Images aren't resizable in IE8 about fabric.js

[polarblau]

fabric.js looks really awesome, but not being able to scale or move images in IE7/8 would be pretty much a show stopper for me. Are there any forks or work–arounds existing which tackle this problem? Cheers!

[kangax]

Not that I know of :(

The problem is that fabric relies on excanvas in non-canvas-capable (but VML-capable) browsers like IE7 or 8.

Last time I looked into this issue, I couldn't figure out why excanvas doesn't render image properly (after rotation)/.

IE9 works as expected, but I understand that IE7/8 support for this could be very crucial.

I'll look into it once again, asap.

awsome

Is anyone working on this?
I think this is crucial but I'm kinda lost trying to find the problem.

[kangax]

IIRC, I ran into excanvas limitation last time I looked at it. Does
excanvas support drawing image with custom transformation?

Any developments on this issue?
I checked excanvas, transformations were apparently introduced in r46.

[raichu]

Just tried it using IE7 and IE8 modes of IE9, transformations worked okay.
Can someone confirm these results with real IE7 and IE8?

As far as I know, the bug is still in excanvas (you can see a link to it and more in https://github.com/kangax/fabric.js/wiki/Fabric-limitations-in-oldIE)

There's an unofficial patch that supposedly fixes it but I haven't had a chance to try it yet. If anyone can try it and confirm, that would be great!

[raichu]

Tried the tests in http://dev.sencha.com/playpen/tm/excanvas-patch/, they pass fine on real IE6 (XP).
Unfortunately, the patch is't applied to the upsteam, so maybe fabric.js can maintain it's own version of excanvas.js with the patch applued?

[kangax]

@raichu Thanks for looking into it. I applied the patch to excanvas.js that we had under /lib. Surprisingly, it applied clean. I then checked in IE8 mode under IE10 (in virtual machine) and while I see that image sizes now seem to be respected (yay!), the position still seems to be defunct. I can move bounding box, but the actual image is always rendered in top/left corner. You should be able to see this on fabricjs.com, which I updated with newly-patched excanvas.

[raichu]

Wow, I never thought it would be default on fabricjs.com so quickly --thanks!! I just fired up the patterns and controls demos (real IE6, under XP), and everything works just fine. I can move, rotate and scale the image without problems (except I'm getting the wrong mouse cursor when scaling while keeping the aspect-ratio at the corners, but it probably doesn't have anything to do with the canvas). Maybe the IE8 mode isn't really realiable?

[kangax]

Yeah, IE8 mode could definitely be the problem. I'm glad to hear it's
working for you on IE6. Do you have a way of checking on real 7 and 8?

Works even better on IE7 (XP): the mouse cursor is the correct one. I'll try to test it on IE8 as well, but I think it'll all be okay.

[kangax]

Cool. I'm closing this then. If anyone else can confirm, that would be great.

[kangax]

Now, if we could make other stuff work :)

[Kienz]

I tested it on real IE8 (Win 7) and it worked (rotate, move, scale).

[kangax]

That's great, thanks for confirming @Kienz!
