LEADTOOLS Video Game Screen Capture & Upload to Youtube: Developer App Series

Posted on June 14, 2017 by Katie
Build Better Apps with LEADTOOLS

This post is part of our 2017 Developer App Series, which showcases apps created by our Support Agents over the course of eight weeks. These apps are intended to be larger, more thoughtful apps with highly practical purposes in mind, as opposed to a basic “how to” for a feature.

App Description

This app from Aaron will capture any window on the machine and continuously record that window to DVR. At any point in time, you can choose to save the full recording, a clip of the latest X number of seconds from the recording, or a screen shot of the window. There is also the ability to upload your saved video clip to YouTube for easy sharing.

Features Used

Instructions for Running the App

  1. Download the source code for this app from here
  2. Extract the contents to the C:\LEADTOOLS 19\Examples\Multimedia\ltmm\Dotnet\CS directory.
  3. Build csproj file with Visual Studio and run

Multithreaded Barcode Decoding with LEADTOOLS: Developer App Series

Build Better Apps with LEADTOOLS

This post is part of our 2017 Developer App Series, which showcases apps created by our Support Agents over the course of eight weeks. These apps are intended to be larger, more thoughtful apps with highly practical purposes in mind, as opposed to a basic “how to” for a feature.

App Description

This app uses the LEADTOOLS Barcode Engine alongside the LEADTOOLS Image Processing SDK to concurrently run different image processing algorithms in a multithreaded environment on a barcode image until the barcode can be found in one thread and cancel the others. This will help decode barcodes on particularly difficult images by doing 5 sets of image processing commands at the same time that are each optimized to find barcodes on commonly difficult images.

Do it in the Buffer: Introduction to Dithering

Posted on June 2, 2017 by Gabriel Smith

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.

This post is part of our 2017 Developer App Series, which showcases apps created by our Support Agents over the course of eight weeks. These apps are intended to be larger, more thoughtful apps with highly practical purposes in mind, as opposed to a basic “how to” for a feature.

App Description

This project from Mohamed will utilize the LEADTOOLS Multimedia DVR SDK alongside the Motion detector filter to capture a stream from a security or IP camera. When motion is detected in the camera, a convert control will save the previous 1 minute and the next 1 minute to a file for security purposes.

Do it in the Buffer: Comparison of RasterImage Image Data Access Methods in .NET

Posted on May 26, 2017 by Gabriel Smith

There are several ways to access the data in a RasterImage. If you need to get the RGB values of each pixel, then the GetPixel() and GetRow() methods are the simplest methods to use.

Few Pixels

If you need to get just one pixel, then GetPixel() is the easiest. GetPixel() works with image data of any bits per pixel and returns a RasterColor that includes the alpha channel information for 32 and 64 bit images. The sample below uses GetPixel()to fill the buffer with the entire image (not recommended—more on that below).
