The method iewic>IEWicWrite(..) I believed saves an image data using any WIC codec not only TIFF. However there's a conditional compiler directive as follows:
{$ifdef IEINCLUDETIFFHANDLER}
IEInjectTIFFEXIF(Stream, Stream, '', '', 0, IOParams);
{$endif}
The IEINCLUDETIFFHANDLER is defined in my application. When I save JPEG or PNG through WIC I get unreadable file by even default image viewer in Windows. The reason is obvious, there's a TIFF Exif written in
When I comment it out the output is readable then.
