TImageEnIO.ReplaceFileTIFF

TImageEnIO.ReplaceFileTIFF


Declaration

function ReplaceFileTIFF(const FileName: WideString): Integer;


Description

Save the current image into the specified multi-page TIFF file, replacing the image at the index specified by Params.TIFF_ImageIndex.
Because ImageEn can only write Little-endian TIFF the input file cannot be Big-endian (see TIFF_ByteOrder).


Examples

// We have a multipage tiff, named 'multipage.tif'.
// We want to change only the second page (index 1), making it negative.
ImageEnView1.IO.Params.TIFF_ImageIndex := 1; // select page
ImageEnView1.IO.LoadFromFile('D:\multipage.tif');
ImageEnView1.Proc.Negative;
ImageEnView1.IO.ReplaceFileTIFF('D:\multipage.tif');

// Update the file for the selected frame of a multi-page TIFF in a TImageEnMView
IO := TImageEnIO.Create(nil);
IO.Params.TIFF_ImageIndex := ImageEnMView1.SelectedImage; // select page
IO.IEBitmap.Assign( ImageEnMView1.IEBitmap );
IO.ReplaceFileTIFF( ImageEnMView1.MIO.LastFilename );
IO.Free;
