PHP - Convert To Ci

Anyone know how to convert this to php?

function IntNoise(32-bit integer: x)  

    x = (x<<13) ^ x;
    return ( 1.0 - ( (x * (x * x * 15731 + 789221) + 1376312589) & 7fffffff) / 1073741824.0);    

end IntNoise function

I tried, and passing numbers to it isn't working, I am always getting 1 for a result, I should be getting anything between -1 and 1

My attempt:

function random($x){
$x = pow($x<<13, $x);
return ( 1.0 - ( ($x * ($x * $x * 15731 + 789221) + 1376312589) & 0xFFFFFF) / 1073741824.0);
}

Hi,

I have been pulling my hair out for the last week trying to figure this out and am just stuck. I have a set of PDF's (roughly 3,000) that I will need to convert to JPG's. I can do this using a batch through photoshop, but after it is done, I will need all new PDF's that are uploaded to be converted to a large JPG and a thumbnail JPG. Through my research it has appeared that the best way to do this is by using GraphicsMagick, with GhostScript. I am trying to get this to work with:

Windows 2008 rc2
IIS 7
PHP 5.3.3 Non-Thread Safe
GraphicsMagick-1.3.12-Q8
GhostScript 9.00
php_gmagick_nts.dll from http://valokuva.org/builds/

After I got everything installed on the server, it works fine through command line. I can convert a PDF to a jpg with no problems using something like:

gm convert test.pdf[0] test.jpg

However, when I use this PHP script:


<?php
//Instantiate a new Gmagick object
$image = new Gmagick('C:\inetpub\siteDir\test.pdf[0]');

//Make thumbnail from image loaded. 0 for either axes preserves aspect ratio
$image->thumbnailImage(100, 0);

header( "Content-Type: image/jpeg" );
echo $image;
?>


I get the following error:


thrown in C:\inetpub\siteDir\drawings.php on line 13
#1 {main}
#0 C:\inetpub\siteDir\drawings.php(13): Gmagick->__construct('C:\inetpub\sit....')
Stack trace:
[17-Oct-2010 18:40:46] PHP Fatal error: Uncaught exception 'GmagickException' with message 'Postscript delegate failed (C:\inetpub\siteDir\test.pdf)' in C:\inetpub\siteDir\drawings.php:13


I have tried doing this as well:


<?php
exec('gm convert C:\\inetpub\\siteDir\\test.pdf[0] C:\\inetpub\\siteDir\\test.jpg');
?>



If I do that in the command line on the server, it works without any problems. When I do that in the PHP script, I get no errors, but the conversion doesn't happen either. Does anyone have any ideas? Is there a better method for doing this? Am I just missing something? Any help would be greatly appreciated. Thanks!

Hi,

I was wondering if anyone has experience with using php to convert a powerpoint presentation on a Linux OS with Apache web server. The idea would be that a user uploads a powerpoint file that is converted server-side to individual png/jpg files for each slide so that a subset of these slides can be shown as a preview in an image slider.

Does anyone know if this can be done on a Linux OS with Apache web server? I came across some solutions for windows versions of php (http://www.php.net/manual/en/com.requirements.php).

Hope anyone can help me.

Hey guys I'm having a bit of a problem trying to convert this string to UTF-8 encoding

I've used
$strTem = mb_convert_encoding($strTem, "UTF-8", "auto");
and while that detects the correct current encoding it doesnt change it at all and utf8_encode doesnt work at all, dont know what to use.

Thanks

Hi

In sql we have dates like this 134238

In php it shows -  19:10:11  . we can make it by using date('d.m.y', $date); where $date=134238 ;

my question is how can we turn 19:10:11 in to 134238 using PHP

I'm having trouble with a few pages on xcart with the charsets. The problem we're having is that we need to have both utf-8 and iso type charsets as we're getting garbled code on some pages. What I can do is set the utf-8 on all pages and then encode the garbled code into utf-8. Is there a function that does this in PHP or any modules I can use? Thanks

I have a new project coming up, and one of the functions that this person wants is to convert word documents/pdf/html etc. to the ePub format. I've googled, but i haven't been able to find any code references for getting this accomplished...has anyone had any experience with this? Any suggestions? Any help would be appreciated! Also, I wouldn't mind an API if there even is one...

I am trying to convert colors from Hex to HSL (Not HSL to Hex). I am using a PHP function for this purpose. But It's not working properly for some colors. For example for #e04c4c the HSL should be (0, 70%, 59%) which it isn't the case with the function.

function hexToHsl($hex) {
    $red = hexdec(substr($hex, 0, 2)) / 255;
    $green = hexdec(substr($hex, 2, 2)) / 255;
    $blue = hexdec(substr($hex, 4, 2)) / 255;

    $cmin = min($red, $green, $blue);
    $cmax = max($red, $green, $blue);
    $delta = $cmax - $cmin;

    if ($delta === 0) {
        $hue = 0;
    } elseif ($cmax === $red) {
        $hue = (($green - $blue) / $delta) % 6;
    } elseif ($cmax === $green) {
        $hue = ($blue - $red) / $delta + 2;
    } else {
        $hue = ($red - $green) / $delta + 4;
    }

    $hue = round($hue * 60);
    if ($hue < 0) {
        $hue += 360;
    }

    $lightness = (($cmax + $cmin) / 2) * 100;
    $saturation = $delta === 0 ? 0 : ($delta / (1 - abs(2 * $lightness - 1))) * 100;
    if ($saturation < 0) {
        $saturation += 100;
    }

    $lightness = round($lightness);
    $saturation = round($saturation);

    //return "hsl(${hue}, ${saturation}%, ${lightness}%)";
    return array($hue, $saturation, $lightness);
}

This is how I used it:
 

$templatePrimaryColor = '#e04c4c';

$templatePrimaryColor = str_replace("#", "",$templatePrimaryColor);

list($h,$s,$l) = hexToHsl($templatePrimaryColor);

$primaryColor = "hsl(${h}, ${s}%, ${l}%)";

This is the output:

echo '<pre>',print_r(hexToHsl($templatePrimaryColor)).'</pre>';

Array
(
    [0] => 0
    [1] => 99
    [2] => 59
)
1

Does anyone know what is the problem there?

Thank you.
