iText for mac special edition function introduction
Easy selection of images
iText supports multiple ways to select images, and the operation is very convenient.
Capture screen
iText built-in screen capture tool. Just press the shortcut key ⇧⌘1, capture any area on the screen, and then extract the text. Tip: The recognized text has been copied to the system clipboard. You can paste it directly.
Drag the image to the menu bar icon
For example, when you see an image in Twitter and want to extract the text or numbers inside, just drag the image to the menu bar icon of iText, and you can get the content you want.
Select image file
Of course, you can also select the picture file to be recognized. However, in this case, the aforementioned dragging is preferable.
Continued recognition
For example, take screenshots of different locations in the PDF, iText will recognize the text in turn and automatically connect the results.
Powered by Google
First of all, I excluded the offline recognition library because the offline library is dead and cannot improve itself. Next, among many online OCR services, I compared products such as Microsoft and Google. Finally, I chose Google's service because it is very powerful and can recognize more than 50 languages.
-For ordinary natural languages, such as book pages, press releases, the recognition results are very accurate, even as high as 100%.
-For complex typesetting, especially for special characters (for example, program source code), the recognition result is not so good, you may need to manually modify the result after recognition.
-For example, for a vertical line, the machine cannot distinguish between lowercase l or uppercase I (by the way, can you recognize them?); instead, the machine needs to understand the context to optimize the result. But now it is difficult for machines to understand non-natural languages such as program source code.
Optimize recognition results
The OCR service can accurately recognize the text in the image, but it cannot be used for further recognition, such as paragraph recognition.
Therefore, iText includes its own algorithm to optimize the results, for example,
-Automatically recognize paragraphs.
-Remove extra spaces between English words and punctuation.
-Capitalize the first letter of English.
Preview the original image for proofreading
Since current OCR technology cannot always recognize text 100%, it is necessary to check the original image to modify the result. In iText, you can:
-Drag the result window near the image.
-Display the image on the left side of the result window.
Automatic translation
After recognizing the text in the image, iText can automatically translate them into more than 100 languages, supported by Google.
