  • The array has a length equal to the flattened length.
  • Will cause an error to be launched if the MImage is not of MImage_Type_Byte type.

Examples

Basic Examples  (1)

This iterates over the data elements of an MImage:

MImage I0;
raw_t_byte* data;
mint i, len;
...
len = libData->MImage_getFlattenedLength(I0);
data = libData->MImage_getByteData(I0);
for (i = 0; i < len; i++) {
  raw_t_byte elem = data[i];
  ...
}
