But somehow I need to draw one image (may be a button) on the top of another
image (say background image). As only one graphics plane is supported by
Nano-X I have no choice but to merge two images. How can I do this? Is any
API already exist for that operation?
Thanks & regards,
Aveek

: Does Nano-X provide APIs to control

No, there isn't currently support for this. All graphics operations
start in the nanox/ api layer, then move to the device-independent
engine/ layer, and are finally drawn (usually to a framebuffer, but
not always) at the driver/ layer. The layer names are also the
src/ directory names.
