getNativeFormat

public int getNativeFormat()

Returns the native format of the screen, as a constant from the Pixels class.

Specified by:

getNativeFormat in interface NativeScreen

getWidth

public int getWidth()

Returns the pixel width of the screen.

Specified by:

getWidth in interface NativeScreen

getHeight

public int getHeight()

Returns the pixel height of the screen.

Specified by:

getHeight in interface NativeScreen

getDPI

public int getDPI()

Returns the number of pixels per inch in the screen.

Specified by:

getDPI in interface NativeScreen

getScale

public float getScale()

Description copied from interface: NativeScreen

getNativeHandle in interface NativeScreen

shutdown

public void shutdown()

Called during JavaFX shutdown to release the screen. Called only once.

Specified by:

shutdown in interface NativeScreen

uploadPixels

public void uploadPixels(java.nio.Buffer b,
                         int x,
                         int y,
                         int width,

Parameters:

b - Pixel data, in BYTE_BGRA_PRE format. The byte stride of the data is equal to width * 4.

x - The X offset of the pixel data on the screen

y - The Y offset of the pixel data on the screen

width - The pixel width of the data

height - The pixel height of the data

alpha - The alpha level to use to compose the data over existing pixels
