Hi all

I'm new using ImageEn, so xcuse if this is a stupid question ;-)

I'm just trying the get some EXIF info. It's working fine on jpg, but not on HEIC (coming from iPhone 13)

--> ParamsFromFile is doing an EIEException 'WIC Failure'

if ImageEnIO1.ParamsFromFile('IMG_0571.HEIC', True) then begin
  if ImageEnIO1.Params.EXIF_HasEXIFData then begin
    Orientation := ImageEnIO1.Params.EXIF_Orientation.ToString;
...

I'm on Delphi 11

Any idea ?

Hi

Are you actually able to load HEIC files with ImageEn?

You may need a driver:

Hi,

Thanks it is working now... but, why is this driver mandatory to read only the EXIF info?

Since the HEIF/HEIC driver is no longer free (Device Manufacturer tricks now ask a redeem code),
it is not possible to ask every customer to bought it...

EXIF in HEIC seems not too far from EXIF in JPG.. is it possible to implement a natif reader for this format ?

Thanks a lot

Hi

The driver is needed to load the image and meta-data. It is possible we will have native support in the future if the format gains in popularity.

It looks like this driver is now free anyway:
