Is this format standard? How about using X bitmap format instead:
$ cat /usr/include/X11/bitmaps/left_ptr
#define left_ptr_width 16
#define left_ptr_height 16
#define left_ptr_x_hot 3
#define left_ptr_y_hot 1
static char left_ptr_bits[] = {
0x00, 0x00, 0x08, 0x00, 0x18, 0x00, 0x38, 0x00, 0x78, 0x00, 0xf8, 0x00,
0xf8, 0x01, 0xf8, 0x03, 0xf8, 0x07, 0xf8, 0x00, 0xd8, 0x00, 0x88, 0x01,
0x80, 0x01, 0x00, 0x03, 0x00, 0x03, 0x00, 0x00};
Then there would be no need of parsing.

Inspiried by xpm but simplified a bit as full xpm support just for a
built-in fallback cursor would have been overkill. The nice thing about
xpm is that you can use any text editor for editing icons.

Well. You still would have to convert it as qemu internal cursor format
is defined as 32bit depth, rgb with alpha channel. So it doesn't buy
you that much.
cheers,
Gerd

But for X bitmaps, you can use any real drawing program. The same
would also apply to full xpm. But read on.

There's still more wasted memory compared to binary format.
I think the best would be to store only the 32 bit image and perform
any conversions offline. This was the approach with for example
keyboard tables, we don't convert them at startup but the original
tables are retained as comments.

You would need _two_ bitmaps (e.g. mask and cursor, so that mask=1 gives
transparent, mask=0 cursor=0 gives black and mask=0 cursor=1 gives white).

Yes, but it's still packed more efficiently.
There's yet another way:
#define _ 0,
#define X 0xff000000,
#define o 0xffffffff,
{
_ _ _ X o X _ _ _
}
#undef _
#undef X
#undef o
This would not allow any drawing tool use, but there are no
conversions at startup.

Well. You can't have both. We can have a efficiently packed format
(i.e. two bitmaps). Or we can do it in a way which doesn't need
parsing, but that wouldn't be the most compact format ...

You're right, so packing or introducing a small conversion function is
not critical. I'd still prefer a standard format if possible.

Personally, I'd rather see Gerd's original format but read from a file
instead of hard coded in a .c file. IOW, a
/usr/share/qemu/default-cursor.qpm that contained the appropriate
strings. A couple extra lines that made it an xpm I think would be
worth it too.

xpms are designed to be easily #include-able, and parsing them that way
is easier than loading them at runtime. At least without adding a
dependency to libXpm.
So how about the following incremental RfC patch? It adds the cursors
as separate files which are standard xpm format. Nevertheless they are
compiled in, i.e. they can't be changed at runtime.
cheers,
Gerd

Uses VNC_ENCODING_RICH_CURSOR. Adding XCURSOR support should be
possible without much trouble. Shouldn't be needed though as
RICH_CURSOR is a superset of XCURSOR.
