The net effect is that it's - * impossible to externally create an image surface with this - * format. This is perhaps a good thing since we also neglected to fix - * up things like cairo_surface_write_to_png() for the new format - * (-Wswitch-enum will tell you where). Is it obvious that format was - * added in haste? - * - * The reason for the new format was to allow the xlib backend to be - * used on X servers with a 565 visual. So the new format did its job - * for that, even without being considered "valid" for the sake of - * things like cairo_image_surface_create(). - * - * Since 1.2.0 we ran into the same situation with X servers with BGR - * visuals. This time we invented #cairo_internal_format_t instead, - * (see it for more discussion). - * - * The punchline is that %CAIRO_FORMAT_VALID must not conside any - * internal format to be valid. Also we need to decide if the - * RGB16_565 should be moved to instead be an internal format. If so, - * this macro need not change for it. (We probably will need to leave - * an RGB16_565 value in the header files for the sake of code that - * might have that value in it.) - * - * If we do decide to start fully supporting RGB16_565 as an external - * format, then %CAIRO_FORMAT_VALID needs to be adjusted to include - * it. But that should not happen before all necessary code is fixed - * to support it (at least cairo_surface_write_to_png() and a few spots - * in cairo-xlib-surface.c--again see -Wswitch-enum). - */ -#define CAIRO_FORMAT_VALID(format) ((format) >= CAIRO_FORMAT_ARGB32 && \ - (format) <= CAIRO_FORMAT_RGB30) - -/* pixman-required stride alignment in bytes. */ -#define CAIRO_STRIDE_ALIGNMENT (sizeof (uint32_t)) -#define CAIRO_STRIDE_FOR_WIDTH_BPP(w,bpp) \ - ((((bpp)*(w)+7)/8 + CAIRO_STRIDE_ALIGNMENT-1) & -CAIRO_STRIDE_ALIGNMENT) - -#define CAIRO_CONTENT_VALID(content) ((content) && \ - (((content) & ~(CAIRO_CONTENT_COLOR | \ - CAIRO_CONTENT_ALPHA | \ - CAIRO_CONTENT_COLOR_ALPHA))\ - == 0)) - -cairo_private int -_cairo_format_bits_per_pixel (cairo_format_t format) cairo_const;
