I use TImageVect to analyze and modify Dicom files.
For example I change the brightness:

ImageVect.IEBitmap.ChannelOffset[0] := 200; // red
ImageVect.IEBitmap.ChannelOffset[1] := 200; // green
ImageVect.IEBitmap.ChannelOffset[2] := 200; // blue
ImageVect.Update;


But the file saved is not changed - has the same brightness like the original. How to apply changes to destination file?


I save Dicom file this way:

SaveImageEnDialog1.AutoSetFilterFileType := ioDicom;
SaveImageEnDialog1.Filename := MyFileName;
if SaveImageEnDialog1.Execute then
begin
ImageVect.IO.SaveToFileDICOM (SaveImageEnDialog1.Filename);
end;

ChannelOffset is a "display only" property. It doesn't actually change the bitmap.
To make ChannelOffset changes permanent you should call FixChannelOffset (maybe just before SaveToFileXXX).

ImageEnVect.IEBitmap.FixChannelOffset();
