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.

https://www.imageen.com/HELP/IMAGEEN/TStringGridHelper.NewGridForExif.html

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?

Thanks!

Hi

For EXIF meta-data, please see the demo:

\Demos\InputOutput\EXIF\EXIF.dpr


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.
