virtual bool load(Vector2u size, std::unique_ptr< std::uint8_t[]> pixels)
Loads the texture from an array of 32-bits RGBA pixels.
virtual bool isSmooth() const =0
Returns whether the smooth filter is enabled or not.
bool isTransparentPixel(Vector2u pixel) const
Checks if a certain pixel is transparent.
virtual Vector2u getSize() const =0
Returns the size of the entire image.
virtual ~BackendTextureBase()=default
Virtual destructor.
virtual void setSmooth(bool smooth)=0
Changes whether the smooth filter is enabled or not.
Namespace that contains all TGUI functions and classes.
