Hi All, I am new on this forum. I just started to assess the possibilities of DNG (and its SDK) for my photo processing pipeline. Being able to add (semi-) transparent pixels to sets of photos is one of my requirements, and since DNG SDK v1.4 this seems supported. Also, I was wondering how these transparent are pixels would be treated when popular end-user tools such as LightRoom and Adobe Camera Raw are used to further post-process the resulting DNGs.
I searched this forum and skimmed the DNG SDK source code, but effectively I haven't been able to generate results.
Does anyone have pointers here to:
- Sample DNG file(s) with transparent layer ?
- Code snippets for adding/accessing (an existing image as) a layer in an existing DNG file ?
