Method Summary

void	compress(int inSize, byte[] pInBuff, int[] pOutSize, byte[] pOutBuff) Compress the current the input buffer.
void	compressByLevel(int inSize, byte[] pInBuff, int level, int[] pOutSize, byte[] pOutBuff) Compress the current the input buffer by level.
int	getBufferSize(int size) Estimated buffer size of compress/uncompress texture data.
void	unCompress(int inSize, byte[] pInBuff, int[] pOutSize, byte[] pOutBuff) UnCompress the current the input buffer.

Method Detail

getBufferSize

int getBufferSize(int size)
                  throws IOException,

Parameters:

size - The size (in)

Returns:

The pSize

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

compress

void compress(int inSize,
              byte[] pInBuff,
              int[] pOutSize,
              byte[] pOutBuff)
              throws IOException,
                     AutomationException

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Parameters:

inSize - The inSize (in)

pInBuff - An unsigned byte (in)

pOutSize - The pOutSize (in/out: use single element array)

pOutBuff - An unsigned byte (in/out: use single element array)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

compressByLevel

void compressByLevel(int inSize,
                     byte[] pInBuff,
                     int level,
                     int[] pOutSize,
