Method Detail

getReversed

public static PixelFormat getReversed(PixelFormat fmt)

Returns the PixelFormat with reversed components of fmt. If no reversed PixelFormat is available, returns fmt.

getValue32

public static int getValue32(PixelFormat src_fmt,
                             ByteBuffer src,
                             int srcOff)

convertToInt32

public static int convertToInt32(PixelFormat dest_fmt,
                                 byte r,
                                 byte g,
                                 byte b,

convertToInt32

public static int convertToInt32(PixelFormat dest_fmt,
                                 PixelFormat src_fmt,
                                 ByteBuffer src,

                                 int src_pixel)

convert32

public static PixelRectangle convert32(PixelRectangle src,
                                       PixelFormat destFmt,
                                       int ddestStride,

                                       boolean destIsDirect)

convert32

public static void convert32(PixelFormatUtil.PixelSink32 destInt32,
                             PixelRectangle src)

convert32

public static void convert32(PixelFormatUtil.PixelSink32 dest32,
                             ByteBuffer src_bb,
                             PixelFormat src_fmt,
                             boolean src_glOriented,
                             int width,
                             int height,
                             int stride_bytes)

Parameters:

dest32 - 32bit pixel sink

src_bb -

src_fmt -

src_glOriented - if true, the source memory is laid out in OpenGL's coordinate system, origin at bottom left, otherwise origin at top left.

width -

height -

strideInBytes - stride in byte-size, i.e. byte count from one line to the next. If zero, stride is set to width * bytes-per-pixel. If not zero, value must be >= width * bytes-per-pixel.

stride_bytes - stride in byte-size, i.e. byte count from one line to the next. Must be >= src_fmt.bytesPerPixel() * width.

Throws:

IllegalArgumentException - if strideInBytes is invalid
