I'm trying to find the most efficient way to display image properties in my application. I've got some strategies but would like to see if I avoid re-inventing the wheel by using some of ImageEn's built-in functionality.

Unfortunately, I can't find anything in the demos that use the TStringGridHelper and the example on this page doesn't give me enough to figure out how to use it.

Also, what are the best ways to get physical properties of images that don't have Exif data? At the very least I need:

- Date Created
- File Size
- Height & Width
- Resolution

I can get these brute force, but again, I'm hoping there's something more elegant already built into the ImageEn library.

Lastly, does ImageEn have a Exif tag for iso?

For EXIF meta-data, please see the demo:


Width, Height and DPI are available in TIOParams, e.g. ImageEnView1.IO.Params.Width:

The only ISO value in EXIF is EXIF_ISOSpeedRatings:

File size and dates are standard Windows functions. There are many Delphi examples on the web.
