To achieve that, please run the following. This example is for a Debian-based system. How do I handle files without text? Facebook Twitter LinkedIn Reddit. Previous Post Composer memory limit. Author Author name, as inscribed in the PDF file. BlockSeparator A string to be used for separating chunks of text. The default value is the empty string. CreatorApplication Application used to create the original document. EncryptionAlgorithm Algorithm used for password-protected files.
The Adobe documentation states : A code specifying the algorithm to be used in encrypting and decrypting the document : 0 : An alternate algorithm that is undocumented and no longer supported, and whose use is strongly discouraged. This algorithm is unpublished as an export requirement of the U. Department of Commerce. EncryptionAlgorithmRevision The revision number of the Standard security handler that is required to interpret this dictionary.
The revision number is : 2 : for documents that do not require the new encryption features of PDF 1. EncryptMetadata A flag coming from a password-protected file that says is the document metadata is also encrypted.
EOL The string to be used for line breaks. Filename Name of the file whose text contents have been extracted. ID, ID2 A pair of unique ids generated for the document. The second id is not clearly described in the Pdf specifications.
Images An array of objects inheriting from the PdfImage class. The class currently supports the following properties : ImageResource : a resource that can be used with the Php imagexxx functions to process image contents. Output : Echoes the image contents to the standard output. ImageData An array of associative arrays that contain the following entries : 'type' : Image type. Can be one of the following : - 'jpeg' : Jpeg image type.
Note that in the current version, only jpeg images are processed. IsEncrypted This property is set to true if the Pdf file is encrypted through some kind of password protection scheme. Keywords Keywords, as recorded in the author information part.
MaxExecutionTime Specifies a maximum execution time in seconds for processing a single file. MaxExtractedImages Maximum number of images to be extracted.
MaxSelectedPages Maximum number of pages to be selected. This quantity is expressed in thousands of "text units". The PdfToText class considers that if this value is less than , then the string specified by the Separator property needs to be appended to the result before the next group of characters. The ImageAutoSaveFormat property will define the image format to be used when generating the image files. Note that the Images property will be left empty. This flag has been introduced to save internal memory if you only need to extract images.
This is the symptom that the pdf file contains only relative positioning instructions combined with big values of text leading instructions. This may sometimes lead to out-of-order text or strings concatenated in an inappropriate way, but this option is to be preferred if you only need to index contents or focus on performance.
This is the default option. For example, the following text : this is a sam- ple text using hyphe- nated words that can split over seve- ral lines. If the time taken to process a single file may risk to take more time than the value in seconds defined for this property, a PdfToTextTimeout exception will be thrown before PHP tries to terminate the script execution.
If the time taken to process all PDF files since the start of the script may risk to take more time than the value in seconds defined for this property, a PdfToTextTimeout exception will be thrown before PHP tries to terminate the script execution. This option is useful if you want to define capture areas.
No special processing flags apply. Pages Associative array containing individual page contents. PageSeparator String to be used when building the Text property to separate individual pages. Separator A string to be used for separating blocks when a negative offset less than thousands of characters is specified between two sequences of characters specified as an array notation. The default value is a space.
Subject Subject written in the author information part. Statistics An associative array that contains the following entries : 'TextSize' : Contains the total size in bytes represented by the Postscript-like instructions that draw the document contents 'OptimizedTextSize' : Not all Postscript-like instructions for drawing page contents are significant ; since the parsing is done in pure PHP, it is very slow.
This entry gives the total size of the data that will be effectively parsed after removing the useless instructions. Text A string containing the whole text extracted from the underlying pdf file. Title Document title, as specified in the author information object. Utf8Placeholder When a Unicode character cannot be correctly recognized, the Utf8Placeholder property will be used as a substitution.
Form data extraction Extracting form data is fairly simple : use the GetFormData method and it will return you an object containing all the field values contained in your PDF file, whether they have been filled or not.
You have two ways to retrieve form data : Either by supplying an XML template, that maps actual form field names to more readable names. It provides additional features such as the ability of grouping field values together Or by relying on the default behavior, which will return the form field names as they are defined in the PDF file. Now, this is time to have a look at what is a template. This is described in the next section.
Please note that the above information could be subject to changes in future releases. Defining fields Form fields can currently be of three types : String fields Choice fields. This is typically used for radiobutton-like checkboxes, which represent a unique field that can have different value, depending on what is checked.
Choice fields allow you to associate constants to each individual value. Grouped fields. Grouped fields are virtual fields that are the result of the concatenation of several existing fields. Fill the values. Grouped fields Grouped fields allow you to create new properties, coming from the concatenation of existing fields. The required attributes are the following : name : Name of the grouped property fields : A comma-separated list of existing field names that should be grouped together separator : Separator string used to separate each component of the grouped field.
Capturing text Sometimes, it's easier to tell the PdfToText class which area s of text you want to retrieve from which page s , rather than having to struggle with regular expressions to isolate the information you want. Captures are a solution for such needs ; they allow you to define shapes of the following types : Rectangles : rectangles are used to surround areas of text whose contents you want to extract after processing.
Lines : allow you to capture lines and columns within lines when you have to process a report presented in tabular format. Areas to be captured are specified using a capture definition file or string, in XML format. A step-by-step overview Capturing areas of your PDF document will require you a few preliminary steps that involve some extra work. Determining what to capture A PDF file uses a coordinate system whose values are more or less expressed in "relative units". The second kind of information that appears between square brackets gives size information regarding the block of text immediately following it : [x Line heights are 16 in both cases.
Inside this group of lines, you can specify as many columns you want to capture in our example, only one column is defined ; its name is "Column1". It has the following attributes : name : Name of the shape.
Must be a valid PHP identifier that will be used to access this property information from the object returned by the GetCaptures method. This name must be unique. This can be a comma-separated list of pages or ranges of pages separated by an ellipsis, as in the following example : "1,2" "1, It is mainly used for capturing report lines and has the following attributes : name : Element name.
The following attributes are available : number : Page number s. The default is 0. It has the following attributes : name : Column name. This name must be a valid PHP identifier that will be used to access this property information from the object returned by the GetCaptures method. If not specified, the default value will be the empty string.
Either the width or right attribute must be specified. Capture classes reference The object returned by the GetCaptures method needs some explanation ; a distinction has been made between what is captured and how to access it.
This is an array property whose indexes are the page numbers containing the captures. Auxiliary script. Alternatively a free off-line version of software converter that works would be OK - many google searches resulted in missing links or programs that did not work for me. SHELL the pdf file open.
