-
Image Compression. Compress images using the best and fastest compression algorithms, such as JPEG, JPEG2000, CMP, CMW, ABC, LZW, G3/G4, Huffman, ABIC, MRC, JBIG, JBIG2, and run-length. LEADTOOLS offers comprehensive support for compression schemes found in standard raster file formats, as well as high-performance proprietary compression technologies that outperform the industry standards.
-
PDF and PDF/A. Load, save, convert and compress raster and text searchable PDF files. Convert to and from any supported format. Capture printer output to PDF. Save OCR results as text searchable PDF.
-
Image Display. Paint images and regions with transparency while controlling zoom, scale, fit, pan, scroll, brightness and contrast settings. LEADTOOLS can automatically reduce the colors based on the display device with dithering and palette control. Additionally, LEADTOOLS provides image-list and thumbnail browser controls, a user interactive magnifying-glass tool, as well as an automated pan-window.
-
Bitonal Scaling. Greatly enhance the on-screen quality and readability of resized black and white images using LEADTOOLS display options.
-
Annotation / Image Markup. Overlay images with a variety of annotation objects such as text, lines, shapes, arrows, buttons, highlights, hot spots, sticky notes, stamps and buttons in C, C++, .NET, WPF and Silverlight projects.
-
Image Processing. Use more than 200 digital filters and transforms to process images or regions of interest. Functions include deskew, smooth, sharpen, edge detect/enhance, modify brightness/contrast/gamma, change hue and saturation, red-eye removal, unsharp mask, add noise. Resize and rotate images using various resampling techniques including bicubic. Most image functions support both signed and unsigned images.
-
Document Cleanup. Automatically straighten (deskew) an image (including proprietary functions for deskewing scanned bank checks), remove noise (despeckle), and remove borders, hole punches, lines and inverted text. LEADTOOLS Document Imaging cleanup functions are especially useful when working with images from scanners or FAX machines.
-
Scanning (TWAIN / WIA). Control image acquisition from any TWAIN or WIA device including scanners and digital cameras. Use a device driver’s built in user-interface or create your own. Query a TWAIN source to determine TWAIN features the driver has implemented. The LEADTOOLS Fast TWAIN feature will automatically set the optimal settings to maximize scanning speed and performance.
-
Barcode. Detect, read and write 1D and 2D barcodes within an image.
-
OCR / ICR. Add multi-threaded OCR to projects and utilize multiple cores to maximize performance. Convert images of text (machine print or hand written) in Latin, Asian, Arabic and MICR character sets. Output results as several supported formats including text searchable PDF, DOC and HTML to disk or memory.
-
OMR. Process checkboxes and bubble sheets in forms, ballots, surveys and tests.
-
Forms Recognition and Processing. Automatically recognize images as a specific form and then pull data from predefined fields.
-
Document Writers. Convert printer output and EMF to a variety of document formats such as PDF, DOC, HTML, XPS, RTF and text.
-
Virtual Printer. Capture output with LEADTOOLS advanced and programmable virtual printer driver.
-
Printing. Print images or regions of interest while controlling position, scaling, half-toning and dithering. Print multiple images and text to a single or multiple pages.
-
Common Dialogs. LEADTOOLS imaging common dialogs combine Windows Common Dialog functionality with LEADTOOLS imaging functionality. Common dialogs are provided for every LEADTOOLS image processing function, plus additional functions such as FileOpen and FileSave. All strings can be customized or localized for globalization.
-
Medical Image Viewer Control. Use the Medical Image Viewer Control to provide support for the display and manipulation of one or more medical images.
-
3D. Create 3D volumes from 2D slices and then render them on the screen using a variety of rendering methods and tools to improve visualization including MPR, VRT, MIP, MinIP and SSD. Viewing options include planes, clip, slab, scale, zoom, threshold, image processing, and full camera control.
-
12 and 16 bit grayscale images. Load, process, display, window level and save 12 and 16 bit grayscale images including DICOM and TIFF formats.
-
Window leveling. Detect and set LowBit and HighBit for image data, display images with automatic LUT intensity expansion, or set LUT entries and ranges with specific values and gradients. Display images through the LUT without changing the data, or process the image data using the LUT. Linearize the number of pixels locally in a bitmap, based on the specified color space in order to bring out the detail in dark areas of an image, and smooth the edges between blocks.
