Prizm Content Connect Important Information
Note: You need to uninstall the prior version of PCC before installing a new version.
When installing Prizm Content Connect on Windows, the account used to start the Prizm service requires a password to be defined. Without a password the Installer will not be able to proceed.
The Windows installer will not allow you to install Prizm Content Connect x64 to the Program files folder on a 64-bit Windows system. If you select this folder for installation the installer will change the install location to be under the Program File (x86) folder.
Prizm Content Connect Known Issues
Known Issues for the HTML5 Client Viewer
There are limitations to using the Full Page Redactions mouse tool on a mobile device.
When requesting raster page content, a '500' error may appear in the network log. As part of performance improvements, the viewer now always requests SVG content first. If SVG content is not available, a '500' error will be communicated and the client will then request raster content. Although this does not negatively affect the viewer behavior, this will be changed in a future release to handle the request differently.
The Content Encryption feature is not supported in IE8.
When printing a document in Firefox or Safari, embedded images may be truncated or missing in some cases.
When printing a document in Chrome, images may be printed with a black background when the background should be transparent.
IE8 Documents are now searchable in PCC 8.0. However, there are cases where the initial search on a cold cache may fail but subsequent searches are successful.
PDF files with embedded raster images in the Indexed color space using CMYK palette might not display with the correct colors in the HTML5 viewer after conversion to SVG.
Search results returned in the HTML5 viewer for PDF documents may not be highlighted in cases where the PDF contains image over text results. In this case, content will be returned in the Search results tab, but the highlighted search terms will not be displayed in the page view when navigating to the appropriate page. In this case, a message will be displayed indicating that the page does not support text highlighting. This will be improved in future versions.
It is recommended that the document cache be cleared prior to upgrading PCC. Failure to clear the cache will result in the inability to search documents in the HTML5 viewer that have been cached in prior versions of PCC.
In some cases, very large documents (>500 pages) may not return all search result pages for a document. In this case, the warning icon will be displayed indicating that there are pages that could not be searched. In isolated cases, search results may be returned in the results pane but do not display a corresponding highlight in the page view. This can occur when there is a discrepancy between the extracted text and the SVG rendering of that text.
When printing documents with the HTML5 viewer in Safari browser on Windows, blank pages are sometimes created, causing extra pages in the document.
Known Issues for Text Annotations when Using IE9 in Standards/Native Mode:
After the text is entered to the edit box in the annotation object, the annotation object is still in the selected/edit mode and currently the lines will appear to be wrapping far too soon. It appears that only a 1/4 width of the rectangle is occupied. When a single-click is made, (outside the Text annotation object so that the annotation object is not in edit mode anymore), then at this point the lines will wrap at around 3/4 width of the bounding rectangle.
For certain bounding rectangle widths, (when resizing the width), the lines wrap just after single words.
If a word width is longer than the width of the bounding rectangle, then the word will bleed across the right edge of the rectangle. Wrapping within a single word with a dash is not implemented.
Known Issues for Prizm Services
The PCC RESTful API is no longer supported on CentOS 5.8.
Watermarks appear in bold and are not transparent.
The PCCIS "GET Page" call requesting a JPEG thumbnail for a certain page hosted on Windows might return HTTP error 500.
When the conversion of the source file reaches the timeout in the Prizm Service, the text search interface may not return all results from all pages. Note that the default conversion timeout is 10 minutes and can be extended by setting the values of http_response_timeout and worker_timeout in proxyserver_jar.properties.
The "extractattachments" REST API command creates a directory of the email attachments along with the additional temporary directories in the same location where the target is specified. The temporary directories contain body.rtf and body.txt and they remain after the "extractattachments" command is finished.
Write access to the Prizm\bin folder is required for working with e-mail message attachments.
Excel pagination is not currently supported for CSV files, causing incorrect page count.
Excel pagination causes the Office converter to generate more pages. This puts more stress on the server and may cause the conversion to timeout.
Prizm Content Connect running on Linux requires an X11 server to perform conversions for the HTML5 Viewer:
In order to convert some documents into PNG format used by the HTML5 Viewer, Prizm Content Connect on Linux requires an X11 server. If you have installed the product on a headless Linux server you will need to, at a minimum, run the X virtual framebuffer server to facilitate the conversions:
Install the X virtual framebuffer server.
Debian/Ubuntu:
# sudo apt-get install xvfb
Red Hat/CentOS:
# yum install xorg-x11-server-Xvfb
Start the X virtual framebuffer server. This must up and running any time the Prizm service is started.
# Xvfb :20 >/dev/null 2>&1 &
Export a DISPLAY environment variable for the Prizm Service to know where the X11 server is.
# export DISPLAY=:20
Start the proxyserver.
# /usr/share/prizm/scripts/proxyserver.sh start
Conversion of EMF and WMF files (to Raster or SWF files) produces files with a transparent background color instead of the expected solid background color.
When using the MSO Converter, the page count reported by the proxy-server and the viewers might mismatch the page count reported by MS Office and the viewers might fail to open the last page of the document.
Certain VML shapes from Word documents might not render properly to the client viewers.
E-mail attachments with non US-ASCII characters in their names are not supported.
E-mail messages attached to EML or MSG files are not supported.
Known Issues for the Proxy Server
Legacy PDF Watermarks: Text Watermarks show bold (not transparent) in the output PDF when added to PDF or Office documents.
CAD conversion to SVG: Vector Conversion Service adds geometry from the source CAD file to the output SVG. Since SVG is an XML-based vector image format for two-dimensional graphics, it does not support certain geometry like light sources, materials and etc. As a result, CAD chart with such elements will look like a "wired" model converted to SVG. In order to represent a CAD chart as a "solid" model, the HTML5 viewer should be configured for raster rendering. However, Vector Conversion Service uses OpenGL rendering for rasterizing CAD geometry, and the current support of OpenGL rendering within PCC is limited to Windows only.
Known Issues for the Legacy HTML5 Viewer
Legacy HTML5 and Flash JSP samples may not load and display EML files correctly.
Annotations created by the HTML5 viewer will be loaded into the wrong locations in the Flash viewer.
Text annotations scaling is off for annotations created in the Flash viewer and loaded in the HTML5 viewer.
Known Issues for the Deprecated Flash Viewer
When viewing certain PDF files in the Flash Viewer, the conversion process can search for system fonts to use when creating Flash-based content. This process of searching for system fonts can cause a performance degradation.
It's been noticed in some environments that SwfToolsShim.dll may be seen as a suspected risk by some anti-virus applications. This file ships as part of PCC and poses no risk. These warnings may be safely ignored.
