TImageEnIO.LoadFromStreamTIFF

Declaration

function LoadFromStreamTIFF(Stream: TStream): integer;

Description

Loads an image from a stream containing a TIFF file (rev. 6.0, Packbits, LZW, CCITT G.3 and G.4).

Returns the number of images contained in the stream or -1 if an error was encountered while loading, such as the file not being TIFF format (Aborting will be true). Result will always be -1 if AsyncMode=True.

Notes:
- You can abort loading by setting Aborting to true
- If StreamHeaders property is True, the stream must have a special header (saved using SaveToStreamTIFF)
- LoadFromStreamTIFF does not reset the position of the stream, so you may need to first call Stream.Position := 0;

Example

// loads a TIFF file with LoadFromStreamTIFF
var
  fs: TFileStream;
Begin
  fs := TFileStream.Create('C:\myfile.tif', fmOpenRead);
  ImageEnView1.IO.LoadFromStreamTIFF(fs);
  fs.free;
End;
