Implementations
impl OpenGl
[src]
pub fn new<F>(load_fn: F) -> Result<Self, ErrorKind> where
F: FnMut(&str) -> *const c_void,
[src]
F: FnMut(&str) -> *const c_void,
pub fn is_opengles(&self) -> bool

pub fn set_screen_target(
&mut self,
framebuffer_object: Option<<Context as HasContext>::Framebuffer>
)
[src]
&mut self,
framebuffer_object: Option<<Context as HasContext>::Framebuffer>
)
Make the "Screen" RenderTarget actually render to a framebuffer object. This is useful when
embedding femtovg into another program where final composition is handled by an external task.
The given framebuffer_object
must refer to a Framebuffer Object created on the current OpenGL
Context, and must have a depth & stencil attachment.
Pass None
to clear any previous Framebuffer Object ID that was passed and target rendering to
the default target (normally the window).
