I'm trying to convert a BMP in 128x32 size
for use a custom Adafruit splash screen .
Example https://github.com/adafruit/Adafruit_SSD1306/tree/master/examples/ssd1306_128x32_i2c
replace const uint8_t PROGMEM splash2_data[] in /home/youruser/Arduino/libraries/Adafruit_SSD1306/Splash.h
I got a distorted pixel mesh .

Original splash :
const uint8_t PROGMEM splash2_data[] = { 0b00000000,0b00000000,0b01100000,0b00000000,0b00000000,0b00000000,0b00000000,0b00000000,0b00000000,0b00000000,0b00000000,0b00000000,0b00000000,0b00000000,0b00000000, 0b00000000,0b00000000,0b11100000,0b00000000,0b00000000,0b00000000,0b00000000,0b00000000,0b00000000,0b00000000,0b00000000,0b00000000,0b00000000,0b00000000,0b00000000,

Updated from what I got from bin2header :

const uint8_t PROGMEM splash2_data[] = { 0x42, 0x4d, 0x8a, 0x14, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x8a, 0x04, 0x00, 0x00, 0x7c, 0x00, 0x00, 0x00, 0x80, 0x00, 0x00, 0x00, 0x20, 0x00, 0x00, 0x00, 0x01, 0x00, 0x08, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x10, 0x00, 0x00, 0x23, 0x2e, 0x00, 0x00, 0x23, 0x2e, 0x00, 0x00, 0x00, 0x01, 0x00, 0x00, 0x00, 0x01, 0x00, 0x00, 0x00, 0x00, 0xff, 0x00, 0x00, 0xff, 0x00, 0x00, 0xff, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x42, 0x47, 0x52, 0x73, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
