2004-08-10Relaxed the assertion for the 3x scaler a bit. Since it uses pointers toTorbjörn Andersson
uint16, it should be enough that dstPtr is even; it doesn't have to be a multiple of four. The old assertion failed for me when I used the 3x scaler without aspect ratio correction. svn-id: r14536

2003-10-02fix scaler compilation for MSVC6. However, the produced code stll seems to ↵Max Horn
be incorrect... Jamieson, maybe the MSVC6_COMPAT should be re-added then after all? svn-id: r10552
2003-09-29synced hq2x with upstream changes; some performance tweaks to hq2x/hq3x (I ↵Max Horn
think for bigger speed improvement we'd have to use ASM (with C++ fallback of course)... svn-id: r10494
2003-09-29templatized more of the scalers; also introduced template struct ColorMasks ↵Max Horn
(shortens/simplifies other code a bit) svn-id: r10489
2003-09-29split out scalers into separate source files in common/scaler; some ↵Max Horn
optimizations (in particular, the hq2x/hq3x scalers now are compiled into two versions, one for 555 and one for 565 mode) svn-id: r10488
2003-09-27get rid of explicit redMask/blueMask and use redBlueMask instead (this will ↵Max Horn
be useful should we choose to templatize the scalers for 555/565 mode optimizations) svn-id: r10451

2003-09-27Fixed template function compile quirks under MSVC6.Jamieson Christian
Apparently MSVC6 does not like overloading of template functions when the template arguments vary between versions of the overloaded function. I replaced interpolate16 with functions that have two different names, so MSVC6 won't see them as being the same function with [it insists] the same number of template arguments. svn-id: r10446
2003-09-27added hq2x scaler (no, I am not going to add hq4x anytime soon. It would be ↵Max Horn
another 4-5000 lines of code, and scaler.cpp already takes far too long to compile. Maybe we should seperate the scalers into several files in common/scaler/ ?) svn-id: r10438
2003-09-27added a FIXME (regarding optimization) to INTERPOLATE; added new template ↵Max Horn
function interpolate16 which is used by hq3x (advantage of the old trick which abused Q_INTERPOLATE: smaller & better optimized code; very easy to adapt the function for other uses, like for hq2x/hq3x. Drawback: scaler.cpp takes even longer to compile now :-) svn-id: r10433

svn-id: r8628
2003-06-22undoing this optimization: despite my initial sureness about this being ↵Max Horn
correct - I was wrong :-) just plug in 0xFFFFFFFF to see it (roughly spoken, we can loose the uppermost bits if we shift after the addition instead of before it) svn-id: r8627

2003-06-22Fixed the last (?) glitches around the mouse cursor [*] in aspect-ratioTorbjörn Andersson
correction mode by making sure that dirty rects always start on a line that won't have its colours changed by the stretching function. This was probably only noticeable when using the 1x scaler. [*] Actually, the glitches weren't specific to the mouse cursor, but it was useful for triggering them. svn-id: r8621
