Functions
static thread_local std::mt19937	geometrize::commonutil::mt (std::random_device{}())
void	geometrize::commonutil::seedRandomGenerator (std::uint32_t seed)
	seedRandomGenerator Seeds the (thread-local) random number generators. More...
std::int32_t	geometrize::commonutil::randomRange (std::int32_t min, std::int32_t max)
	randomRange Returns a random integer in the range, inclusive. Uses thread-local random number generators under the hood. To ensure deterministic shape generation that can be repeated for different seeds, this should be used for shape mutation, but nothing else. More...
geometrize::rgba	geometrize::commonutil::getAverageImageColor (const geometrize::Bitmap &image)
	getAverageImageColor Computes the average RGB color of the pixels in the bitmap. More...
bool	geometrize::commonutil::scanlinesContainTransparentPixels (const std::vector< geometrize::Scanline > &scanlines, const geometrize::Bitmap &image, int minAlpha)
	scanlinesContainTransparentPixels Returns true if the scanlines contain transparent pixels in the given image More...
std::tuple< std::int32_t, std::int32_t, std::int32_t, std::int32_t >	geometrize::commonutil::mapShapeBoundsToImage (const geometrize::ImageRunnerShapeBoundsOptions &options, const geometrize::Bitmap &image)
	mapShapeBoundsToImage Maps the given shape bound percentages to the given image, returning a bounding rectangle, or the whole image if the bounds were invalid More...
