Mine images from PSD files

The application parses images from canvases/mobile.psd and canvases/tablet.psd files.

canvases/mobile.example.psd and canvases/tablet.example.psd files are used as examples. Create your own PSDs based on them. If you get any unexpected results just compare your and example PSDs.

The script generates images/mobile-file-list.txt and images/tablet-file-list.txt files with lists of paths to generated files.

For instance,

----------------------
images/2/tablet/IMG_8151|serform
images/2/tablet/IMG_8150|sequence
images/2/tablet/IMG_8148|sample
----------------------
images/3/tablet/IMG_8153|copy

Mine your PSD!

Images add into the images/ folder.

python mine-psd.py

Installation ruby via rvm generates the next error.

Error running '__rvm_make -j16',
please read /home/stas/.rvm/log/1692449785_ruby-3.0.0/make.log

There has been an error while running make. Halting the installation.

Point OpenSSL during installation

Running bundle raises an OpenSSL error.

Could not load OpenSSL.
You must recompile Ruby with OpenSSL support or change the sources in your Gemfile from 'https' to 'http'. Instructions for compiling with OpenSSL
using RVM are available at rvm.io/packages/openssl.

Reinstall Ruby pointing OpenSSL during the installation

rvm reinstall 3.1.4 --with-openssl-dir=/usr/bin/openssl

Reinstall Ruby with disabled "autolibs"

rvm install 3.14 --autolibs=disable
