mlelstv c950730079 add "best match" algorithm to wsfont and use this instead of a private 
function in rasops.
 2015-04-18 11:23:58 +00:00
riastradh fef866671e Don't leak f on failure. Noted by maxv@. 
Compile-tested only, with zaurus.

tsutsui b3d834c6ab Fix 1 bpp rasops copycols() op: 
- fix inverted shift direction in MBL() and MBR() macro in BE case
   (used by GETBITS() and PUTBITS() in copycols() function in rasops_bitops.h)
 - make all bitmask values unsigned and use proper uint32_t types for
   bitmap variables (to avoid arithmetic right shift)
 - fix various botches in right-to-left copy op (logic is taken from hp300)

Tested on bwtwo(4) on NetBSD/sparc.

macallan 936a44c065 rasops32_putchar_aa(): 
- underline the right characters
- make drawing slightly less horribly inefficient
- don't pretend to support a shadow fb
 2013-07-31 19:58:23 +00:00
tsutsui c789a2a4ba Fix another typo which causes decrement against a NULL pointer. 
Also revert rev 1.9, which shut up gcc's "uninitialized variable"
warning that actually pointed out the typo correctly.  Oh well.

tsutsui 9bc6043a7c Fix fatal (but probably unused) typo in ri->ri_hwbits case in copycols. 2013-05-21 15:50:09 +00:00

martin cadfec0fa5 Ooops, backout local change not intended to be commited with the last change 2013-03-21 21:01:10 +00:00
martin f02c188eea Add syntatic sugar to avoid hurting my eyes 2013-03-21 21:00:12 +00:00
macallan 98249f3c06 make anti-aliased character drawing work on hardware where stride != width * bytes per pixel 2012-10-23 15:12:59 +00:00
macallan 2320319a93 add another convenience function: 
rasops_get_cmap() which returns either the ANSI map or an R3G3B2 map,
depending on the rasops_info handed to it so drivers don't have to
duplicate this particular code snippet
 2012-04-19 06:57:39 +00:00
macallan b75a7aad08 fix what has to be a thinko - I doubt there's much hardware out there that 
uses BGR in 15/16 bit colour
 2012-04-17 12:06:25 +00:00
macallan 2ed32c39b4 use memset() to clear character cells instead of being terribly slow 2012-01-25 20:18:04 +00:00
macallan 8b892b4cb6 rasops8_putchar_aa(): 
render glyphs scanline by scanline into a 64bit-aligned buffer, then memcpy()
it into video memory instead of writing directly.
This gives >10% speedup even on valkyriefb, likely more on PCIe framebuffers.
 2012-01-25 16:38:27 +00:00
macallan 7f836eb389 make rasops_init()'s font selection code a bit less boneheaded by: 
- actually trying to pick a font which gets as close as possible to the
  requested terminal size
- accepting 0,0 as 'use system default' which can be changed by
   options RASOPS_DEFAULT_WIDTH=100
   options RASOPS_DEFAULT_HEIGHT=30
  default is 80x25
- putting alpha and bitmap fonts in the same list and making wsfont_find()
  aware of wether we support alpha fonts or not
- if supported, prefer alpha fonts over otherwise equally suitable bitmap
  fonts
 2012-01-11 15:52:32 +00:00
macallan d0517cd235 rasops8 expects the colour value replicated in every byte in devcmap[], so 
fix that for r3g3b2
 2012-01-04 20:17:05 +00:00
macallan f692d005a8 add support for anti-aliased fonts in r3g3b2 2012-01-04 20:16:20 +00:00
macallan 1e50f31f65 use CHAR_IN_FONT() and WSFONT_GLYPH() macros 2012-01-04 17:01:52 +00:00
macallan d5062c9e69 split putchar method into one for alpha fonts and one for bitmap fonts 2012-01-03 23:15:11 +00:00
macallan 0012d4bd2f add a macro to identify alpha fonts 2012-01-03 23:13:59 +00:00
macallan 5f8fd44534 add a new flag for ri_flg to allow drivers to request an r3g3b2 devcmap 
in 8 bit colour. Drivers are still responsible to generate an appropriate
colour map for the actual hardware.
For use with alpha blending which needs some sort of 'true' colour.
 2011-12-28 08:36:46 +00:00
macallan 3d90099590 skip the multiplications for alpha values of 0 and 255, just use background 
and foreground colours there
 2011-12-27 06:24:40 +00:00
macallan b7781c972a rename alpha variable to avoid conflict with a platform macro on alpha 2011-12-24 02:13:21 +00:00
macallan 99d1a7d487 support anti-aliased fonts ( as in, pre-rendered alpha maps ), for now only 
in rasops32 although adding support in 15, 16 and 24 would be trivial.
Enabled only if the driver explicitly requests it by setting the
RI_ENABLE_ALPHA flag.

tsutsui ae9c6cd78f Put underline properly (not upperline) on CCW screen. 
Tested on hpcarm WS003SH.
 2010-06-13 01:55:24 +00:00
macallan 21bc7f3caa Introduce a new flag for rasops_info to keep rasops_reconfig() from trying 
to allocate memory. Use this when calling rasops_reconfig() before it is safe
to call kmem_alloc().

macallan 38ea318425 remove now redundant ri = ... lines in putchar() methods 
Looks like none of my usual test builds used rasops2.c

nonaka 71c9ab4685 fix compile failure. 2010-05-04 12:36:37 +00:00
macallan 15a269471f autogenerate box drawing characters for fonts that don't have them, put them 
into an alternate font pointed at by the recently added mappings in wsfont,
adapt all putchar() methods except the rotated ones to use them
XXX no attempt has been made to make this work with rotation

nonaka b62fc9e203 Added Sharp W-ZERO3 series support. 2010-04-17 13:36:21 +00:00

macallan 8f881c7dd3 add support for shadow framebuffers 
tested on sparc with a cg12

macallan 8953b23350 make RI_CENTER and RI_FULLCLEAR work with a shadow framebuffer 2010-01-21 05:32:18 +00:00
cegger dc56dbbd97 ansify function definitions 2009-03-15 21:23:31 +00:00
dsl 82357f6d42 ANSIfy another 1261 function definitions. 
The only ones left in sys are beyond by sed script!
(or in sys/dist or sys/external)
Mostly they have function pointer parameters.
 2009-03-14 21:04:01 +00:00
dsl 454af1c0e8 Change about 4500 of the K&R function definitions to ANSI ones. 
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)
