+<h2><a name="Q1">1. How do I convert my images to or from XPM ?</a></h2>
+<p>
+  Netpbm is surely the best image conversion package that I know of. It defines
+  formats for color, gray and monochrome images and provides a set of filters.
+  Thus a GIF image can be converted to XPM with something like:
+<p>
+  $ giftoppm youricon.gif | ppmtoxpm > youricon.xpm
+<p>
+  The latest release can be found at least from wuarchive.wustl.edu
+  (128.252.135.4), directory /graphics/graphics/packages/NetPBM
+
+
+<h2><a name="Q2">2. Why are my XPM files said to be invalid ?</a></h2>
+<p>
+  There are three official versions of the XPM format. The XPM library since
+  version 3.3 can read all them but writes out only XPM 3. Also the small
+  program called sxpm which is part of the XPM library package can be used to
+  automatically translate XPM 1 and 2 files to XPM 3 with a command such as:
+<p>
+  $ sxpm -nod yourxpm1or2file -o yourxpm3file
+<p>
+  Also, the XPM format defines "None" to be the color name meaning
+  "transparent", but IXI used to hack the XPM library in its early days to
+  handle transparency as "#Transparent". This makes IXI format not compatible
+  with the official XPM format, and so not readable neither by the official XPM
+  library nor any of the programs built on top of it.
+<p>
+  The only solutions are either to stick on IXI programs which can deal with
+  their format or convert your files to the standard XPM format. This can be
+  done simply by changing "#Transparent" to "None".
+
+
+<h2><a name="Q3">3. Why does my program core dumps using XPM ?</a></h2>
+<p>
+  Be sure the XpmAttributes structure you pass by reference has a valid
+  valuemask. You can give NULL instead if you don't want to use an
+  XpmAttributes but if you do, you MUST initialize its valuemask component to
+  some valid value, at least 0, otherwise unpredictable errors can occur.
+<p>
+  So instead of doing something like:
+<pre>
+      XpmAttributes attrib;
+
+      XpmReadFileToPixmap(dpy, d, filename, &amp;pixmap, &amp;mask, &amp;attrib);
+</pre>
+<p>
+  you should do:
+<pre>
+      XpmAttributes attrib;
+
+      attrib.valuemask = 0;
+      XpmReadFileToPixmap(dpy, d, filename, &amp;pixmap, &amp;mask, &amp;attrib);
+</pre>
+
+
+<h2><a name="Q4">4. Why does my program core dumps using XPM with a widget ?</a></h2>
+<ul>
+<li>First the XPM library is Xlib level, so don't pass your widget as a
+    Drawable parameter. A Drawable is either a Window or a Pixmap. The widget's
+    window can do the job but:
+
+<li>Then a widget only gets a Window when realized, so passing XtWindow(widget)
+    with a not yet realized widget is wrong. Either realize you widget first or
+    use another window. Since the Drawable parameter is only used to specify
+    the screen to which the pixmap must be created on, most of the time the
+    default root window is just fine.
+</ul>
+
+
+<h2><a name="Q5">5. How can I get a non rectangular icon using XPM ?</a></h2>
+<p>
+  The X Window System does not support transparent color. However there are
+  several ways you can use to get the same visual effect using XPM:
+<ul>
+<li>First you can use the None color to get a shape mask and use it as
+    explained below (question 7).
+
+<li>Second you can define a symbolic color name such as "mask" in the XPM
+    format file, then use the color overriding mechanism to set this symbolic
+    color to the color of the underlying object. Note that in this case the XPM
+    library won't create a shape mask, and that if the color of the underlying
+    object is changed then you'll have to create a new pixmap.
+</ul>
+
+
+<h2><a name="Q6">6. What exactly triggers the creation of a mask when using XPM ?</a></h2>
+<p>
+  Basically a mask is created if "None" is used as one of the color of the
+  pixmap. Be aware that this is not only true if it is used in the XPM of the
+  pixmap since the colors can be overridden at load time. So a mask is created
+  if the "None" color is used at load time, coming either from the XPM
+  definition or the color overriding.
+
+
+<h2><a name="Q7">7. How should I use the mask ?</a></h2>
+<p>
+  There are basically two ways of using the mask:
+<ul>
+<li>Use the mask as a shapemask with the X11 Nonrectangular Saphe Window
+    Extension. Typically this is what should be done when the icon is used in a
+    desktop.
+
+<li>Use the mask as a clipmask in the GC you pass to XCopyArea when drawing the
+    pixmap. So the "transparent" pixels being not actually drawn will get the
+    underlying pixels colors.
+</ul>
+
+
+<h2><a name="Q8">8. Is there a string to pixmap converter for Motif ?</a></h2>
+<p>
+ Yes, Motif 2.0 or later does support XPM pixmaps as well as XBM bitmaps.
+
+
+<h2><a name="Q9">9. How can I edit XPM icons ?</a></h2>
+<p>
+  As listed below several editors either commercial or not are supporting the
+  XPM format. However, pixmap is the one I would recommend since it is freely
+  available and, being fully dedicated to XPM, it allows to edit all the
+  special things, such as the symbolic color names, which makes XPM different
+  from all the other image formats. Pixmap can always be found by ftp from
+  ftp.x.org (contrib) and avahi.inria.fr (pub/pixmap).

+<h2><a name="Q10">10. Is there a collection of icons somewhere ?</a></h2>
+<p>
+  At least there is one freely available: Anthony's X Icon Library. You can
+  found it on several ftp servers, such as <a href="ftp://server.berkeley.edu/pub/AIcons">server.berkeley.edu/pub/AIcons</a>. It
+  contains only small icons (less than about 100x100 pixels in size) which are

+  Black & White icons in XBM.
+
+
+<h2><a name="Q11">11. The documentation fails to print out. Why ?</a></h2>
+<p>
+  The PostScript documentation file is formatted for US letter paper. Frame
+  Maker tries very hard to ensure that you have the right paper and punts if
+  you don't. However, you can easily work around this problem by applying the
+  following patch. If for some reason applying the patch fails, you can still
+  do it by hand. Just locate the corresponding block in the PS file and remove
+  the lines with a leading '-' character.
+  By the way, this applies to any doc generated by Frame Maker. The
+  corresponding block might be slightly different depending on which version of
+  Frame Maker was used, but it is still easy to locate.

+The XPM library for Amiga works best with AmigaOS 3.x, but will work
+(with limited color support) with earlier OS versions too. It can be
+compiled with both SAS/C and GCC (makefiles are included).
+

+README.MSW	hedu@cul-ipn.uni-kiel.de	5/94
+
+		The XPM library for MS-Windows
+		
+Motivated by the wxWindows library, which is a (freely available) toolkit
+for developing multi-platform, graphical applications from the same body 
+of C++ code, I wanted to have XPM pixmaps for MS-windows. Instead of rewriting 
+a XPM-parser I managed to port the XPM-library-code to MS-windows.
+Thanks to Anaud Le Hors this became a part of the official XPM-library.
+
+Until now it's only used together with wxWindows. And even there it's more 
+a kind of beta. But it should be possible to run it as a simple libxpm.a 
+without wxWindows.
+
+The key is a transformation of some X types plus some basic X functions.
+There is not yet a special MSW-API, so you should know the X types used.
+
+The following is done in simx.h:
+
+typedef HDC Display;
+typedef COLORREF Pixel;
+
+typedef struct {
+    Pixel pixel;
+    BYTE red, green, blue;
+}      XColor;
+
+typedef struct {
+    HBITMAP bitmap;
+    unsigned int width;
+    unsigned int height;
+    unsigned int depth;
+}      XImage;
+
+With these defines and the according functions from simx.c you can call
+XPM-functions the way it's done under X windows. It can look like this:
+
+	ErrorStatus=XpmCreateImageFromData(&dc, data, 
+				&ximage,(XImage **)NULL, &xpmAttr);
+	ms_bitmap = ximage->bitmap;
+	// releases the malloc,but do not destroy the bitmap
+	XImageFree(ximage);
+	
+Supported functions are the Xpm*Image* but not the Xpm*Pixmap*.
+
+DRAWBACKS:
+The main drawback is the missing support for Colormaps! There was nothing for
+it in wxWindows, so I did not know how to deal with Colormaps.
+
+The size of the pixmaps is bounded by malloc() (width*height*2 < 64K).
+
+Close colors do not look that close. But that seems to be the window system.
+
+Neither a special API for MSW nor a special MSW documentation other than this.
+(I can only point you to wxxpm as an example , see below.)
+
+INSTALLATION:
+There is not yet a makefile with it. Simply take all the *.c files
+into your project except the files related to Pixmap operations: *P*.c.
+!!!You MUST set FOR_MSW on the preprocessor options!!!
+(You might uncomment NEED_STRCASECMP in xpm.h if it's in your lib)
+This should compile into libxpm.a. Good luck...
+

+Applications Institute (University of Edinburgh) by anonymous FTP.

+
+================================================================
+Some fixes and comments by Jan Wielemaker (jan@swi.psy.uva.nl),
+Oct 24, 1996:
+
+	* Please try not to disturb me on this, XPM is not my
+	piece of cake.
+
+	* Hermann Dunkel has appearently moved in virtual space.
+
+Changes:
+
+	* I've used the xpm package under NT 4.0 and MSVC++ 4.2.
+
+	* I've made a big performance improvement in 
+	ParseAndPutPixels(), fixed creation of the mask in
+	SetColor() in create.c.  I looked into XCreateImage()
+	in simx.c, but commented out my improvement for reasons
+	you'll find there.  If you know what is going on, statement
+	(1) does not apply to you.
+
+Comments on installation:
+
+	* Donot include the to/from pixmap files into the project.
+	These are the ones containing a capital P somewhere in their
+	name.  You can also first include all, and then remove all
+	the files you get errors on :-)
+
+	* The DC that is requested should be a valid memory DC, thus
+	CreateCompatibleDC(NULL) provides a good generic one, but
+	GetDC(NULL) doesn't!  This costed me some time.
+
+	* The real difficulty is using the mask, mostly due to the
+	bad documentation.  If 95 or NT is your target, use:
+
+	MaskBlt(context.hdc,	// Destination DC
+		x, y, w, h,	// Destination area
+		mhdc,		// Memory DC with the image selected
+		sx, sy,		// Source X,Y
+		msk,		// HBITMAP of the mask
+		sx, sy,		// Mask X,Y
+		MAKEROP4(SRCPAINT, SRCCOPY));	// The magic op code.

+<h2><a name="sec1">1. What Is XPM?</a></h2>
+<p>
+XPM (X PixMap) is a format for storing/retrieving X pixmaps to/from files.
+<p>
+Here is provided a library containing a set of four functions, similar to the
+X bitmap functions as defined in the Xlib: <code>XpmCreatePixmapFromData</code>,
+<code>XpmCreateDataFromPixmap</code>, <code>XpmReadFileToPixmap</code> and <code>XpmWriteFileFromPixmap</code> for
+respectively including, storing, reading and writing this format, plus four
+other: <code>XpmCreateImageFromData</code>, <code>XpmCreateDataFromImage</code>, <code>XpmReadFileToImage</code> and
+<code>XpmWriteFileFromImage</code> for working with images instead of pixmaps.
+<p>
+This new version provides a C includable format, defaults for different types
+of display: monochrome/color/grayscale, hotspot coordinates and symbol names
+for colors for overriding default colors when creating the pixmap. It provides
+a mechanism for storing information while reading a file which is re-used
+while writing. This way comments, default colors and symbol names aren't lost.
+It also handles "transparent pixels" by returning a shape mask in addition to
+the created pixmap.
+<p>
+See the XPM Manual for details.
+

+
+
+<h2><a name="sec4">4. Installation</a></h2>
+<p>
+To obtain the XPM library, first uncompress and untar the compressed tar file
+in an appropriate directory.
+<p>
+Then you can either compile XPM via "imake" or in a stand-alone way.
+
+<h3><a name="sec4.1">4.1. With imake</a></h3>
+<p>
+	Imakefiles are provided to build both shared and unshared libraries.
+	However, building a shared lib is very OS dependent and often requires
+	specific files which are not available. Also config files are often not
+	set correctly for this task. So if it fails you can avoid trying to
+	build one and simply build the static library instead. In order to do
+	so you should edit the top Imakefile to add -DSharedLibXpm=NO to the
+	definition of IMAKE_DEFINES as described.
+<p>
+	The compilation and installation of the library and the sxpm program
+	should only require you to edit the top Imakefile. But you should do so
+	in order to specify the locations where the various files should be
+	installed and to set the DEFINES variable accordingly to your system.
+<p>
+	On Solaris 2.* the compilation works only in the native svr4
+	environment, avoid the bsd one or it won't compile. Especially you
+	should be using /opt/SUNWspro/bin/cc and not /usr/ucb/cc.
+	Also since the compiler is no longer part of the OS distribution a lot
+	of people use gcc instead. This is fine, but be aware that the imake
+	tool you get as part of the X Window System on a solaris box is
+	configured for cc. Therefore the compilation using the generated
+	Makefiles will not succeed unless you have changed the default
+	configuration. An easy work around is to directly edit the generated
+	lib/Makefile to change '-K pic' to '-fpic'. Fixing your imake
+	configuration would be better though.
+<p>
+	On Linux, if you do not use ELF yet you'd better get the binary
+	distribution available from sunsite. Because it's really a pain to
+	build a shared lib and the current XPM distribution doesn't contain
+	the jump files you would need to do so. On the other hand people have
+	had no problems building it using ELF.
+<p>
+	Then execute the following command:
+<pre>
+		xmkmf -a
+</pre>
+<p>
+	or if this option is not supported by your version of xmkmf:
+<pre>
+		xmkmf
+		make Makefiles
+		make includes
+		make depend		(optional)
+</pre>
+<p>
+	Then simply execute: 
+<pre>
+		make
+</pre>
+<p>
+	which will build the XPM library and the sxpm application. 
+	Then do:
+<pre>
+	     	make install
+		make install.man
+</pre>
+<p>
+	which will install the library and the sxpm program and man page.
+<p>
+	If it fails, be sure you have set the DEFINES correctly in the top
+	Imakefile to suit your machine.
+
+<h4>NOTE ON USING IMAKE:</h4>
+<p>
+	Building the XPM distribution with imake requires to have imake
+	<strong>correctly installed and configured</strong> on your
+	system. I do my best at tweaking the Imakefiles so they work with
+	as many imake flavors people might have as possible but there is
+	nothing I can do against wrong imake configurations. So if your
+	build fails using imake, don't send me email for advice. Get your
+	imake configuration fixed or forget about it!
+
+
+<h3><a name="sec4.2">4.2. Without imake</a></h3>
+<p>
+	A set of makefiles is provided for those who do not have imake
+	available on their system. However, this is only provided as a
+	convenience and you should be considered as a starting point and not as
+	something ready to use. These makefiles, called Makefile.noX, will most
+	likely require some editing in order be set accordingly to your system.
+<p>
+	Once this setting is done, you should be able to compile XPM, by
+	executing the following command:
+<pre>
+	        make -f Makefile.noX
+</pre>
+<p>
+	Then to install it, do:
+<pre>
+		make -f Makefile.noX install
+</pre>
+
+
+<h2><a name="sec5">5. SXPM</a></h2>
+<p>
+In addition to the library the sxpm tool is provided to show XPM file and
+convert them from XPM1 or XPM2 to XPM version 3. If you have previously done
+'make' or 'make all' you should already have it, otherwise just do:
+<pre>
+		      cd sxpm; make
+</pre>
+<p>
+This application shows you most of the features of XPM and its source can be
+used to quickly see how to use the provided functions.
+<p>
+By executing 'sxpm -help' you will get the usage.
+<p>
+Executing 'sxpm -plaid' will show a demo of the XpmCreatePixmapFromData
+function. The pixmap is created from the static variable plaid defined in the
+sxpm.c file. sxpm will end when you press the key 'q' in the created window.
+<p>
+Executing 'sxpm -plaid -sc lines_in_mix blue' will show the feature of
+overriding color symbols giving a colorname, executing 'sxpm -plaid -sp
+lines_in_mix 1' will show overriding giving a pixel value, and executing 'sxpm
+-plaid -cp red 0' will show overriding giving a color value.
+<p>
+Then you should try 'sxpm -plaid -o output' to get an output file using the
+XpmWriteFileFromPixmap function.
+<p>
+You can now try 'sxpm -plaid -o - -nod -rgb /usr/lib/X11/rgb.txt' to directly
+get the pixmap printed out on the standard output with colornames instead of
+rgb values.
+<p>
+Then you should try 'sxpm plaid.xpm' to use the XpmReadFileToPixmap function,
+and 'cat plaid_mask.xpm|sxpm' to see how "transparent pixels" are handled.
+<p>
+The XpmCreatePixmapFromData function is on purpose called without any XpmInfos
+flag to show the utility of this one. Indeed, compare the color section of the
+two files foo and bar obtained from 'sxpm -nod -plaid -o foo' and 'sxpm -nod
+plaid.xpm -o bar'. All the default colors and also the comments have been
+restored.
+<p>
+To end look at plaid_ext.xpm and try "sxpm -nod plaid_ext.xpm -v" to see how
+extensions are handled.
+<p>
+Of course, other combinations are allowed and should be tried. Thus, 'sxpm
+plaid.xpm -o output -nod' will show you how to convert a file from XPM1 or XPM2
+to a XPM version 3 using sxpm.
+<p>
+See the manual page for more detail.
+
+
+<h2><a name="sec6">6. CXPM</a></h2>
+<p>
+The cxpm tool is provided to help you figure out whether an XPM file is correct
+or not with regard to its format. If you have previously done 'make' or
+'make all' you should already have it, otherwise just do:
+<pre>
+		      cd cxpm; make
+</pre>
+<p>
+The related man page will tell you everything about it but here is a simple
+example of what it does:
+<pre>
+$ ./cxpm bogus_pixmap
+Xpm Error: Invalid XPM file.
+Error found line 3 near character 5
+</pre>
+<p>
+It is pretty limited but at least, unlike sxpm, it gives you some hint on where
+the error occured within the file.
+
+
+<h2><a name="sec7">7. Other Tools</a></h2>
+<p>
+Several converters dealing with XPM and a pixmap editor can be found in the
+xpm-contrib distribution. Also I recommend the use of netpbm to do any kind of
+general image operations such as scaling, resizing, dithering, and to convert
+from and to any other image format.
