Re: ESP32 CAM direct access to image data

From studying generally about image formats online I'm now guessing that "Channel" is the R, G or B channel. If so, are the channel numbers 0,1,2 or 1,2,3 or something else? Are they in R then G then B order? From your earlier comments, perhaps the order is obvious to experienced programmers in this...

I knew what "greyscale" meant in the general sense, but I had no way to know that, in this case, it means 8 bits, so your explanation is helpful Anyhoooo - should I assume that this 8-bit data is organised as a 2D array of bytes? Are there headers or footers o...

Re: ESP32 CAM direct access to image data

I am also interested in this. Can someone please tell me where the real, detailed documentation is on the functions provided? For example where do I find these answers: 1. What is the format of PIXFORMAT_GRAYSCALE, for example? 2. Where is the list of all the possible formats? 3. Where is the list o...
