Method Details

convertChannels

public static ByteBuffer convertChannels(IntFunction<ByteBuffer> allocator,
 ByteBuffer src,
 int srcChannels,
 int width,
 int height,
 int desiredChannels,
 boolean is16Bit)

Converts interleaved pixel channels between 1/2/3/4-channel layouts.

Parameters:

allocator - destination allocator

src - source interleaved pixel buffer

srcChannels - source channel count

width - image width

height - image height

desiredChannels - target channel count

is16Bit - true for 16-bit channel elements

Returns:

converted buffer

verticalFlip

public static ByteBuffer verticalFlip(IntFunction<ByteBuffer> allocator,
 ByteBuffer src,
 int width,
 int height,
 int channels,
 boolean is16Bit)

Flips interleaved pixel data vertically.

Parameters:

allocator - destination allocator

src - source pixels

width - image width

height - image height

channels - channel count

is16Bit - true for 16-bit elements (2 bytes per channel)

Returns:

vertically flipped buffer

verticalFlip

public static ByteBuffer verticalFlip(IntFunction<ByteBuffer> allocator,
 ByteBuffer src,
 int width,
 int height,
 int channels,
 int bytesPerChannel)

Flips interleaved pixel data vertically using explicit channel byte width.

Parameters:

allocator - destination allocator

src - source pixels

width - image width

height - image height

channels - channel count

bytesPerChannel - bytes per channel element

Returns:

vertically flipped buffer
