NetSurf / FrameBuffer #2

今日もframe buffer portをモニョった．

FTC_CMapCache_Lookup()でsegvるのは，error handlingがタコだったのとフォントへのパスがhardcodedで間違ってたのが原因．で，まずはSDL+freetype on Xで動くようになった．


さすがに黄色過ぎるので，internal pixel-colour変換を直すと，テキストの色は正しくなった．



endian dependな部分は泥臭くもあり，面白くもある．変な風にinternal pixel-colour変換がぶっ壊れると色がぶっ飛ぶ． :DDD

    any idea? http://dev.gentoo.gr.jp/~hiyuh/misc/BE2.patch

    it looks like only image ablend is broken, I guess.
 02/28 01:25:54 Kinnison
    looks like that

    blue and green traded in your pixel to colour

    text color is correct?
 02/28 01:33:03 kyllikki
    yes
 02/28 01:33:29 kyllikki
    the alpha blending is broken because the values its reading in to
    mix are wrong
 02/28 01:34:23 tlsa
    opaque images are wrong too
 02/28 01:34:33 hiyuh
    wtf :)
 02/28 01:34:57 tlsa
    well the screenshot is opaque, so is the logo image
 02/28 01:35:20 kyllikki
    I have no idea then
 02/28 01:35:38 kyllikki
    maybe the image formatters are getting it wrong on big endian systems?
 02/28 01:35:58 tlsa
    they'd be bust when he runs nsgtk
 02/28 01:38:40 hiyuh
    nsgtk works correctly on BE.
 02/28 01:40:11 tlsa
    there's something more wrong than just channel swapping
 02/28 01:40:36 tlsa
    cos the logo in the download box and the logo in the mast head should
    be the same colour
 02/28 01:40:46 tlsa
    but they are completely different
 02/28 01:45:01 tlsa
    actually, that's cos the background is different and the images are
    incorrectly getting alpha values other than opaque
 02/28 01:47:36 tlsa
    does the gtk build swap bitmap data round on BE?
 02/28 01:49:11 tlsa
    cos it looks perfect except for bitmaps
 02/28 01:54:21 hiyuh
    IIRC, nsgtk's image problems on BE was only in libnsgif code base
    (maybe it was in netsurf/image/gifread.c).
 02/28 01:56:37 tlsa
    well there's something certainly wrong with images
 02/28 01:56:50 tlsa
    and nothing wrong with text colours
 02/28 01:57:20 hiyuh
    true

と言う訳で，もう少しゴニョる必要があるのだったのだった． :)
