* Touch input support for WindowsGravatar Brian Osman2017-06-07
| | | | | | | | | | | | | | | | | | | Had to add some logic to avoid touch and mouse cross-talk, because (at least on my laptop), the touch screen generates both kinds of events. This seems really useful [1] for the many [2] Skia developers with touch-enabled Windows devices. ---------- 1: No, not really. 2: N = 1?

* Simplify some Viewer code, and fix a few bugsGravatar Brian Osman2017-06-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The content rect was always identical to the window rect, so most of the related code did nothing. The translation limit code is always useful (to avoid dragging the slide way off-screen with the mouse), so always include it. The auto-scaling to fit the screen is also still useful, but just base it on the window rect. The zoom code has four state variables, only used two of them, and one was a trivially derived computation. Fold most of that work into computeMatrix. (The translation was always zero -- we never changed the zoom center.) Include fDefaultMatrix in the matrix from computeMatrix, rather than needing to apply it specially to the canvas. Don't apply the inverse default matrix to touch or mouse points. The absolute positions of those touch points is not important, but because that matrix includes scale (and sometimes very large or very small scale), it just had the effect of greatly amplifying or damping the drag speed. Without it, the slide always pans at the speed of the touch/mouse drag -- which seems more desirable. The use of the inverse default matrix was a clever trick, but it caused the translation (applied to the global mtx) to be scaled, so the slide was always pinned incorrectly. Instead, supply the unmodified window rect and the default matrix, so the trans limit code can do the obvious correct thing: xform the slide bounds completely, then limit the translation that will be applied after that. Slides are now correctly pinned to screen edge regardless of how much zoom is present in the default matrix. Note: There are still several bugs related to all of this code, but given the web of xform state, it's hard to unravel. The touch gesture still doesn't know about viewer's zoom, so that's ignored when doing the pinning. Beyond that, it doesn't even know about window resize - it only configures the translation limit when setting up a slide. I had a fix for all of this (doing the translation limiting in computeMatrix), but then the touch gesture doesn't know about it, and can accumulate drag motion that needs to be un-dragged to get back on-screen, even though the slide is never really translated that far. SkTouchGesture is in include. No one uses it except viewer: TBR=bsalomon@google.com Bug: skia: Change-Id: I460cc07c3de6d36e63826f57d359faf1facf5ab3 Reviewed-on: https://skia-review.googlesource.com/18524 Reviewed-by: Brian Osman <brianosman@google.com> Reviewed-by: Yuqian Li <liyuqian@google.com> Commit-Queue: Brian Osman <brianosman@google.com>

* Change SkTime::GetMSecs to double; ensure values stored in SkMSec do not ↵Gravatar benjaminwagner2016-03-25
| | | | | | | | | | | | | | | | | | | | | | | overflow. The following are currently unused in Android, Google3, Chromium, and Mozilla: - SkEvent - SkTime::GetMSecs - SK_TIME_FACTOR (also unused in Skia) - SkAutoTime I left uses of SkMSec more-or-less intact for SkEvent, SkAnimator, and SkInterpolator. SkInterpolator is used in Chromium, so I did not want to change the API. The views/ and animator/ code is crufty, so it didn't seem worthwhile to refactor it. Instead, I added SkEvent::GetMSecsSinceStartup, which is likely to be adequate for use in SampleApp. I also left SkMSec where it is used to measure a duration rather than a timestamp. With the exception of SkMovie, which is used in Android, all of the uses appear to measure the execution time of a piece of code, which I would hope does not exceed 2^31 milliseconds. Added skiatest::Timer to support a common idiom in tests where we want to measure the wallclock time in integer milliseconds. (Not used in tests/PathOpsSkpClipTest.cpp because it redefines things in Test.h.) Removed tabs in tests/StrokerTest.cpp. BUG=skia:4632 GOLD_TRYBOT_URL= https://gold.skia.org/search2?unt=true&query=source_type%3Dgm&master=false&issue=1811613004 Review URL: https://codereview.chromium.org/1811613004
