Weekend coding: streaming image manipulations with Node.js

The author shares their experience of building a Node.js server that formats an image for display on a Pebble smartwatch. They discuss the challenges of optimizing images for low bandwidth devices and how they used Node.js streams to manipulate images without writing intermediate files to disk. They also explain how to use GraphicsMagick for Node.js to perform various image manipulations, such as cropping, resizing, adjusting contrast, mapping colors, dithering, and outputting the final image in PNG format. The author encourages readers to explore other features of GraphicsMagick and create their own creative applications using this technology.
