Method Detail

writeBytes8

public static byte[] writeBytes8(Pix pixs)

Write an 8bpp Pix to a flat byte array.

Parameters:

pixs - The 8bpp source image.

Returns:

a byte array where each byte represents a single 8-bit pixel

writeBytes8

public static int writeBytes8(Pix pixs,
                              byte[] data)

Write an 8bpp Pix to a flat byte array.

Parameters:

pixs - The 8bpp source image.

data - A byte array large enough to hold the pixels of pixs.

Returns:

the number of bytes written to data

writeImpliedFormat

public static boolean writeImpliedFormat(Pix pixs,
                                         File file)

Writes a Pix to file using the file extension as the output format; supported formats are .bmp, .jpg, and .png.

Notes:

1. This determines the output format from the filename extension.

Parameters:

pixs - Source image.

file - The file to write.

Returns:

true on success

writeBitmap

public static Bitmap writeBitmap(Pix pixs)

Writes a Pix to an Android Bitmap object. The output Bitmap will always be in ARGB_8888 format, but the input Pixs may be any bit-depth.

Parameters:

pixs - The source image.

Returns:

a Bitmap containing a copy of the source image, or null on failure
