Java BufferedImage Operation intBuffer2BufferedImage(IntBuffer ib, BufferedImage img)

Description

Convert IntBuffer to BufferedImage.

License

Open Source License

Parameter

Parameter	Description
ib	each 4-byte (ARGB) integer in IntBuffer corresponds to a pixel in the BufferedImage ib should have width*height of integers. ib is little endian so the byte order is BGRA. ib is a direct buffer which has no backup array, so ib.array() will fail.
bi	BufferedImage should have type TYPE_INT_ARGB

Declaration

public static void intBuffer2BufferedImage(IntBuffer ib, BufferedImage img)
