Some server are not allowing GS and have comparable issue with ImageMagick, Currently i am utilizing some js which transform pdf pages to image information and then app send out that information to server for developing image. Is there any bundle which just render pdf and create images of all pages without using GS And ImageMagick.
I don’t want any package to install on server for this, I simply whatever for it is incorporated in my app when other install that app, they didn’t get any notification for dependency, End product must be one click install.
transloadit supplies an API which can be used to draw out images from PDF files (https://transloadit.com/docs/extracting-images-of-documents).
I’m using a c# code to convert PDF to JPG. That works however the quality is very bad.
One more thing, I desire to keep the original size of the PDF however the conversion crops the size of the JPG.
It can be done using setResolution, however you require to do it prior to loading an image. Try something like this:
The quality of the image produced from the PDF can be changed by setting the density (which is the DPI) before reading in the PDF – this gets past to ghostscript below which rasterizes the PDF. To obtain a good result, supersample at double the density you need, and utilize resample to get back to the wanted DPI. Remember to change the colorspace to RGB if you want an RGB JPEG.
A normal command line version for transform might be:
$im = new Imagick();
If you need to crop it, a -shave command following the resample is usually reasonable, if the image is centred within the page.
convert -density 600 document.pdf -colorspace RGB -resample 300 output.jpg
When it comes to the PHP IMagick extension, well, I never ever personally use it – so am not sure of how you specify file reading hints to it, however I would hope it is possible.
Make sure that the PDF is created with the proper colour profiles, I as soon as had my JPG being extremely rinsed after resizing due to source file was developed with incorrect colour profile. See also: ImageMagick PDF to JPEG conversion results in green square where image should be
