MBITS(6) Games Manual MBITS(6) NAME mbits - macros to typeset bitmaps SYNOPSIS troff [ option ... ] -mbits [ option ... ] file ... DESCRIPTION These macros are used to typeset bitmaps. They are compatible with other troff macro packages, so that bitmap figures may be included in documents. .BM f Set the format for subsequent .BM requests to f. The de- fault is for blitblt(9.1) output. The other possibility is for faces and large icons in ASCII format. .BM f s Insert the bitmap from file f; each pixel will be s basic units square. The bitmap origin is placed at the current point, which is left unchanged. .BM f s dX dY Set the number registers dX and dY to the width and height (in basic units) of the bitmap in file f, assuming pixel size s. This form may be used to calculate posi- tioning. EXAMPLES This sequence centers the bitmap and spaces past it to continue with the text: .BM i .BM /n/face/48x48x1/pjw 6 dX dY .sp .in (\n(.lu-\n(dXu)/2u .BM /n/face/48x48x1/pjw 6 .in .sp \n(dYu FILES SEE ALSO blitblt(9.1), troff(1), bitfile(9.5), ms(6) BUGS At time of writing, mbits does not work with PostScript output devices. See mpictures(6) for an alternative. .BM does not work inside a diversion. The concept of `pixel size' varies among typesetting devices. MBITS(6)
