Introduction

This example requires :

This example will run a polygonal (square 3x3) ProgressBar.

Cell coordinates are pre-computed (line 31) but free x-y-grid coordinates are also possible. Percent text info is centered on a white background area of 30 pixels width, at top side of polygonal shape.

Lines 34 thru 56 allows to rotate cell coordinates list and start at different origin.

 Render options

Here are options to build this progress bar string (percent text info): 
valign = top
align  = center
height = 30
HTML_Progress_UI::setStringAttributes()
Here are options to build the progress bar cells : 
width  = 20
height = 20
HTML_Progress_UI::setCellAttributes()
