[cairo] Cairo Font text

[Eric Feillant]

Hi Cairo users,


I  have some troubles with overlaying text on a surface . The texts i 
overlay on the background color is not very clean, it seems to move a 
little bit on the shape.

When text change, it seems like if it was repainted again. My program 
use a loop to keep the overlay on the stream (IP CAMERA OVERLAY API).


The surface is :
  surface = cairo_image_surface_create(CAIRO_FORMAT_ARGB32, 
OVERLAY_WIDTH, OVERLAY_HEIGHT);


the text with font :

cairo_select_font_face(cr, "Sans", 
CAIRO_FONT_SLANT_NORMAL,CAIRO_FONT_WEIGHT_BOLD);


Do you think i could use another font ? another method ?

Any suggest is welcome,


Thank you

Eric
