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...

Hi,
  I want to place the following HTML statement inside an echo statement, i.e. in PHP I want to output an image that is also a link.

  All ideas will be greatly appreciated.

how to convert php pages to api

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 some words are written by UTF-8. I want to use PHP to convert them to NCR DECIMAL.

This is my words.



After Convert:



Sorry my bad English. Thanks advance

This is TEXT FILE my Source. (attach File)

Hello
I'm building a backend to allow a client to upload images to his site.
But my client has a lot of images in tiff format so i'd like to be able to convert tiff to jpg and only after that upload the image.
i'm using the command move_uploaded_file to upload the original image and then i'm resizing the image and creating a new one and delete the original. now i want to add to my script a way to convert the original tiff to jpeg, resize save and delete the original

here is my code that it's working fine:
Code: [Select]
if ($_FILES['foto']['name'] == "") {
    $dir = "images/spacer.gif";
} else {
$size = 124; // the thumbnail height
$filedir = 'img/ambientes/'; // the directory for the original image
$thumbdir = 'img/ambientes/'; // the directory for the thumbnail image
$prefix = 'small_'; // the prefix to be added to the original name
$maxfile = '200000';
$mode = '0666';
$userfile_name = $_FILES['foto']['name'];
$userfile_tmp = $_FILES['foto']['tmp_name'];
$userfile_size = $_FILES['foto']['size'];
$userfile_type = $_FILES['foto']['type'];
if (isset($_FILES['foto']['name']))
{
$prod_img = $filedir.$userfile_name;
$prod_img_thumb = $thumbdir.$prefix.$userfile_name;
move_uploaded_file($userfile_tmp, $prod_img);
chmod ($prod_img, octdec($mode));
$sizes = getimagesize($prod_img);
$aspect_ratio = $sizes[0]/$sizes[1];
if ($sizes[0] <= $size)
{
$new_width = $size;
$new_height = abs($new_width*$aspect_ratio);
}else{
$new_width = $size;
$new_height = abs($new_width/$aspect_ratio);
}
$destimg=ImageCreateTrueColor($new_width,$new_height) or die('Problem In Creating image');
$srcimg=ImageCreateFromJPEG($prod_img) or die('Problem In opening Source Image');
ImageCopyResampled($destimg, $srcimg, 0, 0, 0, 0, $new_width, $new_height, $sizes[0], $sizes[1]) or die('Problem In resampling');
ImageJPEG($destimg,$prod_img_thumb,90) or die('Problem In saving');
$uploadfile = $prod_img_thumb;
imagedestroy($destimg);
$fh = fopen($prod_img, 'w') or die("can't open file");
fclose($fh);
unlink($prod_img);
$dir = $uploadfile;
}
}
anyone can help me?

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!

Hello again

How to convert size from taken from sql as the numbers and converted to MB in php?

Hello all,

I'm having a problem with people uploading News Articles into my news database.

Right now, some of them must be using a weird font to type up their stories, because when they copy/paste their story from Word to the PHP form, it makes the ' turn into the little empty boxes.

Also, the same thing is happening to bullets.

Any idea how to make ther ' show up correctly, and the bullets to either show, or to convert their bullets to dashes.

thanks.

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.

How do I update a table and convert say, 66.249.75.215, from one column to another column as 0x249f94bd7. Both columns are varbinary. I'm using PDOConnect and this isn't working:

    $stmt = $pdo->prepare("UPDATE `download` SET `ip_address` = inet_aton(`ADDRESS`) WHERE ip_address is null;");
    $stmt->execute() ;

I'm getting the following error:

Fatal error: Uncaught PDOException: SQLSTATE[HY000]: General error: 1411 Incorrect string value: '`test`.`download`.`ADDRESS`' for function inet_aton in /home/larry/web/test/public_html/index.php:31 Stack trace: #0 /home/larry/web/test/public_html/index.php(31): PDOStatement->execute() #1 {main} thrown in /home/larry/web/test/public_html/index.php on line 31
