c++ – Trouble reading integer metadata from file

Trying to read the file size data from a bitmap file. I know that I have the offset (0x02) correct and can find the correct file size in a hex editor.

uint32_t getBMPSize(string bmpPath) {
    char sizeread[2] = {};

    uint32_t size;

    ifstream bmpFile;

    bmpFile.open(bmpPath);

    uint16_t offset = 0x02;
    if (bmpFile.is_open()) {


        bmpFile.seekg(offset);
        bmpFile.read(sizeread, 1);

        bmpFile.close();
    }


    size = *sizeread;

    // Convert size from little-endian to big endian
    size = (size >> 24) |
        ((size << 8) & 0x00FF0000) |
        ((size >> 8) & 0x0000FF00) |
        (size << 24);
    



    return size;
}

I am expecting to get (8A 7B 0C 00) returned to sizeread. This should then be converted to a big-endian 32bit unsigned integer as 818058. As it stands now, the function returns 2332033023.
