BLACKBOARD - ONLINE COURSES

Blackboard tools: compression tools

 

The speed at which you can load a document to Blackboard and at which your reader can download it from Blackboard is determined by its file size. Some files require compression to be usable. For example, Power Point file formats were designed for projection onto a large screen, so they are rather large, data rich files. When a Power Point presentation is viewed on a computer monitor, most of the data in the file is irrelevant, and simply slows the transmission process. These files need compression to be usable on a monitor. The situation is more or less the same for PDF files, depending on how they were initially created.

 

To compress Power Point files you can use PowerShrink 2008, which can be downloaded at www.powershrink.com. The trial version has 10 free uses, after which you will need to purchase the software.

 

To compress PDF files you can use PDF Compress 1.0, which can be downloaded at no cost here: www.bureausoft.com/products.html#PDF_Compress_(Freeware).
