the problem is with environment, pngout binary or with image_optim.
Do you run image_optim binary or do you use it from ruby? If former, does image_optim binary work from terminal on png images? If later, does system('pngout') produce output from ruby?
Also please post first line of pngout help output containing its version.

When I type pngout in console, I get:
PNGOUT [In:{PNG,JPG,GIF,TGA,PCX,BMP}] (Out:PNG) (options...) Feb 21 2013
by Ken Silverman (http://advsys.net/ken)
Mac port assistance by Jonathon Fowler (http://www.jonof.id.au/pngout)
PNGOUT optimizes PNG size losslessly using my own deflate algorithm (not Zlib)
With the right options, it can often beat other programs by 5-10%. Options:
-c# PNG output color: 0=Gray, 2=RGB, 3=Pal, 4=Gray+Alpha, 6=RGB+Alpha
-f# PNG output filter: 0=none, 1=x, 2=y, 3=x&y, 4=Paeth, 5=mixed, 6=reuse
-d# Override default bitdepth: 0(min),1,2,4,8 (valid only in /c0,/c3 modes)
-s# Select strategy. 0:Xtreme(default), 1:Intense, 2:Longest Match,
3:Huffman Only, 4:Uncompressed
-b# Block split threshold (lower=more blocks, 0=1 block/file, default=256)
Use trial&error! Suggested values to try are: 0,128,192,256,512,1024,..
-n# Exact number of Huffman blocks (overrides /b#)
-r Randomized initial tables (good for many trials with same options)
-k? 0=Remove optional chunks (default), 1=Keep all
p=Keep palette indices, s=Keep settings for /c,f,d,b
-k(Chunk,Chunk,..) Preserve only named chunk(s). Example: -kgAMA,bKGD,tEXt
-v,q,l Verbose,Quiet,List mode (use '-' as filename to specify stdin/stdout)
-y Assume Yes at the 'overwrite file?' prompt
-force Write file even if bigger.
-mincodes# Workaround for buggy decoders. 1:Zlib 1.2.1 bug, 2:buggy mobiles
The 1st filename is the input. If you omit the output
filename, PNGOUT will use the same filename with a .PNG extension. Examples:
$ pngout inlarge.bmp outsmall.png <- writes outsmall.png
$ pngout duke3d.png -c2 -f3 -b128 -kbKGD -v <- writes duke3d.png if smaller

@jonathanng My previous message was confusing, please check if image_optim bin works from console on png images. If it does, than something is wrong in environment of rails app, check if system('pngout') produces same output from rails console with production environment.

image_optim does work in terminal.
When I type in the Rails console, I get the following:
>> system('pngout')
/usr/local/bin/pngout: /usr/local/bin/pngout: cannot execute binary file
I tried different versions of the image_optim gem and the latest one that isn't giving me problems is
gem 'image_optim', '~> 0.9.1'
Not sure if this helps or not.

commented on May 28, 2024
@jonathanng Now clearer: cannot execute binary file means that /usr/local/bin/pngout is not a binary for your os (probably you've downloaded one for different os).
I've already thought that it is better to detect "strange/invalid/unknown" binaries in image_optim resolving.
Somewhere in your rails app (or maybe in rvm) PATH variable is changed so that /usr/local/bin gets in front and invalid pngout binary is used.
Compare output of echo $PATH from terminal and puts ENV['PATH'] from rails console.
image_optim up to version 0.9.1 did not include railtie.

commented on May 28, 2024
@avinashdvv You either need to make pngout available in path or disable the worker in yml config or through options to image_optim initialiser. Which version are you using?
