Based on our ImageProcessing base component, ImageProcessing-CL, a command line application for image processing and image enhancement of PDF, TIFF, JPEG and PNG image files, is now available.

Features:

• Command line application.
• Multithreading / parallel processing ensures a high processing throughput
• Processes – PDF single files, lists of text files, folders and entire folder structures.
• Configuration via user interface.
• The selected functions, their parameters and processing sequence are managed via profiles.
• Several functions can be executed one after the other in a predefined order.
• Profile functions: new, copy, delete, rename, export to file, import from file.
• Option to process PDF scans / pages with image information only or all PDF pages.
• Loading a sample page and testing the image processing commands with a preview of the output and result files.
• The resolution, compression and quality parameters can be configured for PDF rendering.
• Logging.

    

Individual image processing functions:

• Detect and remove blank pages.
• Auto rotate pages
• Straighten pages
• Invert images (black to white)
• Remove black border
• Trim the edge
• Remove impurities
• Remove perforations
• Remove lines
• Convert color / grayscale to black / white </ a >

Features ImageProcessing-FM:

Image processing is used to improve and optimize the quality of scanned documents (PDF, TIFF, JPEG) or to improve the image quality for machine readability in preparation for a subsequent OCR recognition. This allows blank pages and black borders , Holes, lines and impurities are removed. The FM version is installed as a Windows service and can monitor one or more input folders.

• MS Windows service
• Multiple jobs can be created to monitor multiple input folders.
• Multithreading / parallel processing ensures a high processing throughput
• Configuration of the processing steps via profiles (new, copy, edit, delete, export, import)
• Only the start folder or the entire subfolder structure can be processed.
• Folder contents can be deleted after processing or the folder structure can be retained.
• The folder structure from the input folder can also be transferred to the target folder.
• File processing via filter – name, extension, created from / to, changed from / to.
• Sorted processing by name / date as well as ascending / descending possible.
• Generation of a new file name via variable (date, time, counter, original name / extension)
• Delete the original file (move), copy or create an archive copy
• Folder monitoring and processing start via file system events – immediately, or with an adjustable delay (0-999sec.), or over time interval (in min.)
• Start of processing at a set date / time with optional daily / weekly repetition.
• Adjustable number of retry attempts / time interval if a file should be blocked.
• Logging (all events, only the error events)

In order to be able to perform image processing functions in a PDF, the PDF must be “rendered”, i.e. be converted into an image. So far, 300dpi and JPEG or TIFFG4 were fixed as the resolution and compression. With the current version it is now possible to configure these parameters.

• Resolution for: color, grayscale, black & white
• Compression / Quality: Color / Grayscale – JPEG, JPEG2000, ZIP / Black & White: TIFFGr4, JBIG-2

Image Processing serves to improve and optimize the quality of scanned documents or to prepare for subsequent OCR processing in order to increase the recognition rate and readability. This also removes blank pages, black borders, perforations, lines and contaminants.

We have now developed our own components to integrate the functionality quickly and easily into our existing or new applications.

Image processing functions:

• Several functions can be carried out in a given order one after the other.
• Several functions can be carried out in a given order one after the other.
• The selected functions, their parameters and processing sequence are managed via profiles.
• Profile functions: New, Copy, Delete, Rename, Export to file, Import from file.
• Option to process PDF scans / pages only with image information or all PDF pages.
• Load a sample page and test the image processing commands with a preview of the source and result file.

Individual functions of image processing::

• Detect and remove blank pages.
• Rotate pages automatically
• Align pages
• Invert images (black to white)
• Remove black border
• Trim the border
• Remove impurities
• Remove perforations
• Remove lines
• Convert color / grayscale to black and white
