If you have any questions or suggestions, you’re more than welcome to leave us a comment below. Hopefully one of the tools above has helped you extract text from your image. We will use the IronOcr.
In this tutorial, we will learn how to convert images to text in C and other.
Yes, some fonts are subjected to copyright, and you can get bitten by the law monster if you make money off edited images… Always check the usage license of the “free fonts”. There is a hidden nightmare behind fonts, and it is called copyright.
You can specify which font to use, but please do not go on a download frenzy and start using every font you find on the Internet. Just get all the images in the folder and loop through all of them. But before we wrap things up, here are a few more nuggets of information that you might be interested in.
For instance, the applications exists which convert the hardcopy of textbooks into pdf and word format. The task of reading text from images is not limited to invoices. This returns an array with 8 numbers, which are the coordinates of the text box. Define the ( x ,y ) position for the text and the value. Reading text from images Annotating text with correct labels. (C2) To calculate the dimensions of the text box, we have to use imagettfbbox(). Get the image width with imagesx() and height with imagesy(). If you want to be a happy person, just skip and use this as-it-is… If not, here’s how the calculations work: Yikes! This looks crazy, but the main bulk of this script is calculating the position of the text box. Imagettftext($img, $fontSize, $angle, $centerX, $centerY, $fontColor, $fontFile, $txt) $centerY = CEIL(($iHeight - $tHeight) / 2) $centerX = CEIL(($iWidth - $tWidth) / 2) $tHeight = max(, $tSize]) - min(, $tSize]) $tWidth = max(, $tSize]) - min(, $tSize]) $tSize = imagettfbbox($fontSize, $angle, $fontFile, $txt)
All you need to do is upload the image file to Google Drive first and open it with Google Docs.
$fontFile = "C:\Windows\Fonts\arial.ttf" // CHANGE TO YOUR OWN! Google Drive, Google Docs more specifically, has a little-known free OCR feature included for you. $img = imagecreatefromjpeg("balloon.jpg")
