2.90:Document Viewer (UI Element)

Graphic depicting the Grooper Document Viewer.

The Grooper Document viewer is the portal to your documents.

About

The Document Viewer allows users to view documents! It comes equipped with several different tools and settings that let you see what you need to see the way you need to see it. Like the Batch Viewer, there is no one place the Document Viewer exists. As you navigate through Grooper anytime there is some kind of interfact that needs you to view a document, or page, it will be present somwhere within the UI. These include, but are not limited to: general viewing of batch contents when using a Batch Viewer anywhere seeing the effects of an Image Processing Profile and using that visual feedback to make adjustments to said profile when writing regular expression patterns and viewing the highlighted results when testing extraction on any extractor, or even a full Data Model when reviewing information like Classification, or Extraction

Document Navigation and Rendition

Navigation ButtonsRendition Selector

Navigation Buttons

• Key in page number
• -> Go forward a page

Rendition Selector

This drop-down lets the user select which rendition of the file to display. For OCR’ed documents, you can choose between the image or the OCR text. For PDF documents that have been Recognized, you can view the PDF in its Native Format or its Character Data renditions. XML-Based Word and Excel Documents (.docx and .xslx files from Office 2007 onward) can be viewed their component XML files, where users can see versioning, formatting, style, application, workbook, sheet, and other information within the document.

Page View Tools

ScanOnce Adjustments

Changes the display format of the current page to color. Changes the display format of the current page to grayscale. Changes the display format of the current page to black and white. After applying one of the previous color space adjustments, this button will highlight and allow you to open a menu specific to that color adjustment to fine tune the change. This will remove any of the changes made from the previous buttons and revert the page back to its original state.
This is the menu mentioned in Step 4. This is an example of the tools available for the color and grayscale options. The black and white menu is slightly different in that it doesn’t provide sliders for adjustment, but instead a drop-down of choices for what style of thresholding you wish to apply.
Adjust the brightness and contrast of the image. Crop the image to a rectangular region. Inverts the polarity of the image. Adjust the gamma correction level of the image. Undo image adjustments. These adjustments have interface windows like the one seen in step 6.

Version Differences

Prior to Grooper 2.9 the Rendition Selector, and most of the image adjustment tools on pages did not exist.
