java.lang.Objectjarp.ImageBytes
public class ImageBytes
Basic data for a rectangular array of (RGBA) pixel data held as a
byte-array, wrapped in a direct java.nio.ByteBuffer
; the pixel
array dimensions are W x H (x 4 bytes-per-pixel), with the origin
at the BOTTOM-LEFT, as required by OpenGL.
Field Summary | |
---|---|
int |
H
Image height in pixels |
java.nio.ByteBuffer |
IMG_BYTE_BUFFER
Image bytes buffer: W x H groups of 4
(0123-->RGBA, the little-endian integer ABGR). |
int |
W
Image width in pixels |
Constructor Summary | |
---|---|
ImageBytes(java.awt.image.BufferedImage bimg)
Constructor, taking data from a BufferedImage. |
|
ImageBytes(java.awt.image.BufferedImage bimg,
boolean israwRGBA,
boolean vflippedbimg)
Constructor taking its data from a BufferedImage, whose pixel data may be in raw (RGBA) form or in BGRA form (Java TYPE_INT_ARGB) as indicated by israwRGBA , and which may
already be vertically flipped as indicated by vflippedbimg . |
|
ImageBytes(int w,
int h,
byte[] imgbytes)
Basic constructor, taking image data from an array. |
|
ImageBytes(JAInputStream jins,
boolean COMPRESSED,
boolean IS_V22)
Image-bytes constructor that takes the image data directly from the specified stream; this data may or may not be compressed, as indicated by COMPRESSED ,
and may be in v2.1 or v2.1 avatar definition format, as specified
by IS_V22 . |
Method Summary | |
---|---|
void |
save(JAOutputStream jouts,
boolean compress)
Saves this image on the given JA output-stream (in v2.2 avatar definition format), compressed or uncompressed as specified. |
void |
saveAsPNG(JAOutputStream jouts,
boolean vflippng)
Saves this image in PNG format on the specified output stream, vertically flipped if vflippng is true. |
void |
saveAsPNG(java.lang.String outfile,
boolean vflippng)
Saves this image in PNG format on the specified file, vertically flipped if vflippng is true. |
void |
writeToStream(JAOutputStream jouts,
boolean pfxbcount)
Writes this image's data on the given output stream, with or without an image byte-count prefix, as specified. |

public ImageBytes(JAInputStream jins, boolean COMPRESSED, boolean IS_V22) throws java.io.IOException
COMPRESSED
,
and may be in v2.1 or v2.1 avatar definition format, as specified
by IS_V22
.
In both v2.1 and v2.2 format the image data itself consists of
two integers, giving the image
width, W
, and height, H
, in pixels,
followed by N = W * H * 4
image bytes themselves
(4 bytes per pixel, in the order RGBA).
In the input stream the data may or may not be
compressed, as determined by the relevant flag byte.
N
, the number of image bytes, followed by the image data
as described above.2 * 4 + N
), followed by the image data itself.
