- * We sort the colormap by closeness and try to allocate the color

- * Either the colormap must have changed (since the last close color
- * allocation or possibly while we were sorting the colormap), or the
- * color is allocated as Read/Write by some other client. (Note: X
- * _should_ allow clients to check if a particular color is Read/Write,
- * but it doesn't! :-( ). We cannot determine which of these scenarios
- * occurred, so we try the next closest color, and so on, until no more
- * colors are within closeness of the target. If we knew that the
- * colormap had changed, we could skip this sequence.
- *
- * If _none_ of the colors within closeness of the target can be allocated,
- * then we can finally be pretty sure that the colormap has actually
- * changed. In this case we try to allocate the original color (again),
- * then try the closecolor stuff (again)...
- *
- * In theory it would be possible for an infinite loop to occur if another
- * process kept changing the colormap every time we sorted it, so we set
- * a maximum on the number of iterations. After this many tries, we use
- * XGrabServer() to ensure that the colormap remains unchanged.
- *
- * This approach gives particularly bad worst case performance - as many as
- * <MaximumIterations> colormap reads and sorts may be needed, and as
- * many as <MaximumIterations> * <ColormapSize> attempted allocations
- * may fail. On an 8-bit system, this means as many as 3 colormap reads,
- * 3 sorts and 768 failed allocations per execution of this code!
- * Luckily, my experiments show that in general use in a typical 8-bit
- * color environment only about 1 in every 10000 allocations fails to
- * succeed in the fastest possible time. So virtually every time what
- * actually happens is a single sort followed by a successful allocate.
- * The very first allocation also costs a colormap read, but no further
- * reads are usually necessary.

+ * allocation or possibly while we were sorting the colormap), or the
+ * color is allocated as Read/Write by some other client. (Note: X
+ * _should_ allow clients to check if a particular color is Read/Write,
+ * but it doesn't! :-( ). We cannot determine which of these scenarios
+ * occurred, so we try the next closest color, and so on, until no more
+ * colors are within closeness of the target. If we knew that the
+ * colormap had changed, we could skip this sequence.
+ *
+ * If _none_ of the colors within closeness of the target can be allocated,
+ * then we can finally be pretty sure that the colormap has actually
+ * changed. In this case we try to allocate the original color (again),
+ * then try the closecolor stuff (again)...
+ *
+ * In theory it would be possible for an infinite loop to occur if another
+ * process kept changing the colormap every time we sorted it, so we set
+ * a maximum on the number of iterations. After this many tries, we use
+ * XGrabServer() to ensure that the colormap remains unchanged.
+ *
+ * This approach gives particularly bad worst case performance - as many as
+ * <MaximumIterations> colormap reads and sorts may be needed, and as
+ * many as <MaximumIterations> * <ColormapSize> attempted allocations
+ * may fail. On an 8-bit system, this means as many as 3 colormap reads,
+ * 3 sorts and 768 failed allocations per execution of this code!
+ * Luckily, my experiments show that in general use in a typical 8-bit
+ * color environment only about 1 in every 10000 allocations fails to
+ * succeed in the fastest possible time. So virtually every time what
+ * actually happens is a single sort followed by a successful allocate.
+ * The very first allocation also costs a colormap read, but no further

-.SH DESCRIPTION
-.PP
-The \fIsxpm\fP program can be used to view any XPM (version 1, 2, or 3) file
-and/or to convert a file from XPM1 or XPM2 to XPM version 3. If \fIsxpm\fP is
-run with any dummy option specified, the usage is displayed. If no geometry is
-specified, the show window will have the size of the read pixmap. Pressing the
-key Q in the window will quit the program.
-.SH OPTIONS
-.TP 8
-.B \-d \fIdisplay\fP
-Specifies the display to connect to.
-.TP 8
-.B \-g \fIgeom\fP
-Window geometry (default is pixmap's size).
-.TP 8
-.B \-hints
-Set ResizeInc for window.
-.TP 8
-.B \-icon \fIfilename\fP
-Set icon to pixmap created from the file \fIfilename\fP.
-.TP 8
-.B \-plaid
-Show the plaid pixmap which is stored as data\fP.
-.TP 8
-.B \fIfilename\fP
-Read from the file \fIfilename\fP and from standard input if \fIfilename\fP is '-'.
-If no input is specified sxpm reads from standard input.
-.TP 8
-.B \-o \fIfilename\fP
-Write to the file \fIfilename\fP (overwrite if it already exists) and to
-standard output if \fIfilename\fP is '-'.
-.TP 8
-.B \-mono
-Use the colors specified for a monochrome visual.
-.TP 8
-.B \-grey4
-Use the colors specified for a 4 color greyscale visual.
-.TP 8
-.B \-grey
-Use the colors specified for a greyscale visual.
-.TP 8
-.B \-color
-Use the colors specified for a color visual.
-.TP 8
-.B \-pcmap
-Use a private colormap.
-.TP 8
-.B \-closecolors
-Try to use "close colors" before reverting to other visuals.
-.TP 8
-.B \-nod
-Do not display the pixmap in a window. (Useful when using as converter)
-.TP 8
-.B \-nom
-Do not use the clipmask if there is any.
-.TP 8
-.B \-sc \fIsymbol colorname\fP
-Override default color to \fIsymbol\fP to \fIcolorname\fP.
-.TP 8
-.B \-sp \fIsymbol pixelvalue\fP
-Override default color to \fIsymbol\fP to \fIpixelvalue\fP.
-.TP 8
-.B \-cp \fIcolorname pixelvalue\fP
-Override default color to \fIcolorname\fP to \fIpixelvalue\fP.
-.TP 8
-.B \-rgb \fIfilename\fP
-Search color names in the file \fIfilename\fP and write them out instead of
-the rgb values.
-.TP 8
-.B \-v
-Verbose - to print out extensions (stderr).

-.SH KNOWN BUGS
-Some window managers may not accept a pixmap which is not a bitmap as icon
-because this does not respect ICCCM, many of the well known ones will accept
-it though.
