Issue Description

Hi, I have been exploring the node and python examples. I was able to play with node module to capture and save using the available examples.
However, for python wrapper, I don't get a straight forward answer to save depth and color images. I searched a lot in the issues as well but could not get a simple answer.
All i'm looking is a python equivalent of nodejs-save-to-disk.js that can save color and depth image. Please help

Hi @chain-tech The link below provides an example of Python scripting for exporting depth and color frames as PNG images using the imwrite instruction.

A more advanced example that makes use of alignment is here:

Thanks @MartyG-RealSense , I have already gone through those links you shared. But was searching a lot to see if there's more better/easier option. I will try to work more with those examples you shared.
I am wondering why the python save to disk part is more complicated compared to the node version and why there's predefined example in the list of sample examples.

Another approach to color and depth file export is to save the color as a PNG and the depth as an array of scaled matrices in an .npy file, like in the Python script in the link below.

An alternative export method is to use the save_single_frameset instruction to save each individual frame as a bag file instead of an image file.
