Convert raw data to jpeg
I have found a way on how to convert raw data to jpeg but I have some issues with it. My app takes a picture on the current frame (onPreviewFrame) and has the raw data in a bytearray.
First of all, the code I found is only supported by android API 7+ (Android 2.1+). I want this app to be able to use since API 4+ so android 1.6 users can also enjoy the app. Second thing is that I have found some code to convert raw2jpg, but it is copyright protected so I can't use it.
I want to put it in a bytearray, so I won't use takePicture with it, remember.
Does anyone have an idea or some code snippet that I can use on how to convert raw data taken on a current frame to make a jpeg image in a bytearray from Android version 1.6?
EDIT: Here is the code:
private void raw2jpg(int[] rgb, byte[] raw, int width, int height)
{
final int frameSize = width * height;
for (int j = 0, yp = 0; j < height; j++)
{
int uvp = frameSize + (j >> 1) * width, u = 0, v = 0;
for (int i = 0; i < width; i++, yp++)
{
int y=0;
if( yp < raw.length)
{
y = (0xff & ((int) raw[yp])) - 16;
}
// int y = (0xff & ((int) raw[yp])) - 16;
if (y < 0) y = 0;
if ((i & 1) == 0)
{
if(uvp<raw.length)
{
v = (0xff & raw[uvp++]) - 128;
u = (0xff & raw[uvp++]) - 128;
}
}
int y1192 = 1192 * y;
int r = (y1192 + 1634 * v);
int g = (y1192 - 833 * 开发者_如何学Gov - 400 * u);
int b = (y1192 + 2066 * u);
if (r < 0) r = 0; else if (r > 262143) r = 262143;
if (g < 0) g = 0; else if (g > 262143) g = 262143;
if (b < 0) b = 0; else if (b > 262143) b = 262143;
rgb[yp] = 0xff000000 | ((r << 6) &
0xff0000) | ((g >> 2) &
0xff00) | ((b >> 10) &
0xff);
}
}
}
