Command failed with exit code when using ImageAlpha (works great without it)

[rc042]

Hi!

I meet an issue and I don't know how to solve it...

Steps To Reproduce The Error

Try to process a file or multiple file, for example:

$ imageoptim -a EXP_IMG_893010262019.png

$ imageoptim -a '**/*.png'

Expected Behaviour

Actual Behaviour

I've got an error (see below).

Output error looks like:

$ imageoptim -a EXP_IMG_893010262019.png
i Running ImageAlpha...
! Command failed with exit code 98 (Unknown system error -98): /Applications/ImageAlpha.app/Contents/MacOS/pngquant --ext=.png --force --skip-if-larger --speed=1 --quality=65-80 256 -- /var/folders/k6/78rvflqd1fd8zyttzqy7zkqm0000gn/T/imageoptim-cli/EXP_IMG_893010262019.png

Version Numbers or N/A

• macOS: 10.14.6
• /Applications/ImageOptim.app: 3.0.0
• /Applications/ImageAlpha.app: 1.5.1
• /Applications/JPEGmini.app: N/A (not used)

Help Needed

I tried to execute pngquant and it eems to work without problem:

$ /Applications/ImageAlpha.app/Contents/MacOS/pngquant --ext=.png --force --skip-if-larger --speed=1 --quality=65-80 256 -- /var/folders/k6/78rvflqd1fd8zyttzqy7zkqm0000gn/T/imageoptim-cli/EXP_IMG_893010262019.png

Other thing, it works fine without option:

$ imageoptim '**/*.png'
i Running ImageOptim...

Thanks!

As far as I can tell from this search: error code 98 refers to an image which is too large for pngquant to handle, but it looks like EXP_IMG_893010262019.png was 2.99MB in size which I don't expect to be a problem.

I will be honest with you, I'm unable to reproduce this and don't have ideas for a fix at the moment.

The code 98 is a normal behavior. It's returned when --skip-if-larger worked as advertised.

Thanks @kornelski. I am unblocked and can take a look at how this CLI is handling error codes.

Fix released in 3.0.2

Hi, a little word to say thank you! It works fine with this version :)
