channels-methods (Package: pixmap) : Methods for Channel Manipulation

Functions for manipulation and extraction of colors from channel-based pixmap formats. Methods for generic addChannels adds the color channels of a colored pixmap and returns a grey version. Methods for generic getChannels return numeric matrices or arrays containing the specified channels.

pixmap-class (Package: pixmap) : Class Family "pixmap".

The family "pixmap" (“pixel maps”) of classes provides methods for creating, plotting and converting bitmapped images in currently three different formats: RGB ("pixmapRGB"), grey ("pixmapGrey")and indexed pixmaps ("pixmapIndexed").

addlogo-methods (Package: pixmap) : Methods for Adding a Pixmap Logo to a Plot

This method allows the addition of a re-scaled pixmap to an existing plot, possibly as a logo, optionally preserving aspect. It may be used interactively with locator, and is positioned in the coordinate system of the plot region. Since the logo is displayed using image, it does not yet seem possible to use the function outside this region.
