If no slidefile is specified,\ninput is read from standard input. The ppmdraw library is used to convert the vector and\npolygon information in the slide file to a pixmap; see the file ppmdraw.h for details on this\npackage.\n\n### OPTIONS\n\n#### -adjust\n\nIf the display on which the slide file was created had non-square pixels, when the\nslide is processed with sldtoppm and the -adjust option is not present, the following\nwarning will appear:\nWarning - pixels on source screen were non-square.\nSpecifying -adjust will correct image width to compensate.\nSpecifying the -adjust option causes sldtoppm to scale the width of the image so that\npixels in the resulting portable pixmap are square (and hence circles appear as true\ncircles, not ellipses). The scaling is performed in the vector domain, before scan\nconverting the objects. The results are, therefore, superior in appearance to what\nyou'd obtain were you to perform the equivalent scaling with pnmscale after the bitmap\nhad been created.\n\n#### -dir\n\nslide in the library is printed on standard error.\n\n#### -height\n\nScales the image in the vector domain so it is size pixels in height. If no -width or\n-xsize option is specified, the width will be adjusted to preserve the pixel aspect\nratio.\n\n#### -info\n\naspect ratio among other information.\n\n#### -lib\n\nExtracts the slide with the given name from the slide library given as input. The\nspecified name is converted to upper case.\n\n#### -Lib\n\nExtracts the slide with the given name from the slide library given as input. The\nname is used exactly as specified; it is not converted to upper case.\n\n#### -scale\n\nScales the image by factor s, which may be any floating point value greater than zero.\nScaling is done after aspect ratio adjustment, if any. Since scaling is performed in\nthe vector domain, before rasterisation, the results look much better than running the\noutput of sldtoppm through pnmscale.\n\n#### -verbose\n\nDumps the slide file header and lists every vector and polygon in the file on standard\nerror.\n\n#### -width\n\nScales the image in the vector domain so it is size pixels wide. If no -height or\n-ysize option is specified, the height will be adjusted to preserve the pixel aspect\nratio.\n\n#### -xsize\n\nScales the image in the vector domain so it is size pixels wide. If no -height or\n-ysize option is specified, the height will be adjusted to preserve the pixel aspect\nratio.\n\n#### -ysize\n\nScales the image in the vector domain so it is size pixels in height. If no -width or\n-xsize option is specified, the width will be adjusted to preserve the pixel aspect\nratio.\n\nAll flags can be abbreviated to their shortest unique prefix.\n\n### BUGS\n\nOnly Level 2 slides are converted. Level 1 format has been obsolete since the advent of Au‐\ntoCAD Release 9 in 1987, and was not portable across machine architectures.\n\nSlide library items with names containing 8 bit (such as ISO) or 16 bit (Kanji, for example)\ncharacters may not be found when chosen with the -lib option unless sldtoppm has been built\nwith character set conversion functions appropriate to the locale. You can always retrieve\nslides from libraries regardless of the character set by using the -Lib option and specifying\nthe precise name of library member. Use the -dir option to list the slides in a library if\nyou're unsure of the exact name.\n\n### SEE ALSO\n\nAutoCAD Reference Manual: Slide File Format, pnmscale(1), ppm(5)\n\n### AUTHOR\n\nJohn Walker\nAutodesk SA\nAvenue des Champs-Montants 14b\nCH-2074 MARIN\nSuisse/Schweiz/Svizzera/Svizra/Switzerland\nUsenet: kelvin@Autodesk.com\nFax: 038/33 88 15\nVoice: 038/33 76 33\n\nPermission to use, copy, modify, and distribute this software and its documentation for any\npurpose and without fee is hereby granted, without any conditions or restrictions.
