I’m happy putting Mylyn’s screen capture facility wherever it would have the most resources to be maintained and improve, as long as Mylyn can still continue to evolve it for its purposes of bug reporting and task sharing.

 

The main UI question that I think are relevant here is what the resulting UI and API should be, we’ve encountered two options:

1) Wizard style UI: very simple facility that takes a screen capture input (either via a desktop capture facility or clipboard), allows the user to do a crop step, and then another preview or markup step.  This is Mylyn’s current UI (see http://www.eclipse.org/mylyn/new/ and look for “screen”).

2) Editor style UI: supports more features such as those in commercial tools like SnagIt, imposes additional complexity of an undo/redo and save lifecycle.

 

It is also feasible to extract what we currently have to support both UIs, but (2) would likely require a significant commitment of resources in order to get the UI and overlap with workspace resources working well.  Either way, I’m happy exploring how to generalize what we have.  In terms of next steps, the following could work well:

1) Someone files a bug against Mylyn on generalizing our screen capture facilities

2) Mylyn takes the first step in generalizing it, then the reporter attempts to build on the provisional API and we iterate

3) Once there are two working clients to the API (Mylyn and the reporter’s) we figure the best home(s) for the API (e.g. very generic stuff in SWT or Platform/UI and UI specific to tasks/bugs in Mylyn).

I also think a image viewer editor would be/is fine...but IMHO also needed is some sort of consistent capture shell/dialog (i.e. to select screen region, entire display, window, or even view...with optional/configurable time delay and maybe some feedback during region select)...so that different UI isn't created for different serialization/persistence situations (e.g. save to file, send to buddy, add to task, etc).

I'm not completely sure a capture dialog goes with an image viewer...although I suppose it could.  From our point of view the most desirable thing would be minimal dependencies, so it could be used in multiple contexts (i.e. not just in IDE/workbench).

That's exactly what I was saying in that bug report ;)

I think this is what we should shoot for. I want the base image viewer/editor stuff committed and then we can work on extensions. It should probably be moved to it's own plug-in IMHO too

Cheers,

Would it make sense to put this functionality into (or next to) Eugene's image viewer? See https://bugs.eclipse.org/bugs/show_bug.cgi?id=155323

I don't think we need a global toolbar or menu item for this in every product based on the IDE. But I understand that it would be good to have a hook in Platform IDE so that the various downstream projects or products can avoid duplication.

Hi Remy, Chris, Boris, and Mik,

Remy...

I took a look at the screen capture add on to the collab example code,
and the problem that you (Remy) previously experienced was due to
limitations on the object serialization for very large objects
(ImageWrapper when the image data array was very large [i.e. 200Kbytes+,
etc]).

I added some basic compression (using zip...which is probably not
optimal, but does help), and added protocol to send the data as a set of
messages (see EclipseCollabSharedObject.sendImage) instead of a single
large message, and it works. I also did some other mild refactoring in
line with bug
https://bugs.eclipse.org/bugs/show_bug.cgi?id=160633 .
Obviously this was just done, so it's not yet in a
distribution/milestone release.

The reason I'm writing this to Remy, Chris, and Boris, is that I would
like us to consider adding more/better UI for doing screen capture (and
display of received screen captures)...and I would like to use this new
UI to also build in support for sending bits via the ECF datashare API
as well (so that screen shares can be done directly between people on
your buddy list as well as within collab session...i.e. via skype, xmpp,
etc). I imagine most of you have probably seen this blog posting:

http://www.jroller.com/eu/entry/capturing_screenshots

Perhaps we could use this as an opportunity to work with the Mylyn folks
(who already have a screen capture UI as in the posting, but arguably
should be better/generalized in line with some of their enhancement
requests), and perhaps the SWT/JFace/Platform UI folks (Boris?), or even
some of the Jazz folks (Chris?).

Clearly, it would be nice for all involved to have a consistent screen
capture UI, that then we (ECF) could add the ability to send the
captured image to buddies, and/or collab group members. Obviously, this
is a very common user desire/activity (exchanging screen shots)...which
is certainly why it's being built into Jazz, Mylyn, ECF, probably
others, etc., etc.
