public abstract class WritablePixelFormat<T extends java.nio.Buffer> extends PixelFormat<T>
PixelFormat
object representing a pixel format that can store
full colors and so can be used as a destination format to write pixel
data from an arbitrary image.PixelFormat.Type

would return the pixel information for the
pixel at coordinates (0, 0)
.
The scanlineStride
parameter defines the distance from the pixel
data at the start of one row to the pixel data at the start of the
immediately following row at the next higher Y coordinate. Usually,
scanlineStride
is the same as the width of the image multiplied
by the number of data elements per pixel (1 for the case of the
integer and indexed formats, or 3 or 4 in the case of the byte
formats), but some images may have further padding between rows for
alignment or other purposes.buf
- the buffer of pixel datax
- the X coordinate of the pixel to be ready
- the Y coordinate of the pixel to be readscanlineStride
- the number of buffer elements between the
start of adjacent pixel rows in the bufferargb
- a 32-bit value with the color to be stored in the pixel
in a format similar to the Type.INT_ARGB
