Hi

Is it possible to save EXIF data to a PNG image?

I notice that in ImageEN there is a InjectJpegEXIF and an InjectTIFFEXIF method but not one for PNG images.

I seem to be able to read EXIF data info from a PNG, but can't see how to edit it and resave it.

Bruce.

PNG does not embed EXIF info. So, no you can not edit it.

Hi

With PNG, you can use TextKeys instead:
