+otherwise, it returns \-1,\-1. +.LP +.ZN XReadBitmapFile +can generate +.ZN BadAlloc +and +.ZN BadDrawable +errors. +.LP +The +.ZN XReadBitmapFileData +function reads in a file containing a bitmap, in the same manner as +.ZN XReadBitmapFile , +but returns the data directly rather than creating a pixmap in the server. +The bitmap data is returned in data_return; the client must free this +storage when finished with it by calling +.ZN XFree . +The status and other return values are the same as for +.ZN XReadBitmapFile . +.LP +The +.ZN XWriteBitmapFile +function writes a bitmap out to a file in the X Version 11 format. +The name used in the output file is derived from the file name +by deleting the directory prefix. +The file is written in the encoding of the current locale. +If the file cannot be opened for writing, +it returns +.ZN BitmapOpenFailed . +If insufficient memory is allocated, +.ZN XWriteBitmapFile +returns +.ZN BitmapNoMemory ; +otherwise, on no error, +it returns +.ZN BitmapSuccess . +If x_hot and y_hot are not \-1, \-1, +.ZN XWriteBitmapFile +writes them out as the hotspot coordinates for the bitmap. +.LP +.ZN XWriteBitmapFile +can generate +.ZN BadDrawable +and +.ZN BadMatch +errors. +.LP +The +.ZN XCreatePixmapFromBitmapData +function creates a pixmap of the given depth and then does a bitmap-format +.ZN XPutImage +of the data into it. +The depth must be supported by the screen of the specified drawable, +or a +.ZN BadMatch +error results. +.LP +.ZN XCreatePixmapFromBitmapData +can generate +.ZN BadAlloc +and +.ZN BadMatch +errors. +.LP +The +.ZN XCreateBitmapFromData +function allows you to include in your C program (using +.ZN #include ) +a bitmap file that was written out by +.ZN XWriteBitmapFile +(X version 11 format only) without reading in the bitmap file. +The following example creates a gray bitmap: +.LP +.Ds 0 +\&#include "gray.bitmap" +.sp 6p +Pixmap bitmap; +bitmap = XCreateBitmapFromData(display, window, gray_bits, gray_width, gray_height); +.De +.LP +If insufficient working storage was allocated, +.ZN XCreateBitmapFromData +returns +.ZN None . +It is your responsibility to free the +bitmap using +.ZN XFreePixmap +when finished. +.LP +.ZN XCreateBitmapFromData +can generate a +.ZN BadAlloc +error. +.SH DIAGNOSTICS +.TP 1i +.ZN BadAlloc +The server failed to allocate the requested resource or server memory. +.TP 1i +.ZN BadDrawable +A value for a Drawable argument does not name a defined Window or Pixmap. +.TP 1i +.ZN BadMatch +An +.ZN InputOnly +window is used as a Drawable. +.SH "SEE ALSO" +XCreatePixmap(3X11), +XPutImage(3X11) +.br +\fI\*(xL\fP |
