@@ -38,9 +38,46 @@ This module implements a Views Style plugin. It provides the following settings:
 
 1. Tile Source: A field that was added to the views list of fields with the image to be served. This should be a File or Image type field on a Media.
 2. Structured Text field: This lets you specify a file field   where OCR text with positional data, e.g., hOCR can be found.
+3. Structured Text Term: If your Islandora Object has a separate media with hOCR, point to it with this setting.
+4. File Width and Height fields: If you want to use TIFF or JP2 files directly, set the fields where the files' width and height can be found with these settings.
+
+### Media Attributes from IIIF Action
+
+The module also provides an action that lets a site owner populate a TIFF or JP2 image's width and
+height attributes into fields so the IIIF server is not bogged down trying to generate a manifest if
+it doesn't have them.
+
+It is a complex action that must be configured. Go to
+Admin -> Actions UI -> Actions, choose
+"Add image dimensions retrieved from the IIIF server" from the Create Action drop-down
+And on  the next screen, choose the width
+and height fields that the action should
+populate.
+
+To use it, either:
+- Add it as a derivative reaction to a node with an Original FIle as its child, or
+- Use it as a batch action, such as on a Paged Content object's list of child pages.
+
+### Setting up the action as a Context Reaction
+
+These instructions assume a standard Islandora Starter Site, so if you have different field names or Contexts, adjust accordingly.
+
+1. Go to admin/config/system/actions
+2. Choose "Add image dimensions retrieved from the IIIF server" from the Create Complex Action drop-down and then click Create.
+3. Enter Original File for the Source Media Use term.
+4. Choose media -- file -- Width and Media -- File -- Height for the corresponding configuration values and click Save.
+5. Go to admin/structure/context, and click Duplicate oon the Page Derivatives row.
+6. Name the new context something like "Retrieve Page Dimensionss". and edit it.
+7. This is the tricky bit, delete 'Original File' from the 'Media has term with URI' field and replace it with Service File. The explanation for this is that to retrieve a file from the IIIF server, it must be part of an Islandora Media that has been fully created and saved and given a URL. This hasn't happened yet when Original File derivatives are being created, so we need to hang our action onto a derivative that is created after the original one.
+8. Under Reactions, deselect the existing actions and select  "Add i mage dimensions from IIIF sserver" and click Save and continue.
+9. Go back to your Paged Content object and add another child with a File media, to which you should upload another TIFF or JP2 file.
+10. Without going  to the Original File Book Manifestt, make sure that a service file has been generated, then click Edit on the Original File media.
+11. Ensure that the Width and Height fields are populated with thee correct values from the file.
