Hi Chandrashekhar. Alpha blending and chroma keying are not directly
related to PhAB. They are capabilities of Photon drawing, so would more
likely be used in the draw function of a Photon widget, for example.
Alpha blending and/or chroma keying are also used when working with
images (eg. decoding gif's with transparency, or png's with an alpha
channel) and are represented in Photon's PhImage_t image structure.
Finally, layer alpha is supported by Photon's layering API. For more
information consult the QNX Momentics Photon documentation, especially
the chapter on "Raw Drawing and Animation".

Regards,
Max

Subject: Sample examples using alpha blending & chroma keying in PhAB
applications

I have recently started working on QNX and have till now developed some
very simple applications using PhAB. Now I want to develop some PhAB
applications implementing alpha blending & chroma keying. Before
proceeding, I would like to go through some sample application for the
same. Please suggest me where can I find them.
