Hi and a happy new year!

We use the following code to get the tiff compression of a file:


//get compression
      iemv1.MIO.ParamsFromFile(current_file);
      originalTIFFCompression := iemv1.MIO.Params[0].tiff_compression;
//load file
      iemv1.LoadFromFileOnDemand(current_file);


this is very slow if the file is large (+700 pages per tiff)
How can we speed up this, because its okay to load the compression for the first page for us?

Thanks & with best regards, Thomas.

Hi Nigel, this speeds up our approach from 40 to 1 second, thanks a lot!!
With best regards, Thomas.

Hi Thomas

How about if you use an TImageEnIO object.

io := TImageEnIO.Create(nil);
io.ParamsFromFile(current_file);
originalTIFFCompression := io.Params.tiff_compression;
io.Free();
