I had a previous post about corrupt TIFFs. I used similar code to the following...

"ImageEn can test if a file is corrupted, but only after loaded (or tried to load) it. Example:

ImageEnView1.IO.LoadFromFile('TIFFTest.tif');
if ImageEnView1.IO.Aborting then
...corrupted..."

The only problem is that if the image file has a size of zero bytes it does not get marked as corrupt. Any ideas?

I cannot replicate this (at least using 4.x versions). Please try:

with TFileStream.Create('empty.tiff', fmCreate) do
  Free();
ImageEnView1.IO.LoadFromFile('empty.tiff');
if ImageEnView1.IO.Aborting then
  showmessage('aborting');


"aborting" is correctly displayed in my tests.
