ImageFlags
Flags that affect the tileability or interpolation of an image.
The library&#39;s main namespace.
Definition: Audio.hpp:12
Transform scale(double factor)
Apply nearest-neighbor interpolation when scaling this image up or down.
std::array< double, 16 > Transform
Transform concat(const Transform &lhs, const Transform &rhs)
double ZPos
Represents the Z position of something drawn with Gosu&#39;s graphics system.
Transform rotate(double angle, double around_x=0, double around_y=0)
double angle(double from_x, double from_y, double to_x, double to_y, double def=0)
Returns the angle from point 1 to point 2 in degrees, where 0.0 means upwards.
The color&#39;s channels will be interpolated.
Transform translate(double x, double y)
Macros and utility functions to facilitate programming on all of Gosu&#39;s supported platforms...
AlphaMode
Determines the way colors are combined when one is drawn onto another.
The color&#39;s channels will be multiplied with each other.
The colors&#39; channels will be added.
