# Boost.GIL Examples
This directory contains
- examples of C++ programs using GIL
- configuration files for CMake integrations in popular IDEs
We provide Boost.Build (`Jamfile`) and CMake (`CMakeLists.txt`)
configurations to build the examples.
See the [CONTRIBUTING.md](../CONTRIBUTING.md)
for details on how to run `b2` and `cmake` for Boost.GIL.
Each example is build as a separate executable.
Each executable generates its output as `out-<example_name>.jpg`.
For example, the `resize.cpp` example generates the image `out-resize.jpg`.
The following examples are included:
1. `resize.cpp`
Scales an image using bilinear or nearest-neighbour resampling.
2. `affine.cpp`
Performs an arbitrary affine transformation on the image.
3. `convolution.cpp`
Convolves the image with a Gaussian kernel.
4. `mandelbrot.cpp`
Creates a synthetic image defining the Mandelbrot set.
5. `interleaved_ptr.cpp`
Illustrates how to create a custom pixel reference and iterator.
Creates a GIL image view over user-supplied data without the need to cast to GIL pixel type.
6. `x_gradient.cpp`
Horizontal gradient, from the tutorial
7. `histogram.cpp`
Algorithm to compute the histogram of an image
8. `packed_pixel.cpp`
Illustrates how to create a custom pixel model - a pixel whose channel size is not divisible by bytes.
9. `dynamic_image.cpp`
Example of using images whose type is instantiated at run time.
