How to grab and manipulate an RGB Frame??

[RogerInHawaii]

I'me quite new to the ESP32-CAM, although I'm a retired software engineer. I've got a couple of the basic examples running but can't figure out how to do what I really want to do.

I want to grab a single RGB BMP frame, at the highest possible resolution, and then be able to grab individual RGB pixels so that I can search through the image for particular colors, plus be able to SET RGB values of individual pixels in the frame. My meager attempts so far have resulted in errors that seem to indicate insufficient memory on the ESP32-CAM board for the RGB BMP frame.

Are there any examples that will do that, or can someone provide some simple sample code to do that, ormaybe explain why it's not possible to do what I hope to do?

Thank you,

Roger Garrett
