NVG_ANTIALIAS
public static final int NVG_ANTIALIAS
Flag indicating if geometry based anti-aliasing is used (may not be needed when using MSAA).- See Also:
- Constant Field Values
-
NVG_STENCIL_STROKES
public static final int NVG_STENCIL_STROKES
Flag indicating if strokes should be drawn using stencil buffer. The rendering will be a little slower, but path overlaps (i.e. self-intersecting or sharp turns) will be drawn just once.- See Also:
- Constant Field Values
-
NVG_DEBUG
public static final int NVG_DEBUG
Flag indicating that additional debug checks are done.- See Also:
- Constant Field Values
-
NVG_IMAGE_NODELETE
public static final int NVG_IMAGE_NODELETE
Do not delete GL texture handle.- See Also:

nvglCreateImageFromHandleGL3
public static int nvglCreateImageFromHandleGL3(long ctx, int textureId, int w, int h, int flags)
Creates a NanoVG image from an OpenGL texture.- Parameters:
ctx
- the NanoVG contexttextureId
- the OpenGL texture idw
- the image widthh
- the image heightflags
- the image flags
-
nvglImageHandleGL3
public static int nvglImageHandleGL3(long ctx, int image)
Returns the OpenGL texture id associated with a NanoVG image.- Parameters:
ctx
- the NanoVG contextimage
- the image handle
-
nvgCreateGL3
public static long nvgCreateGL3(int flags)
Creates a NanoVG context with an OpenGL 3.0 rendering back-end.An OpenGL 3.0+ context must be current in the current thread when this function is called and the returned NanoVG context may only be used in the thread in which that OpenGL context is current.
- Parameters:
flags
- the context flags. One of:ANTIALIAS
STENCIL_STROKES
