Subject: [9fans] libdraw α differences between plan 9 and p9p
Date: Fri, 31 Mar 2006 11:16:20 -0600 [thread overview]
Message-ID: <58016f906ee4ee8db79b500cdecbe236@quanstro.net> (raw)
i've noticed a difference in how the α channel looks in p9p vs.
plan 9. for example when porting mahjongg to plan9port,
i need to make this change to make the selection highlighting
apparent:
/sys/src/games/mahjongg//mahjongg.c:75,81 - ./mahjongg.c:75,81
{
Rectangle one = Rect(0, 0, 1, 1);
- selected = eallocimage(one, 1, RGBA32, setalpha(DPalebluegreen, 0x5f));
+ selected = eallocimage(one, 1, RGBA32, setalpha(DPalebluegreen, 0x9f));
is a mapping needed to convert libdraw α values to X?
- erik
p.s. p9p mahjongg is on sources but it's missing the tile sets and lib configuration.
