Posted - Oct 24 2020 : 11:34:29 Occasionally, the usage of TImageEnMIO.SaveToFileTIFF(FileName, True) or TImageEnMIO.SaveToFile(FileName, ioTIFF, True) generates an incomplete, 174 byte sized TIF File which can't be opened.
Curious: Without closing the application and after saving the TImageEnMView Bitmaps in other formats (e.g. JPG, PDF) the saving in TIF format finally succeeds.
Has anyone made a similar experience with TImageEnMIO.SaveToFileTIFF and got a workaround to fix this behaviour?

Posted - Oct 25 2020 : 23:04:07 I tried to reproduce as follows, but did not experience any issues:
ImageEnMView1.AppendImage('D:\im.jpg');
ImageEnMView1.AppendImage('D:\alpha.png');
ImageEnMView1.AppendImage('D:\im2.jpg');
ImageEnMView1.AppendImage('D:\im3.jpg');
ImageEnMView1.AppendImage('D:\wic.bmp');
for I := 1 to 50 do
begin
fn := 'D:\test'+IntToStr(Random(10000))+'.tif';
ImageEnMView1.MIO.SaveToFileTIFF( fn );
end;
Posted - Oct 25 2020 : 07:37:28 I made a quite simple test with some buttons, each to save the TImageEnMView bitmaps in a different format (TIF, JPG).
After opening the app and loading a few bitmaps in TImageEnMView, saving one or more of them as TIF fails. If then (with the same app still open, therefore the same hardware conditions) I save the bitmaps as JPG (works correctly) and retry to save them as TIF, the TIF saving succeeds. It seems as if saving a single bitmap as JPG corrects something. In fact, if TImageEnMView contains only one bitmap, TIF saving works correctly right from the start.

Sounds like some kind of drive caching issue. Does it only happen on a particular drive? What about when you test on an external hard drive?
