thank you Werner, it's working fine now. So this issue was (again) from my
english skill, I wasn't sure of scanline and pitch means...

Hi Glynn,
so I guess, length of face-glyph-bitmap.buffer =
1(gray lvl)*16(width)*8(rows)=128 unsigned chars, right ?
Right answer, wrong reasoning; width should be replaced by pitch. The
two values may differ if there is padding between lines.
thx for this.

Hi, I try to use freetype with xlib, I , I need to pass a char type array
(RGBA/pixel) to a xlib function.
from freetype I got :
face-glyph-bitmap.pixel_mode = 2
so if I understood corectly in face-glyph-bitmap.buffer datas are stored in
gray level.
face-glyph-bitmap.rows=16
Hi Alan,

Hi Glynn and other guys,
while(XPending(dpy)==0){
usleep(100);
updateClock(myClock);
Ugh. This causes the process to be scheduled up to 10,000 times per
second, which is almost a busy wait. I would expect this process to

Hi cairomailing list,
I got a problem, when I use this code :
s=cairo_xlib_surface_create(dpy, wndw.frame, DefaultVisual(dpy, 0),
640, 480);
c=cairo_create(s);
p=cairo_pattern_create_linear(10.10,0.10,0.0,450.0);
cairo_pattern_add_color_stop_rgba(p,0,1,0,0,1);
Hi Glynn,
first thanks.
You should redraw the window (or at least the rectangle specified in
the XExposeEvent structure) in response to an Expose event. Ideally,
you should collect any pending Expose events and perform the minimum
amount of work necessary to redraw the specified rectangles (i.e.
Hi guys from xorgand cairomailling list,
I sent this mail to both of you because I don't know who can explains to me
something. I wrote a small code, it's just a window where you should see the

If you hit space the window moves, if you hit q the wm will exit(ok ok it's

Hi Peter,
XQueryPointer(dpy,rootwin,None,None,mousex,mousey,None,None,None);
// problem...
none of these may be NULL (or None, which is just 0 anyway). you do need to
provide some valid pointers here.
well, yesterday I tried with all pointers settled, X crashed. Today I try
again,
I still don't know why the hello world code does not working as I expect. But
I write a piece of code who works as expected. I'm not sure that's well
written, (if someone want to take a look). Mouse pointer is rendered, when a
button is pressed or when a key is release the while loop is stoped.
Hi,
