<script src='.js/1.0.10/dist/tesseract.js'></script>

- 1 You need to pass an actual image to the recognize method, not just the reference to some file upload field. github./naptha/tesseract.js/blob/master/docs/image-format.md – C3roe Commented Aug 5, 2020 at 11:20
- Show the image as a text in the textarea or as image? – Edson Magombe Commented Aug 5, 2020 at 11:22
- @Edson Magombe I want to show the text from the image in TextArea – santosh Commented Aug 5, 2020 at 11:27

Reset to default 2If you attach an event listener to the file input, you can then recognize text once the file has been loaded successfully, like so:
<html>
<body>
<input type="file" id="myFile" name="filename">
<br><br>
<label><b>Your Converted Text:</b></label><br><br>
<textarea cols="30" name="original" rows="10" style="width: 100%;" id="convertedText">
</textarea>
<script src='https://cdn.rawgit./naptha/tesseract.js/1.0.10/dist/tesseract.js'></script>
<script>
var myFile = document.getElementById('myFile');
myFile.addEventListener('change', recognizeText);
async function recognizeText({ target: { files } }) {
Tesseract.recognize(files[0]).then(function(result) {
console.log("recognizeText: result.text:", result.text);
document.getElementById("convertedText").value = result.text;
});
}
</script>
</body>
</html>
