I would just try converting a jpg to a png for now and look into the pdf problem if this works. Put the jpg file into the same directory as the php page and try:

Code: Select all

exec(" C:\Program Files\ImageMagick-6.8.6-Q16\convert.exe input.jpg output.png");

I would really like to get this to work as I now have time invested...and like imagemagick....but so confused right now...
does anyone know of any other PDF to PNG converters out there that can be run from PHP?
I need to grab the first page of the PDF, resize it and store in another folder...

If I run this I get this error:

Code: Select all

			$input = '/uploads/Test/17281.pdf';
			$output = '/uploads/Test/test.png';

			$cmd = "$input $output";

			echo $input.'<br>';
			echo $output.'<br>';

			$array=array(); 
			echo "<pre>"; 
			exec("convert $cmd 2>&1", $array);  
			echo "<br>".print_r($array)."<br>"; 
			echo "</pre>";

ERROR:

did see your last post...will try that...

I tried this and NO ERRORS but no .png created

exec(" C:\Program Files\ImageMagick-6.8.6-Q16\convert.exe C:\Temp\Test.jpg C:\Temp\Test.png");

echo 'DONE';

BUT I CAN do this from the command prompt with : CONVERT in.jpg out.jpg

WOULD be nice if imagemagick documentation had some documentation on how to do this from Win or Linux in a couple different languages...almost ready to scrap it but really really want to get this working...

Try this now:

Code: Select all

$array=array(); 
         echo "<pre>"; 
         exec(" C:\Program Files\ImageMagick-6.8.6-Q16\convert.exe C:\Temp\Test.jpg C:\Temp\Test.png 2>&1", $array);  
         echo "<br>".print_r($array)."<br>"; 
         echo "</pre>";

I am off to bed now!

I know nothing about PHP, so can't help there.

However, the message "Must specify a file system" comes from Microsoft convert, a utility that converts one filesystem into another. So your script successfully calls a program, but the wrong one.

As suggested, putting the full path to ImageMagick convert will remove that problem.

snibgo has a good point!

see http://www.imagemagick.org/Usage/windows/#convert_issue

or http://savage.net.au/ImageMagick/html/i ... nvert.html

where the other solution is to rename the IM convert.exe to something like imconvert.exe

thanks for all your thoughts....going to look at those links...

Bonzo...I added your bit of code...and got the below.

[1] => operable program or batch file.

I went to the links posted and read about setting the regedit...I did this via the setting the HKEY_CURRENT_USER as specified on my server. SO CHANGING the HKEY to try and default the IMageMagick convert.exe seems to have worked? I think

I now run this code: and I get

Code: Select all

$input = chmod("156.142.2.31:84/inetpub/wwwroot/ImageUpload/uploads/Test/17281.pdf[0]", 0755);
$output = chmod("156.142.2.31:84/inetpub/wwwroot/ImageUpload/uploads/Test/test.png", 0755);
			
$cmd = "$input $output";
$array=array(); 
echo "<pre>"; 
exec("convert $cmd 2>&1", $array);  
echo "<br>".print_r($array)."<br>"; 
echo "</pre>";

OK with the last post seemingly now the correct convert is working I tried the below and am now getting this error
Getting permission errors...do I need to open permissions in IIS or on the folders themselves...
I have EVERYONE group set to full rights on the uploads folder...

oh yea I move the ImageMagick folder that has the convert to my website location for testing.

Code: Select all

$array=array(); 
echo "<pre>";

I do not know about permissions on Windows servers.
I would presume the code needs the path to the program but the code then needs the relative/absolute path of the image from the code.

Code: Select all

$array=array(); 
echo "<pre>"; 
// Input test.jpg and Test.png in the same folder as the php page
exec(" C:\inetpub\wwwroot\ImageUpload\ImageMagick-6.8.6-Q16\convert.exe test.jpg Test.png 2>&1", $array);        
echo "<br>".print_r($array)."<br>"; 
echo "</pre>"; 
echo 'DONE';

Think I got it (obviously with your help...very much appreciated..)....more testing ..... BRB....very excited...

Well not so fast....

If I do this with a jpg to png conversion it works great...

Code: Select all

$array=array(); 
echo "<pre>";

echo "<br>".print_r($array)."<br>"; 
 echo "</pre>";

But if I try it with a PDF I get these errors

exec(" C:\inetpub\wwwroot\ImageUpload\ImageMagick-6.8.6-Q16\convert.exe uploads/17364.pdf uploads/thumbs/Test.png 2>&1", $array);

I assume ghostscript is installed but you can run this to find out > change your path to convert:

Code: Select all

<?php
echo "<pre>";
system ("convert -list Delegate");
system ("convert -list format");
echo "</pre>";
?>

Did that and I got this huge list....

Maybe ghostscript is not installed? I am very confused...Its not in the imagemagick folder containing the convert.exe....so maybe its not installed..

Where do I go to download and what version? GhostPCL, GhostPDF, GhostXPS, MuPDF???????????
