Best way to display image on 3.5 tft screen

Using Arduino Project Guidance
1

I am using an ESP32 with an SD card and a 3.5-inch ILI9488 TFT screen.

My goal is to display images stored on the SD card, and I have a working code snippet. However, I'm wondering which approach is the best for efficiency considering that the images will change every 10 seconds over a 24-hour period. Here are the options I'm considering:

  1. Save the images as JPEG and use a library for JPEG decoding.
  1. Save the images on the SD card as BMP files.
  1. Convert the images to a C-style array and save to sd card and then display that.

or is there any better way

here is code that works with jpg decoder lib

#include <SPI.h>
#include <FS.h>
#include <SD.h>
#include <TFT_eSPI.h>

TFT_eSPI tft = TFT_eSPI();
#include <JPEGDecoder.h>

void setup() {
  digitalWrite(15, HIGH);  // TFT screen chip select
  digitalWrite(5, HIGH);   // SD card chips select

  tft.begin();

  if (!SD.begin(5, tft.getSPIinstance())) {
    Serial.println("Card Mount Failed");
    return;
  }
  drawSdJpeg("/1.jpg", 0, 0);  // This draws a jpeg pulled off the SD Card
}

What differs between good, better and the best?

i think a experienced devleoper can give his opinion abood good and bad sides for each of them

4

What kind of efficiency are You thinking about?

5

I want render to be fast and processing time to be fast. So esp not to have lot of effort . Its better for me to prepare image in the way that is easier for esp to show to tft

6

Have you worked with png tile files to display off-line maps displayed on an ILI9488 3.5 in TFT Display?

Utilizing the sketch mentioned at the start of this topic.

Actual file name of the jpeg used:

Lily TTGO T7 V1.3 ESP32 Mini 1.jpg

Did I enter enter the jpeg's name incorrectly?
