Advanced hotspot settings in Easy PDF Search

Easy PDF Search now lets you share your index database with even more users and control access at a finer level with the Standard Edition license.

So say you’ve indexed tens of thousands of your PDF files.  Instead of each user in your company indexing the same files and having the same database on their machine, you can now share your index database with as many users as your hardware can support.

The Basic Edition license allows you to share your database with up to 2 remote users and has basic hotspot functionality.

The Standard Edition license lets you set up roles which controls access to your libraries:

and users which allows you to define different logins and assign roles to each user.

You can also set up a self-signed certificate to encrypt your connections using SSL for improved security.

If you’re concerned that your users may overload your machine with their search requests, you can define a limit to the number of result rows returned.

If this limit is reached when your users perform a search, a message so that they are aware that the search results have been truncated.

So if you need to share your index database with more than 2 users or require better control over security and access to your libraries, the Standard Edition license will meet those requirements.

Creating contact sheets in Easy DICOM Viewer

In Easy DICOM Viewer 5, you can now create contact sheets from images containing multiple slices/frames.

Say we have a series containing 94 slices.

We want to export all 94 images into a single PNG file.  When we choose the Export Image action, we select the Create contact sheet option.

Once exported, our PNG file looks like this:

You have full control over how the images are rendered.  You define how many columns to use, the size of each image, the background color, and the footer value.

What exactly is the footer value?  It’s whatever value you want displayed at the bottom of each image.  It can be static text, which isn’t very useful, or it can be one or more DICOM tag values.

For e.g. let’s say we want to display the slice location at the bottom of each image.  The tag we want is 0020, 1041.  We simply enter this value as the footer value e.g.

When we now export the PNG contact sheet, the slice location is displayed on the bottom of each thumbnail.

We could of course add some label to the value.  Say we add the label Location: to the value e.g.

resulting in this:

Anonymization options in Easy DICOM Viewer

Easy DICOM Viewer can be used to anonymize DICOM tag values in your DICOM files.  There are 3 options you can select:

Anonymize basic patient information

This option anonymizes the most basic DICOM tags, which are the following:

  • patient’s name (0010, 0010)
  • patient ID (0010, 0020)
  • patient birth date (0010, 0030)
  • patient’s age (0010, 1010)
  • patient’s sex (0010, 0040)
  • comment (0010, 4000)
  • institution name (0008, 0080)
  • institution address (0008, 0081)
  • institution department (0008, 1040)
  • Issuer of Patient ID (0010, 0021)
  • study description (0008, 1030)
  • series description (0008, 103E)
  • operator’s name (0008, 1070)
  • referring physician’s name (0008, 0090)
  • physician(s) of record (0008, 1048)

Anonymize top level tags using NEMA specification

This option anonymizes tags using the recommendations outlined in this link – http://dicom.nema.org/dicom/2013/output/chtml/part15/chapter_E.html#table_E.1-1.

Compared to the basic anonymization option above, this option anonymizes a lot more details.

Apply tags template

This option lets you apply a tags template to the selected images.  A tags template is a set of changes you want to apply to the DICOM tags.  You can create multiple templates for different purposes e.g. one template to modify certain tags to a specific value, another template to erase only patient details, and yet another tag to modify all patient, doctor and study details.

The Preview window will then show you how the tag values would appear in the modified images.

These 3 options give you complete flexibility as to how you want to anonymize the DICOM tags in your images.

Easy PDF Search ‘hotspot’

We added a ‘hotspot’ feature to Easy PDF Search to help you share your PDF index easily with other users.  We originally wanted to call it the ‘application server function’, but felt that ‘hotspot’ was a more user-friendly and recognisable name, and users would be familiar with the hotspot analogy on smartphones.

Setting up a hotspot

The hotspot function essentially shares your Easy PDF Search database with up to 2 other users.  When you set up a hotspot, you enter the port you want to open and the password.

Connecting to a hotspot

Once you have set up your hotspot, your users can connect to your hotspot using your computer name/IP address, port, and password.

Restrictions when searching a hotspot database

Your users can only search your existing index.  They will not be able to index any new files in your libraries.

This reduces the possibility of users indexing your PDF files unnecessarily.  For the user hosting the hotspot database, you can still index the new PDF files.

Let us know what you think of the hotspot feature, and any suggestions you may have.

The above feature area available in the Easy PDF Search Basic Edition.  For more advanced sharing options, you will require the Standard Edition.

You can download a 14-day trial of Easy PDF Search here, and experience for yourself how easy it is to search you PDF file collection, and share the index database with other users.

Scrolling to search words in Easy PDF Search

We had a user who contacted us recently with a navigation issue.  She had been using Easy PDF Search instead of Acrobat because Acrobat was too slow handling hundreds of pages.  However, because her PDF files are not in A4 format, it was cumbersome to scroll the pages using the scroll bars, to locate the search words.

We discovered that her PDF files were scans of historical publications, dating back to the mid-1850s, and were in the classic ‘broadsheet’ format.  This is a page at 50% magnification.

To read anything, you had to set the zoom to at least 200%.

To improve the usability for such files, we made the following changes in Easy PDF Search 7:

  • mouse panning
    Pressing the CONTROL key, together with the left mouse button, and moving the mouse allows you to pan the page left/right and up/down.  This removes the need to use the scroll bars.
  • scroll to next search word
    There is now a button you can click (or use the F3 key) to scroll the page to the next search word.


    You can limit the scope of this function by setting the 2 options to limit it to only the current word, and/or the current page.


    This removes the need to visually scan for the highlighted search words.

The user was amazed with these changes which helped her save even more time on a genealogical and historical research project.

Importing and exporting libraries in Easy PDF Search

in Easy PDF Search 6.5, we added the functionality  to export and import your category and library structure.  Some users wanted to share their library structures with other users, and there was no easy way to do that previously.

To export your library configuration settings, select the Export libraries configuration item from the Tools menu.

Then select a file to store the configuration in.  You can now share the file with another user.  To import the configuration, select the Import libraries configuration item from the Tools menu.

Then select the file you exported earlier.  Easy PDF Search will then import the category and library structure from the file.

Note that the existing library configuration will be replaced by this new configuration.

Searching the search results in Easy PDF Search

We recently had a user ask if it was possible to perform a search on the files returned by the search results in Easy PDF Search.  This isn’t possible for now.  There is however a workaround.

First, you need to copy the files returned by the initial search into another folder.  To do this, right click in the search results area to bring up the context menu, then select the Copy/move files to another folder… item.

In the subsequent window, enter the folder to copy the files to, then click on the Copy button.

Now we’ll need to create a library that references that folder.

Now all we need to do is select that library when we want to perform a search.

Patient status in Easy DICOM Viewer

Easy DICOM Viewer 4.7 lets you define statuses for each series of images.  A series can have an unread, reading, or completed status, as indicated by the colored circles.

In this way, you can easily identify images that require your attention.  You can easily filter the images in the patient history list by their status using the status filter:

You change the status of the series’ images when you open the series.  In the Patient information tab. select the status you want to apply to the series:
