### 40.3 Specifying custom settings for individual graphics

Many of the graphics settings you can specify in the configuration file apply to all the graphics in your document. However, if the right setting for one graphic is wrong for another, you might be able to override the configuration value for an individual graphic, with a PI marker.

You can use PI markers to insert configuration overrides in your DITA document. For RTF output, use a Config or RTFConfig PI marker for this purpose; for HTML output, a Config or HTMConfig PI marker. See §42.2.2 Overriding settings with configuration PI markers. The following tables show which settings can be overridden:

Table 42-2 Fixed-key configuration sections subject to overrides

Table 42-6 HTML graphic sections subject to overrides

Fixed-key overrides persist until the end of the file, or until changed by another override; variable-key overrides apply only to the next graphic (see §42.2.7 Understanding fixed-key vs. variable-key settings).

See also:To override a setting for a given graphic, place the marker just before the <image> tag. For marker text, supply the setting you want to change.
