Requirements
------------

[](#requirements)

You should have [Ghostscript](http://www.ghostscript.com/) >= 9.16 installed and configured.

Install
-------

[](#install)

The package can be installed via composer:

```
$ composer require vsitnikov/pdflib
```

Usage
-----

[](#usage)

Converting a PDF to set of images.

```
$pdflib = new vsitnikov\PDFLib\PDFLib();
$pdflib->setPdfPath($pdf_file_path);
$pdflib->setOutputPath($folder_path_for_images);
$pdflib->setImageFormat(\vsitnikov\PDFLib\PDFLib::$IMAGE_FORMAT_PNG);
$pdflib->setDPI(300);
$pdflib->setPageRange(1,$pdflib->getNumberOfPages());
$pdflib->setFilePrefix('page-'); // Optional
$pdflib->convert();
```

Alternatively using chaining:

```
$files = (new vsitnikov\PDFLib\PDFLib())
    ->setPdfPath($pdf_file_path)
    ->setOutputPath($folder_path_for_images)
    ->setImageFormat(\vsitnikov\PDFLib\PDFLib::$IMAGE_FORMAT_PNG)
    ->setDPI(300)
    ->setPageRange(1,$pdflib->getNumberOfPages())
    ->setFilePrefix('page-') // Optional
    ->convert();
```

Making a PDF from set of images

```
$pdflib = new vsitnikov\PDFLib\PDFLib();
$imagePaths = ["images-1.jpg","images-2.jpg"];
$pdflib->makePDF($destination_pdf_file_path,$imagePaths);
```

If in anycase code throws '\*\*\*\* Unable to open the initial device, quitting.' this type of error that means program can't create temporary files because of a permission problem, this error only comes in the Linux or Mac Oparating systems so Please check the apache log and provide necessay permissions

Other useful methods
--------------------

[](#other-useful-methods)

You can get the total number of pages in the pdf:

```
$pdfBox->getNumberOfPages(); //returns the number of pages in the pdf
$pdfBox->setPageRange(1,2); // allows you to convert only few pages in the PDF Document
$pdfBox->setImageQuality(95); // allows you to tell the quality you expect in the output Jpg file (only jpg)
$pdfBox->setDPI(300); //setting the DPI (Dots per inch) of output files
$pdfLib->setImageFormat(\vsitnikov\PDFLib\PDFLib::$IMAGE_FORMAT_PNG,$dDownScaleFactor=null);   //this will set the output image format, default it is jpg, but I recommend using pdf to png because it seems it is faster
/*
$dDownScaleFactor=integer
This causes the internal rendering to be scaled down by the given (integer
