Document Imaging Features
LEADTOOLS Document Imaging toolkits build on LEADTOOLS' Raster Imaging technology to add performance-enhancing features specifically for black and white imaging. These include high-speed scanning, image clean-up, specialized bitonal (black and white) image display and processing, barcode recognition, OCR/ICR/OMR (character, handwriting, and form processing) recognition, comprehensive mark-up and annotation, output to 150+ file formats, and archival compression.
Key features that enable you to automate end-to-end document workflow include:
§ Special functions for Document (bitonal) images. The LEADTOOLS functions for bitonal images are especially useful for working with images from black-and-white scanners or FAX machines. These functions let you do things such as automatically straighten (deskew) an image, remove spots (despeckle), or clarify a scaled display (using scale-to-gray and favor-black features).
§ Annotation. LEADTOOLS supports annotation of images by letting you overlay images with text, lines, shapes, arrows, buttons, highlights, hot spots, sticky notes, stamps, buttons, and sounds.
§ Fast rotation. LEADTOOLS achieves fast rotation in 90-degree increments by applying a rotated view perspective to the bitmap.
§ FAST TWAIN support (32-bit). Analyze the TWAIN source, considering the bits per pixel, image type and compression requested from the TWAIN device, and find the fastest compression type, transfer mode and buffer schemes to get the best performance possible.
§ Faster compression and decompression. The LEADTOOLS functions for loading and saving are the same in all products. The only difference is in performance: the Document Imaging toolkits work faster when loading and saving LEAD CMP, JPEG, and CCITT Group 3 and Group 4 images.
§ 1-bit Image Clean-up. The Document toolkits include support for removing dots, blobs, holes, inverted text, lines, borders, bumps and nicks from 1-bit images.
§ Region Clean-up. Remove all the holes from a region.
§ Embedded Messages. The Document toolkits include support for embedding messages in lossless image formats like bmp, tiff, lossless jpeg, etc. The message is embedded without any visible changes to the image, and does not appreciably increase the size of the image. The message is password-protected.
§ 12 and 16 bit grayscale images. Load, process, display, window level and save 12 and 16 bit grayscale images (including support for 16-bit grayscale TIFF).
§ MRC Support. LEADTOOLS supports the Mixed Raster Content format for color documents containing mixed image and text components. For more information, refer to the MRC topics in the Getting Started with LEADTOOLS help file:
§ Raster PDF Save. Support for saving raster images as a PDF file. This includes the Advanced PDF save and compression features.
§ TWAIN scanning (16-bit grayscale and up to 48-bit color)
§ Scale to Gray 1-bit image display
§ Favor black display (preserves black objects when displaying zoomed-out 1-bit images)
§ 8–16-bit grayscale lossy and lossless JPEG compression
§ Read/Write compressed JBIG, JBIG2, LEAD CMW, JPEG 2000 (J2K, JP2, and JPX), and ABIC file formats
§ Super compressed 1-bit or 24-bit bitmaps (can be kept compressed in memory)
