| set r [expr int(255 * ($i + $j) / 16)] |
| set g [expr int(255 * (8 - $i + $j) / 16)] |
| set b [expr int(255 * ($i + 8 - $j) / 16)] |
| |
| # determining the background luminosity (YIQ space of NTSC) and choosing |
| # the foreground color accordingly in order maintain maximum contrast |
| |
| if { [expr ($r*0.29894)+($g*0.58704)+($b*0.11402)] > 128} { |
| set cssclass "dark" |
| } else { |
| set cssclass "bright" |
| } |
| |
| puts [format "<td bgcolor=\"%02x%02x%02x\" class=\"%s\">$r $g $b</td>" $r $g $b $cssclass] |
| } |
| puts "</tr>" |
| } |
| puts "</table>" |
| puts "</body></html>"</pre> |
| <p style="width:90%"> |
| In another simple example, we dynamically generate a table selecting a |
| different background color for each cell. The font color is determined |
| through a simple CSS rule embedded in a HTML <style> element. |
| Create a file (e.g. color-table.tcl) and put the following code in it |
| If you read the code, you can see that this is pure Tcl. We |
| could take the same code, run it outside of Rivet, and it |
| would generate the same HTML! |
| </p> |
| <p style="width:90%">The result should look something like this:</p> |
| <p> |
| <img src="../picts/color-table.png"/> |
