# Tesseract OCR for PHP
|
||||
|
||||
A wrapper to work with Tesseract OCR inside PHP.

|
||||
|

## Installation
|
||||
|
||||
Via [Composer][]:
|
||||
|
||||
$ composer require thiagoalessio/tesseract_ocr
|
||||
|
||||
:bangbang: **This library depends on [Tesseract OCR][], version _3.02_ or later.**
|
||||
|
||||
<br/>
|
||||
|
||||
### ![][windows_icon] Note for Windows users
|
||||
|
||||
There are [many ways][tesseract_installation_on_windows] to install
|
||||
[Tesseract OCR][] on your system, but if you just want something quick to
|
||||
get up and running, I recommend installing the [Capture2Text][] package with
|
||||
[Chocolatey][].
|
||||
|
||||
choco install capture2text --version 3.9
|
||||
|
||||
:warning: Recent versions of [Capture2Text][] stopped shipping the `tesseract` binary.
|
||||
|
||||
<br/>
|
||||
|
||||
### ![][macos_icon] Note for macOS users
|
||||
|
||||
With [MacPorts][] you can install support for individual languages, like so:
|
||||
|
||||
$ sudo port install tesseract-<langcode>
|
||||
|
||||
But that is not possible with [Homebrew][]. It comes only with **English** support
|
||||
by default, so if you intend to use it for other language, the quickest solution
|
||||
is to install them all:
|
||||
|
||||
$ brew install tesseract tesseract-lang
|
||||
|
||||
<br/>
|
||||
|
||||
## Usage
|
||||
|
||||
### Basic usage
|
||||
|
||||
<img align="right" width="50%" title="The quick brown fox jumps over the lazy dog." src="./tests/EndToEnd/images/text.png"/>

```php
|
||||
use thiagoalessio\TesseractOCR\TesseractOCR;
|
||||
echo (new TesseractOCR('text.png'))
|
||||
->run();
|
||||
```
|
||||
|
||||
```
|
||||
The quick brown fox
|
||||
jumps over
|
||||
the lazy dog.

|
||||
### Breaking CAPTCHAs
|
||||
|
||||
Yes, I know some of you might want to use this library for the *noble* purpose
|
||||
of breaking CAPTCHAs, so please take a look at this comment:
|
||||
|
||||
<https://github.com/thiagoalessio/tesseract-ocr-for-php/issues/91#issuecomment-342290510>
|
||||
|
||||
## API
|
||||
|
||||
### run
|
||||
|
||||
Executes a `tesseract` command, optionally receiving an integer as `timeout`,
|
||||
in case you experience stalled tesseract processes.
|
||||
|
||||
```php
|
||||
$ocr = new TesseractOCR();
|
||||
$ocr->run();
|
||||
```
|
||||
```php
|
||||
$ocr = new TesseractOCR();
|
||||
$timeout = 500;
|
||||
$ocr->run($timeout);
|
||||
```
|
||||
|
||||
### image
|
||||
|
||||
Define the path of an image to be recognized by `tesseract`.
|
||||
|
||||
```php
|
||||
$ocr = new TesseractOCR();
|
||||
$ocr->image('/path/to/image.png');
|
||||
$ocr->run();
|
||||
```
|
||||
|
||||
### imageData
|
||||
|
||||
Set the image to be recognized by `tesseract` from a string, with its size.
|
||||
This can be useful when dealing with files that are already loaded in memory.
|
||||
You can easily retrieve the image data and size of an image object :
|
||||
```php
|
||||
//Using Imagick
|
||||
$data = $img->getImageBlob();
|
||||
$size = $img->getImageLength();
|
||||
//Using GD
|
||||
ob_start();
|
||||
// Note that you can use any format supported by tesseract
|
||||
imagepng($img, null, 0);
|
||||
$size = ob_get_length();
|
||||
$data = ob_get_clean();
|
||||
|
||||
$ocr = new TesseractOCR();
|
||||
$ocr->imageData($data, $size);
|
||||
$ocr->run();
|
||||
```
|
||||
|
||||
### executable
|
||||
|
||||
Define a custom location of the `tesseract` executable,
|
||||
if by any reason it is not present in the `$PATH`.
|
||||
|
||||
```php
|
||||
echo (new TesseractOCR('img.png'))
|
||||
->executable('/path/to/tesseract')
|
||||
->run();
|
||||
```
|
||||
|
||||
### version
|
||||
|
||||
Returns the current version of `tesseract`.
|
||||
|
||||
```php
|
||||
echo (new TesseractOCR())->version();
|
||||
```
|
||||
|
||||
### availableLanguages
|
||||
|
||||
Returns a list of available languages/scripts.
|
||||
|
||||
```php
|
||||
foreach((new TesseractOCR())->availableLanguages() as $lang) echo $lang;
|
||||
```
|
||||
|
||||
__More info:__ <https://github.com/tesseract-ocr/tesseract/blob/master/doc/tesseract.1.asc#languages-and-scripts>
|
||||
|
||||
### tessdataDir
|
||||
|
||||
Specify a custom location for the tessdata directory.
|
||||
|
||||
```php
|
||||
echo (new TesseractOCR('img.png'))
|
||||
->tessdataDir('/path')
|
||||
->run();
|
||||
```
|
||||
|
||||
### userWords
|
||||
|
||||
Specify the location of user words file.
|
||||
|
||||
This is a plain text file containing a list of words that you want to be
|
||||
considered as a normal dictionary words by `tesseract`.
|
||||
|
||||
Useful when dealing with contents that contain technical terminology, jargon,
|
||||
etc.
|
||||
|
||||
```
|
||||
$ cat /path/to/user-words.txt
|
||||
foo
|
||||
bar
|
||||
```
|
||||
|
||||
```php
|
||||
echo (new TesseractOCR('img.png'))
|
||||
->userWords('/path/to/user-words.txt')
|
||||
->run();
|
||||
```
|
||||
|
||||
### userPatterns
|
||||
|
||||
Specify the location of user patterns file.
|
||||
|
||||
If the contents you are dealing with have known patterns, this option can help
|
||||
a lot tesseract's recognition accuracy.
|
||||
|
||||
```
|
||||
$ cat /path/to/user-patterns.txt'
|
||||
1-\d\d\d-GOOG-441
|
||||
www.\n\\\*.com
|
||||
```
|
||||
|
||||
```php
|
||||
echo (new TesseractOCR('img.png'))
|
||||
->userPatterns('/path/to/user-patterns.txt')
|
||||
->run();
|
||||
```
|
||||
|
||||
### lang
|
||||
|
||||
Define one or more languages to be used during the recognition.
|
||||
A complete list of available languages can be found at:
|
||||
<https://github.com/tesseract-ocr/tesseract/blob/master/doc/tesseract.1.asc#languages>
|
||||
|
||||
__Tip from [@daijiale][]:__ Use the combination `->lang('chi_sim', 'chi_tra')`
|
||||
for proper recognition of Chinese.
|
||||
|
||||
```php
|
||||
echo (new TesseractOCR('img.png'))
|
||||
->lang('lang1', 'lang2', 'lang3')
|
||||
->run();
|
||||
```
|
||||
|
||||
### psm
|
||||
|
||||
Specify the Page Segmentation Method, which instructs `tesseract` how to
|
||||
interpret the given image.
|
||||
|
||||
__More info:__ <https://github.com/tesseract-ocr/tesseract/wiki/ImproveQuality#page-segmentation-method>
|
||||
|
||||
```php
|
||||
echo (new TesseractOCR('img.png'))
|
||||
->psm(6)
|
||||
->run();
|
||||
```
|
||||
|
||||
### oem
|
||||
|
||||
Specify the OCR Engine Mode. (see `tesseract --help-oem`)
|
||||
|
||||
```php
|
||||
echo (new TesseractOCR('img.png'))
|
||||
->oem(2)
|
||||
->run();
|
||||
```
|
||||
|
||||
### dpi
|
||||
|
||||
Specify the image DPI. It is useful if your image does not contain this information in its metadata.
|
||||
|
||||
```php
|
||||
echo (new TesseractOCR('img.png'))
|
||||
->dpi(300)
|
||||
->run();
|
||||
```
|
||||
|
||||
### allowlist
|
||||
|
||||
This is a shortcut for `->config('tessedit_char_whitelist', 'abcdef....')`.
|
||||
|
||||
```php
|
||||
echo (new TesseractOCR('img.png'))
|
||||
->allowlist(range('a', 'z'), range(0, 9), '-_@')
|
||||
->run();
|
||||
```
|
||||
|
||||
### configFile
|
||||
|
||||
Specify a config file to be used. It can either be the path to your own
|
||||
config file or the name of one of the predefined config files:
|
||||
<https://github.com/tesseract-ocr/tesseract/tree/master/tessdata/configs>
|
||||
|
||||
```php
|
||||
echo (new TesseractOCR('img.png'))
|
||||
->configFile('hocr')
|
||||
->run();
|
||||
```
|
||||
|
||||
### setOutputFile
|
||||
|
||||
Specify an Outputfile to be used. Be aware: If you set an outputfile then
|
||||
the option `withoutTempFiles` is ignored.
|
||||
Tempfiles are written (and deleted) even if `withoutTempFiles = true`.
|
||||
|
||||
In combination with `configFile` you are able to get the `hocr`, `tsv` or
|
||||
`pdf` files.
|
||||
|
||||
```php
|
||||
echo (new TesseractOCR('img.png'))
|
||||
->configFile('pdf')
|
||||
->setOutputFile('/PATH_TO_MY_OUTPUTFILE/searchable.pdf')
|
||||
->run();
|
||||
```
|
||||
|
||||
### digits
|
||||
|
||||
Shortcut for `->configFile('digits')`.
|
||||
|
||||
```php
|
||||
echo (new TesseractOCR('img.png'))
|
||||
->digits()
|
||||
->run();
|
||||
```
|
||||
|
||||
### hocr
|
||||
|
||||
Shortcut for `->configFile('hocr')`.
|
||||
|
||||
```php
|
||||
echo (new TesseractOCR('img.png'))
|
||||
->hocr()
|
||||
->run();
|
||||
```
|
||||
|
||||
### pdf
|
||||
|
||||
Shortcut for `->configFile('pdf')`.
|
||||
|
||||
```php
|
||||
echo (new TesseractOCR('img.png'))
|
||||
->pdf()
|
||||
->run();
|
||||
```
|
||||
|
||||
### quiet
|
||||
|
||||
Shortcut for `->configFile('quiet')`.
|
||||
|
||||
```php
|
||||
echo (new TesseractOCR('img.png'))
|
||||
->quiet()
|
||||
->run();
|
||||
```
|
||||
|
||||
### tsv
|
||||
|
||||
Shortcut for `->configFile('tsv')`.
|
||||
|
||||
```php
|
||||
echo (new TesseractOCR('img.png'))
|
||||
->tsv()
|
||||
->run();
|
||||
```
|
||||
|
||||
### txt
|
||||
|
||||
Shortcut for `->configFile('txt')`.
|
||||
|
||||
```php
|
||||
echo (new TesseractOCR('img.png'))
|
||||
->txt()
|
||||
->run();
|
||||
```
|
||||
|
||||
### tempDir
|
||||
|
||||
Define a custom directory to store temporary files generated by tesseract.
|
||||
Make sure the directory actually exists and the user running `php` is allowed
|
||||
to write in there.
|
||||
|
||||
```php
|
||||
echo (new TesseractOCR('img.png'))
|
||||
->tempDir('./my/custom/temp/dir')
|
||||
->run();
|
||||
```
|
||||
|
||||
### withoutTempFiles
|
||||
|
||||
Specify that `tesseract` should output the recognized text without writing to temporary files.
|
||||
The data is gathered from the standard output of `tesseract` instead.
|
||||
|
||||
```php
|
||||
echo (new TesseractOCR('img.png'))
|
||||
->withoutTempFiles()
|
||||
->run();
|
||||
```
|
||||
|
||||
### Other options
|
||||
|
||||
Any configuration option offered by Tesseract can be used like that:
|
||||
|
||||
```php
|
||||
echo (new TesseractOCR('img.png'))
|
||||
->config('config_var', 'value')
|
||||
->config('other_config_var', 'other value')
|
||||
->run();
|
||||
```
|
||||
|
||||
Or like that:
|
||||
|
||||
```php
|
||||
echo (new TesseractOCR('img.png'))
|
||||
->configVar('value')
|
||||
->otherConfigVar('other value')
|
||||
->run();
|
||||
```
|
||||
|
||||
__More info:__ <https://github.com/tesseract-ocr/tesseract/wiki/ControlParams>
|
||||
|
||||
### Thread-limit
|
||||
|
||||
Sometimes, it may be useful to limit the number of threads that tesseract is
|
||||
allowed to use (e.g. in [this case](https://github.com/tesseract-ocr/tesseract/issues/898)).
|
||||
Set the maxmium number of threads as param for the `run` function:
|
||||
|
||||
```php
|
||||
echo (new TesseractOCR('img.png'))
|
||||
->threadLimit(1)
|
||||
->run();
|
||||
```
