  Converting float to hexidecimal

  Posted by Kevin Burke on August 6, 2012 at 12:50 am

  Hello,
  I’d like to set the source text of a Text Layer to the Hex value of a color control. The following code seems right, but the text field only reads zero. If I set the value to the var color without converting, I get a long float such as 0.86274516582489. Please help! Thank you!

  var color = thisComp.layer("ColorPicker").effect("Color Control")("Color")[0];
color.toString(16);

  I found a solution – not sure if it’s the best, but it works!

  target = thisComp.layer("Colors Screen");
colorpicker = thisComp.layer("ColorPicker");
sampledColor_8bpc = 255* target.sampleImage(target.fromWorld(colorpicker.position), [0.5,0.5], true, time);
R = Math.round(sampledColor_8bpc[0]);
G = Math.round(sampledColor_8bpc[1]);
B = Math.round(sampledColor_8bpc[2]);

  outputString = "#" +R.toString(16) + G.toString(16) + B.toString(16);
outputString;
