Source bitmaps specified with each <codeph>source</codeph> statement will be expected to exist in the directory specified with the latest <codeph>sourcepath</codeph> statement above it. </p> <p>Just a single colour-depth must be specified for all the source bitmaps within a single <codeph>source</codeph> statement, and must be of the form [<codeph>c</codeph>]<varname>digit</varname>,<varname>digit</varname>, where the optional <codeph>c</codeph> denotes whether the bitmap is a colour bitmap and the digits represent the colour-depth of the bitmap and the bitmap mask respectively. It is recommended that the mask has a colour depth of 1 bit per pixel, to minimise memory usage. </p> </conbody></concept>
