php生成图片的问题

[昆泽]

Code:
=============================================================
$graphValues=array(0,80,23,11,190,245,50,80,111,240,55);
header("Content-type: image/png");
$imgWidth=250;
$imgHeight=250;
$image=imagecreate($imgWidth, $imgHeight);
$colorWhite=imagecolorallocate($image, 255, 255, 255);
$colorGrey=imagecolorallocate($image, 192, 192, 192);
$colorBlue=imagecolorallocate($image, 0, 0, 255);
imageline($image, 0, 0, 0, 250, $colorGrey);
imageline($image, 0, 0, 250, 0, $colorGrey);
imageline($image, 249, 0, 249, 249, $colorGrey);
imageline($image, 0, 249, 249, 249, $colorGrey);
for ($i=1; $i<11; $i++){
imageline($image, $i*25, 0, $i*25, 250, $colorGrey);
imageline($image, 0, $i*25, 250, $i*25, $colorGrey);
}
for ($i=0; $i<10; $i++){
imageline($image, $i*25, (250-$graphValues[$i]), ($i+1)*25, (250-$graphValues[$i+1]), $colorBlue);
}
imagepng($image);


=================================================
为什么总是说"图像'http://localhost/human_racer/index.php/payment/test' 因其本身有错无法显示。"

test在你的代码中没有啊

[昆泽]

function test(){
$graphValues=array(0,80,23,11,190,245,50,80,111,240,55);
header("Content-type: image/png");
$imgWidth=250;
$imgHeight=250;
$image=imagecreate($imgWidth, $imgHeight);
$colorWhite=imagecolorallocate($image, 255, 255, 255);
$colorGrey=imagecolorallocate($image, 192, 192, 192);
$colorBlue=imagecolorallocate($image, 0, 0, 255);
imageline($image, 0, 0, 0, 250, $colorGrey);
imageline($image, 0, 0, 250, 0, $colorGrey);
imageline($image, 249, 0, 249, 249, $colorGrey);
imageline($image, 0, 249, 249, 249, $colorGrey);
for ($i=1; $i <11; $i++){
imageline($image, $i*25, 0, $i*25, 250, $colorGrey);
imageline($image, 0, $i*25, 250, $i*25, $colorGrey);
}
for ($i=0; $i <10; $i++){
imageline($image, $i*25, (250-$graphValues[$i]), ($i+1)*25, (250-$graphValues[$i+1]), $colorBlue);
}
imagepng($image);
}
=========================================================
用的是codeigniter的框架,

GD不太常用，帮顶

[xuzuning]

代码本身无误，请检查上下文

[sunshinexrain]

检查字体文件是否有，贴出的代码不全

http://localhost/human_racer/index.php/payment/test 这个地址很诡异

[昆泽]

我再看下.

[昆泽]

还是没解决......
