Output Filenames: test_result_bad.bmp, test_result_bad.png, test_result_good.bmp, test_result_good.png.
#PHP PDF TO IMAGE WITHOUT IMAGEMAGICK CODE#
Some sample code to demonstrate (using PHP Version 5.2.17). When the only line of code I changed was ReadImage to ReadImageFile, the problem disappears entirely. The functions setImageFormat and setFormat, programmed line after line, provided no effect to changing the format to png, bmp, or gif. Initially, the first looks far more tempting, since you don't have to worry about fopen and fclose commands.īut, there is a problem with the ReadImage function! With an imagemagick object whose data was created from this function, I could scale, change the colors, and perform artistic effects upon the object, without any problems at all, but then there was a problem with saving: it seemed to be keep me stuck to the image format of the original image (in this case, a ".jpg", but it may be different elsewhere). What is the difference between ReadImage and ReadImageFile? Based by looking at the pages, you would think that they behave the exact same, except in their arguments: ReadImage takes a string containing the folder location of the file, and ReadImageFile takes a handle pointing to the file location.

We can take that raw data and put it right in an image tag with some descriptors.Getting Started Introduction A simple tutorial Language Reference Basic syntax Types Variables Constants Expressions Operators Control Structures Functions Classes and Objects Namespaces Enumerations Errors Exceptions Fibers Generators Attributes References Explained Predefined Variables Predefined Exceptions Predefined Interfaces and Classes Predefined Attributes Context options and parameters Supported Protocols and Wrappers Security Introduction General considerations Installed as CGI binary Installed as an Apache module Session Security Filesystem Security Database Security Error Reporting User Submitted Data Hiding PHP Keeping Current Features HTTP authentication with PHP Cookies Sessions Dealing with XForms Handling file uploads Using remote files Connection handling Persistent Database Connections Command line usage Garbage Collection DTrace Dynamic Tracing Function Reference Affecting PHP's Behaviour Audio Formats Manipulation Authentication Services Command Line Specific Extensions Compression and Archive Extensions Cryptography Extensions Database Extensions Date and Time Related Extensions File System Related Extensions Human Language and Character Encoding Support Image Processing and Generation Mail Related Extensions Mathematical Extensions Non-Text MIME Output Process Control Extensions Other Basic Extensions Other Services Search Engine Extensions Server Specific Extensions Session Extensions Text Processing Variable and Type Related Extensions Web Services Windows Only Extensions XML Manipulation GUI Extensions Keyboard Shortcuts ?

Now if we wanted to save it would be easy.īUT in this case I wanted to just display the converted image.
You will have to run this conversion for each page if you want the whole pdf. The “” in the pdf path is telling ImageMagick to convert the first page of the pdf. $image->resizeImage( 200, 200, imagick::FILTER_LANCZOS, 0) After that, the image conversion is a cinch. First you have to load the PDF into the class.
Instead of saving it, I wanted it to only display on page load. I needed to take PDF and convert it to an image.
With this class, it makes image modifications so much easier.
