Description

Currently ReviewBoard has a limited way of rendering SVG files and does
not allow for proper scaling and zooming. We are now attempting to utilize
SVG potential to full extent and allow users to inifinitely scale/zoom SVG images.

The new solution utilizes viewBox attribute of SVGs and attempts to manipulate it
in order to create zoom-in ability and ability to span SVG. Moreover, the solution
also dynamically rescales and adjusts comment boxes based on the viewBox.

Currently, the new features only apply to a single image, i.e. no diffs view.
The diff view with SVGs will behave the same way as with the bitmap images.
However, there is no ability to zoom in/out or span the SVG.

Testing Done

The UI was tested using Google Chrome and Safari.

Unit tests were but no additional tests were added.

This event is getting ignored completely and I am not super sure why. The only reasoning I could find was that the event does not get triggered if the views are nested.

This event works. I have tried this because I wanted to see if mousewheel event works at all. So my best guess (from another comment), is that events get cancelled out when views are rendered in nested approach.

This is listening for events on an element with the image-diff-attachment which is a child of the current view, but it looks like this view is attached to an <img> with no children. You probably want to just change the key to be mousewheel.

akim.ruslanov Oct. 16, 2021, 5:17 p.m.

So I tried that, but the same issue persists...

akim.ruslanov Oct. 16, 2021, 5:58 p.m.

So after some more research, I found out that the events in subviews might be killed during the re-rendering of the views or swapping them out. I tried using this._imageView.delegateEvents() but it didn't help either. Perhaps, I was misusing this method or am I misunderstanding the reason why the event is getting triggered?

Change Summary:

Event handling for mousewheel is now handled in
parent view and then relayed to child view.

This function's sole purpose is to change viewBox value for the SVG based on the values passed from the parent view. One thing I am struggling to understand is to how correctly change the src value of the image. The current implementation is based on loadImages function. This works perfectly fine but I can't explain completely why.
The part I am most confused about is why does line 334 trigger image.onload.

david Nov. 2, 2021, 1:06 p.m.

Changing the src attribute makes the browser "load" a new image, even if it's technically the same source file as before. One of the things about SVG is that the entire structure of the image is accessible via the DOM, so I'd look into drilling down into the element to see if there's a different way to change these attributes without completely reloading the image.

akim.ruslanov Nov. 3, 2021, 11:25 p.m.

So I think I found a way to change the viewBox without reloading the image. However, this eiter requires using invline SVG or using iframe/object tag. I am not super sure if inlining is possible due to caching issues, while iframe/object tags requires changing web configs. I am not sure if it's worth doing since the current implementation seems to be working properly for now.

akim.ruslanov Nov. 4, 2021, 12:11 a.m.

Actually, I kinda figured it out. I can change the src using $el.attr(). I am pretty sure it's not reloading the image every single time anymore. Will post updated code asap

akim.ruslanov Nov. 4, 2021, 12:27 a.m.

NVM, found out that this also triggers reloading... So still kinda stuck

Problem with zoom in and commenting (Revision 1)

Show all issues

Is this an expected behaviour, or should the comment also change its position based on the zoom in/out of SVG?

akim.ruslanov Nov. 2, 2021, 12:28 a.m.

Just realized that on the comment, you cannot see it, so please open the actual GIF

david Nov. 2, 2021, 12:40 p.m.

We should definitely be scaling the comment outlines when scaling the image.

Change Summary:

Added a button to switch between spanning and commenting.
Added an ability to drag SVG using mouse

As far as I understand, the main purpose of loadImages and onImagesLoaded is to ensure data like initial-width and scaling is correct on render.

What I am trying to do right now is to dynamically inline SVGs by fetching the data and parsing it using the DOMParser. This will allow me to use SVGElement API that's somewhat necessary for correct scaling, dragging and zooming. Should I be dynamically inlining the SVGs in loadImages or should that be done before any rendering even begins?

Change Summary:

Possibly need to inline SVG to use
the SVGElement API. Trying to figure
out if this is possible

In order to inline the SVG, I need to asynchronously fetch them and use the parser after. However, if I do it like this, then the renderring of the image happens couple of seconds after the rest of the page got rendered. In addition, since we run some methods on the element, they fail since it didn't finish rendering. Any thoughts on how to combat that? I was thinking of maybe fetching the data in backend, or perhaps there is a way to fetch it in the model?

chipx86 Nov. 22, 2021, 6:26 p.m.

It'll need to happen on the frontend. Maybe put up a spinner before fetching, remove it after fetching? I could see this being an issue for more than just SVGs down the road, so having a way to say "I'm triggering a load of the image" and then "I got it, we can set things up now" would be good.

OK sounds good!
```

akim.ruslanov Nov. 22, 2021, 6:33 p.m.

Also, as a quick follow up, does any view/element of RB have something that has a spinner already? Just wanna make sure I am following the same UI pattern as everything before

chipx86 Nov. 22, 2021, 8:55 p.m.

Yep. We do have an older spinner style that you'll find, but grep around for djblets-o-spinner and you'll see the modern one we're migrating over to.

Change Summary:

Finished migrating to SVGElements API.
Now any scaling, zooming or dragging happen
by changing the viewBox value directly.

Description:

		Currently ReviewBoard has a limited way of rendering SVG files and does
		not allow for proper scaling and zooming. We are now attempting to utilize
		SVG potential to full extent and allow users to inifinitely scale/zoom SVG images.

		The new solution utilizes `viewBox` attribute of SVGs and attempts to manipulate it
~		in order to create zoom-in ability.
	~	in order to create zoom-in ability and ability to span SVG.

Can we call this svgPromise, just so people definitely know that it's a promise and not data?

akim.ruslanov Dec. 1, 2021, 6:55 p.m.

Changed the variable to this.svgPromise. Should the name of the method also change, or is fetchSvg() clear enough? In my mind, fetch is always async (unless explicitly said otherwise) so any fetch type function will return a Promise

chipx86 Dec. 6, 2021, 2:56 a.m.

I think fetchSvg() is fine. It's more about identifying the type of the variable, to make it clear.

This looks like it's not actually a jQuery object, so we shouldn't use the $ in the variable name.

Let's split this up:

};

fetch already is a promise, so this whole thing can just be:

return fetch(this.model.get('imageURL'))
    .then(res => res.text())
    .then(data => {
        const parser = new DOMParser();
        return parser.parseFromString(data, 'image/svg+xml')
            .querySelector('svg');

Can you explain this? Is this a TODO or FIXME? (if so, please use that text so it's searchable). This comment should also probably go inside the body of the function instead of above it.

This needs some blank lines to make it less dense. Comments also need to start with capital letters and end with periods.

This shouldn't need async

akim.ruslanov Dec. 1, 2021, 6:55 p.m.

Since getSelectionRegion() is async for the SvgAttachmentView, I am using await for it. That's why I put async there

Did you test this with normal image attachments?

akim.ruslanov Dec. 1, 2021, 6:55 p.m.

Yes. In the case with normal image, this._imageView.getSelectionRegion is synchronous, so await does not really do anything here. So this whole code block just behaves synchronously

This can use addClass. Also, please use single quotes:

akim.ruslanov Dec. 1, 2021, 6:55 p.m.

In this case, I am trying to toggle the icon by changing the class, that's why I am using attr. If I change it to addClass it will no longer toggle the icons. Or am I misunderstanding your comment?

chipx86 Dec. 6, 2021, 2:56 a.m.

Description:

		Currently ReviewBoard has a limited way of rendering SVG files and does
		not allow for proper scaling and zooming. We are now attempting to utilize
		SVG potential to full extent and allow users to inifinitely scale/zoom SVG images.

		The new solution utilizes `viewBox` attribute of SVGs and attempts to manipulate it
~		in order to create zoom-in ability and ability to span SVG.
	~	in order to create zoom-in ability and ability to span SVG. Moreover, the solution
	+	also dynamically rescales and adjusts comment boxes based on the `viewBox`.
	+
	+	Currently, the new features only apply to a single image, i.e. no diffs view.
	+	The diff view with SVGs will behave the same way as with the bitmap images.
	+	However, there is no ability to zoom in/out or span the SVG.

Testing Done:

		The UI was tested using Google Chrome and Safari.

~		No unit tests were run yet and no additional tests added.
	~	Unit tests were but no additional tests were added.

Fix it!

This feature is great! Now, I have a lot of comments here. Most of them have to do with coding style standards (trailing commas, blank lines, indentation, ordering, etc.). The kind of things that make a review large, but will help the code really fit and stay maintainable once complete.

There is a bigger note in here, and I'd take it on after the stylistic stuff so that those bits are less distracting. That note has to do with the UI. I think what you had was great for development, but buttons that toggle their behavior when clicked is problematic, for reasons I'll outline below.

Show all issues

The new toolbar seems to be SVG-specific. It would be ideal if the ability to zoom, pan, etc. could be done on bitmap as well. Is that possible? If not, what would be required to make that happen (as work for after this goes in)?

Ideally, we'd end up with one unifying interface that was common regardless of image type.

UI elements to control SVG (Revision 3)

Show all issues

In UI, discoverability is important. A person should ideally be able to see what options are available before having to interact. In this case, we have two icons that each conceal an alternate state, with no way (aside from trial-and-error or reading documentation) to know about that state.

I'd suggest splitting each of these into two buttons (with some separation between them to help show the grouping), and use a visual indicator to show which is selected (such as a background color that makes it clear which is active).

That way, a person will see their options up-front, and can choose them without having to remember what happens when they click each thing.

This is also really important for accessibility. If a person is using a screen reader, they'll have an even more difficult time selecting the desired action.

Can you separate the variable declarations from the modifications?

Think of code like paragraphs in a book. What is each paragraph trying to communicate? Is it a big dense paragraph that's trying to say many things, or does each have purpose?

I see the following paragraphs in this function:

We're determining the scaling based on stored state.
We're telling the element what its size should be.
We're telling the SVG what its new size and viewBox should be.
We're setting new state on the iew.

The class names used in this block of HTML are very generic. Not your fault — that's pretty common in a lot of our legacy code. We're trying to fix this with our CSS Component style: https://reviewboard.notion.site/CSS-LessCSS-Component-Style-Guide-ceb55ed87d954101a074f6601fc5deb2
You're not going to be able to retrofit all this onto that. No problem. Let's namespace these classes, though, and call them:

rb-c-image-review-svg-toolbar
rb-c-image-review-svg-toolbar__pan
rb-c-image-review-svg-toolbar__zoom
rb-c-image-review-svg-toolbar__drag
rb-c-image-review-svg-toolbar__comment

Our UI for image review isn't very accessible-friendly (ignore for a moment that the concept of reviewing a visual medium sort of isn't either).

Still, we want to make forward progress on any new UI. These actions need to be presentable to screen readers or any other accessibility tools. We can do that by:

Telling the screen reader these are effectively buttons (role="button")
Giving them a title/tooltip (title="...") — basically what you'd want to see as alternative text for the icon, if the icon could not be shown.
Turn off reading of the icon (aria-hidden="true")
