Method Details

compress

int compress(int comp,
 byte[] src,
 int srcOffset,
 int numBytes,

Compress numBytes bytes of image data from src, storing in dest (starting at 0), using the technique specified by comp. If last is true, this indicates the last line of the image. Answer the size of the compressed data.

compressRLE4Data

int compressRLE4Data(byte[] src,
 int srcOffset,
 int numBytes,
 byte[] dest,
 boolean last)

compressRLE8Data

int compressRLE8Data(byte[] src,
 int srcOffset,
 int numBytes,
 byte[] dest,
 boolean last)

convertPixelsToBGR

void convertPixelsToBGR(ImageData image,
 byte[] dest)

decompressData

void decompressData(byte[] src,
 byte[] dest,
 int stride,
 int cmp)

decompressRLE4Data

int decompressRLE4Data(byte[] src,
 int numBytes,
 int stride,
 byte[] dest,
 int destSize)

decompressRLE8Data

int decompressRLE8Data(byte[] src,
 int numBytes,
 int stride,
 byte[] dest,
 int destSize)
