processone/eimp

This system is an Erlang-based image processing library that handles identification, conversion, and scaling of images in formats including PNG, JPEG, WebP, and GIF. It features dynamic loading of external C libraries for format support and includes a configurable rate-limiting mechanism to control request throughput. The build infrastructure has been modernized to rebar3 with optional C library dependencies, ensuring robust compilation and testing across different environments.

The library now supports GIF format conversion and identification, expanding the range of supported image types beyond PNG, JPEG, and WebP. A new rate-limiting mechanism has been introduced via the eimp\_limit module, allowing users to configure request limits using limit\_by and rate\_limit options in convert and identify calls; exceeding these limits returns a too\_many\_requests error. The supervisor now starts the rate limiter alongside worker processes, and the application dependency list includes p1\_utils to support time compatibility functions used in the new limit logic.

The project has updated its build infrastructure to support rebar3, including a new Makefile that detects the rebar version and adjusts test and dialyzer commands accordingly. The configure script and build scripts have been refactored to make external C libraries (libgd, libjpeg, libpng, libwebp) optional; instead of failing the build if these headers or libraries are missing, the system now emits warnings and compiles with conditional macros (HAVE\_GD, HAVE\_JPEG, etc.) to disable support for unavailable formats at runtime. Additionally, the dependency on p1\_utils has been updated to version 1.0.29, and CI coverage reporting has been switched from Travis to GitHub Actions with Coveralls integration.

The image processing engine now loads external libraries (JPEG, PNG, WebP) dynamically at runtime instead of linking them statically, improving compatibility with systems where these libraries are not built with specific features like WebP. Additionally, GIF format support has been added, allowing the system to identify and process GIF images alongside existing PNG, JPEG, and WebP formats.

The test suite for the \eimp\ module has been expanded to cover new capabilities and edge cases. Tests now verify support for the GIF format (including conversion to and from PNG, JPEG, and WebP, as well as malformed GIF handling) and the new \identify/1\ function for retrieving image metadata. Additionally, the suite includes tests for the \scale\ transformation, a rate-limiting feature (verifying \too\_many\_requests\ errors), and an encode failure scenario for unsupported GIF-to-WebP conversions. Error handling tests have also been updated to include \image\_too\_big\ and \transform\_failure\ cases.
