Write Metadata?

Does anyone know if it’s possible to write metadata to images files from within a Xojo app - without plugins of any kind?
Any help or pointers in the right direction would be greatly appreciated.

Thank you all in advance.

You should search the forum for “Exif”.

Richard, you asked this question before (May 2015)


Hmmm, not sure why I asked that over a year and a half ago?
Thanks Axel :slight_smile:

Probably A, B, and C :frowning:

Curious to know what those declares are, in my original (1.5 year old post) ?

Taking this a step further, does anyone know if it’s possible to write XMP metadata to an image file via a Xojo app?

So in the past I wrote some code called the IMDS, “Image meta data suite” and it could alter the image meta data without affecting the image data. However it ran into problems and was a big project in it’s own right, so I pulled it in the end.

Instead I’ve been using Apple’s CGImageDestination to create images with meta data, CGImageSource to read the meta data.

In the next couple of years, I’ll be looking into handling meta data myself again as I move to make my apps more x-plat.

Thanks Sam.
This app is only for my personal usage, so I will forget this idea, and continue writing the metadata from 3rd party apps.

Thanks everyone for all the info anyway.
