[quote author=Barand link=topic=104809.msg418296#msg418296 date=1155939823] Create a php file like this, called, say,  'gradient_image.php' [code]<?php // put your class code here // or include a file containing the class code $image = new gd_gradient_fill(100,10,'horizontal','#ff0000','#00cc00',9,number_format($newArray['song_Rating'],4)); header ("content-type: image/png"); imagepng ($image); imagedestroy ($image); ?>[/code] Now you can use your image tag [code]<IMG src="gradient_image.php">[/code] [/quote] Thank you for suggestion it works with some mods :) [code]img src="image.php?rating=<?=number_format($newArray['song_Rating'],4);?>[/code] and this is the image.php file: [code]<?php require_once "_global.php"; $image = new gd_gradient_fill(100,10,'horizontal','#ff0000','#00cc00',9,$_REQUEST['rating']); ?>[/code] ;D ;) :)

the onlu possible solution that I see is to store the image temperally on a disk... and then in the image creatiion file do something like this: [code] imagejpeg($im2, "".$imgstr.".jpeg", 100); print $myimg = $imgstr.".jpeg";[/code] and in the file you want to see that image: [code]<img src=" <? $image = new gd_gradient_fill(100,10,'horizontal','#ff0000','#00cc00',9,number_format($newArray['song_Rating'],4)); ?> " />[/code] :-\

The image that is being created requires parameters and I need to pass them somehow, either by putting the image creating into a function or a class... and for some reason it doesn'tt work like that

This is the code of rating.php file [code]<? class gd_gradient_fill { // Constructor. Creates, fills and returns an image function gd_gradient_fill($w,$h,$d,$s,$e,$step=0,$r) { $this->width = $w; $this->height = $h; $this->direction = $d; $this->startcolor = $s; $this->endcolor = $e; $this->step = intval(abs($step)); // Attempt to create a blank image in true colors, or a new palette based image if this fails if (function_exists('imagecreatetruecolor')) { $this->image = imagecreatetruecolor($this->width,$this->height); } elseif (function_exists('imagecreate')) { $this->image = imagecreate($this->width,$this->height); } else { die('Unable to create an image'); } //print " before fill "; // Fill it $this->fill($this->image,$this->direction,$this->startcolor,$this->endcolor); //print " fill "; // Show it $this->display($this->image,$r); // Return it return $this->image; } // Displays the image with a portable function that works with any file type // depending on your server software configuration function display ($im,$r) { // $colorGrey=imagecolorallocate($im, 192, 192, 192); // imageline($im, 0, 0, 0, $height, $colorGrey); // imageline($im, 0, 0, $width, 0, $colorGrey); // imageline($im, $width-1, 0, $width-1, $height-1, $colorGrey); // imageline($im, 0, $height-1, $width-1, $height-1, $colorGrey); $r = $r * 10; if ($r == 0) {$r = 1;} $im2 = imagecreatetruecolor($r,10); imagecopy($im2,$im,0,0,0,0,$r,10); if (function_exists("imagepngX")) { //header("Content-type: image/png"); //imagepng($im2,"/images/x.png"); //imagepng( } elseif (function_exists("imagegifX")) { //header("Content-type: image/gif"); //imagegif($im2); } elseif (function_exists("imagejpeg")) { header("Content-type: image/jpeg"); imagejpeg($im2, "", 100); } elseif (function_exists("imagewbmp")) { header("Content-type: image/vnd.wap.wbmp"); imagewbmp($im); } else { die("Doh !
