| # path_ops |
| |
| A small library that exposes C bindings for Skia's SkPathOps, with a minimal |
| interface for SkPath. |
| |
| This library only supports four commands from SkPath: `moveTo`, `lineTo`, |
| `cubicTo`, and `close`. |
| |
| This library is a subset of the functionality provided by Skia's `PathKit` |
| library. It is primarily intended for use with the `vector_graphics` optimizing |
| compiler. That library uses this one to optimize certain masking and clipping |
| operations at compile time. |
| |
| ## Testing |
| |
| The `path_ops` library uses dynamic libraries (i.e. `libpath_ops.dylib` or the |
| equivalent on your platform) to link against the C++ code in |
| [`path_ops.cpp`](path_ops.cpp). When run through |
| [`run_tests.py`](../../testing/run_tests.py), paths are set automatically to |
| make finding the dynamic library work. |
| |
| However, if run directly from the command line or IDE, an environment variable |
| `DYLD_LIBRARY_PATH` (or equivalent on your platform) must be set to the |
| directory containing the dynamic library. For example, on macOS: |
| |
| ```sh |
| export DYLD_LIBRARY_PATH=BUILD_DIR |
| ``` |
| |
| ... where `BUILD_DIR` is the output directory for the engine build, such as |
| `../out/host_debug_unopt_arm64`. |
