artfactory gem in Action - Generate Pixel Art Via Text-To-Image Prompts
Hello, In the ongoing learn pixel art programming with ruby series I put together a new artfactory gem that let’s you generate pixel art via text-to-image prompts - no A.I. training or models needed / required ;-). The “magic” works via all-in-one image spritesheets (and meta datasets in .csv). To get you started I “right-clicked & saved” about a dozen “on-blockchain” artwork layers for easy “off-blockchain” (re)use. Happy pixel pushing and profile pict(ure) pixel art generation with ruby.

25 Days of Punk (Pixel) Head / Character Art Collections - December 1st to 25th
Hello, Some years ago I used to organize and publish “25 Days of Ruby Gems - Ruby Advent Calendar 2020, December 1st - December 25th” and such (ironically I am cancel-cultured and perma-banned twice in the ruby world, that is, on r/ruby and ruby-talk (- see the (Ruby) Case Studies @ Choose A Conduct for the backstory). Anyways, let’s (re)try and revive the tradition with a punk (pixel) art twist (or is that pivot?). The idea is to publish a (free ruby pixel art programming how-to) article a day starting December 1st, 2022 that shows how you can put together (yes, you can!) do-it-yourself (DIY) a punk (pixel) art collection (from scratch). Yes, in ruby. You are more than welcome to “claim” a day and sign-up for an article in the series. .

[ANN] Perfect Shape 1.0.6 Released
PerfectShape is a collection of pure Ruby geometric algorithms that are mostly useful for GUI (Graphical User Interface) manipulation like checking viewport rectangle intersection or containment of a mouse click point in popular geometry shapes such as rectangle, square, arc (open, chord, and pie), ellipse, circle, polygon, and paths containing lines, quadratic bézier curves, and cubic bezier curves, potentially with affine transforms applied like translation, scale, rotation, shear/skew, and inversion (including both the Ray Casting Algorithm, aka Even-odd Rule, and the Winding Number Algorithm, aka Nonzero Rule). Additionally, PerfectShape::Math contains some purely mathematical algorithms, like IEEE 754-1985 Remainder. https://github.com/AndyObtiva/perfect-shape
