AppendToBinaryFile


Unit: SDL_matrix
Class: TMat4D
Declaration: procedure AppendToBinaryFile (FName: string; TSlotStart, TSlotEnd: integer);

The method AppendToBinaryFile appends selected time slots between TSlotStart and TSlotEnd to the file FName. As a prerequisite, the number of columns, the number of rows, and the number of layers of both the matrix in memory and the matrix on file must be equal; otherwise an exception is raised.

If any of the time slot parameters are zero or negative, the entire data matrix is appended. If TSlotStart is beyond the maximum time slot of the matrix an exception is raised. If TSlotStart is within the data range but TSlotEnd is beyond the maximum time slot, only the available data are saved.

Hint: The method AppendToBinaryFile triggers the OnPercentDone event to allow to implement a progress indicator when working with large files.
