Drawing through framebuff= er is OK, but console is broken - it looks like that even and odd columns are exchanged. Framebuffer structure of this mode is that even pixel is in high nibble and odd pixel is in low nibble. It looks like vga16fb use cfbimgblt.c/slow_imageblit in this mode for image-blit and this function in CFB4 writes even pixel in low nibble and odd pixel in high nibble. What is correct framebuffer structure for CFB4 mode? --=20 Elen sila lumenn' omentielvo Ondrej 'SanTiago' Zajicek (email: santiago@mail.cz, jabber: santiago@njs.ne= tlab.cz) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so." --GRPZ8SYKNexpdSJ7 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) iEYEARECAAYFAkQy2aIACgkQw1GB2RHercOoOwCeJuNMpft8T5VJFIOwFvkOEp2V VrQAn04iE8bb8UvtdyTOjwqPjFR+k+43 =QQfo -----END PGP SIGNATURE----- --GRPZ8SYKNexpdSJ7-- ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
