Introduction

Cell coordinates are pre-computed but free x-y-grid coordinates are also possible. Percent text info is centered on a white background area of 50 pixels width, at left side of polygonal shape.

$ui->setFillWay('reverse');
$ui->setOrientation(HTML_PROGRESS_POLYGONAL);
$ui->setCellAttributes('width=10 height=10');
$ui->setCellCoordinates(4,4);          // square 4x4

Loop to run the progress


do {
    $bar->display();
    if ($bar->getPercentComplete() == 1) {
