Displaying a PNG image from the Internet using the TFT_eSPI library ?

[DaradiciLevente]

Is it possible to display a PNG image found on the Internet that has dimensions of 220 x 132 and is an 8-bit image on the ESP32-2432s028 screen?

The PNG images that I want to display are on a server in the local network, in a Set Top Box running a Linux OpenATV image. In fact, I want to display the icon of the current received channel. I can solve the received channel link problem, I managed to extract more data from the receiver and displayed on the ESP32-2432s028 screen. I also have a short video on YouTube showing what I have achieved so far.

I am uploading one of the images to imgur.com to show you which PNG images I want to display:

It would be ideal to display them directly from the network.

There's an example here for a jpg that will give you some ideas, it downloads the file and saves it in LittleFS:

Another example here using pngle, but the pngle decoder may not handle the 8 bit format:

See TFT_eSPI library for an example of drawing a PNG from LittleFS:

Ideally the file would be decoded as a stream so saving as a file would be unnecessary, but I do not have code for that!

I succeeded! A few days ago I posted the result on YouTube: https://youtu.be/W6XjNbb6O5A
Thanks to the code you provided, I finished my project and made it public. The description of the video describes everything necessary to make a functional replica. Thanks again for the TFT_eSPI library, all the examples in this library! Maximum respect for the work done! And last but not least, respect for the fact that you made these libraries and everything related to them public!
