• well i do not understand the interest to display in col vs in row! except to have a smaller ArrayBuffer.
    is it really faster?
    how to read each bit of col?
    I need to select each row and extract the bit from each byte stored in the buffer!!!
    i should missed something in the process... i'm lost

    for (let i=0; i<g.getWidth();i++) {
    // export a rotated  display
