Load an image from raw pixels data

[andre.a...@gmail.com]

Hi, I am trying to create a camera service, but I can't find any way to push the raw pixels from the binary channel to an ui.Image. 

I found that decodeImageFromList only decodes an image from memory in some specific format like PNG. Is there any way to 

create an Image from uncompressed bitmap data, based on width, width step, height and in the pixels format (BGRA, RGBA,...) ?

If not, can this be done in canvas?

Thanks

decodeImageFromList should support BMP, which basically just encodes that information into the start of the byte stream:

In that case, I need to create another byte buffer to add that information, I was expecting a way to access directly to the camera buffer without performing a new copy in each frame.

That makes sense.  Would you be willing to file an issue?  It should be pretty easy to add a function that takes the raw data and the size/stride as separate arguments.

Done.
