Reads an AutoCAD(Reg.) slide file and outputs a portable
pixmap. If no _s_l_i_d_e_f_i_l_e is specified, input is read from
standard input. The ppmdraw library is used to convert the
vector and polygon information in the slide file to a
pixmap; see the file ppmdraw.h for details on this package.
OOOOPPPPTTTTIIIIOOOONNNNSSSS
----aaaaddddjjjjuuuusssstttt
If the display on which the slide file was created had
non-square pixels, when the slide is processed with
ssssllllddddttttooooppppppppmmmm and the ----aaaaddddjjjjuuuusssstttt option is not present, the
following warning will appear:
Warning - pixels on source screen were non-square.
Specifying ----aaaaddddjjjjuuuusssstttt will correct image width to
compensate.
Specifying the ----aaaaddddjjjjuuuusssstttt option causes ssssllllddddttttooooppppppppmmmm to scale
the width of the image so that pixels in the resulting
portable pixmap are square (and hence circles appear as
true circles, not ellipses). The scaling is performed
in the vector domain, before scan converting the
objects. The results are, therefore, superior in
appearance to what you'd obtain were you to perform the
equivalent scaling with ppppnnnnmmmmssssccccaaaalllleeee after the bitmap had
been created.
----ddddiiiirrrr The input is assumed to be an AutoCAD slide library
file. A directory listing each slide in the library is
printed on standard error.
----hhhheeeeiiiigggghhhhtttt _s_i_z_e
Scales the image in the vector domain so it is _s_i_z_e
pixels in height. If no ----wwwwiiiiddddtttthhhh or ----xxxxssssiiiizzzzeeee option is
specified, the width will be adjusted to preserve the
pixel aspect ratio.
----iiiinnnnffffoooo
Dump the slide file header on standard error,
displaying the original screen size and aspect ratio
among other information.
----lllliiiibbbb _n_a_m_e
Extracts the slide with the given _n_a_m_e from the slide

library given as input. The specified _n_a_m_e is
converted to upper case.
----LLLLiiiibbbb _n_a_m_e
Extracts the slide with the given _n_a_m_e from the slide
library given as input. The _n_a_m_e is used exactly as
specified; it is not converted to upper case.
----ssssccccaaaalllleeee _s
Scales the image by factor _s, which may be any floating
point value greater than zero. Scaling is done after
aspect ratio adjustment, if any. Since scaling is
performed in the vector domain, before rasterisation,
the results look much better than running the output of
ssssllllddddttttooooppppppppmmmm through ppppnnnnmmmmssssccccaaaalllleeee.
----vvvveeeerrrrbbbboooosssseeee
Dumps the slide file header and lists every vector and
polygon in the file on standard error.
----wwwwiiiiddddtttthhhh _s_i_z_e
Scales the image in the vector domain so it is _s_i_z_e
pixels wide. If no ----hhhheeeeiiiigggghhhhtttt or ----yyyyssssiiiizzzzeeee option is
specified, the height will be adjusted to preserve the
pixel aspect ratio.
----xxxxssssiiiizzzzeeee _s_i_z_e
Scales the image in the vector domain so it is _s_i_z_e
pixels wide. If no ----hhhheeeeiiiigggghhhhtttt or ----yyyyssssiiiizzzzeeee option is
specified, the height will be adjusted to preserve the
pixel aspect ratio.
----yyyyssssiiiizzzzeeee _s_i_z_e
Scales the image in the vector domain so it is _s_i_z_e
pixels in height. If no ----wwwwiiiiddddtttthhhh or ----xxxxssssiiiizzzzeeee option is
specified, the width will be adjusted to preserve the
pixel aspect ratio.
All flags can be abbreviated to their shortest unique
prefix.
BBBBUUUUGGGGSSSS
Only Level 2 slides are converted. Level 1 format has been
obsolete since the advent of AutoCAD Release 9 in 1987, and
was not portable across machine architectures.
Slide library items with names containing 8 bit (such as
ISO) or 16 bit (Kanji, for example) characters may not be
found when chosen with the ----lllliiiibbbb option unless ssssllllddddttttooooppppppppmmmm has
been built with character set conversion functions
appropriate to the locale. You can always retrieve slides
from libraries regardless of the character set by using the

----LLLLiiiibbbb option and specifying the precise name of library
member. Use the ----ddddiiiirrrr option to list the slides in a library
if you're unsure of the exact name.
