Testing PowerPoint Slide Viewers

This is a Microsoft Skydrive embed

Note that this presentation can be expanded to fullscreen by clicking the icon in the righthand lower corner. The setup time is slower than the other viewrs but after the response time is quite good. Finally unlike the Google Docs empowered embed below – there is no limit to the the presentation size.

This is a Slideshare.net embed

This presentation on Slideshare matches almost all of the features of the Skydrive version except the online editing. It is faster on load but must be public on the Slideshare site for anybody to use and see.

This is a PowerPoin file in YGN Viewer

Note the problem – the YGN viewer refuse to show the same presentation that Skydrive and Slideshre bothe easily handle. It appears that presentations larger than about 2-4MB [it varies perversely], refuse to show in the Google Doc powered embeds.

A smaller file in Google Documents Embedded viewer

[gview file=”http://imagenation.theopensourcery.com/freephotoedit2007a.pptx” profile=’3′ width=’100%’  height=”600″ save=”0″][/gview]

The results will be nearly identically the same because the underlying viewer for the YGN and Google Document Viewer are the same – Google Docs engine. Both fail to display Powerpoint 2003.PPT files with greater than about 20 slides or 2-4MB in size. The YGN viewer provides better default height and line up of the slide pages both initially and as you advance through the pages.

The Google Document Embedded viewer provides  a number of system wide settings and a wealth of options for controlling the viewer for end users as shown below:

file= (required) The fully qualified URL pointing to the file you wish to embed. If many of your files start with the same root directory, you can set a File Base URL in your viewer profile and only enter the unique part of the filename here instead of the full URL.
width= (optional) Enter a number (in px) or a percent value to override the program’s default document width.
height= (optional) Enter a number (in px) or a percent value to override the profile’s default document height. Because of the way CSS works, you probably want to enter a pixel value here as a percentage may not function as you expect.
page= (optional) Specify a page number to begin viewing the embedded document.
profile= (optional) Enter the profile ID or name from the profile list for the settings you want to use for the document. If none is specified, the default profile is used.
save= (optional) Enter a value (1 to show, 0 to hide) to override the default display setting for the download link. Note that this setting is ignored on private documents.
cache= (optional) Add cache="0" to disable integrated document caching (useful only for frequently overwritten files).
authonly= (deprecated) Add authonly="1" to only show the download link to logged-in users on an individual file. This feature will be removed in a future version as it is now redundant; please set your download link preferences in your viewer profiles instead.
lang= (deprecated) Enter a supported language’s ISO 639-1 Language Code to override the global Default Language setting. This feature will be removed in a future version as it is now redundant; please set your language preferences in your viewer profiles instead.

So if further testing shows the GDE viewer to be as reliable as the YGN viewer in displaying  Adobe PDF and PowerPoint files I will convert exclusively to GDE. But it is disconcerting to see so many different .PPT files which display flawlessly on the PC not work in these Web-based PPT viewers.
