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

74 | so if you experience any problem you should have a look at this file. | |
75 | ||
76 | ||
77 | <h2><a name="sec4">4. Installation</a></h2> | |
78 | <p> | |
79 | To obtain the XPM library, first uncompress and untar the compressed tar file | |
80 | in an appropriate directory. | |
81 | <p> | |
82 | Then you can either compile XPM via "imake" or in a stand-alone way. | |
83 | ||
84 | <h3><a name="sec4.1">4.1. With imake</a></h3> | |
85 | <p> | |
86 | Imakefiles are provided to build both shared and unshared libraries. | |
87 | However, building a shared lib is very OS dependent and often requires | |
88 | specific files which are not available. Also config files are often not | |
89 | set correctly for this task. So if it fails you can avoid trying to | |
90 | build one and simply build the static library instead. In order to do | |
91 | so you should edit the top Imakefile to add -DSharedLibXpm=NO to the | |
92 | definition of IMAKE_DEFINES as described. | |
93 | <p> | |
94 | The compilation and installation of the library and the sxpm program | |
95 | should only require you to edit the top Imakefile. But you should do so | |
96 | in order to specify the locations where the various files should be | |
97 | installed and to set the DEFINES variable accordingly to your system. | |
98 | <p> | |
99 | On Solaris 2.* the compilation works only in the native svr4 | |
100 | environment, avoid the bsd one or it won't compile. Especially you | |
101 | should be using /opt/SUNWspro/bin/cc and not /usr/ucb/cc. | |
102 | Also since the compiler is no longer part of the OS distribution a lot | |
103 | of people use gcc instead. This is fine, but be aware that the imake | |
104 | tool you get as part of the X Window System on a solaris box is | |
105 | configured for cc. Therefore the compilation using the generated | |
106 | Makefiles will not succeed unless you have changed the default | |
107 | configuration. An easy work around is to directly edit the generated | |
108 | lib/Makefile to change '-K pic' to '-fpic'. Fixing your imake | |
109 | configuration would be better though. | |
110 | <p> | |
111 | On Linux, if you do not use ELF yet you'd better get the binary | |
112 | distribution available from sunsite. Because it's really a pain to | |
113 | build a shared lib and the current XPM distribution doesn't contain | |
114 | the jump files you would need to do so. On the other hand people have | |
115 | had no problems building it using ELF. | |
116 | <p> | |
117 | Then execute the following command: | |
118 | <pre> | |
119 | xmkmf -a | |
120 | </pre> | |
121 | <p> | |
122 | or if this option is not supported by your version of xmkmf: | |
123 | <pre> | |
124 | xmkmf | |
125 | make Makefiles | |
126 | make includes | |
127 | make depend (optional) | |
128 | </pre> | |
129 | <p> | |
130 | Then simply execute: | |
131 | <pre> | |
132 | make | |
133 | </pre> | |
134 | <p> | |
135 | which will build the XPM library and the sxpm application. | |
136 | Then do: | |
137 | <pre> | |
138 | make install | |
139 | make install.man | |
140 | </pre> | |
141 | <p> | |
142 | which will install the library and the sxpm program and man page. | |
143 | <p> | |
144 | If it fails, be sure you have set the DEFINES correctly in the top | |
145 | Imakefile to suit your machine. | |
146 | ||
147 | <h4>NOTE ON USING IMAKE:</h4> | |
148 | <p> | |
149 | Building the XPM distribution with imake requires to have imake | |
150 | <strong>correctly installed and configured</strong> on your | |
151 | system. I do my best at tweaking the Imakefiles so they work with | |
152 | as many imake flavors people might have as possible but there is | |
153 | nothing I can do against wrong imake configurations. So if your | |
154 | build fails using imake, don't send me email for advice. Get your | |
155 | imake configuration fixed or forget about it! | |
156 | ||
157 | ||
158 | <h3><a name="sec4.2">4.2. Without imake</a></h3> | |
159 | <p> | |
160 | A set of makefiles is provided for those who do not have imake | |
161 | available on their system. However, this is only provided as a | |
162 | convenience and you should be considered as a starting point and not as | |
163 | something ready to use. These makefiles, called Makefile.noX, will most | |
164 | likely require some editing in order be set accordingly to your system. | |
165 | <p> | |
166 | Once this setting is done, you should be able to compile XPM, by | |
167 | executing the following command: | |
168 | <pre> | |
169 | make -f Makefile.noX | |
170 | </pre> | |
171 | <p> | |
172 | Then to install it, do: | |
173 | <pre> | |
174 | make -f Makefile.noX install | |
175 | </pre> | |
176 | ||
177 | ||
178 | <h2><a name="sec5">5. SXPM</a></h2> | |
179 | <p> | |
180 | In addition to the library the sxpm tool is provided to show XPM file and | |
181 | convert them from XPM1 or XPM2 to XPM version 3. If you have previously done | |
182 | 'make' or 'make all' you should already have it, otherwise just do: | |
183 | <pre> | |
184 | cd sxpm; make | |
185 | </pre> | |
186 | <p> | |
187 | This application shows you most of the features of XPM and its source can be | |
188 | used to quickly see how to use the provided functions. | |
189 | <p> | |
190 | By executing 'sxpm -help' you will get the usage. | |
191 | <p> | |
192 | Executing 'sxpm -plaid' will show a demo of the XpmCreatePixmapFromData | |
193 | function. The pixmap is created from the static variable plaid defined in the | |
194 | sxpm.c file. sxpm will end when you press the key 'q' in the created window. | |
195 | <p> | |
196 | Executing 'sxpm -plaid -sc lines_in_mix blue' will show the feature of | |
197 | overriding color symbols giving a colorname, executing 'sxpm -plaid -sp | |
198 | lines_in_mix 1' will show overriding giving a pixel value, and executing 'sxpm | |
199 | -plaid -cp red 0' will show overriding giving a color value. | |
200 | <p> | |
201 | Then you should try 'sxpm -plaid -o output' to get an output file using the | |
202 | XpmWriteFileFromPixmap function. | |
203 | <p> | |
204 | You can now try 'sxpm -plaid -o - -nod -rgb /usr/lib/X11/rgb.txt' to directly | |
205 | get the pixmap printed out on the standard output with colornames instead of | |
206 | rgb values. | |
207 | <p> | |
208 | Then you should try 'sxpm plaid.xpm' to use the XpmReadFileToPixmap function, | |
209 | and 'cat plaid_mask.xpm|sxpm' to see how "transparent pixels" are handled. | |
210 | <p> | |
211 | The XpmCreatePixmapFromData function is on purpose called without any XpmInfos | |
212 | flag to show the utility of this one. Indeed, compare the color section of the | |
213 | two files foo and bar obtained from 'sxpm -nod -plaid -o foo' and 'sxpm -nod | |
214 | plaid.xpm -o bar'. All the default colors and also the comments have been | |
215 | restored. | |
216 | <p> | |
217 | To end look at plaid_ext.xpm and try "sxpm -nod plaid_ext.xpm -v" to see how | |
218 | extensions are handled. | |
219 | <p> | |
220 | Of course, other combinations are allowed and should be tried. Thus, 'sxpm | |
221 | plaid.xpm -o output -nod' will show you how to convert a file from XPM1 or XPM2 | |
222 | to a XPM version 3 using sxpm. | |
223 | <p> | |
224 | See the manual page for more detail. | |

227 | <h2><a name="sec6">6. CXPM</a></h2> | |
228 | <p> | |
229 | The cxpm tool is provided to help you figure out whether an XPM file is correct | |
230 | or not with regard to its format. If you have previously done 'make' or | |
231 | 'make all' you should already have it, otherwise just do: | |
232 | <pre> | |
233 | cd cxpm; make | |
234 | </pre> | |
235 | <p> | |
236 | The related man page will tell you everything about it but here is a simple | |
237 | example of what it does: | |
238 | <pre> | |
239 | $ ./cxpm bogus_pixmap | |
240 | Xpm Error: Invalid XPM file. | |
241 | Error found line 3 near character 5 | |
242 | </pre> | |
243 | <p> | |
244 | It is pretty limited but at least, unlike sxpm, it gives you some hint on where | |
245 | the error occured within the file. | |
246 | ||
247 | ||
248 | <h2><a name="sec7">7. Other Tools</a></h2> | |
249 | <p> | |
250 | Several converters dealing with XPM and a pixmap editor can be found in the | |
251 | xpm-contrib distribution. Also I recommend the use of netpbm to do any kind of | |
252 | general image operations such as scaling, resizing, dithering, and to convert | |
253 | from and to any other image format. | |
254 | ||
