In some cases, it is possible to use images of text for visualisation, for instance where a particular presentation of text is essential to provide the information, for instance type samples, logotypes, branding, charts, screenshots and diagrams, etc. Images of text may also be used in order to use a particular font that is either not widely deployed or which the author doesn’t have the right to redistribute (W3C, n.d.).
Below is an example of “images of text” and “common text”.
- text in a particular font size
- foreground and background colour
- font family
- line spacing or alignment to be able to receive the information from the image
