Method Detail

createBufferParams

BufferParam createBufferParams(int w,
                               int h,
                               int bandCount,
                               int dataType,
                               boolean malloc)

Creates a parameter object for building a buffer. The buffer type is read-write. This type could be changed after the creation of a BufferParam object. The buffer will be cached if it's necessary

Parameters:

w - Width

h - Height

bandCount - Number of bands

dataType - Type of data

createMemoryBufferParams

BufferParam createMemoryBufferParams(int w,
                                     int h,
                                     int bandCount,
                                     int dataType,
                                     boolean malloc)

Creates a parameter object for building a buffer. The buffer type is read-write. This type could be changed after the creation of a BufferParam object. The buffer will be stored in memory.

Parameters:

w - Width

h - Height

bandCount - Number of bands

dataType - Type of data

createReadOnlyBufferParams

BufferParam createReadOnlyBufferParams(RasterDataStore store,
                                       int minx,
                                       int miny,
                                       int maxx,
                                       int maxy,
                                       BandList bandList)

Creates a parameter object for building a buffer. For this call the buffer type is read-only.

Returns:

BufferParam

Throws:

IOException

createBuffer

Buffer createBuffer(BufferParam param)
             throws BufferCreationException

Creates a buffer with the selected parameters

Parameters:

param -

Returns:

Throws:

BufferCreationException
