xbmview.sda is an XBM (X Bitmap) viewer for the 64. I have released
it as freeware.

X bitmaps are actually small C constructs designed to be included in
C programs. As such, they are plaintext and therefore quite
inefficient for large images. However, they are commonly used for
small clip images, and since they are plaintext can easily be included
in 7-bit worlds like E-mail messages and Usenet. Furthermore, virtually
all graphical web browsers understand it, including Netscape, Internet
Explorer and even Mosaic to its very earliest version.

xbmview.sda auto-dissolves when you RUN it into XBMVIEW and three
sample images: BACK.XBM (a back arrow icon), BINARY.XBM (a binary file
icon stolen from Gopher), and LETNUM.XBM (a letters and numbers
example with a familiar font :-) generated with my genxbm utility).
xbmview expects the .xbm files to be in *true ASCII* -- do not convert
them to PET ASCII -- and requires the _height and _width defines to
precede the array of unsigned char (if this makes no sense, don't worry
about it). It is fairly lax about syntax, however: things that gcc
would object strenuously to, will probably parse just fine if the data
is there. :-)

Because of the way xbmview is written, it is limited to images under
256x200 in size (which should not be a problem anyway). It does not
yet handle colour images -- you will probably get some weird results of
you try. :-)
