XReadBitmapFile 3X11 __xorgversion__ XLIB FUNCTIONS XReadBitmapFile XReadBitmapFileData XWriteBitmapFile XCreatePixmapFromBitmapData XCreateBitmapFromData manipulate bitmaps int XReadBitmapFile( Display *display , Drawable d , char *filename , unsigned int *width_return, unsigned int *height_return , Pixmap *bitmap_return , int *x_hot_return, int *y_hot_return ); int XReadBitmapFileData( char *filename , unsigned int *width_return, unsigned int *height_return , unsigned char *data_return , int *x_hot_return, int *y_hot_return ); int XWriteBitmapFile( Display *display , char *filename , Pixmap bitmap , unsigned int width, unsigned int height , int x_hot, int y_hot ); Pixmap XCreatePixmapFromBitmapData ( Display *display , Drawable d , char *data , unsigned int width, unsigned int height , unsigned long fg, unsigned int bg , unsigned int depth ); Pixmap XCreateBitmapFromData( Display *display , Drawable d , char *data , unsigned int width, unsigned int height ); bitmap Specifies the bitmap. bitmap_return Returns the bitmap that is created. d Specifies the drawable that indicates the screen. data Specifies the data in bitmap format. data Specifies the location of the bitmap data. data_return Returns the bitmap data. depth Specifies the depth of the pixmap. display Specifies the connection to the X server. fg bg Specify the foreground and background pixel values to use. filename Specifies the file name to use. The format of the file name is operating-system dependent. width height Specify the width and height. width_return height_return Return the width and height values of the read in bitmap file. x_hot y_hot Specify where to place the hotspot coordinates (or -1,-1 if none are present) in the file. x_hot_return y_hot_return Return the hotspot coordinates. The  XReadBitmapFile  function reads in a file containing a bitmap. The file is parsed in the encoding of the current locale. The ability to read other than the standard format is implementation-dependent. If the file cannot be opened,  XReadBitmapFile  returns  BitmapOpenFailed . If the file can be opened but does not contain valid bitmap data, it returns  BitmapFileInvalid . If insufficient working storage is allocated, it returns  BitmapNoMemory . If the file is readable and valid, it returns  BitmapSuccess .  XReadBitmapFile  returns the bitmap's height and width, as read from the file, to width_return and height_return. It then creates a pixmap of the appropriate size, reads the bitmap data from the file into the pixmap, and assigns the pixmap to the caller's variable bitmap. The caller must free the bitmap using  XFreePixmap  when finished. If name_x_hot and name_y_hot exist,  XReadBitmapFile  returns them to x_hot_return and y_hot_return; otherwise, it returns -1,-1.  XReadBitmapFile  can generate  BadAlloc  and  BadDrawable  errors. The  XReadBitmapFileData  function reads in a file containing a bitmap, in the same manner as  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  XFree . The status and other return values are the same as for  XReadBitmapFile . The  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  BitmapOpenFailed . If insufficient memory is allocated,  XWriteBitmapFile  returns  BitmapNoMemory ; otherwise, on no error, it returns  BitmapSuccess . If x_hot and y_hot are not -1, -1,  XWriteBitmapFile  writes them out as the hotspot coordinates for the bitmap.  XWriteBitmapFile  can generate  BadDrawable  and  BadMatch  errors. The  XCreatePixmapFromBitmapData  function creates a pixmap of the given depth and then does a bitmap-format  XPutImage  of the data into it. The depth must be supported by the screen of the specified drawable, or a  BadMatch  error results.  XCreatePixmapFromBitmapData  can generate  BadAlloc  and  BadMatch  errors. The  XCreateBitmapFromData  function allows you to include in your C program (using  #include ) a bitmap file that was written out by  XWriteBitmapFile  (X version 11 format only) without reading in the bitmap file. The following example creates a gray bitmap: #include "gray.bitmap" Pixmap bitmap; bitmap = XCreateBitmapFromData(display, window, gray_bits, gray_width, gray_height); If insufficient working storage was allocated,  XCreateBitmapFromData  returns  None . It is your responsibility to free the bitmap using  XFreePixmap  when finished.  XCreateBitmapFromData  can generate a  BadAlloc  error.  BadAlloc  The server failed to allocate the requested resource or server memory.  BadDrawable  A value for a Drawable argument does not name a defined Window or Pixmap.  BadMatch  An  InputOnly  window is used as a Drawable.
