c# pdfsharp sample: How to type into a pdf form in reader SDK Library service wpf asp.net winforms dnn Linux-DeveloperGuide-PCCPlus1-part1345

Chapter 1

How Does the Viewer Work?

Prizm Content Connect uses a combination of Flex, Flash & AJAX technology to render the

documents. Here are steps which show in detail how the viewer works:

Step 1 – A request is sent from client browser for a document, including start page and

document viewing options

Step 2 – Server returns a swf file

Step 3 – Viewer loads on client side and makes an AJAX call for Fast Page Count

Step 4 – Viewer makes an AJAX call for Actual Total Page Count

Step 5 – Fast Page Count of document is calculated on server

Step 6 – Server returns Fast Page Count of Document

Step 7 – Total Page Count of document is calculated on server and returned asynchronously.

(Fast Page is calculated synchronously to reach step 8 quickly, and actual page count is returned

asynchronously)

Step 8 – Viewer makes an AJAX call for page n of the document

Step 9– Conversion File on the server gets the document name and page number and converts

page n in the document to swf file

Step 10 – Conversion File returns the generated swf file in a stream for viewer to display

Step 11 – Viewer makes an AJAX call for the next page of the document

proxyserver.jar - Prizm Proxy Service

Prizm proxy service is required for convert2swf utility to run. This service is installed and started

during the installation process.

convert2swf_proxy.properties contains the parameters and port information needed for

Prizm Proxy Service to run and is located in <installpath>/conf directory.

Starting the Proxy Server

Start the server using the following command

./<install>/scripts/proxyserver.sh start

You can also stop and check status of proxyserver using following commands

./<install>/scripts/proxyserver.sh stop

./<install>/scripts/proxyserver.sh status

To see the log files, check:

<install>/logs/proxyserver

log

You can also run proxyserver in a console

- run

<install>/scripts/proxyserver.sh console

to run the proxyserver in a console mode.

ViewerEnterprise.swf

ViewerEnterprise.swf is the Prizm Content Connect Plus navigation and viewer file containing the

UI code. ViewerEnterprise.swf basically acts as a wrapper viewing file and makes AJAX calls to

get the document pages in swf format. This file is used with convert2swf utility to produce the

resulting swf file with the navigation UI.

settingsenterprise.xml

settingsenterprise.xml file contains parameters used by the viewer. Updated the various

parameters based on your installation and machine configuration.

Parameter

Value

tempLocationURL

Webserver Link for above tempLocation

conversionFileURL

Exact url of the file which will take care of ajax calls and perform the

conversion

getTotalPagesURL

Exact url of the file which will return total pages of the document

getFastPagesURL

Exact url of the file which will return fast page count of the document

Example - settingsenterprise.xml file

<conversionFileURL>http://yourdomain/samplecode-enterprise/convertdocument.php</conversionFileURL>

<getTotalPagesURL>http://yourdomain/samplecode-

enterprise/gettotalpagecount.php</getTotalPagesURL>

<getFastPagesURL>http://yourdomain/samplecode-enterprise/getfastpagecount.php</getFastPagesURL>

</settings>

Document Conversion ProxyWebservice

Prizm has a built in HTTP & HTTPS WebServer which serves the document conversion requests

and does load balancing and various other tasks.

By default, after complete installation you can check if the Prizm HTTP WebServer is running by

typing in browser

http://localhost:18680/convert2swf

convert2swf Webservice by default is setup to run on port 18680 and in http mode.

Example 9:

To create a thumbnail of all pages of sample.doc:

java -jar convert2swfclient.jar source=sample.doc thumbnail=100x150

http://localhost:18680/convert2swf?

source=/var/www/html/samplecode/sample.doc&thumbnail=100x150

Example 10:

To create a thumbnail of page 6 of sample.doc, specify target location, and add watermark

“Approved” on each thumbnail:

http://localhost:18680/convert2swf?

source=/var/www/html/samplecode/sample.doc&wtmtext=Approved&wtmfont=Helvetica&wtmsi

&target=/usr/local/tempcache/

Setup proxy service on port other than 18680

Open <install_path>/conf/proxyserverconfiguration.config and change proxy_port

After changing the http_port, restart the proxyservice by using following commands
