169 Specifies the bitmap.
170 .IP \fIbitmap_return\fP 1i
171 Returns the bitmap that is created.
172 .ds Dr \ that indicates the screen
174 Specifies the drawable\*(Dr.
176 Specifies the data in bitmap format.
178 Specifies the location of the bitmap data.
179 .IP \fIdata_return\fP 1i
180 Returns the bitmap data.
182 Specifies the depth of the pixmap.
184 Specifies the connection to the X server.
189 Specify the foreground and background pixel values to use.
190 .IP \fIfilename\fP 1i
191 Specifies the file name to use.
192 The format of the file name is operating-system dependent.
197 Specify the width and height.
198 .IP \fIwidth_return\fP 1i
201 .IP \fIheight_return\fP 1i
202 Return the width and height values of the read in bitmap file.

213 Return the hotspot coordinates.
217 function reads in a file containing a bitmap.
218 The file is parsed in the encoding of the current locale.
219 The ability to read other than the standard format
220 is implementation-dependent.
221 If the file cannot be opened,
224 .ZN BitmapOpenFailed .
225 If the file can be opened but does not contain valid bitmap data,
227 .ZN BitmapFileInvalid .
228 If insufficient working storage is allocated,
231 If the file is readable and valid,
236 returns the bitmap's height and width, as read
237 from the file, to width_return and height_return.
238 It then creates a pixmap of the appropriate size,
239 reads the bitmap data from the file into the pixmap,
240 and assigns the pixmap to the caller's variable bitmap.
241 The caller must free the bitmap using
244 If \fIname\fP_x_hot and \fIname\fP_y_hot exist,
246 returns them to x_hot_return and y_hot_return;
247 otherwise, it returns \-1,\-1.
257 .ZN XReadBitmapFileData
258 function reads in a file containing a bitmap, in the same manner as
259 .ZN XReadBitmapFile ,
260 but returns the data directly rather than creating a pixmap in the server.
261 The bitmap data is returned in data_return; the client must free this
262 storage when finished with it by calling
264 The status and other return values are the same as for
265 .ZN XReadBitmapFile .
269 function writes a bitmap out to a file in the X Version 11 format.
270 The name used in the output file is derived from the file name
271 by deleting the directory prefix.
272 The file is written in the encoding of the current locale.
273 If the file cannot be opened for writing,
275 .ZN BitmapOpenFailed .
276 If insufficient memory is allocated,
280 otherwise, on no error,
283 If x_hot and y_hot are not \-1, \-1,
285 writes them out as the hotspot coordinates for the bitmap.
295 .ZN XCreatePixmapFromBitmapData
296 function creates a pixmap of the given depth and then does a bitmap-format
299 The depth must be supported by the screen of the specified drawable,
304 .ZN XCreatePixmapFromBitmapData
312 .ZN XCreateBitmapFromData
313 function allows you to include in your C program (using
315 a bitmap file that was written out by
317 (X version 11 format only) without reading in the bitmap file.
318 The following example creates a gray bitmap:
321 \&#include "gray.bitmap"
324 bitmap = XCreateBitmapFromData(display, window, gray_bits, gray_width, gray_height);
327 If insufficient working storage was allocated,
328 .ZN XCreateBitmapFromData
331 It is your responsibility to free the
336 .ZN XCreateBitmapFromData
343 The server failed to allocate the requested resource or server memory.
346 A value for a Drawable argument does not name a defined Window or Pixmap.
351 window is used as a Drawable.
