Converts a BLOB variable into one of the supported storage types at a specified position in the buffer.
Syntax:
BufSetBlob(variable reference, position, value, storage, value as pointer)
Parameters:
variable reference – The reference to the BLOB variable containing the buffer. For example, 'A'VAR
position – The numeric value defining where the conversion result will be placed in the BLOB value.
value – The value to be set.
storage – A numeric value representing a valid storage type in Magic xpa. For a list of storage types, see Magic xpa Storage Types.
value as pointer – A logical value indicating if the Alpha value should be written directly to the buffer or as a pointer to the data. If you enter True, Magic xpa writes the Alpha value as a pointer.
Returns:
True when the conversion succeeds. False when the conversion fails.
The function fails when the:
Variable reference does not refer to a valid variable identifier.
Variable reference does not refer to a BLOB variable.
Position parameter has a negative value.
Storage parameter does not contain a valid number.
