HTML Export - Page 2
Determines the type of publication.
You can specify if you want to include frames, create a title, or display presentation notes.
Defines the basic settings for the intended export.
Standard HTML format
Creates standard HTML pages from export pages.
Standard HTML with frames
Creates standard HTML pages with frames. The exported page will be placed in the main frame, and the frame to the left will display a table of contents in the form of hyperlinks.
ماۋزۇ بەت قۇر
Creates a title page for your document.
Specifies that your notes are also displayed.
Creates a default HTML presentation as a kiosk export, in which the slides are automatically advanced after a specified amount of time.
As stated in document
The slide transition depends on the timing that you set for each slide in the presentation. If you set a manual page transition, the HTML presentation introduces a new page by pressing any key from your keyboard.
The page transition takes place automatically after the specified period of time elapses and does not depend on the presentation's contents.
Slide view time
Defines the amount of time for each slide display.
Automatically restarts the HTML presentation after the last slide has been displayed.
In a WebCast export, automatic scripts will be generated with Perl or ASP support. This enables the speaker (for example, a speaker in a telephone conference using a slide show on the Internet) to change the slides in the audience's web browsers. You will find more information on WebCast later in this section.
Active Server Pages (ASP)
When you select the ASP option, the WebCast export creates ASP pages. Note that the HTML presentation can only be offered by a web server supporting ASP.
Used by WebCast export to create HTML pages and Perl scripts.
URL for listeners
Specifies the URL (absolute or relative) to be entered by the viewer in order to see the presentation.
URL for presentation
Specifies the URL (absolute or relative), where the created HTML presentation on the web server has been saved.
URL for Perl scripts
Specifies the URL (absolute or relative) for the generated Perl scripts.
More Information on WebCast Export
There are two possible options for exporting LibreOffice Impress presentations using WebCast technology: Active Server Pages (ASP) and Perl.
In either case, the WebCast needs an HTTP server offering either Perl or ASP as scripting. Therefore, the exporting option depends on the HTTP server used.
WebCast in ASP
To export to ASP, in a LibreOffice Impress document choose File - Export. You then see the Export dialog in which you select HTML Document as the file type. Once you have selected a directory and entered a file name, click Export. For export as ASP, we recommend selecting a "secret" file name for the HTML file (see below for more details). You then see the HTML Export dialog. Several files will be written to the directory you have just selected.
The presenter uses the entered file name to change between the slides viewed by the audience. You can save the WebCast files locally or save them directly to an HTTP server. You can later transfer locally saved files to the HTTP server by FTP. Note that WebCast only works if the files are requested over an HTTP server.
Do not use the same directory for two different HTML exports.
Select WebCast as a publishing type on the second page of the HTML Export Wizard.
In the options area for WebCast, select the Active Server Pages (ASP) option. You can now continue defining other settings or start the export by clicking the Create button.
Using ASP WebCast
You can use WebCast as soon as the exported files can be accessed from an HTTP server.
Let's assume that you installed the Microsoft Internet Information Server on your computer. You entered the "c:\Inet\wwwroot\presentation" directory as an HTML output directory during the IIS setup. The URL of your computer is assumed as follows: "http://myserver.com".
The audience can now view the slide selected by the presenter through the URL http://myserver.com/presentation/webcast.asp. They cannot move to other slides found at this URL, unless the file names are known. Please ensure that the HTTP server does not show the directory listing.
WebCast over Perl
To export, in a LibreOffice Impress document choose File - Export. This opens the Export dialog, in which you select HTML Document as the file type. After selecting a folder and entering a file name, click Save. This opens the HTML Export Wizard. This will write some files to the folder you have just selected.
The entered file name will be used by the presenter to switch through the slides. Please select an empty directory.
In the second page of the HTML Export, select WebCast as the publication type.
In the option area for WebCast, select Perl.
In the URL for listeners text box, enter the file name of the HTML document that will be used by the audience. In URL for presentation, enter the URL of the directory that will be used for the presentation and, in URL for Perl scripts, enter the URL for the CGI script directory. You can now define further settings on the following pages of the Wizard or start the export process by clicking the Create button.
Using Perl WebCast
The files that have been created during the export must now be set up in the Perl enabled HTTP server. This cannot be done automatically because of the variety of different HTTP servers having Perl support. The steps to follow will be described next. Please refer to your server manual or ask your network administrator how to apply these steps on your server.
You should first move the files that have been created during the export into the correct directory on the HTTP server.
Move all files having the htm, jpg and gif extensions into the directory on your HTTP server that has been referred to in the text box URL for presentation.
All files having the pl and txt extensions have to be moved into the directory on your HTTP server that has been referred to in the URL for Perl scripts text box. This directory has to be configured in a way that the Perl scripts contained there can also be run by an HTTP request.
On UNIX systems grant the files with the pl extension the rights to be executable by the HTTP server. Normally, this is done with the chmod command. The rights of the currpic.txt file must be set to be writable by the HTTP server.
Now you should be able to use WebCast.
In this example, you have a Linux computer with an HTTP server. The URL of your HTTP server is http://myserver.com and the output directory of your HTML documents is the //user/local/http/ directory. Your Perl scripts are contained in the //user/local/http/cgi-bin/ directory. Enter secret.htm as an export file name and presentation.htm as URL for listeners. In the URL for presentation text box enter http://myserver.com/presentation/ and for the URL for Perl scripts enter http://myserver.com/cgi-bin/.
Now, copy all *.htm, *.jpg and *.gif files from the directories that were specified during the export into the //user/local/http/presentation/ directory on your HTTP Server and copy all files with the *.pl and *.txt extensions into the //user/local/http/cgi-bin/ directory.
Login on your server as root and switch to the //user/local/http/cgi-bin/ directory. You can define the corresponding rights using the chmod command.
Once you have finished installing the Perl files, the presenter will be able to give the presentation. The listeners can view this presentation under the URL http://myserver.com/presentation/presentation.htm.
