Array Data Encoder — data

Encodes values for a GIFTI image

data_encoder(
  values,
  encoding = c("ASCII", "Base64Binary", "GZipBase64Binary"),
  datatype = NULL,
  endian = c("little", "big", "LittleEndian", "BigEndian")
)

Arguments

values	values to be encoded
encoding	encoding of GIFTI values
datatype	Passed to `convert_binary_datatype`
endian	Endian to pass in `readBin`

Value

Single character vector

Examples

if (have_gifti_test_data(outdir = NULL)) {
   gii_files = download_gifti_data(outdir = NULL)
   L = gifti_list(gii_files[1])
   orig = L$DataArray$Data[[1]]
   encoding = attributes(L$DataArray)$Encoding
   datatype = attributes(L$DataArray)$DataType
   endian = attributes(L$DataArray)$Endian
   vals =  data_decoder(orig, encoding = encoding,
   datatype = datatype, endian = endian)
   enc = data_encoder(vals, encoding = encoding,
   datatype = datatype, endian = endian)
   enc == orig
}
