We are implementing to display animation timing-function in bug 1210795. In the bug, we display the result of effect easing as the graph. However, the graph shows 'linear' lines because animation-timing-function is executed as keyframe easing.

Inspector bug triage (filter on CLIMBING SHOES).

Just some notes from today's discussion with Daisuke. * We want to basically sample keyframe easing and have it show up in the summary graph. * 99% of the time, keyframe easing will be the same for all properties but sometimes it will differ by property. * For the differing case, we overlay the different property curves and make each semi-transparent. e.g. if we have three curves, we make all three have opacity: 0.33. That way, in places where the curves are equal, the graph is completely solid. * We *don't* want to reflect the actual keyframe property values or their distances in this view, it's just timing--that way if multiple different properties have the same easing, their curves will overlap precisely even if their values are quite different. One idea for doing this is to take something like: @keyframes hoge { 0% { opacity: 0; transform: scale(0.5); } 0% { animation-timing-function: steps(2); width: 200px; } 50% { opacity: 0.7; } 100% { opacity: 1; transform: scale(1); width: 300px; } } And sample the result of getComputedStyle(elem).opacity with the following different animations: // Opacity { offset: 0, opacity: 0, easing: 'ease' } { offset: 0.5, opacity: 0.5, easing: 'ease' } { offset: 1, opacity: 1 } // Width { offset: 0, opacity: 0, easing: 'steps(2)' } { offset: 1, opacity: 1 } // Transform { offset: 0, opacity: 0, easing: 'ease' } { offset: 1, opacity: 1 } Notice how the opacity value is equal to the offset, not the actual property value since we're just interested in time. Perhaps using the getProperties() API will make this easier? Regarding the number of curves, I think we'd probably want to sort through and combine properties that have identical easing and only generate one curve for them. This is especially true if we use getProperties() since it will expand all longhands. We'd want to set the above keyframes on the same sort of animation as we currently use for generating the summary view so that we get direction, effect easing etc. applied. That's the rough idea anyway. I'm not really sure if it works yet or not.

Oh, one other thing I forgot. Currently we show effect easing in the summary view. In this bug we want to show keyframe easing for CSS animations/transitions. That presents the question: what if an animation has both? This could happen for script-animations or even for CSS animations/transitions (you can use the script API to add effect easing to a CSS animation/transition). We both agreed that we should show both in the graph (i.e. sample the curve with both set on the animation); that it would be confusing if one type of graph showed one type of easing only. In the case where we have a non-linear effect easing and at least one keyframe with non-linear easing, I suggest we add a dotted line to represent the effect easing. Then, when we come to editing, any controls we surface for adjusting the effect easing (in the summary view) could be easily understood as adjusting that dotted line. (I assume we'd adjust keyframe easing in the keyframe view.)

I have made a prototype. The summary graph displays as following. * Display ffect easing as stroke. * Display keyframe's easing as semitransparent fill. This change can be not only for CSS Animation, but Script Animation and Transition. Thanks.

Hi Patrik, I wrote some patches for this. These patches assume on the codes of bug 1210796. Although the bug is not landed yet, could you review these patches? Thanks.

I have a few comments, and I haven't yet tested this locally. So here's a first review at least. ::: devtools/client/animationinspector/components/animation-time-block.js:24 (Diff revision 1) > // Show max 10 iterations for infinite animations > // to give users a clue that the animation does repeat. > const MAX_INFINITE_ANIMATIONS_ITERATIONS = 10; > > +// Minimum opacity for semitransparent fill color for keyframes's easing graph. > +const MIN_KEYFRAMES_EASING_OPACITY = .5; Can you explain why .5 please? If there are 3 graphs, then they will each be 50% transparent, instead of 33%. Is this wanted? ::: devtools/client/animationinspector/components/animation-time-block.js:294 (Diff revision 1) > + graphHelper.setClosePathNeeded(false); > + renderGraph(parentEl, state, totalDisplayedDuration, "effect-easing", graphHelper); > +} > + > +/** > + * Render effect easing graph.

If so, it can't be used as a key for `this.tracksMap` since it's just a plain old object, it can only have string keys. Unless, I guess, it has a toString that generates something unique. You could otherwise make `this.tracksMap` a WeakMap instead. ::: devtools/client/animationinspector/components/animation-timeline.js:517 (Diff revision 1) > - // Display animation's detail if there is only one animation, > - // or the previously displayed animation is included in timeline list. > if (this.animations.length === 1) { > - this.onAnimationSelected(null, this.animations[0]); > - return; > - } > + // Display animation's detail if there is only one animation, > + yield this.onAnimationSelected(null, this.animations[0]); > + } else if (!this.animationRootEl.classList.contains("animation-detail-visible")) { It's a little weird having an empty `else if` in the middle here.

Is this parameter ever non null? Looking at the only place where you instantiate a `SummaryGraphHelper`, I see it is null. And then later you call `setKeyframes`. If this is the case, then, you can remove the parameter altogether and just call `setKeyframes`. ::: devtools/client/animationinspector/graph-helper.js:271 (Diff revision 1) > + this.progressValueHelperFunction = this.getProgressValueHelperFunction(); > + this.opacityValueHelperFunction = this.getOpacityValueHelperFunction(); Setting these 2 properties seems unnecessarily complex. In fact, even setting `this.valueHelperFunction` doesn't seem needed. You could, at the end of `setKeyframes`, do something like `this.hasFrames = !!frames;`. Then, inside `getSegment`, you could simply do: `const value = this.hasFrames ? this.getOpacityValue : this.getProgressValue();` You would also need to make `getProgressValueHelperFunction` like this instead: ``` getProgressValue: function () { return Math.max(this.animation.effect.getComputedTimeing().progress, 0); } ``` Same for `getOpacityValueHelperFunction`. This way, you can delete `this.valueHelperFunction`, `this.opacityValueHelperFunction` and `this.progressValueHelperFunction`. Seems easier to understand to me. ::: devtools/client/animationinspector/graph-helper.js:325 (Diff revision 1) > + /* > + * Set animation behavior. > + * In Animation::SetCurrentTime spec, even if current time of animation is over > + * endTime, the progress is changed.

I will attach the screenshot. > `animation` is an object, right?

Thanks, will use WeakMap. > If I understand correctly, this class is used in just one place, and isOriginalBehavior is set to true. So we maybe don't need to expose this at all. Maybe let's just always behave as if isOriginalBehavior was true, but remove the property altogether, the if/else further below, the setOriginalBehavior, and the extra parameter in the constructor. This is used to create a graph shape for negative delay and negative endDelay in end of renderGraph. However, same to setKeyframes, we can remove a parameter from the constructor. Thanks! > Is this function used in other places than inside `SummaryGraphHelper` now? > If not, then you could move the code inside `SummaryGraphHelper.appendPathElement` instead of having a separate function here. We are using this function in keyframes.js to create detail graphs. However, I am thinking ProgressGraphHelper should have appendPathElement as same to SummaryGraphHelper for consistency of how to use. I'll do this in another patch.

I attach a screenshots to compare the opacity. One is divided by length of type of keyframe's easing. Another one is minimum 0.5 How do you think? The screenshots were taken using following JS code. div.animate([ { offset: 0, opacity: 0, easing: "steps(5, start)" }, { offset: 0, backgroundColor: "red", easing: "steps(2)" }, { offset: 0, width: "300px", easing: "steps(3)" }, { offset: 0, color: "red", easing: "steps(4)" }, { offset: 0, height: "300px", easing: "steps(5)" }, { offset: 0, marginTop: "300px", easing: "steps(6)" }, { offset: 0, marginRight: "300px", easing: "steps(7)" }, { offset: 0, marginBottom: "300px", easing: "steps(8)" }, { offset: 0, marginLeft: "300px", easing: "steps(9)" }, ], 1000 * 10);

Comment on attachment 8854655 [details] Bug 1309468 - Part 1: Display effect easing curve and keyframes easing curve in summary graph. https://reviewboard.mozilla.org/r/126594/#review135672 I've applied this commit locally and tested it a little bit. First of all: wow! Really cool to see curves and steps instead of lines. I think this helps a lot. Here are a few comments about the UI: - I tested with an animation that used steps(): http://s.codepen.io/rachelnabors/debug/zHeir and the summary graph looked a bit weird. I think it showed only 1 third of the steps as real "steps" in the graph, the other steps were straight lines. See here: https://www.dropbox.com/s/cqdmfik8j7pxjcn/steps-function-summary-graph.PNG?dl=0 --> It would be good to fix this in this patch if possible. - Now that the summary graph is becoming even more important than before (its shape conveys a lot of information), the animation name is getting in the way. It is displayed on top of the graph and could hide some important information. You are making the row height bigger now, so I would like to suggest a change in this bug. Something like this: https://www.dropbox.com/s/0iee418ub50fvx1/move-animation-name-above-target.PNG?dl=0 This way, the animation name just sits inside the sidebar, next to the target (where there is room, because we're making each row taller). Doing this will require to make sure there's an ellipsis if the name is wider than the sidebar. --> This can be done in another patch - There's often a horizontal scrollbar in the animation panel that shouldn't be there. https://www.dropbox.com/s/e5nrx638eqqvo62/horizontal-scroll-bar-animation-panel.gif?dl=0 . To reproduce this, you can go to apple.com., and just move your mouse over the top menubar. This triggers a lot of transitions, and quickly ends up creating a scrollbar in the animation panel. I don't think this is related to this commit, this might actually have been there from before. Feel free to file another bug for this if you prefer.

So I think we should use --toolbar-height here rather than --detail-animation-height. Also, why do we have both a min-height and a height?

(And, I'm sorry for my late replying..) 1. steps() problem Okay, I'll fix in this patch. 2. Animation name label I see, will try to put above the target object in another patch. (Or, it may work just put after the taget?) 3. Horizontal scrollbar It could reproduce in Nightly, but not Release(53.02) The cause may be bug 1210796. I'm sorry, will fix in this bug. Thanks!

I taken some screenshots for name label. Above the target: I feel it is crowded a bit. I wonder we may need more height? After the target: Looks not so bad for me. However, it might be vanished since depends on the label width. If the boundary of between right pane (graph) and left pane (labels) is movable, it might be resolved. Center on Graph: Also, not so bad, I think. This similar to Chrome one. How do you think?? Also, this design might depend on bug 1210363 ( animation grouping ).

Brian and I discussed about the name label design. We attach another screenshot. It is similar to type of "center of graph", but the label has outline stroke.

Minor change: stroke-opacity: 1 -> 0.5 stroke-width: 3 -> 4

And another one, put the label to end of the graph. I'll write a patch with this prototype.

Your screenshot looks good, but in many cases target DOM elements and animation names will be long so we won't see much of it. Indeed, making the left panel resizable would solve this. > Center on Graph: > Also, not so bad, I think. > This similar to Chrome one. I'm still afraid that this might hide important visual information, but it does look good in your screenshot. > How do you think?? Let's not worry about this now. As I said before, we can do this in another bug. And we can work with UX a bit to iron the details out. So, if you want to move the label to the middle, and use a stroke like comment 29, that's fine with me. We can then change it again later if we think it's necessary.

Looks good to me. One idea though: what about making it centered in the timeline. So that all labels are always aligned at the center of the whole timeline, not just inside their own graphs, which may vary in size.

Ah sorry, I hadn't seen this one. Looks good to me. Either that or centered in the timeline would be OK to me.
