Constructor Details

NanoContext

public NanoContext()

Initializes a NanoVG context and returns this object.

Method Details

beginFrame

public void beginFrame(int windowWidth,
 int windowHeight)

Begins a new frame for rendering using NanoVG. This method calculates the pixel ratio based on the given window dimensions.

Parameters:

windowWidth - the width of the window in pixels

windowHeight - the height of the window in pixels

beginFrame

public void beginFrame(int windowWidth,
 int windowHeight,
 float pxRatio)

Begins a new frame for rendering using NanoVG with a specified pixel ratio. This method should be called at the start of each frame before any drawing operations.

Parameters:

windowWidth - the width of the window in pixels

windowHeight - the height of the window in pixels

pxRatio - the pixel ratio, which is typically the ratio of the framebuffer size to the window size

endFrame

public void endFrame()

Ends the current frame of rendering (nvgEndFrame(context))

isModernOpenGL

public boolean isModernOpenGL()

Returns:

true if the machine this program is running on supports modern OpenGL (Version 3 and above)

get

public long get()

Returns:

the NanoVG context long ID.

dispose

public void dispose()

Disposes this NanoVG context.
