Installing

Please read Modules instalation section before.

git clone https://github.com/ivanoff/images-manipulation-performance.git

cd images-manipulation-performance

npm install

Testing

npm test

Using

node index.js <source_folder> <result_folder>

where <source_folder> is foulder where original images are stored, <result_folder> is folder, where result images will be saved.

for example:

node index.js ../original ../result

Result example

Found images:

Found modules: canvas.js, gm-imagemagic.js, gm.js, lwip.js
== START ==
canvas.js : 4.001 img/sec; done in 7.498536 sec; minCPUidle: 96%; minFreeMem: 283Mb; MaxLoadAvg: 1.48
gm-imagemagic.js : 1.206 img/sec; done in 24.88003 sec; minCPUidle: 96%; minFreeMem: 456Mb; MaxLoadAvg: 1.59
gm.js : 1.536 img/sec; done in 19.528429 sec; minCPUidle: 96%; minFreeMem: 490Mb; MaxLoadAvg: 1.84
lwip.js : 0.406 img/sec; done in 73.891623 sec; minCPUidle: 96%; minFreeMem: 157Mb; MaxLoadAvg: 1.56
== DONE ==

In this example you can see, than canvas module is the best, regards to speed of processing of images (~4 imgages per second on my local computer)
