Presentation Graphics and Multimedia
Presentation Graphics and Multimedia
This domain tests slide design, delivery controls and the elements of multimedia. Questions may cover slide masters, layouts, transitions, animations, timing, hyperlinks, image types, audio and video formats, compression and resolution.
Core rules
- A slide master controls consistent fonts, colours and placeholders across slides. A layout arranges placeholders on a slide.
- A transition is the effect between slides; an animation is an effect on an object within a slide.
- Timing can be manual or automatic. Speaker notes support the presenter but are not part of the projected slide by default.
- Raster images store pixels and can lose quality when enlarged; vector images use mathematical paths and scale cleanly.
- JPEG is good for photographs and uses lossy compression. PNG supports transparency and lossless graphics. GIF is limited in colour. MP3 is lossy audio; WAV is uncompressed audio.
Worked example
A school needs a sharp logo with a transparent background for slides. PNG is the better choice than JPEG because PNG preserves sharp edges and supports transparency. A photograph of the school building would be better as JPEG because its lossy compression reduces file size with acceptable quality for projection. The reasoning is based on image content: line art needs crisp edges, while photographs tolerate controlled loss.
Traps
Do not call a slide transition an animation. Linking a media file can fail if the file is moved; embedding stores it in the presentation. Changing a file extension does not change the actual format. High resolution increases file size, and missing fonts can change layout on another computer. Use media only when you have permission.
