由于PHP的本色表参数只能支持256,为了能实现显示8色或更多的色带,我使用了参数传递的方法来实现。具体实现的代码如下:

1、生成色带图形的程序
transition.php
/*
* 功能:生成色带图形
* 程序员:wlxz
* 日期:2002-00-00
*/

Header("Content-type: image/Png");
$im = ImageCreate(255,50);
$bgcolor = ImageColorAllocate($im, 0, 0, 0);

$x = trim($_GET['x']);
$y = trim($_GET['y']);
$z = trim($_GET['z']);

for($i=0;$i $fontcol = ImageColorAllocate($im, $i*$x, $i*$y, $i*$z);
ImageLine($im, $i, 0, $i, 50, $fontcol);
}

ImagePng($im);
ImageDestroy($im);
?>

2、调用生成多个不同的图形
view_color.php
/*
* 功能:
* 程序员:向黎
* 日期:2002-00-00
*/
?>
