Specifies the bitmap.
Returns the bitmap that is created.
Specifies the drawable that indicates the screen.
Specifies the data in bitmap format.
Specifies the location of the bitmap data.
Returns the bitmap data.
Specifies the depth of the pixmap.
Specifies the connection to the X server.
Specify the foreground and background pixel values to use.
Specifies the file name to use. The format of the file name is operating-system dependent.
Specify the width and height.
Return the width and height values of the read in bitmap file.
Specify where to place the hotspot coordinates (or -1,-1 if none are present) in the file.
Return the hotspot coordinates.
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:
0 0>=40 .vs 0u 0<=39 .vs 0p #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.
