Simplify Image Conversion

[Ayush4441]

Hi,
I am using a webpage to convert images to C-style header files: File to C Array Converter. It easily converts images to arrays of bytes. I use this method for projects on NodeMCU boards, but I'm facing issues with Raspberry Pi Pico. The bin2c tool doesn't properly convert my BMP files, and ssd1306_bmp_show_image_with_offset doesn’t display my image.

Is there a way to draw my image using the output from the File to C Array Converter?

My Example:

#include <hardware/i2c.h>

#define DISPLAY_SCL 11
#define DISPLAY_SDA 10
#define DISPLAY_I2C i2c1
#define DISPLAY_ADD 0x3C
#define DISPLAY_HZ 800000

#include "Driver/ssd1306.h"

#define IMG_HEIGHT 64
#define IMG_WIDTH 64

// array size is 512
uint8_t *IMG = (uint8_t[]){
