MatrixBlock |
apply(FrameBlock in,
MatrixBlock out)
Encode input data blockwise according to existing transform meta
data (transform apply).
|
void |
build(FrameBlock in)
Build the transform meta data for the given block input.
|
MatrixBlock |
encode(FrameBlock in,
MatrixBlock out)
Block encode: build and apply (transform encode).
|
FrameBlock |
getMetaData(FrameBlock meta)
Construct a frame block out of the transform meta data.
|
void |
initMetaData(FrameBlock meta)
Sets up the required meta data for a subsequent call to apply.
|
void |
mergeAt(Encoder other,
int row,
int col)
Merges another encoder, of a compatible type, in after a certain position.
|
Encoder |
subRangeEncoder(IndexRange ixRange)
