(wccommon.mak [1.2]: 2000/03/10 08:15:31 lpd)	- The Windows zip archive didn't include font metrics files. (Thischange only fixes the build procedure: it doesn't actually update thecurrently released zip archive.)

(lib/gs_ttf.ps [1.3]: 2000/03/16 07:38:07 lpd) Adds a new example file, a 3-D synthetic image. (examples/doretree.ps [1.1]:2000/03/10 04:00:45 lpd) Adds implementations of the devforall, devstatus, and diskonlinecompatibility operators. (lib/gs_statd.ps [1.2]: 2000/03/10 04:01:55 lpd) Some Adobe CIDFonts include a line /Setup /cid_Setup load def thatapparently is intended only to prevent the fonts from being loaded by astandard PostScript interpreter (as opposed to ATM or a special fontloader), since cid_Setup is not defined anywhere and Setup is neverreferenced; this change adds a dummy definition of cid_Setup to work aroundthis. (lib/gs_cidfn.ps [1.3]: 2000/03/10 04:53:25 lpd) Updates the version # to 6.01, and the version date. (lib/gs_init.ps [1.2]:2000/03/10 17:18:29 lpd) Changes the default undercolor removal and black generation functions backfrom f(k) = k to f(k) = 0. This fixes some, but not all, of the reportedproblems with color inkjet output in 6.0. (lib/gs_init.ps [1.3]: 2000/03/1018:47:31 lpd) On Windows, puts stdout into binary mode as well as stdin, to allow pipingprinter output through stdout (not a good idea, but it should be supportedas well as on other platforms). (dwmainc.cpp [1.2]: 2000/03/17 06:22:59 lpd) </pre><h2><a name="6.01 Streams"></a>Streams</h2><pre> Changes the sbuf_min_left macro to a procedure for readability and inpreparation for later revision. (stream.c [1.2], stream.h [1.2]: 2000/03/1003:40:13 lpd) </pre><h2><a name="6.01 Library"></a>Library</h2><pre> Fixes problems:	- (%os%) currentdevparams didn't return (fixed) values forInitializeAction, Mounted, Removable, Searchable, SearchOrder, andWriteable, or (meaningful) values for BlockSize, Free, and LogicalSize.Currently, the latter values are dummies. (gsiodev.c [1.2]: 2000/03/1003:43:06 lpd)	- The terminating $ on the $Id: line in gsmalloc.c was missing, anddwuninst.rc lacked a $Id: line. (gsmalloc.c [1.2]: 2000/03/10 03:44:33 lpd)	- RasterOps with source transparency = 0, texture transparency = 1didn't match the (very peculiar) H-P specification even ifTRANSPARENCY_PER_H_P was defined. (gdevdrop.c [1.2], gdevmrop.h [1.2],gsropt.h [1.2]: 2000/03/10 04:06:15 lpd)	- The prototype for gs_exit() was not included even though gs_exit()was called. Fix: A cast discarded const unnecessarily. (gsalloc.c [1.2]:2000/03/10 04:08:23 lpd)	- The type of the %pipe% IODevice was /FileSystem, whereas it shouldbe /Special. (gdevpipe.c [1.2]: 2000/03/10 04:13:57 lpd)	- An incorrectly formatted procedure couldn't be converted correctlyby ansi2knr. (gxidata.c [1.2]: 2000/03/10 04:30:58 lpd)	- The check for a show within a cshow procedure for a CID font waswrong. Fix: Character widths in CIDFontType 0 fonts were ignored (!). Adds a.glyphwidth operator to support correct handling of character widths for CIDfonts. Adds a glyphwidth procedure to the library, like glyphshow andglyphpath, in order to support correct handling of widths for CID fonts.(gschar.c [1.2], gschar.h [1.2], gstext.c [1.2], gstext.h [1.2]: 2000/03/1004:41:47 lpd)	- The description of the value returned by code_map_decode_next in*pchr was incorrect. (documentation bug only) (gsfcmap.c [1.2]: 2000/03/1007:03:09 lpd)	- Fixes a problem producing too much black in the output; also addssupport for 5 new printers (H-P Color DeskJet 690, H-P DesignJet 750, andEpson Stylus Color 200). Note that this is user-contributed code.(gsargs.h [1.2]: 2000/03/16 02:01:36 lpd)	- The code for Axial shadings incorrectly assumed that if theshading axis was horizontal or vertical in user space, it was alsohorizontal or vertical in device space: this caused incorrect results whenthe CTM wasn't orthogonal. (gxshade1.c [1.2]: 2000/03/17 08:17:55 lpd)	- For printer devices, a non-null definition for OutputFile wasrequired even on platforms that had a default printer (as implemented bygp_open_printer for that platform). (gp.h [1.2], gsdevice.c [1.2]:2000/03/18 01:45:16 lpd) Clears the glyf and loca offsets in TrueType fonts that lack these tables,so that clients who care can tell whether the font is being downloadedincrementally. (gstype42.c [1.2]: 2000/03/10 03:45:29 lpd) Changes a few macro definitions to work around over-zealous compilerwarnings. (gstype1.c [1.2], gstype2.c [1.2], gxtype1.h [1.2]: 2000/03/1004:29:37 lpd) Changes the default undercolor removal and black generation functions backfrom f(k) = k to f(k) = 0. This fixes some, but not all, of the reportedproblems with color inkjet output in 6.0. (gxdcconv.c [1.2]: 2000/03/1018:47:31 lpd) </pre></body></html>
