PHP Code

## Initialize an instance of OcrEngine

$ocr_engine = new OcrEngine();

\# Clear notifier list

$ocr_engine->clearNotifies();

\# Clear recognition blocks

$ocr_engine->getConfig()->clearRecognitionBlocks();

\# Add 2 rectangle blocks to user defined recognition blocks

$recognitionBlock = new RecognitionBlock();

$ocr_engine->getConfig()->addRecognitionBlock($recognitionBlock->createTextBlock(52, 48, 67, 74));

$ocr_engine->getConfig()->addRecognitionBlock($recognitionBlock->createTextBlock(100, 46, 38, 46));

\# Ignore everything else on the image other than the user defined recognition blocks

$ocr_engine->getConfig()->setDetectTextRegions(false);

\# Set Image property by loading an image from file path

$imageStream = new ImageStream();

$ocr_engine->setImage($imageStream->fromFile($dataDir . 'ocr.png'));

\# Run recognition process

if ($ocr_engine->process()) {

\# Retrieve an array of recognized text by parts

$text = $ocr_engine->getText()->getPartsInfo();

\# Iterate over the text parts

$i=0;

while ($i < sizeof($text)){

$info = $text[$i];

\# Display part information

print "Block: " . (string)$info->getBox() . " Text: " . (string)$info->getText().PHP_EOL;

$i+= 1;

}

}

I have tried phpOCR but it is not working. The script has two functions imagecreatefrompng and imagecreatefromjpeg which are not defined and hence gives an error.

This is a funny thing. Googling "php ocr image to text" brings this same question right on top of the results. So meta (or an oxymoron, if you prefer so)
