這個可能有點混亂。我正在使用AMCharts和rails。 Amcharts附帶一個PHP腳本來導出名爲「export.php」的圖像Rails + AMcharts(帶出口圖片php腳本) - PHP腳本轉換爲控制器?
我想弄清楚如何將代碼放在export.php中並將其放入控制器中。
下面是代碼:
<?php
// amcharts.com export to image utility
// set image type (gif/png/jpeg)
$imgtype = 'jpeg';
// set image quality (from 0 to 100, not applicable to gif)
$imgquality = 100;
// get data from $_POST or $_GET ?
$data = &$_POST;
// get image dimensions
$width = (int) $data['width'];
$height = (int) $data['height'];
// create image object
$img = imagecreatetruecolor($width, $height);
// populate image with pixels
for ($y = 0; $y < $height; $y++) {
// innitialize
$x = 0;
// get row data
$row = explode(',', $data['r'.$y]);
// place row pixels
$cnt = sizeof($row);
for ($r = 0; $r < $cnt; $r++) {
// get pixel(s) data
$pixel = explode(':', $row[$r]);
// get color
$pixel[0] = str_pad($pixel[0], 6, '0', STR_PAD_LEFT);
$cr = hexdec(substr($pixel[0], 0, 2));
$cg = hexdec(substr($pixel[0], 2, 2));
$cb = hexdec(substr($pixel[0], 4, 2));
// allocate color
$color = imagecolorallocate($img, $cr, $cg, $cb);
// place repeating pixels
$repeat = isset($pixel[1]) ? (int) $pixel[1] : 1;
for ($c = 0; $c < $repeat; $c++) {
// place pixel
imagesetpixel($img, $x, $y, $color);
// iterate column
$x++;
}
}
}
// set proper content type
header('Content-type: image/'.$imgtype);
header('Content-Disposition: attachment; filename="chart.'.$imgtype.'"');
// stream image
$function = 'image'.$imgtype;
if ($imgtype == 'gif') {
$function($img);
}
else {
$function($img, null, $imgquality);
}
// destroy
imagedestroy($img);
?>
有一些版本在一個線程中存在,我發現在這裏:http://www.amcharts.com/forum/viewtopic.php?id=341
但是我有一種感覺,PHP代碼,因爲再上面已經改變了 - 因爲無論是實施爲我工作。
嘿DrDol,感謝您的評論!儘管如此,這仍然有點複雜。 – Elliot 2010-04-03 11:52:49
