Hello everyone.
This is my second thread, which might be useful for those looking for the way to convert PDF file to images.
I'm trying to convert a PDF to a PNG image (at least the cover of one). I'm successfully extracting the first page of the PDF with pdftk. I'm using imagemagick to do the conversion: convert cover.pdf cover.png This works, but unfortunately the cover.png comes through incorrectly rendered (some of the alpha object in the PDF aren't rendered.

Aug 03, 2006 I am trying to convert a PDF file to a JPG file using the following code: Code. The Ghostscript version is GNU Ghostscript 7.07 (2003-05-17) Running on a Unix server I sincerely hope somebody can help me! Thanks in advance! Probably a stupid question but have to tested that 'convert' is working from PHP and that you can get images out. There are several ways you can convert a PDF to an image format such as PNG or JPEG. However if you want to batch process / automate the conversion of several PDF files then the most efficient tool for this purpose is the Ghostscript. Ghostscript is an interpreter for PDF and PostScript and is available on Windows, Unix, Linux and OpenVMS platforms. Converting the PDF. To convert a PDF file into a series of images, use the Pdf2Image class. The following properties and methods are offered: ConvertPdfPageToImage - converts a given page in the PDF into an image which is saved to disk; GetImage - converts a page in the PDF into an image and returns the image.
You can download the ghostscript binaries i.e. exe files (32-bit or 64-bit) from below link.
Steps to convert pdf to images using GhostScript:
· 1) Create a new console application in Visual Studio 2010.
· 2) Copy the below code into your application
publicstaticvoid PdfToJpg(string ghostScriptPath,string input, string output)
{
String ars = '-dNOPAUSE -sDEVICE=jpeg -r300 -o' + output + '-%d.jpg ' + input;
Process proc = newProcess();
proc.StartInfo.FileName = ghostScriptPath;
proc.StartInfo.Arguments = ars;
proc.StartInfo.CreateNoWindow = true;
Please be warned that counterfeit (fake) PL-2303HX (Chip Rev A) USB to Serial Controller ICs using Prolific's trademark logo, brandname, and device drivers, were being sold in the China market. Prolific usb to serial controller driver.
proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
proc.Start();
proc.WaitForExit()
}
Where,
ghostScriptPath: Refers to the full path of the exe file
input: Refers to the full path of the pdf file to covert.
Output: Refers to the full path of the image file name.
For eg.,
staticvoid Main(string[] args)
{
string ghostScriptPath = @'D:Program Filesgsgs9.01bingswin32.exe';
string inputFileName = @'C:test.pdf';
string outputFileName = @'E:Newtest';
PdfToJpg(ghostScriptPath, inputFileName, outputFileName);
}
· 3) Set the output type of your console application to “Windows Application”.
That’s it.
Note:
If you want know more about the options and switches available for GhostScript, please refer the GhostScript Documentation.
Thanks & Regards

tiffg4 is a black&white output device.You should use tiff24nc or tiff12nc as the output device colour PDFs - see ghostscript output devices.These will be uncompressed but you could put the resulting TIFFs through imagemagick or similar to resave as compressed TIFF.

I have been using ImageMagick for quite a sometime. It's very nice tool with a lot of features.
Install ImageMagick and run following command. This is what I used on Linux, you may have to replace
convert
with the correct one.Below command converts PDFs to CCITT Group 3 standard TIFs (Fax standard):
Also you may use GraphicsMagick, it is also similar to ImageMagick, but ImageMagick more concerns with quality than speed.

It is quite nice for a fax! ;-)
danio's answer is probably the best, if you need a color copy.

I notice also, from the linked thread, that you omitted to specify DPI for the output, hence the bad look.. If you need pure dithered B&W, you should use a higher resolution.
I also got a good looking image using NConvert
I mention it for the record, because I think you need a license to redistribute it (it is free for personal use otherwise).

Like other posts suggested, use a color format (e.g. -sDEVICE=tiff24nc) and specify a higher resolution (e.g. -r600x600):
Stephen QuanStephen Quan
setori's command does not specify the resolution to use for the tiffg4 output. The consequence is: Ghostscript will use its default setting for that output, which is 204x196dpi.
In order to increase the resolution to 600dpi, add a
-r600
commandline parameter:Also note that TIFFG4 is the standard fax format and as such it uses black+white/grayscale only, but no colors.
@jeff: Have you ever tried the
Kurt PfeifleKurt Pfeifle-dDITHERPPI=<lpi>
parameter with Ghostscript? (Reasonable values for lpi are N/5 to N/20, where N is the resolution in dpi. So for -r600
use try with -dDITHERPPI=30
to dDITHERPPI=120

I ran into the same problem with fax pages.
I was using Imagick in php and this command fixed the way it looked.
I didn't see any threshold option using 'gs' but convert may also work for you.
