Bitonal and Color Image Processing
Document image processing and pre-recognition cleanup
Document Image Processing SDK Technology in the LEADTOOLS Document Imaging developer toolkit could help to improve document image readability and compression performance with the function of Image cleanup.
General image processing
LEADTOOLS provides over 200 image processing functions in several categories including document cleanup, medical image enhancement, color conversion and correction, noise reduction, edge detection and more. Combined with LEADTOOLS'150+ image formats, developers can build applications to handle virtually any imaging requirement in today's market.
Image segmentation
With LEADTOOLS, .NET, WinRT, WPF, C/C++ and web developers have several different ways to automatically and manually segment images that contain text and image regions. Image segmentation is important for improving OCR Recognition rates and compression efficiency within complex formats such as LEAD MRC, standard MRC T.44, and PDF. It is also useful in medical imaging for separating and identifying specific tissues, organs, and abnormalities.
Imaging common dialogs
LEADTOOLS Imaging Common Dialogs greatly simplify development and save hours of tedious programming. LEADTOOLS provides over 100 imaging common dialogs for features such as image processing, conversion and effects.
Image Display and Annotation
Image annotation and markup
Several LEADTOOLS SDKs include flexible and time tested image annotation technology for .NET, C/C++, Java and Web developers. LEADTOOLS image annotations are perfect for general image markup applications as well as specialized document and medical applications. Image annotations can be added to any Windows, .NET, iOS, OS X, Android, HTML5, Silverlight or WPF project.
Enhanced bitonal image display
LEADTOOLS provides advanced bitonal image scaling algorithms which improve the readability of bitonal, black and white images. Due to the lack of colors within the palette of 1-bit black and white images, they become splotchy and distorted when zoomed in or out. Therefore LEAD Technologies developed two options for improving the readability while maintaining the memory and speed advantages inherent to bitonal images.
Image display functions for .NET, C and C++; Image display controls for .NET and C++
With LEADTOOLS, developers can implement image viewers in any application with its comprehensive offering of image display controls for every major desktop, web, tablet and mobile platform. LEADTOOLS viewers include everything developers need from core features such as image display, interactive modes, thumbnails and touchscreen input to advanced display technology like HTML5, annotations, DICOM, 3D and more.
Image display controls for Silverlight and Windows Phone
Several LEADTOOLS SDK products include image viewers for Silverlight and Windows Phone applications. Silverlight viewers included are the LEADTOOLS Image Viewer, Image List, Image Pan Viewer, and Magnify Glass.
ASP.NET Web Form imaging controls
LEADTOOLS SDKs include several AJAX enabled ASP.NET Web Form controls for zero footprint imaging. These ASP.NET Web Forms controls encapsulate most LEADTOOLS features including image formats, image processing, document cleanup and more. LEADTOOLS Web Forms controls are cross-browser and cross-platform capable, giving applications the flexibility to run on Windows, Mac, Linux, iPhone, iPad, Android and more. Combined with LEADTOOLS WCF services or server-side scripts, web developers can create rich, yet lightweight applications with processor intensive features such like OCR.
WPF imaging controls
LEADTOOLS WPF Image Viewer controls support all Microsoft .NET BitmapSource image objects, and works directly with LEADTOOLS .NET classes to load more than 150 formats. LEADTOOLS fully styleable WPF Image Viewer control supports scroll, zoom, pan, magnify glass and image list.
Print images to Windows printers
LEADTOOLS can perform all of the image processing necessary to print directly to any Windows printer. LEAD has developed advanced image printing technology and high level programming interfaces that make it easy to add robust, extensible and fast printing features to any application. LEADTOOLS works in conjunction with Windows device contexts and Graphics objects to allow simple customization and complete control over printing processes.
Image Capture and Acquisition
Acquire images and control TWAIN devices and scanners
With LEADTOOLS you can control any scanner, digital camera or capture card that has a TWAIN (32 and 64 bit) device driver. High-level acquisition support is included for ease of use while low-level functionality is provided for flexibility and control in even the most demanding scanning applications.
Optimize scanning with LEADTOOLS Fast TWAIN acquisition
LEADTOOLS Fast TWAIN intelligently analyzes the TWAIN source, considering the requested bits per pixel, image type and compression, and finds the best compression type, transfer mode and buffering schemes to get the best performance possible.
Acquire images and control WIA devices and scanners
LEADTOOLS SDKs provides a powerful set of functions spanning the full spectrum of digital imaging, including in-depth support for image acquisition from Windows Image Acquisition (WIA) devices.
Capture images from the screen
LEADTOOLS provides functions for capturing all or part of the screen. The result can then be used with any of the LEADTOOLS image processing functions and can be saved in any of the 150+ image file formats that LEADTOOLS supports.
