TIEBitmap.LoadRawFromBufferOrStream

Declaration

function LoadRawFromBufferOrStream(Buffer: Pointer; Stream: TStream; BufferSize: Int64 = -1): Boolean;

Description

Loads an image that was saved with SaveRawToBufferOrStream.
Return True on success.

Note: When loading from a Buffer (as opposed to a Stream), pass the buffer's actual allocated size in BufferSize whenever it is known, e.g. the value returned by CalcRawSize. This lets the method detect a truncated, corrupted or untrusted buffer and raise an exception instead of reading past the end of the allocation. If omitted (-1), no such check is performed, matching the previous behavior.

Example

// Load Raw from a stream
if ImageEnView1.IEBitmap.LoadRawFromBufferOrStream( nil, ms ) then
ShowMessage('Load OK');

// Load Raw from a buffer, with bounds checking
if ImageEnView1.IEBitmap.LoadRawFromBufferOrStream( pBuf, nil, BufSize ) then
ShowMessage('Load OK');
