Hi,

Just coming back after a long period and discovering that ImageEn for FMX is back.
Thank you very much for that.

I just need to know if Chroma Key is or will be supported.

The App on a smartphone should:
- Capture a photo
- Detect and decode QR code
- Apply Chroma Key with Green screen background removal
- Insert Background Layer
- Insert Foreground PNG Layer with transparency

Thank you in advance for your clarification

Hi Bob

Firstly, at this stage, only Windows is supported. Converting the library to Android will take significant work.

We have not tested ChromaKey yet, though I cannot see any reason it wouldn't work. You might want to use the tool above to convert the demo to FireMonkey.

Thank you for your feedback Nigel

Most of my steps I described above can be performed outside the ImageEn library.
The only missing and important part is of course the Chroma Key algorithm.
May I assume that your Chroma Key code/unit written in Delphi is platform independent that could be potentially compiled for another platform ?

Or could be modified to analyse a standard FMX Image object instead of ImageEn?

Just thinking out loud...

Bob



Hi Bob

I've just pushed a FireMonkey version of the ChromaKey demo. It works fine.

Most of the low level code for bitmaps should be platform independent. But there is a lot of code around it which needs to be checked and converted. That is what will take time.

I have sent a private message using the contact form on your web site. Did you get it ?
Can I have a email address for conversation outside this forum?
