Use LEADTOOLS OCR to Store Text from Screenshots to the Clipboard

Posted on 2020-01-20 11:18:45 by Nick Villalobos

Continuing off of my previous blog post about using LEADTOOLS OCR to save screenshots as searchable PDFs, this post demonstrates how to extract the text from those screenshots and store it back into your clipboard as plain text.

Like I said on the last blog post, developers can get images that have been copied to the clipboard using .NETs Clipboard Class. Instead of saving screenshots as searchable PDFs, this time we'll be using the GetText Method to retrieve text so we can store it back in the clipboard.

Faster Loading of Large Series in HTML5/JavaScript Medical Viewer

Posted on 2020-01-20 11:09:32 by Gabriel Smith

As we continue down the road from our recent LEADTOOLS Version 19 April Update, we are particularly excited about the enhancement we're going into more detail about today. As you might see from the title, our engineers were able to speed up the HTML5/JavaScript Medical Viewer.

No, this isn't one of those "it's faster" kind of announcements because we tested it on a new server or installed Google Fiber (technically, that's still under construction but we're kind of excited about that here in Charlotte, NC...back to my point!!!). This is a really big deal, and are talking about improvements of up to 5 - 12 times faster loading speeds! This update loads DICOM images over the web at nearly the same speed as a desktop application.

Do it in the Buffer: Introduction to Dithering

Posted on 2019-12-19 12:27:07 by Nick Villalobos

I recently became intrigued by some art work I saw online. It is a bunch of Rubik's cubes set up to reproduce a picture.

The artists are essentially reducing the image's colors down to a palette of six colors with dithering. By dithering the picture, it appears to look like the subject from a distance because the colors mix and merge to resemble the original colors. But the closer you get to the piece, the more it appears to be a bunch of randomly ordered colored squares. It sparked the artist in me, so I decided to use LEADTOOLS to help me come up with my own Rubik's Cubism-like art.
