Image Processing in Ruby with GD: Exploring ruby-libgd v0.3.0

Image Processing in Ruby with GD: Exploring ruby-libgd v0.3.0 March 4, 2026 Image processing is usually associated with languages like Python or C++, but Ruby can also manipulate images efficiently thanks to bindings for native libraries. One of those libraries is libgd, a well-known C library used to dynamically generate and manipulate images such as … Continue reading Image Processing in Ruby with GD: Exploring ruby-libgd v0.3.0

Understanding Convolution Filters in Image Processing (and Adding Them to Ruby-LibGD v0.2.5)

Understanding Convolution Filters in Image Processing (and Adding Them to Ruby-LibGD v0.2.5) March 3, 2026 Today I implemented support for custom convolution filters in Ruby-LibGD, enabling the application of kernels such as blur, sharpen, and edge detection directly from Ruby. At first glance, this may look like just another image filter. In reality, convolution is … Continue reading Understanding Convolution Filters in Image Processing (and Adding Them to Ruby-LibGD v0.2.5)
