Parameters
| Parameters | Description |
| Stream: TStream | Specifies the stream from which the binary field’s value of the tag is copied. |
Description
Use LoadFromStream to copy the contents of a stream into the binary field of the frame. LoadFromStream always sets the Position of the source stream to 0, before streaming in the number of bytes indicated by the source stream’s Size property.
LoadFromStream reallocates the internal buffer of the binary field so that the contents of the stream will exactly fit. It sets the DataSize property accordingly, and then rea the entire contents of the stream into the binary field. Thus, LoadFromStream will discard any pre-existing data stored in the binary field of the tag.
Example: var
MS: TMemoryStream;
begin
JvID3v21.Open;
MS := TMemoryStream.Create;
try
Image1.Picture.Bitmap.SaveToStream(MS);
TJvID3PictureFrame.FindOrCreate(JvID3v21, ptArtist).LoadFromStream(MS);
finally
MS.Free;
end;
JvID3v21.Commit;
end;
