What I want is a way to parse a PDF file into HTML with the image map (the hyperlinks) and the images must be in jpg format.
I have a Magazine Reader and I need the images and the position, href and size of each hyperlink.
The solution needs to be to run into a linux server.
Any suggestions?
Many thanks!
You should take a look to the pdf2html project or pdf2htmlEX.
That needs some tweaks to convert png to jpg as well.
This is that simple as :
convert foo.png foo.jpg
with ImageMagick tools.
See the README.

Ive a script to generate an image using imagemagick in PHP, after designing i need to create a pdf to print and this pdf need to be like a vector one, even if we zoom in the content should be crisp, but my pdf is not so, can some one guide me how to achieve this?
Do i need to convert my final png as svg? or is it possible to make pdf with PNG as vector?
I have a multi-page PDF file that has information I need to parse. The information and picture is confined to its own page. I need to extract the text and image from the PDF.
I'm using CentOS and PHP.
My attempt:
I originally tried using a combination of pdftotext and imagemagick. I converted the PDF into an image and that actually separated the pages into their own images. Unfortunately the quality of the image on the page came out very poor.
My goal:
I need to split the PDF into multiple PDFs, one per page. Then, I need to extract the image from that page with the best quality possible.
Thanks.
imagemagick does not fit to perform this task
when you need to extract images from a pdf, at their original size (i.e. the best, since any other resolution is or lesser or bigger than original), you must to use
pdfimages
http://www.foolabs.com/xpdf/download.html
(static binaries are available if you cannot compile from source)
syntax:
pdfimages file.pdf image-root
the image resulting will have the extension .ppm , unless you add the switch -j to have jpeg images as output
pdfseparate to split multi-page.pdf to 1.pdf 2.pdf … + convert 1.pdf 1.png …
pdfseparate (part of poppler) to split multi-page.pdf to 1.pdf 2.pdf …
pdfseparate multi-page.pdf ./single-pages/%d.pdf
extracts all pages from multi-page.pdf
and saves them as single page PDFs, (%d variable for page number)
mogrify (part of ImageMagick) to batch convert all single page PDFs to PNGs at your desired resolution (in DPI)
mogrify ./single-pages/*.pdf -density 300 -format png
I am trying to render an image with text and images that are on a .swf file. What i am doing is saving all the objects and their properties in an XML and then using imagemagick to render all that. the problem i am facing is that imagemagick treats fonts very different than Flash, so i don't get a perfect copy of what i see in the flash to what i see on the rendered image.
Can anyone share some light on how to match font sizes between flash an imagemagick? I would be very grateful.
Thanks!
Are you trying to save some image that you can see on the flash movie to a file? If so you can use Jpeg encoder in flash to do exactly that. Here is an example: http://designreviver.com/tutorials/actionscript-3-jpeg-encoder-revealed-saving-images-from-flash/
You still need a php or some other technology to post the data to and save it as a file so that the user can download it.
i am using Imagemagick for converting my .pdf file to .png images
but when i issue the command
$convert sample.pdf image.png
then it will convert all the pages of sample.pdf file to .png images but exactly i want to
convert a specific no. of pages(e.g. first 10 pages or page no.22 or 12 etc.)
then pleases suggest me a way to solve this issue.
and one more question is that:
when we view our .pdf files in google docs .pdf viewer then they are also in image format
but we can select and copy the text written on pages to the clipboard(simply select the text and press
Ctrl+c)
so how can i implement this so the users of my website can select the text form my images.
(there are already some discussion about it on stackoverflow but they are not very clear)
for i in {0..9} 11 21
do
convert "sample.pdf[$i]" "image_$i".png
done
Benoits answer is what you were looking for for slicing and converting a PDF in to images.
Alternatively you can use pdftk with the cat operation. This would get you the first 10 pages and generate a new sliced PDF for example.
pdftk YOUR.PDF cat 1-10 output SLICED.PDF
Regarding your second question about converting an image PDF to a PDF with text data the only way is to use a OCR tool like Tesseract for example.
The only problem is that those OCR tools are not always that exact. In other words sometimes they will not always be able to output what you read on that image.
How do I convert a EPS , DOC and PPT document to a preview image in PHP?
I need to display the image thumbnails in the list of items uploaded, how can i get the thubnail images of EPS, doc and PPT files?
You will need some library that is capable of rending these.
PHP on its own will not know how to render these file types. You could try converting the Word document and PowerPoint files to HTML, then convert the HTML into an image, there is software that can this for you.
As for the EPS, isn't that an image anyway? So you need to use a library like GD or ImageMagick into a meaningful format that they can resize for you.
