When this flag is set (1), the JitterMatrix will adapt to the incoming matrix planecount, type, and dimensions
dim [number, number]
Matrix data dimensions

Byte stride per dimension
dstdimend number[]
Destination dimension end position (default = all dim values minus 1).
dstdimstart number[]
Destination dimension start position (default = all 0).
interp number
Matrix interpolation flag (default = 0). When the flag is set, the input matrix will be interpolated when copied to the internal matrix.

srcdimend number[]
Source dimension end position (default = all dim values minus 1).
srcdimstart number[]
Source dimension start position (default = all 0).
type string
The matrix data type (default = "char").
- "char": Char data (0-255) - "long": Long data - "float32": 32-bit floating point data - "float64": 64-bit floating point data
usedstdim number
destdim use flag (default = 0).
When the flag is set, the destination dimension's attributes are used when copying an input matrix to an internal matrix.
usesrcdim number
srcdim use flag (default = 0).
When the flag is set, the source dimension's attributes are used used when copying an input matrix to an internal matrix.

exprfill
Evaluate an expression to fill the matrix
If a plane argument is provided, the expression is applied to a single plane. Otherwise, it is applied to all planes in the matrix. See jit.expr for more information on expressions.

Call this method multiple times for each plane you wish to fill.
