I want to create auto Thumbnail if i upload my PDF, then i will save that path
i build my website with yii framework
i want to try capture with ImageMagick
Any Body Help..
Thx
I am also using Yii framework to generate the image file. It is pretty simple and straight forward. I am using window XP/apache and php 5.4
Download and install the imagemagick http://www.imagemagick.org/script/download.php
Download and install php extension for imagemagic http://pecl.php.net/package/imagick
Download and install the ghostscript because image magic use the ghost script to convert the pdf to images http://www.ghostscript.com/download/
Write a method in your model class to handle conversion
use command : command format OR
use library : php manual
Call the method after your form submission.
check if the image is saved at the desired location. I hope that help. Let me know if you face any issue.
I know you asked about ImageMagick but maybe you could use GD instead to accomplish such simple operation.
It's available virtually on every hosting.
Examples in comments below docs.

I am scratching my head with this one, how can you get a screenshot or a thumbnail of a PDF? I am developing a social feed on a web server I have no control over, there is a PDF class but I cant narrow down what it is, and theres no function in there for this task.
To do this serverside, you could use ImageMagick. This allows PDF's to be converted into images on the server, not having to depend on the client's browser to have certain software.
You do need to be able to install ImageMagick on the server though.
A link to a guide can be found here
You can use google docs
https://docs.google.com/viewer?a=bi&pagenumber=1&url=http://url-of-your-pdf.pdf
It returns a png of the first page, you can then edit it using Imagemagick or similiar
Idea from: How to create thumbnails/screenshots out of PDF files on my Linux server?
I want to convert pdf files to jpg without use of imagemagick and ghostscript, if anyone have an idea please help me.
Try using an online conversion service instead.
For example transloadit provides an API which can be used to extract images from PDF files (https://transloadit.com/docs/extracting-images-of-documents). They even provide ready development kits for PHP (https://transloadit.com/docs/development-kits#php-sdk).
Cloudinary could be an alternative as well.
If you instead what to work around the error with ghostscript open another question with detailes for that provided.
How do I get a coordinate (x,y) of an image from the PDF file using PHP?
For example, I have a PDF document page, I know the size of the page, there I have one image, I know its size too (because I've extracted it using the pdfimages tool). However, I need to know where was this image situated on the page.
I've read that it maybe could be done using FPDF but I couldn't understand how.
To get PDF images with their coordinates, ImageData and size informations, you have to get PDFlib You can get the PECL free version here and TET (Text Extraction Toolkit) here.
After configuring PDFlib and TET and linking both of them to your php's extension on the php.ini (extension=pdf.so and extension=php_tet.so), you will have a bunch of examples in the directory where you installed PDFlib (where you typed ./configure && make && make install or where you get the "php_tet.so"). Open them to see how to use the functions. This lib is object oriented.
With it you can get all the images (coordinates, size and create a jpeg file) and texts (size, font and coordinates) of each pages of a PDF.
I'm at your service if you have other questions or if a point is not clear to you ;)
P.S Sorry my english is not very good
An option would be to convert your pdf to an image (there are scripts available to do so, didn't try it but this might do the job)
Then you can use the code I posted on your other question to locate an image inside another image.
I am generating a PDF using the TCPDF library and would like to convert the pdf to an image. Anyone know if this is possible with TCPDF itself (I've looked over the code but doesn't look possible)?
Looking at previous questions on here it appears the best method is to use ImageMagick - is that still the case?
ImageMagick and Ghostscript would be the way to go to do that. I would assume that running the gs or convert commands from the command line is a bit more efficient since you dont have to load the imagemagick extension in PHP and it cuts the overhead from using abstraction classes for the extension.
I need to include pdf files in some webpages, and I'm gettin' in troubles.
The app is a simple newspaper's archive, in which i can read right on page or download as pdf files, one file per page. What my customer can provide me is one pdf file for each page; what my customer wants from me is to navigate them in indexes (with page thumbnail) and have a read from a choosen one direcly in page; I'm using php/mysql.
I started trying out to use the <object> tag with type="application/pdf", but i found it's deprecate 'cause it's not crossplatform at all (there's no support on linux's browsers, but even my windows' firefox 3.5 couldn't show me anything).
I guessed I could transform that pdf in something different (html or simply images are good enough), but the only thing i found is ImageMagick, that I cannot use as I must install on server and I can't, as I'm not admin of that machine.
So, I'm finally looking for suggestions
Thanks
Display the pdf inline using an IFRAME. The thumbnail you can generate with imageMagik. You should be able to use the command line version of ImageMagik to resize and convert to jpg.
edit
Your best bet is to talk to the server admin and have them install php support for ImageMagik then you can use it as a class.
If you can't get support to install on the server, you will have to use the command line version.
You might be able to Google around for a library that wraps the command line, but it would be trivial to write it yourself.
With this in place you can create a large readable black and white png for each page. It should click through to the pdf.
