PDF Reader with Text Extraction (Rasterization)

Atalasoft's PDF Reader with Text Extraction SDK allows Developers the ability to integrate PDF viewing, printing, and format conversion within an application.

PDF Reader with Text Extraction is an add-on to the DotImage SDK.

 

  • An add-on for our Imaging SDK that includes an engine for converting vector-based PDF documents into raster (pixel-based) images
  • Native PDF Viewing - View a PDF directly in a custom Windows or web application while embedding it outside of Adobe Reader
  • Conversion - Convert from PDF to another image format
  • If you're working with existing PDFs, you will need these controls

This SDK is needed if:

  • You have an already created PDF and want to view it using DotImage
  • You have created a PDF using DotImage and you want to view the PDF
  • You want to view / highlight searchable PDF’s.
  • If you are not sure, just ask!

PdfDecoder - Converts the PDF vector based programmatic image into a pixel based image for use with the AtalaImage object. To have PDF as an openable format using AtalaImage's constructor add a PdfDecoder to the static RegisteredDecoders.Decoders collection.

Supported PDF Reader Features:

Add high-speed viewing of PDF documents to your applications

  • Convert PDFs to raster images in the DotImage viewers without the Adobe Acrobat SDK
  • Print PDF documents using the DotImage printing components or by rendering onto a printer graphics object
  • Convert PDF documents into any supported DotImage image format (multipage TIFF, JPEG, etc).
  • Integrates with our web viewers for server-side viewing, panning, and zooming of PDF documents
  • Extract all images from a specified PDF page to their native bit depth
  • Specify a resolution to use when rasterizing the PDF for instant PDF thumbnails
  • Supports CCIT G3, G4, Flate, and JPEG embedded images
  • Support for PDF/A, JBIG2, and JPEG2000 compressed images
  • Supports PDF Specification versions 1.3, 1.4, 1.5, and 1.6

  • Supports all text rendering modes (full, stroke, clipping)
  • Supports tiling patterns and shadings
  • Supports all colorspaces: RGB, Gray, CMYK, ICCBased, Lab, Indexed, and Separation.

 

This SDK also allows you to search and highlight Searchable PDFs.  If you would like to create serachable PDF's using Atalasoft SDK's you would need our DotImage SDK, an OCR SDK, and our Searchable PDF SDK (PDF Translator) add-on to OCR.  If you also need to view and search / highlight after they are cretaed (or if you already have existing searchable PDFs) you would need our PDF Reader with Text Extraction SDK

Annotations: PDF, Burning, Custom

Twain Scanning

TWAIN is a scanning driver communication specification standard used for writing device drivers for scanner agnostic applications.

 

  • DotImage includes DotTwain, a library for interacting with scanners on a Windows machine
  • DotTwain adhers to the TWAIN standards for scanner and camera drivers.
  • Desktop Scanning - Configure and start a scan using DotTwain’s simple API
  • Custom Separation - Use barcodes or any other behavior to automatically divide and create individual documents from a bulk scan
  • Web Based Scanning (in browser) see WingScan under Products

Atalasoft DotTwain is a .NET SDK for capturing digital images from scanners, cameras, and other TWAIN devices. It uses the latest TWAIN specifications for ultra fast scanning.  DotTwain can be purchased as a stand alone SDK or is included within our DotImage SDK.  ISIS:  If you require ISIS scanning a seperate ISIS SDK is required.


DotTwain can be used in a small footprint web deployment delivered as a .NET "no-touch" or signed ActiveX. Or it can be used in a standalone .NET scanning solution. DotTwain supports 32- and 64-bit TWAIN 1.x/2.X drivers and is included in DotImage Document Imaging.

Acquisition

  • UI control that makes connection with twain scanners on the system
  • Allows user to select TWAIN scanner to use for capture
  • Provides an event interface to set properties and customize the capture process

Atalasoft is an Associate Memeber to TWAIN Working Group

www.inspectortwain.com is a database of scanner drivers and their compatability score with the TWAIN specification.

Features

  • Full context sensitive help and documentation.
  • Object-oriented design; a TWAIN extension to the .NET Framework.
Multipage Documents

Atalasoft's DotImage SDK gives you the ability to change pages in a document without loading them into memory.

 

  • DotImage includes a library for altering document structure in multipage PDF and TIFF files
  • DotImage can easily add, delete, or rearrange pages in a document with low memory consumption.
  • Simple methods to combine multiple documents into one document.

Multipage documents can be very large when fully loaded into pixel memory. To work with this, we provide:

These are useful for removing, rearranging, and adding pages to an existing document with minimal overhead.

  • PdfDocument
    • Combine static method for quick combining of PDF documents
    • PdfDocument.Pages collection contains PdfPage objects that allows pages to be added, removed and rearranged
    • PdfPage.Frame can be used with the PdfDecoder object to open the page into an AtalaImage.
  • TiffDocument
    • Combine static method for quick combining of Tiff documents
    • TiffDocument.Pages collection contains TiffPage objects that allows pages to be added, removed and rearranged
    • TiffPage.Frame can be used with the TiffDecoder object to open the page into an AtalaImage.
OMR Transformation

OMR or Optical Mark Recognition is commonly used to transform documents with marks into contextual data.


Typical uses include bubble sheet reading, reading form areas, and survey data extraction.

The process starts with alignment. During alignment a base template image is compared to a scanned image and it is lined up using landmarks on the document. Once this is complete the templates defined areas can be read from.

This format is included within DotImage

The following classes can be customized or used to create a custom OMR workflow:

  • DocumentAligner - Our base document aligner. Does the transformation to a document to match to a template. Can be replaced with custom code using IDocumentAligner.
  • DocumentRejector - Our base document rejector. Determines whether a document is matched or not. Can be replaced with custom code using IDocumentRejector.
  • OmrTemplateDocument - Used to define the template. Use code to define target areas and mark areas on a document. This will be used for matching and detecting marks.
  • OmrDocument - Used for the scanned multipage image to be compared to a template.
  • OmrPage - Represents a single scanned page.
  • OmrMark - The structured class to look at a mark area and what the determined result was.


 

Format Independence

The AtalaImage class is the representation of a single image in any image format. It uses ImageDecoders to load an image and ImageEncoders to save an image. ImageDecoder or Image Encoder can be extended to handle a special image file type. When using AtalaImage's constructor all ImageDecoders in the static RegisteredDecoders collection are used to open the file or stream.

Raster Image Manipulation

 

ImageCommand is the base class for doing a pixel operation on an image.

The most useful commands for document imaging are:

  • CropCommand - Convert image into a subset of its pixels
  • OverlayCommand - Put an image on top of another
  • ResampleCommand - resize an image
  • DynamicThresholdCommand - compress a document to black and white from color

Beyond these commands we also have libraries of additional commands broken down in to groups. Check out these namespaces for additional commands:

  • Atalasoft.Imaging.ImageProcessing.Channels - Commands to work with color images
  • Atalasoft.Imaging.ImageProcessing.Document - Commands optimized for textual scanned documents
  • Atalasoft.Imaging.ImageProcessing.Effects - Commands that alter pixel content
  • Atalasoft.Imaging.ImageProcessing.Fft
  • Atalasoft.Imaging.ImageProcessing.Filters - Commands that mimic photoshop commands
  • Atalasoft.Imaging.ImageProcessing.Transforms - Commands that alter pixel alignment

The DotImage SDK functions and engines can assist in converting an image into storable formats

  • Image Cleanup - Use our Imaging SDK’s functions to remove scanning artifacts, orient the page correctly, or remove noise that will interfere with the transformation process
  • Direct pixel access - Format and stream pixels into any engine to perform detection for the transformation process
