Problem with converting PDF to JPEG, Corrupt Image

[cargi]

Hi guys,

I am having a problem when uploading PDF files. I have sucessfully managed to upload one at about 20kb in size but when I try uploading a document at 500kb it isnt working and saysing 'corrupt image'. Any ideas or advice would be greatly appreciated.

Thanks,

Cargi

The first thing you are going to be asked is "can you provide an example file" and the second thing is what "version are you using" and finaly "can you post an example of your code".

Nobody can help you without the information above.

Hi there,

You can find an example at http://www.iGotMunchies.co.uk/register.php

The code I am using is as follows:

$filename = '';

$targetdir = 'uploads/menus/';


include('imagemagick_class.php');

$imObj = new ImageMagick($_FILES['image1']);

$imObj -> setVerbose(TRUE);

$imObj -> setTargetdir($targetdir);

$imObj -> Convert(jpg);
$filename = $imObj -> Save();
$imObj -> CleanUp();



$imObj2 = new ImageMagick($_FILES['image2']);

$imObj2 -> setVerbose(TRUE);

$imObj2 -> setTargetdir($targetdir);

$imObj2 -> Convert(jpg);
$filename2 = $imObj2 -> Save();
$imObj2 -> CleanUp();

Thanks

Works Ok for me using:

Code: Select all

<?php
exec("convert sample.pdf sample.jpg");
?>

I do not know what size you want but this will give a better quality image:

Code: Select all

<?php
exec("convert -density 300 sample.pdf -resize 50% sample.jpg");
?>

Hi Bronzo,

Thanks for the help, one i should of said earlier is that I am using the imagemagick_class file. This looks to be what would normally be
exec("convert sample.pdf sample.jpg");

I quess it is a problem within the imagemagick_class file then.

$command = "{$this->imagemagickdir}/convert -colorspace RGB -quality {$this->jpg_quality} '{$this->temp_dir}/tmp{$this->count}_{$this->temp_file}' '{$this->temp_dir}/tmp".++$this->count."_{$name}'";

The class file can be found at http://www.bokko.nl/projects/php-imagemagick-class

I did notice you were using a class and I have quickly tried it but I get "Imagemagick: Upload failed"; I am not that interested in finding how it works at the moment and so will not look at it any further.

If the code I posted works then it must be the class if not there must be a problem with the IM or Ghostscript install.

The class looks a bit OTT if all you want to do is upload and resize an image, this is an example of a form to do the same thing I wrote a few years ago: http://www.rubblewebs.co.uk/imagemagick/codes/thumb.php
