note 93134 added to function.imagecolorset

I had the same problem as heavyraptor2 so i made this function... <?php function imagecolorize($im,$endcolor){ //funcion takes image and turns black into $endcolor, white to white and //everything in between in corresponding gradient //$endcolor should be 6 char html color //make sure it has usable palette if (imageistruecolor($im)) { imagetruecolortopalette($im, false, 256); } //first make it gray to be sure of even results (thanks moxleystratton.com) //comment this loop if you want the output based on, for example, //the red channel (for this take a look at the $gray-var in the last loop) for ($c = 0; $c < imagecolorstotal($im); $c++) { $col = imagecolorsforindex($im, $c); $gray = round(0.299 * $col['red'] + 0.587 * $col['green'] + 0.114 * $col['blue']); imagecolorset($im, $c, $gray, $gray, $gray); } //determine end-colors in hexdec $EndcolorRGB['r'] = hexdec( substr($endcolor, 0, 2)); $EndcolorRGB['g'] = hexdec( substr($endcolor, 2, 2)); $EndcolorRGB['b'] = hexdec( substr($endcolor, 4, 2)); //determine gradient-delta's $stepR = (255-$EndcolorRGB['r'])/255.0; $stepG = (255-$EndcolorRGB['g'])/255.0; $stepB = (255-$EndcolorRGB['b'])/255.0; //aColor contains the 256 gradations between endcolor(i=0) and white(i=255) $aColor = array(); for ($i = 0; $i<=255; $i++){ $aColor[$i]['r'] = $EndcolorRGB['r'] + ($i*$stepR); $aColor[$i]['g'] = $EndcolorRGB['g'] + ($i*$stepG); $aColor[$i]['b'] = $EndcolorRGB['b'] + ($i*$stepB); } //for every color-index we now replace $gray-values for $aColor for ($c = 0; $c < imagecolorstotal($im); $c++){ $currentColorRGB = imagecolorsforindex($im, $c); $gray = $currentColorRGB['red'];//image is grayscale, so red,green and blue // should be equal. We use this number as key of aColor imagecolorset($im,$c,(int)$aColor[$gray]['r'], (int)$aColor[$gray]['g'], (int)$aColor[$gray]['b']); } }?> ---- Server IP: 209.41.74.194 Probable Submitter: 86.89.188.74 ---- Manual Page -- http://www.php.net/manual/en/function.imagecolorset.php Edit -- https://master.php.net/note/edit/93134 Del: integrated -- https://master.php.net/note/delete/93134/integrated Del: useless -- https://master.php.net/note/delete/93134/useless Del: bad code -- https://master.php.net/note/delete/93134/bad+code Del: spam -- https://master.php.net/note/delete/93134/spam Del: non-english -- https://master.php.net/note/delete/93134/non-english Del: in docs -- https://master.php.net/note/delete/93134/in+docs Del: other reasons-- https://master.php.net/note/delete/93134 Reject -- https://master.php.net/note/reject/93134 Search -- https://master.php.net/manage/user-notes.php
